Toure, Zikra. "Human-Machine Interface Using Facial Gesture Recognition." Thesis, University of North Texas, 2017. https://digital.library.unt.edu/ark:/67531/metadc1062841/.
Full textAbstract:
This Master thesis proposes a human-computer interface for individual with limited hand movements that incorporate the use of facial gesture as a means of communication. The system recognizes faces and extracts facial gestures to map them into Morse code that would be translated in English in real time. The system is implemented on a MACBOOK computer using Python software, OpenCV library, and Dlib library. The system is tested by 6 students. Five of the testers were not familiar with Morse code. They performed the experiments in an average of 90 seconds. One of the tester was familiar with Morse code and performed the experiment in 53 seconds. It is concluded that errors occurred due to variations in features of the testers, lighting conditions, and unfamiliarity with the system. Implementing an auto correction and auto prediction system will decrease typing time considerably and make the system more robust.

Farneland, Christian, and Magnus Harrysson. "Developing a Human-Machine-Interface with high usability." Thesis, KTH, Data- och elektroteknik, 2016. http://urn.kb.se/resolve?urn=urn:nbn:se:kth:diva-188499.
Full textAbstract:
When developing a Human-Machine-Interface (HMI) it is important to make sure that it is easy to learn and use, to have high usability. If it does not, the operator of the machine suffers unnecessarily and it also becomes harder to sell for the producer of the machine. The effectiveness and efficiency of the machine drops down when it is hard to operate. To make it easier for future developers to reach a high usability factor when developing a HMI, this thesis aimed to find a carefully prepared process to follow when doing so. The result was a process that was tested out with a HMI prototype for waterjet cutting machines. This prototype was then tested in different use cases by both experienced operators as well as beginners. The testing produced positive feedback on the prototype, proving that the process that had been followed was being successful.När man utvecklar ett Människa-Maskin-Gränssnitt (HMI) så är det viktigt att se till att det är lätt att lära sig och använda, att det har hög användbarhet. Ifall den inte har det så försämrar det operatörers situation i onödan och gör det svårare för producenter att sälja produkten. Produktionseffektiviteten minskar ifall maskinen är svår att hantera. För att göra det lättare för framtida utvecklare att nå en hög användbarhet när de utvecklar ett HMI så siktade detta examensarbete på att hitta en genomtänkt process att följa vid ett sådant tillfälle. Resultatet blev en process som testades via en HMI prototyp för vattenskärnings maskiner. Denna prototyp blev sedan testad i olika användarfall av både erfarna operatörer och nybörjare. Testerna visade sig ge positiv återkoppling, vilket bevisade att processen som följts upp till den punkten fungerade.

Full textAbstract:
For the drivers of heavy trucks, performing some maneuvers with high precision could be a challenging task even for experienced ones. Volvo has a system which helps drivers in reversing the truck. Developing a human machine interface on a mobile platform with high usability for this system could help drivers to decrease both the stress level and spent time on maneuvering and will result in performing the task easier. This thesis introduces a new area in safety critical systems by combining automation with a mobile platform. An iterative and user centered design process utilized and three main iterations performed. In first iteration a low-fidelity prototype was created and evaluated by performing user tests. The output of usability test used to implement the software prototype for the second iteration. Evaluation of software prototype was done by desktop testing. In third iteration, second version of software prototype evaluated by performing field testing. Android and Google maps were used to implement three tasks: Destination, Rewind and Saved point. In all these iterations usability and safety were two main concerns and considered by looking into guidelines and performing evaluations. In the final test, the prototype was evaluated considering four usability factors: satisfaction, learnability, safety and achievement. After analyzing these factors prototype showed strong potential for a future product.

Thesis: S.M., Massachusetts Institute of Technology, School of Architecture and Planning, Program in Media Arts and Sciences, 2018.Cataloged from PDF version of thesis.
Includes bibliographical references (pages 59-62).
In this thesis, we present a non-invasive and non-intrusive system that enables silent duplex human-machine communication and enables an interface that is internal to the user. We present a peripheral nerve-computer interface, AlterEgo, that allows a user to silently converse with a computing device without any voice or any discernible movements - thereby enabling the user to communicate with devices, AI assistants, applications or other people in a silent, concealed and seamless manner. A user's volitional internally articulated speech is characterized by efferent signal signatures in internal speech articulators that are captured and recognized by the proposed system. The hope is to facilitate a natural language user interface, where users can silently communicate in natural language and receive information and sensory input aurally through bone conduction. This enables a discreet, closed-loop interface with a computing device, and thus providing a seamless form of cognitive augmentation. The goal of the thesis is to describe the architecture, design, implementation and operation of the entire system along with demonstrating the utility of the platform as a personal computing system.

Considerando che una delle maggiori problematiche dei veicoli elettrici è l’autonomia della batteria, questo progetto di tesi si pone l'obiettivo di realizzare un sistema che aiuti l'utente a guidare in maniera efficiente, aiutandolo a salvaguardare la carica della batteria. In particolare, si vuole realizzare un sistema che aiuti l'utente durante le frenate. Questo sistema, tramite meccanismi di Machine Learning, dovrà predire lo stato di carica della batteria, sulla base del valore di alcuni parametri che riguardano la frenata. In base al valore predetto, il sistema dovrà poi fornire al conducente delle indicazioni, in tempo reale, su come andare a modificare la frenata. Si vogliono inoltre integrare in questo sistema anche dei meccanismi di gamification. Lo scopo è di incentivare l'utente a seguire le indicazioni proposte dal sistema, fornendogli obiettivi da raggiungere, livelli in cui progredire, la competizione con altri utenti, la condivisione dei propri successi e il guadagno di ricompense.

Elton, Mark David. "Matching feedback with operator intent for efficient human-machine interface." Diss., Georgia Institute of Technology, 2012. http://hdl.handle.net/1853/50152.
Full textAbstract:
Various roles for operators in human-machine systems have been proposed. This thesis shows that all of these views have in common the fact that operators perform best when given feedback that matches their intent. Past studies have shown that position control is superior to rate control except when operating large-workspace and/or dynamically slow manipulators and for exact tracking tasks. Operators of large-workspace and/or dynamically slow manipulators do not receive immediate position feedback. To remedy this lack of position feedback, a ghost arm overlay was displayed to operators of a dynamically slow manipulator, giving feedback that matches their intent. Operators performed several simple one- and two-dimensional tasks (point-to-point motion, tracking, path following) with three different controllers (position control with and without a ghost, rate control) to indicate how task conditions influence operator intent. Giving the operator position feedback via the ghost significantly increased performance with the position controller and made it comparable to performance with the rate control. These results were further validated by testing coordinated position control with and without a ghost arm and coordinated rate control on an excavator simulator. The results show that position control with the ghost arm is comparable, but not superior to rate control for the dynamics of our excavator example. Unlike previous work, this research compared the fuel efficiencies of different HMIs, as well as the time efficiencies. This work not only provides the design law of matching the feedback to the operator intent, but also gives a guideline for when to choose position or rate control based on the speed of the system.

For a achieving the real usability goal, the designer’s activity demands a additional toolkit for the quality evaluation of graphical and multimedia products, including quality from psychological and ergonomic standpoint. In this paper, an analysis of modern methods for assessing the effectiveness of websites was conducted and research development in the field of promotion of web-resources on the Internet was generalized. The methods of obtaining data for the quantitative assessment of visual perception, which can be used in the development of both information technology and personal identification technologies, are explored. It is revealed that with the use of cognitive technologies that take into account the peculiarities of person's visual perception of graphic information, it is possible to create effective tools and methods for the development of technological modules and completed application information systems. As a result of the work, an algorithm for improving the efficiency of UI web-systems was developed.

Full textAbstract:
This research work presents a novel neuromusculoskeletal (NMS) model of the human lower limb that is physiologically accurate and computationally fast. The NMS model uses electromyography (EMG) signals recorded from 16 muscles to
predict the force developed by 34 musculotendon actuators (MTAs). The operation of each MTA is constrained to simultaneously satisfy the joint moments generated with respect to 4 degrees of freedom (DOF) including: hip adduction-abduction, hip flexion-extension, knee flexion-extesion and ankle dorsi-plantar flexion. Advanced methods are developed to capture the human movement and produce realistic motion simulations. These are used to provide dynamic consistency to the NMS model operation. Pattern recognition and machine learning technology is used to predict the human motor intention from the analysis of EMG signals and integrate context knowledge into the EMG-driven NMS model.
This research develops the technology needed to establish an EMG-driven human-machine interface (HMI) for the simultaneous actuation of multiple joints in a lower limb powered orthosis. This work, indeed, shows for the first time it is possible to use EMG signals to estimate the joint moments simultaneously
produced about multiple DOFs and this is crucial to provide better estimates of muscle force with respect to the state of the art. This thesis also suggests the NMS model can be exploited to address the challenge of autonomous locomotion in musculoskeletal humanoids.
The objective of this work therefore, is to provide effective solutions and readily available software tools to improve the human interaction with robotic assistive devices. This is achieved by advancing research in neuromusculoskeletal modeling to better understand the mechanisms of actuation provided by human muscles.
Understanding these mechanisms is the key to realize human interaction with wearable assistive devices. This work designs and develops the technology for achieving this.Questo lavoro di ricerca presenta un innovativo modello neuromuscoloscheletrico (NMS) dell'arto inferiore umano. Il modello e' fisiologicamente accurato e computazionalmente efficiente. Utilizza segnali elettromiograci (EMG) acquisiti da 16 muscoli per predire la forza sviluppata da 34 attuatori muscolo-tendinei (MTAs). Ogni MTA e vincolato a soddisfare i momenti articolari generati rispetto a 4 gradi di liberta: adduzione-abduzione e flessione-estensione dell'anca, flessione-estensione del ginocchio e flessione plantare-dorsale della caviglia. Sono stati sviluppati metodi avanzati per digitalizzare il movimento umano e creare simulazioni motorie realistiche. Queste vengono utilizzate per assicurare consistenza dinamica durante l'esecuzione del modello NMS. Tecniche di pattern recognition e machine learning vengono poi utilizzate per predire il tipo di movimento che il soggetto umano vuole compiere attraverso l'analisi dei segnali EMG. Questa ricerca sviluppa gli strumenti necessari per realizzare un interfaccia uomo macchina (HMI) comandata da segnali EMG che consenta l'attuazione simultanea dei giunti articolari in un esoscheletro dell'arto inferiore. Viene mostrato, infatti, per la prima volta, che e' possibile usare segnali EMG per stimare i momenti articolari prodotti rispetto a piu gradi di liberta e che questo e' fondamentale per ottenere stime corrette della forza muscolare. Questa tesi illustra anche la possibilita di implementare strategie di locomozione per robot umanoidi dotati di una struttura muscoloscheletrica. L'obiettivo di questo lavoro e' quindi quello di fornire soluzioni efficaci e strumenti software avanzati per migliorare l'interazione umana con dispositivi robotici di assistenza. Questo e' ottenuto attraverso una ricerca nel campo della modellazzione neuromuscoloscheletrica per comprendere i meccanismi di attuazione propri dei muscoli uniarticolari e biarticolari umani. La comprensione di tali meccanismi rappresenta il punto chiave per lo sviluppo di soluzioni efficaci per il controllo di sistemi assistivi indossabili. Questo lavoro mette a disposizione la tecnologia necessaria per ottenere tali risultati.

Find full textAbstract:
The goal of this thesis project was to digitize a milling machine. To achieve this, a data collection system was created using current sensors connected to a PLC external to the machine's CNC control to measure the phase currents of the machine's motors.
During a period of observation, in which the machine exhibited only healthy behavior, data on the motor currents were collected by running a diagnostic cycle between the normal production cycles.
This data was then processed to develop a condition monitoring PLC application for the motors. The application allows the user to determine how similar the signals recorded are to those recorded during the collection period and in this way determine if any anomalies are present. To determine the presence of anomalies, the signals are processed using three different approaches: first they are compared to a nominal signal in the time domain, then through a classifier obtained by machine learning techniques, their harmonic content is analyzed; finally, an autoencoder is used and the reconstruction error is evaluated. Combining the results of these approaches, the final judgment on the executed diagnostic cycle is then produced.
In addition, a mobile human-machine interface has been created to allow the machine operator to visualize the produced diagnostic data, to update the production data and to monitor the machine operation through a mobile device.

Full textAbstract:
This thesis is dedicated to the development of advanced human machine interfaces (HMIs) for elderly people and people with motor disabilities such as spinal cord injury, quadriplegia and amputation. Based on an intelligent wheelchair system developed at the University of Essex, several new face movement based control interfaces are unveiled and utilized to substitute traditional joystick controllers. Color face video from a web camera is applied to track face, head and eye movements of the user. Meanwhile, the concept of multi-modality human machine interface (MMHMI) is introduced to integrate face video data with facial muscle and eye activities recorded from electromyography (EMG) and electrooculography (EOG) signals. The control interface presented in this thesis covers the state-of-the-art research progress carried out under the intelligent wheelchair project at the robot arena for the last five years. In order to test the mechanism between different wheelchair control methods, three face movement based control interfaces are deployed in indoor navigation tasks in which users are asked to drive a wheelchair following designated routes, avoid obstacle and barriers one by one. The control results are compared with traditional joystick and touch screen control methods. The performance of individual control methods is analyzed based on recorded user behavior, wheelchair trajectory, task completion duration,' and user feedback. User driving experience is collected in the form of feedback questionnaires in terms of the wheelchair control such as user comfort, interface response, control accuracy and control reliability. These can be are used to improve future wheelchair control interface design.

Full textAbstract:
The automotive sector has been the most happening industry in terms of development ever since its creation. With markets emerging across the globe in the automotive sector there are newer challenges in terms of providing new products at lesser cost but without compromising on quality. Testing cost of electromechanical components (HMI) is high and which in turn has a direct impact on the final price of the product, which they are selling it to their customers. One way to counter this issue is to outsource. The aim of this thesis is to actually provide business intelligence where by the midsize segmented automotive suppliers are benefited and the cost of testing can be reduced. The product in focus here is an electromechanical component (HMI) for commercial vehicles. The main contribution in this thesis has been the analysis & implementation of the outsourcing strategy. There were two approaches one being a theoretical approach where a market research was done to get an overview of the current trend and studying the demands of different customer for testing. The second half has been practicality implementing this data collected. Here no assumptions have been taken and the data collected has been obtained purely based on interaction with various test vendors across Europe. Cost optimization analysis was further done in order to arrive at a conclusion of preferred suppliers. Also another strategy used was by investigating possibilities for making some test in house and defining standardized test plan procedures for them. Thereby providing an overall strategy for testing with cost optimization as the main focus also leading to an edge over their competitors and increasing their market share.

Full textAbstract:
Human-machine interfaces influence both operator effectiveness and machine efficiency. Further immersion of the operator into the machine’s working environment gives the operator a better feel for the status of the machine and its working conditions. With this knowledge, operators can more efficiently control machines. The use of multi-modal HMIs involving haptics, sound, and visual feedback can immerse the operator into the machine’s environment and provide assistive clues about the state of the machine. This thesis develops a realistic excavator model that mimics a mini-excavator’s dynamics and soil interaction during digging tasks. A realistic graphical interface is written that exceeds the quality of current academic simulators. The graphical interface and new HMI are placed together with a model of the excavator’s mechanical and hydraulic dynamics into an operator workstation. Two coordinated control schemes are developed on an haptic display for a mini-excavator and preliminary tests are run to measure increases in operator effectiveness and machine efficiency.

L’obiettivo del presente lavoro è stato quello di progettare, sviluppare e creare un sistema che permettesse l’interazione tra utenti disabili e Ambiente Domotico. Le attuali tecnologie nell’ambito dell’Internet of Things, infatti, costituiscono una potenziale risorsa da poter sfruttare per la creazione di sussidi rivolti a persone affette da disabilità medio-severe; tali sussidi posso essere d’aiuto ai suddetti utenti per superare le problematiche quotidiane di gestione dell’ambiente domestico. Il sistema proposto con il presente lavoro introduce come elemento di innovazione la possibilità di interazione utente-ambiente in modo personalizzato ed assistito: il sistema, infatti, adotta un comportamento customizzato per ogni utente che lo utilizza. Tale sistema prende il nome di Personalized Assisted Human Machine Interface (PAHMI).
Il sistema è dotato di un’interfaccia grafica (Human-Machine Interface, HMI) attraverso la quale vengono presentati all’utente i possibili comandi impartibili all’ambiente circostante, rappresentati sulla HMI tramite appositi quadrati disposti in cerchio. Per raggiungere il quadrato corrispondente al comando desiderato (target), l’utente ha la possibilità di muovere un puntatore (il mouse del PC) utilizzando uno smartphone dotato di accelerometro e sfruttando il solo movimento della testa.
Per il funzionamento univoco del sistema, adattato al singolo utente, sono necessarie due fasi: una prima fase di esercizio ed una seconda fase di utilizzo.
Durante la fase di esercizio, vengono analizzate le traiettorie che l’utente impartisce al puntatore, con l’obiettivo di apprendere automaticamente le caratteristiche di comando univoche adottate dall’utente stesso. Per poter stimare le caratteristiche di comando dell’utente durante l’analisi online delle traiettorie, è stato implementato un modello classificatore denominato Support Vector Machine (SVM).
Nella fase di utilizzo, l’obiettivo è quello di aiutare l’utente nel suo intento di impartire una traiettoria desiderata e raggiungere il target; per fare ciò è stato applicato un sistema di controllo di tipo PID per il raggiungimento di un’area desiderata dell’HMI, avendo a disposizione le caratteristiche di comando dell’utente (fornite dalle SVM durante la prima fase).
Inoltre, il sistema è stato implementato fisicamente con l’hardware necessario, assemblando microcontrollori, trasmettitori WIFI e sistemi embedded, per permettere di impartire realmente i comandi all’ambiente circostante. Infine, è stato implementato un sistema software per la comunicazione WIFI tra HMI, server principale ed attuatori disposti nell’ambiente domestico.
Il lavoro proposto si è concluso con una fase sperimentale, l’analisi e la verifica dei risultati.The objective of this work is the design, development and creation of a system which enables the interaction between disabled people and Home Automation. The actual technologies in the field of Internet of Things, indeed, are a potential resource to be exploited to create aids oriented to subjects with medium-severe disabilities; such aids might help those subjects in overcoming daily struggles as for the interaction with the home environment. The system proposed in this work has as element of innovation the possibility of user-environment interaction in a personalized and assisted way: the system, indeed, behaves in a customized way for each user. This system takes name of Personalized Assisted Human Machine Interface (PAHMI). The PAHMI system has a graphic interface (Human-Machine Interface, HMI) which shows to the user all possible tasks that can be given to the environment, represented on the HMI as squares oriented in circle. To reach the square corresponding to the desired command (target), the user can move a pointer (PC mouse) using, through the head movement, a smartphone endowed with an accelerometer. For the univocal functioning of the system, adapted to the specific user, two phases are necessary: a first phase of learning and a second phase of use. During the learning phase, trajectories given by the user to the pointer are analysed, to automatically learn the specific command features adopted by the user. To estimate user command features during online trajectories analysis, a classifier model named Support Vector Machine (SVM) has been implemented. During the using phase, the objective is to help the user to exploit the desired trajectory and reach the target; to do so, a PID control system has been used to reach the desired target area of the HMI, having available the user command features (provided by the SVM during the first phase). Moreover, the system has been physically implemented with the necessary hardware, assembling microcontrollers, WIFI transmitters and embedded systems to be able to actually give commands to the surrounding environment. Finally, a software system for the WIFI communication between HMI, main server and actuators placed in the home environment has been implemented. The work proposed ended with an experimental phase and the analysis and verification of results.

Riding the tide of the rapid advances in technology in all industries, the automation industry, in particular, has been developing precision machinery with PC-Based controllers at a striking speed. Those PC-based machines provide humanized interfaces, unique functionality, and the independent capacity. They have helped organizations in increasing product diversity and in improving value-added to products processed by them. This trend has an overall impact on the machinery industry. This research is rooted on the simplified PC-Based Controller (INCON-M450S controller) developed by INTEK Company. Based on the INCON-M450S controller prototype, this research uses Visual C++ 2005 MFC framework to create a human-machine interface, which includes elements such as parameter adjustment, timing control, and content control. The resulting humanized, professional, and intelligent CNC control interface helps resolving some CNC related technical issues. Furthermore, it can assist the precision machinery industry in training and developing human capital.

Electroencephalogram is a powerful non-invasive tool widely used by for both medical diagnosis and neurobiological research because it provides high temporal resolution in milliseconds which directly reflects the dynamics of the generating cell assemblies, and it is the only brain imaging modality that does not require the head/body to be fixed. However, the lack of availability of EEG monitoring system capable of high-definition recording, online signal processing and artifact cancellation, without use of conductive gels applied to the scalp, has long thwarted the applications of EEG monitoring in the workplace. This dissertation describes a design, development and testing of a neural human machine interface that allows assessment of brain activities of participants actively performing ordinary tasks in natural body positions and situations within a real operational environment. More importantly, this dissertation also discuss the implications of this innovative mobile wireless brain imaging technology in neuroscience and neuro-technology, through three sample studies: (1) cognitive-state monitoring of participants performing realistic driving tasks in the virtual-reality-based dynamic driving simulator; (2) the efficacy and neural correlates of auditory feedback delivered to participants to maintain participants attention and alertness; (3) the neural correlates of kinesthetic sensation and perception in the dynamic driving simulator. Results of these studies provide many new insights into the understanding of complex brain functions of participants performing ordinary/routine tasks in a minimum constrained environment. These results also allow a better appreciation of the limitations of normal human performance in repetitive task environments, and may allow more detailed study of changes in cognitive dynamics in brain-damaged, diseased, or genetically abnormal individuals. Furthermore, these findings might be difficult, if ever possible, to obtain in a standard EEG laboratory where participants are asked to limit their eye blinks, teeth clinching, head/ body movements. We, thus, believe this work opens a new chapter in neuro-cognitive human-machine interface/interaction.

Recently, the technology of image process is greatly improved owing to the high upgrade of computers. The technology can be applied in a variety of applications, such as human machine interface, video compression, vehicle tracking, monitoring, and control system, machine vision…etc. In this thesis, CCD is used as the input image. The function of human face tracking to identify the moving direction is achieved as human machine interface. Users can control the four directions by moving direction of their face. The system of human face tracking is separated into two parts, i.e., detection and tracking. The detection part in this thesis is performed manually. The human face tracking proposed in this thesis is based on motion estimation. Block matching is often adopted for motion estimation. The process of comparing every block is quite time-consuming, although it is accurate. In order to reduce the size of search window, we perform search prediction by straight-line motion. To reduce the amount of comparison, we adopt KLT corner detection and perform the search only on the interested regions. So in this research, we can implement the tracker in real-time. For real world application, the human face tracking algorithm is implemented on a game station.

Nowadays, Taiwan's industrial development has moved from the traditional industry to the high-tech industry. The government has also tried to establish the image of Taiwan as a new technology island in the international arena. And, the development of human resources has also moved from labor-intensive to technology-oriented. The labor cost has become more and more expensive. To meet the need to reduce labor costs and achieve high added value, the human-machine interface is a good choice. A good human-machine interface can make the computer software and hardware work with the users, and let the users enjoy it. Different backgrounds of the users can clearly know what the computer systems can do for him and help him meet his needs step by step. The users also can predict how the computer will be responded to his operation. This shows that the user can easily outline the interactions that should be made with the computer systems. Otherwise, the users don’t feel that the computer system cannot communicate and cause fear, anxiety and so on. When users use the computer system to complete their work, they are completely dominated by the interactive model adopted by the computer software. For example, the computer can operate by mean of text commands or can be operated by questions, answers or menu. In the current window system, most of the direct manipulation methods are used to interact. Once the computer systems decide to use a certain control mode, the appearance of its interface and operation of users has been greatly restricted. Among the above modes, the maximum flexibility is directly manipulated. However, if the software interface in this way is not completely designed, it is the interface that is most likely to be overwhelming to the user. The touchscreen is a very important component in the design of a friendly human-machine interface, so this paper will use a microcontroller to control the temperature sensor and design an interface that can display and record temperature on the TFT-LCD touch panel.

It is common to own a car in modern society. The in-vehicle human-machine interface allows drivers to conveniently set or provide vehicle information. However, in the actual driving process, it is inevitable that the driver will touch the in-vehicle system, and their eyesight will leave the road in the process. If they unfortunately encounter and emergency situation during this period, it will be hard to react in time and cause a traffic accident, causing the drive to be injured and lose assets at the same time. This study uses the Android system platform and takes lighting and environmental factors into consideration. Infrared camera and infrared lamps are used with multiple image processing methods, including facial recognition, skin color detection, gray scale conversion, median filter, morphology, thresholding, edge detection, and Hough circles detection. The eye image is cut out through proportion of interest and the image is analyzed for iris and eye corner information, which is used to calculate changes and define events. An eye status recognition system is implemented for human-machine interactions, and allows drivers to operate in-vehicle systems without contact. This reduces the chances of a traffic accident and enables the development of eye status applications.

Currently in the drastic competitive era for the Machine tool industry, the demand towards multi-function development such as function integration, specialization, high speed, and lightweight has been inevitable trend. That is to say, multifunctional intelligent machine tool is the trend in the future to enhance the product value. The objective of research is to integrate the CAM (Computer Aided Manufacture) function with the human machine interface (HMI) of the machine tool via the development of an intelligent machine HMI that has 2-1/2 axis (2.5D) capability. The Microsoft Windows-Based were adopted as the development platform. The pocket machining function in this research was developed through the contour offset algorithm based on the proposed new adjacent pair-intersection method. The color-filling notion was used to decide if there were removable over-cutting loop firstly; tool path planning was then followed. The representation of sequence tree was applied in tool path planning and independent machining loop was merged by using its hierarchical relations so as to generate the comprehensive tool path. An integrated pocketing loop was defined in this research based on the common G code to ease the programming for the used to create machining cycle. The Unified Modeling Language (UML) was utilized in the development of the HMI system for the system function analysis and planning so as to create the HMI that can satisfy the user’s need. The CAM kernel module was then integrated finally into the HMI to accomplish the intelligent NC machine tool HMI system design and implementation of Cam module. With the developed intelligent NC machine tool HMI system, a user can input directly a general profile containing islands (in DXF format) or the proposed G code-based pocketing program parametrically, and the machining tool path can be immediately displayed and simulated for real machining. The developed methodology has been tested and implemented successfully for reliable application.

Electronic soldering is the most important part of the connector manufacturing process. Because electronic soldering can produce solder joints, which directly leads to product failure, it is important to develop predictive maintenance. In this study, the Drag Soldering station was used as the intelligent target, and the RJ45 connector was used as the soldering object. The machine learning model was constructed by using the parameters of the production, and the sensing system was established to assist the production line personnel to judge whether the product passed. The research is divided into three parts, namely, machine state evaluation and failure literature review, design implementation of software and hardware integration, and analysis of experimental results. First, the soldering process was evaluated, the types of soldering defect were sorted and the priority of the sensor arrangement was evaluated, and the failure of the soldering iron was prioritized. Then use the Queued Message Handler as the software system architecture, and implement the software and hardware modules and integrate them into the host computer interface. The image and temperature signals related to the soldering iron are extracted and pre-processed. Signal feature acquisition, stepper motor control related to soldering platform, solder joint image capture, image analysis, subordinate and external system or function serial connection such as MySQL database module, machine learning model for predicting production status. Finally, the soldering experiment is planned, and multiple classification algorithms are used as the production prediction state, and the regression algorithm is used as the causal relationship confirmation. Taking the production parameters as input, the soldering pass or fail and the defect rate are respectively used as model classification labels. The best classification model is support vector machine, the experimental prediction accuracy is 88.88%, the AUC value is 0.97. The parameters used in the regression model and the yield rate were significant, indicating that the results were not random.

Graphic-Monitor software on market always emphasizes a friendly User-Interface, many types of controllers or devices support, convenient Network-Communication and to communicate with related Database. Nevertheless, I/O control interface cards are not supported by the Graphic-Monitor software. Only Programmable Logic Controllers and Distributed Input/Output modules are supported. In addition, although it provides many basic functions to set devices’ action process, it doesn’t allow user to write complex motion control program. This limits the flexibility of motion control. The solution in the academia is to use various kinds of programming language like C++ Builder or LabVIEW as the development tools. And then, depends on the demand of the hardware to develop Human Machine Interfaces of production devices. Although these programming languages are very powerful, they are too expensive and platform-dependent. In this thesis, a platform independent and cost-free programming language, Java, is adopted to develop a human-machine-interface of an automatic production system integrated with various kinds of I/O control cards. This HMI has the following features: -- Consists of data monitoring, motion control, image inspection, and network communication modules; -- Can run under any operation system; -- Cost-effective. Two integrated examples are implemented with this HMI in the lab. One is ‘Production system remote control’ that combines the motion control and network communication modules; another is ‘Vision introduce search and positioning system’, in which the motion control and image inspection modules are used.

From the viewpoint of disabled persons, this world is full of various barriers that keep them from integrating into society. These barriers range widely from daily movement to daily communications with other persons. Modern technologies can be used to better the lives of those individuals with physical and sensory disabilities. In this regard, the use of appropriate auxiliary equipments can have a major impact on the individual’s continued quality of life and can promote or maintain independent living. Traditional interfaces fall into one of three categories: switches, joystick controllers, and pneumatic devices. Without doubt, present computers affect not just the scientific and engineering community, but society at large. While the positive impact on our life is clear, some disabled persons are suffering from the technology of computers because they cannot share the same benefits of computers as most persons do. For persons with hand dysfunction, it is quite difficult for them to use a mouse and a keyboard to interact with a computer because of the physical restrictions. Therefore, they have fewer chances of getting employment than other persons in today’s society. Apparently, a more friendly human-computer interface should be designed for them. Since speech is a natural communication means for human being, the voice—operation feature is the ideal control method for the large number of disabled people who cannot operate switches. This thesis reports on the design of a voice control human-computer interface for the disabled. Of course, the technology could be adaptive to control other domestic devices or processes. Two different approaches are used to implement the proposed voice control human-computer interface─a hardware-based approach and a software-based approach. Each has its own advantages and disadvantages. In addition, an inexpensive environment control unit incorporated with Bluetooth devices is also developed to permit disabled individuals to control home appliances (such as TV’s, VCR’s, air conditioners, etc). Being able to carry out routine and repetitive tasks in their immediate environment greatly improve the sense of self-reliance of the disabled persons. Otherwise, this continual stream of requests causes an almost unbearable strain on the helpers and the disabled persons themselves.

As manufacture technology advanced to Industrial 4.0, new technologies were rapidly introduced into our life and work environment. Due to the obvious limitations of the traditional hazard and incident analysis, Professor Leveson proposed a Systems-Theoretic Accident Modeling and Processes (STAMP) that focused on the interactions these components and analyzed the possible hazards of automation and mechanics. This study used it to investigate several cases of human-machine interactions, such as the building elevator, the fluid flow experiment unit, the inflow system of wastewater treatment plant (WWTP), and the input system of incinerator. Using STAMP as analytical tool, this study systematically analyzed the possible hazards, limitations, and cause-effect of machine operation. Through the use of system simulation software VENSIM, the cause-effect model could be established and define system hazards. The Systems Theoretic Process Analysis (STPA) was used to identify the hazardous control factors and to find the possible causes of system failures. As those results cross-checked with the cause-effect model, the safety limitations were proposed to reduce the system risks. The elevator system used the lifting speed as the indicator to study the effects of loading changes. The inappropriate operation could cause the rapid up or down as slipping phenomena due to the malfunction of sensors. The fluid flow system used the water-hammer pressure as the indicator to study the effects of water-hammer pressure by the electric ratio valve changing flow rate. The pipe leakages were caused by operational malfunctions due to the in-correct operation of components or the inappropriate parameter settings. The inflow system of WWTP used the pump well levels as the indicator to study the overflow effects druing abrupt storm-flow. Except the inappropriate setting of well level or sensor interferences, the design faults could also induce the system failures. The incinerator system used the chamber temperature as the indicator to study the temperature effects by the garbage moisture contents on the input system. If the temperature monitoring was inappropriated by sensor’s errors or malfunction, the incineration and co-generation efficiency would be lowered. Summarily, STPA showed that all kinds of sensors would play the keys of human-machine interface, control and safety. By cause-effect models and safety limitations, we could effectively reduce all kinds of system risks.

In order to enhance human skill transfer for compliant task execution, in this thesis, we propose an intelligent human- machine interface to integrate robot manipulators with the virtual reality simulation system. The thesis is divided into two parts. In Part I, we propose a human skill transfer scheme for compliant tasks. Difficulties in dealing with compliant tasks mainly result fromtwo reasons. First, it is hard to describe the process of the compliant task execution precisely. Second, even for the same kind of compliant tasks, when theenvironment features vary, it may invoke different interaction between robot manipulators and the environment. Some researchers proposed using the technique of human skill transfer to tackle the problems aforementioned. The current humanskill transfer schemes are still with many deficiencies because the differences are present between the human and the robot manipulators in their mechanisms andcontrol strategies. We then propose a genetic-based fuzzy scheme to improve the ability in human skill acquisition via its learning capability. The proposed scheme is applied to the deburring compliant task for demonstration. In Part II,we develop a human-machine interface for Robot/VR integration. It not only provides a 3D virtual environment for simulations, but can also communicate withthe external robot manipulator. The operator can control the virtual and real manipulators via this robot/VR interface simultaneously. As the proposed interface can provide much information via simulations before experiment execution, it is also useful when applied to CAD (computer aided design) and CAM(computer aided manufacture).

In human-computer interaction (HCI) system, the touch display device is one of the main medium to receive information. There are many small-size touch panel current, so the large-size touch panel is the trend . How to establish a fast and customized touch processor becomes important. We proposed an intelligent classifier which integrates spatial and temporal pattern into discrete event modeling in gesture recognition. We use probabilistic neural network (PNN) as a kernel recognition algorithm, and adding particle swarm optimization (PSO) in the learning phase. As the discrete event modeling is to recognize the continuous-gesture-state transition in the discrete time-slice. To combine these two types of gestures, we use Grafcet discrete event modeling to design the gesture processor instruction set architecture. User can use it to enerate a variety of customized HCI interface gestures processor quickly. With this gesture processor instruction set architecture, we can define customized gesture recognition processor such as medical bedside care system and IPTV. This intelligent classifier provides an excellent recognition performance, high flexibility and rapid prototype gesture recognition in human-machine interaction application .

In the field of smart manufacturing, the conventional human–machine interface (HMI) is characterized by long development duration, high maintenance cost, poor adaptability to new requirements, and limited user freedom. Therefore, this study endeavored to develop a graphical user interface (containing a flexible, embedded structure) with intuitive control features and a simple and clear setup function based on user experience. The system comprises five functional modules： add new component, component control, data transfer, data reception, and component update. The interface relies on the data transfer and reception modules to communicate with extrinsic devices and the interactions between modules for smart human–machine interaction. By contrast, the conventional HMI, which has no real-time HMI customization functions, has to rely on specialized industrial graphics control software that must be operated on a personal computer to faciliate HMI software development and updates; this makes immediate HMI software development and updates impossible. Because of the flexible design of the proposed system, new functions and updates can be readily developed and deployed through the system’s HMI. This effectively keeps the HMI up-to-date, gives the HMI higher adaptability, considerably shortens the duration of HMI development, and increases the ease with which outdated control software for automated equipment can be updated or replaced.

This thesis presented a Human Machine Interface (HMI) of lead-acid battery charger for photovoltaic power system. Because the solar energy power was affected by environment and we had to prevent an overcharge of lead-acid battery, we had to design a charging system including HMI to monitor the charging current and charging voltage of lead-acid battery. In this thesis, we designed the program graphically by using LabVIEW software. The software is combined with Data Acquisition (DAQ) which can present available I/O channels and operate the project items. By using HMI, we can monitor the state of charging at all time. The duty-cycle is determined by the lead-acid battery temperature, charging current and terminal potential.

In this research, the purpose is to establish human machine interface (HMI) that we program and apply it in the real time monitoring of laser machine. The reason is that laser industry is developing fast, and economic benefit from it grows amazingly. However, the development of laser industry in domestic is limited to some conditions and need to improve it. Therefore, this research focuses on the design of intelligent human machine interface of laser machine. We conduct PLC and power system integration by human machine interface to execute safety protection and real-time monitoring in laser machine. In the meantime, an automatic laser machine has its own intelligent human machine interface, and expect this HMI capacity can promote domestic development in laser industry. This research is to use human machine interface to execute PLC and power system integration, and also to monitor its controlled contents and message. The human machine interface is written in PC based program. This program includes multifunctional modules, e.g. real-time data monitoring, environment monitoring, motion monitoring, network communication, laser safety, system security protection setting, etc. This intelligent human machine interface is convenient for user to operate machine. If it happens mechanical failure or other accident, it is easier to execute system recovery and equipment maintenance. The experimental results prove that this program can execute these tasks, such as monitoring and machine operating. When it is not permitted to produce in the environment of laser machining, or it occurs hazardous accident, it also executes protective measures automatically to let machine go off. Even though the machine is powered off, the system can execute lock compulsorily to protect machine until the crisis is lifted. The human machine interface is not only the host computer but also has real-time monitoring and control capacity. Therefore, it is suitable for applying in automatic machine factory.

The advance of technology brings us into a new era of industrial revolution. To stay ahead of competition in this global economy, companies around the world need to quickly create new and distinguishing features to increase attractiveness and competiveness except using the traditional methods to reduce the cost and improve the quality of their products. The main objective of this study is to develop a professional human machine interface (HMI) for a cutting machine with a four-axis CNC controller module. This is a PC-based platform with the open architecture. Therefore, one can develop an intuitive HMI and flexible PLC sequential control to construct the automatic system for a cutting machine. Furthermore, this will strengthen the competitive ability for the cutting machine industry in Taiwan. This thesis uses the C++ Builder software to design the HMI for a cutting machine. The planning of the HMI and functions is based on the operator’s point of view and experience. With the help of the cutting machine manufacturer’s expertise, the automatic and intelligent functions of the HMI are developed. Finally, this study repeated the tests of the whole system functions to verify the correctness of the system.
