Résumé :

Advances in mobile computing and wireless communication are easing the evolution from traditional nomadic work to computer-mediated mobile collaborative work. Technology allows efficient and effective interaction among mobile users and also provides access to shared resources available to them. However, the features and capabilities of the communication infrastructure supporting these activities influence the type of coordination and collaboration employed by mobile collaborative applications in real work scenarios. Developers of these applications are typically unaware of the constraints the communication infrastructure imposes on mobile collaborative systems, because they are not easy to foresee. That leads to a high probability of communication problems in otherwise fully functional mobile collaborative support applications. This paper presents an experimental study with real devices and networks on a realistic physical environment that shows how ad hoc networks can effectively support mobile collaborative work and the practical limitations. The paper analyzes several networking issues and determines how they influence mobile collaborative work in various interaction scenarios. The paper also presents the lessons learned in the study and provides recommendations to deal with some networking issues related to real-world ad hoc networks.

Résumé :

Abstract As the range of handheld, mobile and desktop devices expands and worldwide demand for collaborative application tools increases, there is a growing need for higher speed impromptu cross-device application sharing to keep up with workplace requirements for on-site or remote collaborations. To address this, we have developed CamCutter, a cross-device interaction technique enabling a user to quickly select and share an application running on another screen using the camera of a handheld device. This technique can accurately identify the targeted application on a display using our adapted computer vision algorithm, system architecture and software implementation, allowing impromptu real-time and synchronized application sharing between devices. For desktop and meeting room set-ups, we performed a technical evaluation, measuring accuracy and speed of migration. For a single-user reading task and a collaborative composition task, we carried out a user study comparing our technique with commercial screen sharing applications. The results of this study showed both higher performance and preference for our system. Finally, we discuss CamCutter’s limitations and present insights for future vision-based cross-device application sharing.

Résumé :

Developing writing skills in a foreign language is one of the demanding tasks for both teachers and students. It not only demands extensive reading and intensive practice in writing both inside and outside the classroom but also timely feedback and error-correction. The experimental study aimed at studying the impact of collaborative writing tasks using mobile applications like WhatsApp, Google Docs, and Google Slides on enhancing the writing ability at the pre-intermediate level of Common European Frame of Reference (CEFR). The participants were tertiary level students of Cihan University who were randomly divided into two equal groups (n=28). One group used WhatsApp and the other group used the Google Docs and Google Slides apps on their mobile devices. The comparative study analyzed the impact of each application on improving the writing skills of the students with pretest and posttest results and semi-structured interviews. The results indicated that the participants who used Google Docs and Google Slides apps have performed better than the participants in the WhatsApp group. The results have implications for teachers teaching writing skills and students who write using mobile applications.

Résumé :

Context information consumed and produced by the applications on mobile devices needs to be represented, disseminated, processed and consumed by numerous components in a context-aware system. Significant amounts of context consumption, production and processing takes place on mobile devices and there is limited or no support for collaborative modelling, persistence and processing between device-Cloud ecosystems. In this paper we propose an environment for context processing in a Cloud-based distributed infrastructure that offloads complex context processing from the applications on mobile devices. An experimental analysis of complexity based context-processing categories has been carried out to establish the processing-load boundary. The results demonstrate that the proposed collaborative infrastructure provides significant performance and energy conservation benefits for mobile devices and applications.

Résumé :

Mobile crowdsensing is an emerging technology in which participants contribute sensor readings for different sensing applications. This technology enables a broad range of sensing applications by utilizing smartphones and tablets worldwide to improve people’s quality of life. Protecting participants’ privacy and ensuring the trustworthiness of the sensor readings are conflicting objectives and key challenges in this field. Privacy issues arise from the disclosure of the participant-related context information, such as participants’ location. Trustworthiness issues arise from the open nature of sensing system because anyone can contribute data. This article proposes a privacy-preserving collaborative reputation system that preserves privacy and ensures data trustworthiness of the sensor readings for mobile crowdsensing applications. The proposed work also counters a number of possible attacks that might occur in mobile crowdsensing applications. We provide a detailed security analysis to prove the effectiveness of privacy-preserving collaborative reputation system against a number of attacks. We conduct an extensive simulation to investigate the performance of our schema. The obtained results show that the proposed schema is practical; it succeeds in identifying malicious users in most scenarios. In addition, it tolerates a large number of colluding adversaries even if their number surpass 65%. Moreover, it detects on-off attackers even if they report trusted data with high probability (0.8).

Résumé :

Cassava-chip is considered one of Thailand’s most important economic crops and Thailand is the world’s largest cassava products exporter. Thai government is prioritizing the cassava production in their “Mega farm” strategy in support of agricultural economic and collaboration between farmer, public and private sectors. The collaborative model is an integrated supply chain that manages the multiple stakeholders. Moreover, implementing the collaborative supply chain (CSC) has improve overall performance of the entire supply chain. The study aims to review existing literature on collaborative model and critical success factors in the agriculture supply chain context during 2008-2018 and the 20-year agriculture and cooperatives strategy (2017-2036). The six key collaborative success factors are identified: Business Management, Information Technology, Value Added Process, SC Relationship, Top Management Commitment, Partnership, Service Quality, Process, Resource Capability, Environment Uncertainties, Customer Satisfaction. The hypothesis will be tested by the linear regression analysis and develop the prototype of CSC mobile application to create the collaboration in cassava chip industry. Then, the result will be embedded into mobile application. The application will later be used to provide more appropriate third-party system to enhance the collaborative cassava chip supply chain in Thailand. The result shows that all components are supported by the hypothesis and user acceptance test.

Résumé :

Nations are making huge investments to ensure that their citizens receive the education so that they can contribute to different aspects of development of a country. Despite the investments in education in many countries, researches show that there is need to improve the quality of education offered in tertiary institutions. To improve the quality of education offered institution of higher learning need to consider approaches that place students at the center of the learning process. One such approach is to use mobile application-aided collaborative learning. Mobile application-aided Collaborative learning promises great benefits to students and institutions. However, to successfully implement mobile application aided collaborative learning, it is important to determine if students are ready to use it. In this paper, we use the Unified Theory of Acceptance and Use of Technology (UTAUT) to determine the key factors that should be put in place for collaborative learning to be used successfully. The main contribution that this paper makes is that, it identifies the factors that Copperbelt University needs to work on so that collaborative learning can be used more effectively.

Résumé :

This paper proposes a zonation method for training the two reinforcement learning agents. We demonstrate the method's effectiveness in the double snake game. The game consists of two snakes operating in a fully cooperative setting to maximize the score. The problem in this game can be related to real-world problems, namely, coordination in autonomous driving cars and the operation of collaborative mobile robots in warehouse applications. Here, we use a deep Q-network algorithm to train the two agents to play the double snake game collaboratively through a decentralized approach, where distinct state and reward functions are assigned to each agent. To improve training efficiency, we utilize the snake sensory data of the surrounding objects as the input state to reduce the neural network complexity. The obtained result show that the proposed approaches can be used to train collaborative multi-agent efficiently, especially in the limited computing resources and training time environment

Résumé :

The travel and tourism industry is one of the main sources of income in Thailand. People choose to travel around the world, as a way to relax and enjoy their time. Users search information from many resources before and during their travel. We grouped the mobile tourism applications into two main groups in order to analyse the nature of information in the tourism applications. Social network provides rich collaborative user-generated information. We found that most tourism applications require personal information and pre-existing association in order to get information. We argue that, in tourism, a user requires instant and easy access to information. So the social network might not be an appropriate option. Therefore we propose a simple collaborative user-generated content application, which has a location awareness chat system. We aim to provide an application with self-sufficient information that allows the user to instantly share, search, and comment on information at anytime and anywhere. Moreover, the location awareness chat system is introduced to provide instant firsthand information to the users as well.

Résumé :

Purpose Free-riding behaviour may threaten the success of teamwork, when one or more group members receive the benefits of other members’ achievements with little effort or cost of their own. The purpose of this paper is to investigate students’ collaborative behaviour to address the problem of free riders (FRs) in university settings. Design/methodology/approach The research is an 11-week field study of three senior finance classes and incorporates mobile learning employing Quip and Google Docs applications to facilitate group work. A comprehensive set of quantitative and qualitative methods analysing students’ perceptions, instructors’ reflections, peer reflections and mobile learning methods are used to answer questions pertaining to group work, the work experience, FRs and ways to minimise the last. Findings In this paper, the author shows that students at the university level have positive views of group work despite the presence of FRs. Students like to form their own groups; consequently, peer evaluation appears to be unreliable. The study points to free riding as a serious threat to academic productivity and calls for actions and strategies from institutions and instructors to eradicate this behaviour. Mobile applications enable instructors to track FRs and to some extent discourage their behaviour. Originality/value There are limited studies that focus on FRs in higher education and, to the researcher’s knowledge, no such investigation has been applied in the Middle East and North Africa. Likewise, there is little research available on incorporating mobile learning to assess group work in higher education. This study aims at exploring the existence and associated experiences of free riding, along with methods to curtail the problem. The findings of this study provide a good platform for inquiry into the FR phenomenon in higher education and its impact on student learning, as well as the possible roles of instructors and mobile applications. The findings of this study could be developed further through more research with a view to providing a broader perspective of the situation in Middle Eastern and North African cultures.

Résumé :

The resourceful mobile devices with augmented capabilities around human pave the way for utilizing it as delegators for resource-constrained devices to run compute-intensive applications. Such collaborative resource sharing policy among mobile devices throws challenges like identifying competent alternatives for offloading and diminishing time consumption of pre-offload process to accomplish remarkable offloading. This paper presents a Mobile Cloud Computing framework with Predictive Context-Aware Collaborative Offloading Process (PCA-COP) that fixes these challenges through conductive alternative discovery. This context-aware discovery adapts a multi-criteria decision making model of Analytic Hierarchy Process (AHP) accompanied with Fuzzy categorization to rank the alternatives and classify them into Highly, Fairly, Less offload-suitable devices. Moreover, to make alternative selection optimal, a Dataset Curtailment enabled Artificial Neural Network (DCANN) prediction is incorporated on AHP-Fuzzy model, which truncates training dataset using Conditioned Stratified Sampling (CSS). The prototype framework is evaluated with mobile applications in the classroom under dynamic context environments.

Résumé :

The development of leading-edge multimodal (e.g., concurrent text, voice, and video capabilities) mobile applications as a technology that holds promise for the construction industry is described. Because of the complexity of the products, the relatively short execution time frame, and the number of parties involved, the information exchanged throughout an architectural, engineering, and construction (AEC) project is extensive. Efficiently managing this information exchange is a significant impediment to increasing the overall productivity of the industry. The technology focus of this paper extends today's tools by addressing one of the unique characteristics of the industry: the need for mobility of real-time information in an integrated and collaborative environment. Mobile computing devices have the capabilities and characteristics for wide use in real-time communication of project information to project repositories or between project participants. As the industry moves away from the desktop and laptop Web paradigms toward the mobile Web paradigm, the availability of real-time complete information exchange with the project information repository presents new opportunities for decision-making in the AEC industry. To facilitate more widespread use of the solution applications described, extensive usability research in light of the various processes in the AEC industry is needed; a preliminary framework for this purpose is presented.Key words: project information management, collaborative information systems, mobile computing, multimodal functionality.

Résumé :

Computation offloading and caching strategy is a well-established concept for allowing mobile applications that are high in resources. Furthermore, the unloaded duties can be replicated when several customers are within easy access because of the rising mobile cooperation applications. However, the problematic characteristics of offloading and caching strategy delay bandwidth transfer from mobile computing devices to cloud computing. A new technical approach to restrict the issues and unwanted functions in offloading and caching is called the intellectual power computing framework (IPCF). IPCF depends on two conventional offloading and caching strategies called systematic offloading technique and managerial migrant caching. The migration of data transfer from the destination to location basis lies in the systematic offloading technique to restrict network delays. Managerial migrant caching duplicates the data required by the mobile terminals (MTs) from the remote cloud storage to the mobile application to reduce the access time. The forbidden actions in current techniques are refused, and solutions are enhanced for better communication strategy. Thus, the simulation analysis performs better in IPCF to reach efficient outcomes for offloading and caching processes.

Résumé :

Vocabulary teaching and learning constitute a major problem for EFL instructors and students. EFL freshman students have difficulty in pronouncing, recognizing the meaning of, using and spelling new English words. Due to the Covid-19 Pandemic, all college courses have shifted to online distance learning since March 2020. Surveys with samples of college students and instructors in Saudi Arabia showed lack of interest among the students in online instruction, participation, giving oral presentations, doing homework-assignments, attending online classes, low engagement, interaction, communication and self-efficacy. No adaptations have been made in the college curricula. Since the new distance learning environment requires new modes of teaching and learning, the present study proposes a variety of online vocabulary tasks and technologies that vocabulary instructors can choose from, such as mobile-based applications viz Vocup, Quizlet, Quizizz, game-based mobile apps, Saving Alice, Duolingo, Kahoot, vocabulary flashcards, mobile audiobooks, collaborative mobile ebook reading; podcasts; online dictionaries; concordance-based glosses; picture viewing and picture drawing on tablets; videos; e-portfolios; teaching idioms via graphic novels; multimedia annotations; social networks; project-based learning and mind-maps. To engage, motivate and encourage student-student and student-instructor interaction in the distance learning environment, the study proposes the following: using WhatsApp, ConnectYard, creating a community of inquiry, creating learning partnership, collaborative writing exchange projects, student collaboration, social interaction, integrating text-chat and webcam, and utilizing technology-mediated task-based language teaching. Online vocabulary tasks can be performed individually, in pairs or in small groups; interactively or collaboratively; synchronously or asynchronously. Instructional phases and teacher and students’ roles are also described.

GeoPackage is a data format that open-standard, platform-independent, portable, and self-describing. This paper focus on the implementation of GeoPackage in mobile application for field data collection. A mobile application was developed that implements the GeoPackage data format as an internal database to provide support for offline mapping. The developed mobile application demonstrates that vector and raster data can be stored in a single data format, which reduces the device storage consumption. The details of how GeoPackage data contribute to mobile GIS to achieve collaborative mapping in limited network environments are discussed. The findings show that the GeoPackage data format has great potential to improve existing mobile GIS applications.

Résumé :

Perception capability assumes significant importance for human–robot interaction. The forthcoming industrial environments will require a high level of automation to be flexible and adaptive enough to comply with the increasingly faster and low-cost market demands. Autonomous and collaborative robots able to adapt to varying and dynamic conditions of the environment, including the presence of human beings, will have an ever-greater role in this context. However, if the robot is not aware of the human position and intention, a shared workspace between robots and humans may decrease productivity and lead to human safety issues. This paper presents a survey on sensory equipment useful for human detection and action recognition in industrial environments. An overview of different sensors and perception techniques is presented. Various types of robotic systems commonly used in industry, such as fixed-base manipulators, collaborative robots, mobile robots and mobile manipulators, are considered, analyzing the most useful sensors and methods to perceive and react to the presence of human operators in industrial cooperative and collaborative applications. The paper also introduces two proofs of concept, developed by the authors for future collaborative robotic applications that benefit from enhanced capabilities of human perception and interaction. The first one concerns fixed-base collaborative robots, and proposes a solution for human safety in tasks requiring human collision avoidance or moving obstacles detection. The second one proposes a collaborative behavior implementable upon autonomous mobile robots, pursuing assigned tasks within an industrial space shared with human operators.

Résumé :

The development of mobile technology has an important role to play in achieving 21st-century skills. Collaborative skills and problem-solving are seen as fundamental skills for achieving 21st-century skills as a whole. This study aims to develop collaborative problem-solving based on mobile multimedia (CPMM) to achieve student collaborative and problem-solving skills. Multimedia development life cycle (MDLC) is used as a research method to develop CPMM. The CPMM was developed by involving 100 students at the Universitas Muhammadiyah Surabaya, Indonesia. The CPMM development result consisted of three main features. The first feature was the homepage which was used to show student profiles and progress in the course. The second feature was collaborative to become a forum for students to discuss and interact in multi-way mobile ways to solve problems. The third feature was evaluation as tasks from a lecturer to individual students to solve problems. In addition, the study results showed that CPMM was valid and effective for improving students' collaborative and problem-solving skills. This study recommends that CPMM can be used as an essential study and the basis for lecturers and practitioners to develop 21st-century student skills as a whole (not only collaborative and problem-solving skills) to produce graduates who are ready to face the revolutionary era 4.0.

Résumé :

The fast growing popularity of smartphones and tablets enables us to use various intelligent mobile applications. As many of those applications require position information, smart mobile devices provide positioning methods such as Global Positioning System (GPS), WiFi-based positioning system (WPS), or Cell-ID-based positioning service. However, those positioning methods have different characteristics of energy-efficiency, accuracy, and service availability. In this paper, we present an Energy-Efficient Collaborative and Opportunistic Positioning System (ECOPS) for heterogeneous mobile devices. ECOPS facilitates a collaborative environment where many mobile devices can opportunistically receive position information over energy-efficient and prevalent WiFi, broadcasted from a few other devices in the communication range. The position-broadcasting devices in ECOPS have sufficient battery power and up-to-date location information obtained from accurate but energy-inefficient GPS. A position receiver in ECOPS estimates its location using a combination of methods including received signal strength indicators and 2D trilateration. Our field experiments show that ECOPS significantly reduces the total energy consumption of devices while achieving an acceptable level of location accuracy. ECOPS can be especially useful for unique resource scarce, infrastructureless, and mission critical scenarios such as battlefields, border patrol, mountaineering expeditions, and disaster area assistance.

Résumé :

This paper focuses on the distributed architecture of the collaborative threedimensional user interface management system, Studierstube. The system allows multiple users to experience a shared 3D workspace populated by multiple applications using see-through head-mounted displays or other presentation media such as projection systems. Building large, ubiquitous, or mobile workspaces requires distribution of applications over several hosts in varying and dynamic configurations. The system design is based on a distributed shared scene graph that alleviates the application programmer from explicitly considering distribution and that avoids a separation of graphical and application data. The idea of unifying all system data in the scene graph is taken to its logical consequence by implementing application instances as nodes in the scene graph. Through the distributed shared scene graph mechanism, consistency of scene graph replicas and the contained application nodes is assured. Dynamic configuration management is based on application migration between participating hosts and a spatial model of locales allowing dynamic workgroup management. We describe a number of experimental workspaces that demonstrate the use of these configuration management techniques.

Résumé :

The ubiquitous use of smartphones has shown to offer great advantages in language learning, which still remain to be harnessed in the field of mobile-assisted language learning (MALL), ESP teaching and translator training in higher education. Language teachers are predominantly the users of existing mobile applications and not their producers, which may narrow their range of choices and options in using mobile technology in teaching. This paper presents the results of a student survey on the usability, perceived benefits, and feedback on the features of an Android mobile application built by the author. The CoLecTer KIN application was used by first-year undergraduate students of Applied Kinesiology in a collaborative project of compiling a Slovene-English bilingual glossary of topic-specific terminology. The design of the application makes it suitable for use in the ESP and translation classroom and in collaborative translation projects.

Résumé :

Purpose The purpose of this study is to examine mobile technology as being a key apparatus and interface for collaborative innovation, which allows organisations to develop their information ecology. Design/methodology/approach The qualitative research was performed by in-depth interviews, observations and field notes. The eight main interviews are supported by an interdisciplinary narrative literature review of knowledge management and associated fields. Findings This study validates the following propositions: mobile technology can offer users timely information, mobile technology can foster collaboration beyond physical and organisational boundaries, in general, mobile technology enables a wider amount of interactions between people. Thereby, this paper draws some implications about the knowledge management of creative (and non-creative) workers. Research limitations/implications The collected data sheds light on how organisations and individuals positioned themselves about mobile technology co-creative practices before the COVID era. Therefore, it shall be pertinent to further investigate these findings through a quantitative approach to better ascertain path models and to strengthen the new results with another qualitative perspective, in the post-COVID era. Practical implications The study highlights how mobile devices are facilitating collaborative innovation practices by improving management decisions, enabling new business and/or operating models, developing a flow of ideas inner/outer an organisation and fostering the ability to make innovation. Social implications Mobile technology transforms the way to work (knowledge creation and/or conversion) and it changes the relations between collaborators in a working environment (beyond physical boundaries). This study deciphers how a creative and/or decision-making person can change their work schedule and/or routines based on the use of mobile devices. Originality/value The added value of this transdisciplinary study is that it improves research on collaborative innovation and collective knowledge by revealing three pertinent characteristics of mobile technology: enabling quick decision; connecting with a glocal network and fostering collective creativity. It also creates a bridge between the fields of education and business.
