Texto completoFor almost three decades GPS coordinates and directions have been displayed with a top-down 2D view. At first in dedicated navigation systems, commercially used for driving, into today having GPS systems available in our everyday smartphones. The most common way to display the coordinates today are still by some sort of 2D view showing the user where it is and what roads/streets to take. This however has some problems that we believe can be solved using Augmented Reality combined with GPS. This paper sets out to answer the question if and how Augmented Reality displayed navigation can make it easier for pedestrians to navigate through a city compared to a 2D displayed navigation. In order to answer the question at hand this study presents a navigation application that combines the two technologies GPS and Augmented Reality which then is used in a user test. The results from the user tests and the questionnaire indicates that Augmented Reality based navigation is best used in scenarios where there are a lot of streets and it is hard to tell on a 2D map which street to take.

As a result of advances in computer vision, mapping, and controls, wearable technology for visually-impaired individuals has become a growing space of research within Assistive Technology. A team at the MIT Energy Ecient Circuits Group has made an important stride forward by presenting a wearable navigation prototype in a fully integrated hardware form factor, but one of biggest barriers to usability of the device is its excessive power consumption. As such, the goal of this work is, broadly, to- (1) Understand the largest sources of power consumption in the initial navigation proto- type system, and expose relevant features for control; (2) Develop a set of algorithms that can capitalize on the motion of a user, the motion of the environment around a user, and the proximity of obstacles within the environment to the user, in order to dynamically tune the exposed parameters to scale power as necessary; and (3) Lay the foundation for the next generation wearable navigation prototype by translating critical software operations and the power scaling algorithms into a hardware architecture capable of working with a smaller and less power intensive depth camera. The first portion of this work focuses on the wearable navigation prototype built around Texas Instrument's OPT9220/9221 Time of Flight chipset. Illumination voltage, frame rate, and integration duty cycle are identied as key control features, and a step rate estimation algorithm, scene statistics algorithm, and frame skipping controller to tune these features are built and tested. The latter half the work focuses on the newer OPT8320 evaluation platform, for which a Bluespec System Verilog implementation of these power algorithms and the point cloud generation operation is presented and tested. Overall, the work demonstrates the critical concept that simple, system specific, fully integrated algorithms can effectively be used to reduce analog power system-wide.

Texto completoIndoor navigation could be used in many applications to enhance performance in
its specific area. Anything from serious life critical tasks like aiding firefighters or
coordinating military attacks to more simple every day use like finding a desired
shop in a large supermarket could be considered. Smartphones of today introduce
an interesting platform with capabilities like existing, more clumsy, indoor
navigation systems. The iPhone 3GS is a powerful smartphone that lets the programmer
use its hardware in an efficient and easy way. The iPhone 3GS has a
3-axis accelerometer, a 3-axis magnetometer and hardware accelerated image rendering
which is used in this thesis to track the user on an indoor map. A particle
filter is used to track the position of the user. The implementation shows how
many particles the iPhone will be able to handle and update in real time without
lag in the application.

Texto completoIn this study we compare two different navigation menus in the context of a news application. We develop two prototype application implementing two different navigation menus. User-tests are used to measure how effectively a user can perform a set of specified tasks. An exploratory study is performed where already existing news applications are studied. We analyze which navigation menus are actually used in popular news applications. Our study shows there are really only two options, namely what we choose to call a top-menu, and a drawer menu. The results from our tests shows that the difference in usability is not so big between the two menus. Although we do find some strengths and weaknesses in both navigation menus. The “top menu” results in a greater amount of clicks and errors, but the test is completed a bit faster compared to the drawer menu. The persons doing the tests on the top- menu seems more satisfied compared to those doing the same tests with the drawer menu. We notice that the drawer menu can be a bit difficult to use if the user is not accustomed to it. However, it can be used very effectively if the user knows how to use it correctly. The conclusion of this study is that the differences are quite small between the two navigation menus, but overall the users seem to be more satisfied with a top menu in the given context. However, there are advantages with using a drawer menu which shows that it is a very usable navigation menu if the application has a “broad” navigation structure.

Texto completoThis research deals with the analysis of the evidence of maritime means of transports in use in the Western Mediterranean sea between the birth of the human navigation and the First Iron Age. Starting from a general revision of the local naval iconography of the period, based on a reassessment of the evidence coming from many archaeological sites placed between the Adriatic Sea and the Southern Spanish coasts, the study shed a light the existence of many different regional traditions that date back at least from the Bronze Age. The possibility to identify these traditions, as well as to examine them from a diachronic point of view, allows the author to state that we cannot think about an introduction from the east of the concept of maritime navigation. During the prehistory, particularly from the Bronze Age, the local cultural groups of this area seem in fact to have already developed good naval attitudes and capabilities. Even the analysis of the local iconography in the light of the technological elements that we can isolate on the Mediterranean wrecks of this period seems to confirm the existence of these local traditions. Unfortunately, the lack of a good number of direct evidence pertaining to wrecks do not permit us investigating these technological traditions. Thus, we cannot not identify the architectural families of the earliest phases; we can have an idea of their existence only in correspondence with the presence of Greeks and Phoenicians merchants and ships

Texto completoNavigering kan innebära en stor utmaning för personer som lider av en demenssjukdom, även i för dem bekanta miljöer. Företag runtom i världen utvecklar idag assisterande hjälpmedel för denna målgrupp. Men att ta hjälp av och bli bekväm med att använda den här typen av teknologier kan fortfarande upplevas som problematiskt, då personer med demens vanligen kan uppleva ny teknologi som svår att använda. Bland dessa nya teknologier finns dock en teknologi som har skrivits om som både intuitiv och lätt att ta till sig, nämligen Augmented Reality (AR). Därför ämnar denna studie att undersöka hur denna specifika teknologi skulle kunna implementeras, med andra ord, hur ett AR-gränssnitt skulle kunna designas för en mobilnavigeringsapplikation så att personer med mild demens kan använda den självständigt. Denna kvalitativa studie baseras på en pilotstudie följt av två användbarhetstester, där personer som diagnostiserats med mild demens fått testa en navigeringsapplikation och en navigationsmockup för smartphone. Båda implementerar AR-teknik men med två olika gränssnittsdesigner: i) en som innehåller en animerad figur och ii) en som använder pilar samt ett filter som kan sättas på och av. Fem personer deltog i varje användbarhetstest. Den insamlade datan från intervjuerna och observationerna analyserades sedan med hjälp av en fenomenologisk–hermeneutisk metod. Överlag så tyckte deltagarna att AR-tekniken var användbar vid navigeringen. Resultatet visade också att respondenterna var relativt neutrala till vilken av AR-gränssnitten som användes. Majoriteten uttryckte att det var enklare att navigera med navigationsmockupen när filtret var av. Slutligen så presenterar denna studie fem designimplikationsförslag att ha med sig vid utvecklandet av den här typen av assisterande tekniska hjälpmedel för personer med mild demens. AR-gränssnittet bör: använda en ofiltrerad kameravy, vara intuitivt, vara anpassat till utomhusmiljöer, inte hindra användaren från att fokusera på omgivningen, vara precist och trovärdigt.

Texto completoThe field of research connected to mobile robot navigation is much broader than the scope of this thesis. Hence in this report, the navigation topic is narrowed down to primarily concerning mapping and scan matching techniques that were used to achieve the overall task of navigation nature. Where the work presented within this report is based on an existing robot platform with technique for providing 3D point-clouds, as result of 3D scanning, and functionality for planning for and following a path. In this thesis it is presented how a scan matching algorithm is used for securing the alignment between provided succession point-clouds. Since the computational time of nearest neighbour search is a commonly discussed aspect of scan matching, suggestions about techniques for decreasing the computational time are also presented within this report. With secured alignment, the challenge was within representing provided point-clouds by a map model. Provided point-clouds were of 3D character, thus a mapping technique is presented that provides rough 3D representations of the environment. A problem that arose with a 3D map representation was that given functionality for path planning required a 2D representation. This is addressed by translating the 3D map at a specific height level into a 2D map usable for path planning, where this report suggest a novel traversability analysis approach with the use of a tree structure.

Texto completoDet här examensarbetet presenterar ett ramverk för självlärande säkerhetskritiskareglersystem. Ramverket är baserat på en kombination av adaptivmodellinärning och barriär-certifikat, och kan hantera system med ickestationärdynamik. För att extrahera den dynamiska strukturen hos modellenanvänder vi en gles optimeringsteknik och den resulterande modellenanvänds sedan i kombination med barriär-certifikat som endast begränsarden återkopplade styrlagen när systemsäkerheten är i fara. Under milda antagandenvisar vi att optimeringsproblemet som måste lösas för att hittaden optimala styråtgärden i varje tidpunkt är konvext, och att prestandanhos den inlärda styrlagen förbättras monotont. Dessutom omformulerar vivärdefunktions-approximationsproblemet så att det kan lösas med en godtyckligmetod för kärnbaserad funktionsskattning. Vi använder sedan enledande teknik för kärnbaserad adaptiv filtrering för värdefunktionsapproximationeni vår algoritm. Det resulterande ramverket verifieras slutligenexperimentellt på en borst-robot, vars dynamik är okänd och mycket komplex.

Texto completoOne of Saab Space’s products is the S19 guidance system for sounding rockets.Today this system is based on an inertial navigation system that blindly calculatesthe position of the rocket by integrating sensor readings with unknown bias. Thepurpose of this thesis is to integrate a Global Positioning System (GPS) receiverinto the guidance system to increase precision and robustness. There are mainlytwo problems involved in this integration. One is to integrate the GPS with sensorfusion into the existing guidance system. The seconds is to get the GPS satellitetracking to work under extremely high dynamics. The first of the two problems issolved by using an Extended Kalman filter (EKF) with two different linearizations.One of them is uses Euler angles and the other is done with quaternions. Theintegration technique implemented in this thesis is a loose integration between theGPS receiver and the inertial navigation system. The main task of the EKF isto estimate the bias of the inertial navigation system sensors and correct it toeliminate drift in the position. The solution is verified by computing the positionof a car using a GPS and an inertial measurement unit. Different solutions to theGPS tracking problem are proposed in a pre-study.
En av Saab Space produkter är navigationssystemet S19 som styr sondraketer.Fram till idag har systemet varit baserat på ett tröghetsnavigeringssystem somblint räknar ut position genom att integrera tröghetsnavigerinssystemets sensorermed okända biaser. Syftet med detta exjobb är att integrera en GPS med tröghetsnavigeringsystemetför att öka robusthet och precision. Det kan i huvudsak delasupp i två problem; att integrera en GPS-mottagare med det befintliga navigationsystemetmed användning utav sensorfusion, och att få satellitföljningen attfungera under extremt höga dynamiska förhållanden. Det första av de två problemenlöses genom ett Extended Kalman filter (EKF) med två olika linjäriseringar.Den första linjäriseringen är med Eulervinklar och är välbeprövad. Den andra ärmed kvaternioner. Integrationstekniken som implementeras i detta Examensarbeteär en lös integration mellan GPS-mottagaren och tröghetsnavigeringssystemet. Huvudsyftetmed EKF:en är att estimera bias i tröghetsnavigeringsystemets sensoreroch korrigera dem för att eliminera drifter i position. Lösningen verifieras genomatt räkna ut positionen för en bil med GPS och en inertiell mätenhet. Olika lösningartill satellitföljningen föreslås i en förstudie.

Texto completoIn spite of all electronic navigation devices on a modern ship bridge, navigators still lose their orientation. Reasons for this might be excessive cognitive workload caused by too many instruments to read and compile, navigation information that is displayed in a cognitively demanding way, short decision times due to high speed or fatigue due to minimum manning and long work hours.
This work addresses the problem of map information displayed in a less than optimal way. Three new concepts are presented: the bridge perspective, the NoGO area polygons and a dual lane seaway network. Map reading can be difficult due to the problem of mental rotations. By allowing a 3-D nautical chart to be viewed from an egocentric bridge perspective, the need for mental rotations can be removed. The cognitively demanding calculations necessary to find out if there is enough water under the keel can be made by the chart system and the result displayed as of free water and NoGo areas. On land car driving is facilitated by a road-network and a sign system. This notion can be further developed on sea and make navigation easier and safer.
These concepts were then tested in a laboratory experiment, in interviews and in a prototyping project. The results were very promising. The experiment in a laboratory maze showed that map reading from an egocentric perspective was more efficient than using traditional paper and electronic maps. Interviews and expert evaluation of prototypes also showed great interest from practitioners in the field.
Trots all elektronisk utrustning på en modern skeppsbrygga händer det att navigatörerna förlorar orienteringen. Anledningen kan vara hög kognitiv belastning därför att för många olika instrument måste avläsas och integreras samtidigt, att informationen på instrumenten behöver tolkas på ett kognitivt krävande sätt, att tiden för att fatta beslut blir allt kortare på grund av högre hastigheter till sjöss eller på grund av trötthet.
I detta arbete presenteras tre nya koncept för visualisering av navigationsinformation: bryggperspektivet, djupvarningspolygoner och sjövägar.
Kartläsning kan ibland vara svårt på grund av de mentala rotationer en användare tvingas genomföra för att kunna jämföra kartan med verkligheten. Genom att göra det möjligt för en användare att se sjökortet ur ett egocentriskt bryggperspektiv, så onödiggörs dessa mentala rotationer. De kognitivt krävande beräkningar som navigatören behöver göra för att försäkra sig om att det finns tillräckligt med vatten under kölen, kan utföras av kartsystemet och resultatet visas istället som fria vattenytor och djupvarningsområden (NoGo areas). På land underlättas bilkörning av ett vägnät med körbanor, filer och skyltar. Detta system kan i högre utsträckning införas till sjöss för att underlätta säker navigering.
Dessa koncept har sedan testats genom ett laboratorieexperiment, genom intervjuer och i ett prototyputvecklingsprojekt. Resultaten var mycket lovande. Experimentet i en laboratorielabyrint visade klart att 3D-sjökortet var effektivare än både papperskartan och traditionell elektroniska kartor och intervjuerna och expertutvärderingarna visad på stort intresse från yrkesutövare i branschen.

The European Satellite Navigation Program is a case study that combines Technical / Public / Private aspects in an integrative way. Therefore, it is a sound case for a TPP thesis candidate. This thesis analyzes the European Union policies for the Galileo program, Europe's bid to have its own Global Navigation Satellite System (GNSS). Galileo is the Europe's first major attempt to develop a complex, Pan-European infrastructure project, to be owned by the European Union. It challenges its capability to gather strength and achieve the political capability to deal with major technology policy projects to lead in world affairs. It is a unique case that serves as a precedent for further infrastructure/technical projects to be managed by European Union institutions in the future. Such a major technology policy project involves the interrelation of a complex structure of multinational political and industrial organizations, and the interrelation of leading edge technical, economic, commercial and social concerns in the heart of the European Communities. During the last two decades Europe has committed to maintain a remarkable long-term vision and a strong political determination to developing Galileo. On the downside, the EU hashad difficulties in establishing a coherent financing program and a punctual manufacturer deployment. On the basis of the Galileo endeavor,this thesis assesses the use of Public Private Partnerships in large pan-European infrastructure projects in the complex political framework of the European Union. This analysis is performed upon the perspective of a theory of how to devise a strategy, a tactical plan, and a way to implement a technology policy effectively, developed by the guidelines set forth by the MIT Technology and Policy Program. It reviews the history of the European Union's policies attempting to develop Galileo, evaluates the strengths and weaknesses of such policies, and delivers a plan and a guide to help implement future projects more effectively. Finally, it aims to provide a set of recommendations for the future policymaking the European Union will face in the next decades with regard to the operation and exploitation of the system.

Texto completoFärgkodning ses i olika former inom media och verkliga livet. Denna studie fokuserarpå vad för effekt färgkodade visuella element kan ha på en spelare i ett videospel, medhjälp av ljus och miljö i ett videospel med avsiktlig färgkodning för att vägledaspelaren och fånga dennes uppmärksamhet. Resultaten föreslår att färgkodning hjälperspelaren att förstå vart de ska gå i datorspelet, samt vad något betyder. Deltagare anseratt deras förmåga att ta sig igenom spelets nivåer var enkelt tack vare deras förståelseav vad en färg kan antyda. Deltagarna valda för studien varierade i förmåga, ålder ochkön för att förhindra någon form av partiskhet. Vidare förebyggande av partiskhetgjordes via mellan-deltagare metoden, där deltagare startade på en slumpad nivå.

Texto completoDen här uppsatsen är en fördjupning i området människa-dator interaktion och användbarhet och börjar med en generell introduktion om ämnet inbyggda system som används i elektriska test- och verifieringsverktyg i industrin. Fortsättningsvis beskrivs en problemformulering och en förklaring av de produkter som är i fokus i denna studie. Företaget som studien är utförd hos utvecklar och tillverkar olika typer av provutrustning för elkraftsbranschen. Sådan mätutrustning ingår i begreppet intelligenta elektriska test- och verifieringsverktyg och hanteras med hjälp av inbyggda pekskärmar. Att ha ett användarbart grafiskt gränssnitt är viktigare idag än det var för många år sedan, detta eftersom företag konkurrerar med användbarhet i produkter och inte enbart med teknisk prestanda [4]. Därför är det viktigt att designa ett användargränssnitt och navigationsstruktur för att sammanföra ett företags alla produkter och skapa en känsla av igenkänning mellan dem. Ett bra mått på igenkänningsfaktorn är i det här fallet ett användargränssnitt och en navigationsstruktur som är igenkänningsbara och förstådda när slutanvändaren interagerar med olika typer av produkter. Informationsarkitektur och användardesign är inte alltid prioriterat hos ett industriellt företag då budgeten för tekniken är långt större än för användardesignen. Tidigare handlade informationsarkitektur mer om teknik, men nuförtiden är det mer om systeminformation och dess innehåll [8]. I den här studien har tre metoder använts för att samla data till och besvara frågan ”Är det möjligt att designa en homogen navigationsstruktur till olika typer av slutanvändare av elektriska test- och verifieringsverktyg?” Den här studien visar att det är svårt att erhålla ett rättframt och entydigt svar på ämnesområdet hur man designar en hållbar och homogen informations- och navigationsstruktur för intelligenta elektriska mätutrustningar. Studien påvisar också att en mängd information kan inhämtas genom att studera användbarhet med hjälp av olika testmetoder. Allt detta i syfte att ge en plattform till utvecklarna som kan agera grund för deras utvecklingsarbete med gränssnittet.

Subject:Navigation Using SLAM Vision Technology Student:Ken-Yen Lee Advisor:Jiun-Haur Tarn This thesis, does research about the solution for the navigation problem in mobile robotics by adopting Simultaneous Localization and Mapping (SLAM) algorithm. The algorithm uses only a single camera without odometry information. Estimations of vehicle motion and landmarks’ bearings are computed within a standard Extended Kalman Filter frame work. For prediction, IMU information is utilized to propagate the nonlinear vehicle kinematic equations. And the innovations are obtained from the differences between predictions and the measured landmarks’ bearings. Therefore, the proposed SLAM algorithms can be used as a navigation solution when GPS service is degraded or temporarily unavailable. For real-time implementation of the adopted MonoSLAM, we put together a C++ program with graphical user interface. In which we use library from OpneGL for graphical object. Also the Harris Corner Detection and Lucas-Kanade feature tracking algorithm from OpenCV library are integrated for keeping correct landmark correspondences as the vehicle moves through the scene. The proposed SLAM programs is simulated on a table-top personal computer, and subsequently tested in an open room, then an outdoor environment. For tests performed in the outdoor environment, vehicle trajectories from SLAM algorithms are compared with the on-board GPS information and excel. Keyword:SLAM, Visual System, Feature Tracking.

A portable navigation device (abbreviated as PND) is very popular during the past years. However the sales result became quite slow due to the economic recession in end of 2008, and the high inventory caused the price erosion and the total market size decreased in 2009. On the contra, GPS phone is increasing very rapidly, especially it became more and more popular on the smart phone which emphasis the navigation solution as one of the most important application. There are a lot of people predicting that PND will be replaced by GPS phone due to PND is dedicated for navigation functions. This prediction inspired the research subject: “Does GPS Smartphone can be really the substitute of PND?” “What’s consumers’ switching intention to use GPS Smartphone to replace their current PND?” Mio is the top 3 PND brand in worldwide GPS industry, and also the leading brand in Taiwan market. It had also accumulated around 250,000 VIP members during the past years. All the VIP members have highly connection with their database because map update and upgrade is very important for PND users. Normally, When Mio’s marketing team want to realize users’ intention toward new feature, their response rate for marketing research is very high. This thesis plans to utilize the high loyalty members’ database to issue the questionnaire, asking about the switching intention for using GPS Smart phone replacing PND on navigation function. By using Technology Acceptance Model (abbreviated as TAM), the purpose of this research is to find out how consumers recognize the navigation function for Smartphone and their intention for using it. Since users’ switching behavior is also under serious consideration, Theory of Reasoned Action (abbreviated as TRA) is another important theory model need to be verified. In addition, when consumers have the switching intention, they also concern about the cost of switching; therefore, we also use Switching Cost Theory to verify the thesis.
