A Mobile Augmented Reality Application for Visualizing and Interacting with Online Data A mobile Augmented Reality application for visualizing and interacting with online data Author Nurane Kuqi Supervisor Aris Alissandrakis Co-supervisor Nico Reski Examiner Ilir Jusufi Exam date 30th May 2017 Subject Social Media and Web Technologies Level Master Course code 5ME11E i “Computing is not about computers anymore. It is about living.” Nicholas Negroponte (MIT Media Lab founder) ii Abstract Augmented Reality (AR) technology has recently received a lot of attention for hav- ing lots of potential for uses in a variety of contexts. From an interaction perspective, an important factor is not only the usability of the applications, but also the engage- ment that these allow. Of particular interest is the possibility of allowing users to interact with data from online sources via an Augmented Reality interface. The main focus of this master thesis is to create a mobile AR application that allows visualization and interaction with online data. For this purpose a prototype was designed and implemented using the Unity game engine with C# and the Vuforia SDK on the front-end (mobile app) and NodeJS with MongoDB on the back-end (database server). The prototype was tested, and also deployed in a two week user study to evaluate a) how the system allowed the participants to explore available data, and b) how the use of the system affected the participants daily behaviour. The results indicate that the prototype was well received by the users. They enjoyed the experience not only due to the functionality of the system, but also given the opportunity for better involvement and completion of the given task (scheduling their lunch at the university campus restaurant) successfully. The outcomes of the thesis are a proposed architecture for a mobile AR system that allows users to interact in an engaging manner with online data, the developed pro- totype, and the initial testing and evaluation of the prototype in a specific use case. It is hoped that this work constructively contributes to the overall Augmented Real- ity field, especially regarding the development of mobile Augmented Reality appli- cations. Keywords: Augmented Reality, mobile Augmented Reality, AR Cube, Vuforia, Unity 3D, NodeJS, MongoDB. iii Acknowledgements In order to successfully complete the Master Studies, many components have given support financially, spiritually and academically. First, I want to thank the Swedish Institute for the scholarship provision during these two years of studies. SI is the first institute that made possible a dream, to accomplish the master studies abroad. Throughout studies I have always thanked SI for this great opportunity to advance my knowledge in the IT field. I wish to express my sincere gratitude to the Professor Marcelo Milrad for providing me the opportunity to work as a student researcher within the Media Technology Department. I would like to express my deepest appreciation to Dr. Aris Alissandrakis. Our first academic collaboration was throughout the student research work that I had within the Media Technology department. Based on the good working experience, I de- cided to chose him as a supervisor for my thesis. He has not only been a great mentor, but he has also supported me a lot to advance my skills and knowledge. In addition, as part of the academic level support, I want to thank Nico Reski, for his sincere support and technical consultancy. Nico has not only been a co-supervisor but also a great friend. I feel lucky for the possibility to have spent this journey with professional mentors that helped me advance through their consultancy, pro- fessional conduct and fruitful discussions. My family has been one of the key motivations for pursuing the studies abroad. Their support in everything and heart warming care has boosted my motivation to successfully complete the studies. My fiancé has played an important role on the whole journey. He has been the greatest support of mine during all this time. He has supported me in every step, with advices, technical support and has been with me in the bad and in the good. His unconditional love and help has motivated me to successfully pass the difficult battles throughout this time. I also want to thank all the friends that helped me through this masters. Their sup- port and fika time together helped me become a better person in life. Moreover, participants of the user study played a crucial role in the validation of the prototype. Thank you for the readiness to participate and add value to the study. In order to bridge the gaps throughout the phase of literature review and technical implementation I have consulted a lot of online resources from very scientific to less formal communities of people. I appreciate the work of each of the people that contribute to the shared knowledge online.

Invariably the technology enables a new means of interacting with screen-based entertainment or a computer game - 3DTV, the Nintendo Wii. The proliferation of so-called ‘smartphones’ with their abilities to run once-complex computer applications, in-built cameras and ‘GPS’ capability has unleashed the potential of ‘Augmented Reality’ – to date a regular feature of science fiction or ‘near future’ movies.

  • Context-Aware Mobile Augmented Reality Visualization in Construction Engineering Education
    CONTEXT-AWARE MOBILE AUGMENTED REALITY VISUALIZATION IN CONSTRUCTION ENGINEERING EDUCATION by AREZOO SHIRAZI B.S. University of Tehran, 2012 A thesis submitted in partial fulfillment of the requirements for the degree of Master of Science in the Department of Civil, Environmental, and Construction Engineering in the College of Engineering and Computer Sciences at the University of Central Florida Orlando, Florida Spring Term 2014 Major Professor: Amir H. Behzadan © 2014 Arezoo Shirazi ii ABSTRACT Recent studies suggest that the number of students pursuing science, technology, engineering, and mathematics (STEM) degrees has been generally decreasing. An extensive body of research cites the lack of motivation and engagement in the learning process as a major underlying reason of this decline. It has been discussed that if properly implemented, instructional technology can enhance student engagement and the quality of learning. Therefore, the main goal of this research is to implement and assess effectiveness of augmented reality (AR)-based pedagogical tools on student learning. For this purpose, two sets of experiments were designed and implemented in two different construction and civil engineering undergraduate level courses at the University of Central Florida (UCF). The first experiment was designed to systematically assess the effectiveness of a context-aware mobile AR tool (CAM-ART) in real classroom-scale environment. This tool was used to enhance traditional lecture-based instruction and information delivery by augmenting the contents of an ordinary textbook using computer- generated three-dimensional (3D) objects and other virtual multimedia (e.g. sound, video, graphs). The experiment conducted on two separate control and test groups and pre- and post- performance data as well as student perception of using CAM-ART was collected through several feedback questionnaires.

  • Challenges of a Pose Computation Augmented Reality Game Application
    Challenges of a Pose Computation Augmented Reality Game Application THESIS Presented in Partial Fulfillment of the Requirements for the Degree Master of Science in the Graduate School of The Ohio State University By Chiu Ni Wang Graduate Program in Computer Science and Engineering The Ohio State University 2011 Master's Examination Committee: Rajiv Ramnath, Advisor Jay Ramanathan Copyright by Chiu Ni Wang 2011 Abstract An Augmented Reality (AR) application combines the virtual world and reality to enhance the user‟s perception of the real world. Earlier, augmented reality technology had not found much commercial success because it required bulky gadgets and considerable processing power. But now AR technologies are available and computationally feasible on commodity mobile devices, such as smartphones. Pose estimation AR applications make use of inbuilt hardware features like the accelerometer, magnetometer and Global Positioning System (GPS) for overlaying images onto the real world. However, the dependence of the working of AR on hardware features gives rise to new challenges, which must be addressed in order to provide augmentation in as seamless a manner as possible. These challenges include real time estimation of the user‟s viewport, geo-magnetic sensor noise, the delay in receiving GPS data, and the synchronization of timer threads. Other challenges include those of debugging and testing because realistic GPS feeds and other sensory data are unavailable during development. Next, most AR applications have the need for common framework-based services, such as tracking, image registration and interface handling. This thesis also explores the feasibility of such a framework, where a reusable platform is coupled with a customizable application specific component to create the AR application.
