Capstone Spring 2011 2|Page Sophisticated Mobile Application using Augmented Reality Technology ABSTRACT In today’s world, mobile applications are triggering a fundamental shift in the way people experience computing and use mobile. The explosive growth in smartphones in the last three years facilitated the development of hundreds of thousands of mobile applications that promised to fundamentally change how people use the Web. Our mentor, Mr. Dilhar De Silva, CEO of AtLinks Communications, was interested in developing an android mobile prototype application using augmented reality technology. The overall goal of the project is to develop an Android-based augmented reality (AR) mobile application through which images and text can be placed on top of the objects of the phone camera view based on the geo-location of the objects detected by the phone. For example, using this application, administrative user can place the schedule of the event at a particular geo-code (latitude and longitude) on a server by using a web application and the mobile users can open the mobile application on android phone to view the augmented image of schedule overlying on camera’s view. Mobile user can also download the schedule into their mobile phones by providing their login credentials. To provide the necessary AR functionality, our team developed and used a metric to study about AR API’s and selected QUALCOMM API for pattern based augmentation, and WIKITUDE API for geo-code based augmentation. This project was carried out in accordance with Rational Unified Process (RUP), using Scrum process. The process went iteratively and incrementally delivering sprints and finally delivering the end product. The project will be documented using UML 2.0.

INTRODUCTION 1.1 Purpose The goal of our capstone project is to develop an Android-based augmented reality (AR) mobile application through which images and text can be placed on top of the objects of the phone camera view based on the geo-location of the objects detected by the phone. It will also develop a server-side web application where users can place graphical image at a specific geocode (location) using Google Maps. 1.2 Overview In today’s business and educational world, every industry and educational institutions wants to share any specific information at lightning speed. This may be a part of manufacturing industries promoting their new product, or shopping malls and restaurants promoting their new discount offers, or educational institutions announcing on-campus job vacancies and any special events etc. In the existing system, manufacturing industries does these promotions by displaying the new product details on big hoardings or by advertising it on Television. Shopping malls and restaurants promote their discount offers and by adding pamphlets in the daily news paper. Students of university have an only option of reaching the special event place to obtain the schedule of it. However the existing system of sharing the specific information to people has several drawbacks 1) Cost factor in case of advertising on TV and displaying large hoardings. 2) Pamphlets outmoded - Majority of the news paper readers are more interested on reading news rather than the pamphlets added in it. Capstone Spring 2011 5|Page Sophisticated Mobile Application using Augmented Reality Technology 3) Students would not know the schedule of an event unless they reach the place and also printing schedule brochures would add an extra budget to the event. In today’s world of technology, internet is one of the most important technological breakthroughs of the 20th century along with the mobile computing. “According to the results of a recent online survey conducted by IBM, television sets are losing ground to the internet when it comes to personal leisure time”[6]. These kinds of promotions and advertising based on the existing systems mentioned above are reaching to very less people. As the growth of internet and mobile users are growing day by day, all the mobile carrier services are offering smart phones to them at low prices possible with a contract based. Our mentor Mr. Dilhar De Silva wants us to build a mobile application on android using augmented reality technology to overcome the above drawbacks by targeting all the android mobile users as an initiative step. SMAART, an android-based augmented reality technology application makes android mobile phone users life easier in finding the information they looking for. Rather going to the places in person, an android mobile phone owner can download an augmented reality application/software that uses the phone's camera and GPS capabilities to gather information about the surrounding area. For example, if the user selects restaurants from the categories available, it shows information (order menu and discount offers) about restaurants in the area, overlaying this information on the phone's screen. You can even point the phone at a building, and it will tell you if any companies in that building are hiring by displaying a text image on your mobile Capstone Spring 2011 6|Page Sophisticated Mobile Application using Augmented Reality Technology phone. Aiming the camera towards the educational institution would fetch the mobile user with an event schedule overlying on the phone’s screen. The server side web application shall have a web based interface which uses Google Maps API to aid administrative users to place the images at specific geo-code locations. Using sensor services such as GPS, the mobile application shall get the current geo-code (latitude and Longitude).The current geo-code (latitude and Longitude) of the device along with user selection of categories and the radius (distance user wants to find places within) is sent to server to figure out if any images have been placed in the virtual world. The images that are augmented are displayed through the camera of the device. The mobile users then should be able to download and store the image augmented onto the device. Capstone Spring 2011 7|Page Sophisticated Mobile Application using Augmented Reality Technology 2. SOFTWARE DEVELOPMENT MODEL We used Rational Unified Process (RUP) as the software development model. It provides a disciplined approach to assign tasks and responsibilities within a development organization. The goal of RUP is to ensure the production of high-quality software that meets the needs of its endusers, within a predictable schedule and budget. Fig 1: RUP phases RUP has a project lifecycle that consists four phases. Inception: In the inception phase, the team met with Mr. Dilhar De Silva and gathered all the requirements. One of the requirements of our project is researching on different AR browsers and selecting the best open source browser that suites our project. We have selected Qualcomm API for pattern recognition and Wikitude API for geo-location. The team developed a basic use case diagram depending upon the requirements. Our team Capstone Spring 2011 8|Page Sophisticated Mobile Application using Augmented Reality Technology also made research on different kinds of android mobile phones and chose the Dell Streak for our project. We have also learnt about the Android SDK by dividing it into sections and later explained it each other. The team worked for almost three weeks in the inception phase. Elaboration: In the elaboration phase, we have revised the basic use case diagram. The team developed sequence diagrams as well. The team also designed a high level architecture diagram showing the flow of communication between the client and server. The team worked for four weeks in the elaboration phase. Construction: The construction phase was almost seven weeks. The team learnt new technologies like Android SDK, Qualcomm API, and Wikitude API. We have divided the team into two groups. One group working on server side and other group working on the client side. As we have divided the work, we were able to work independently and complete the project on time. Transition: During the transition phase, the team performed some tests to verify the project requirements. The prototype was demonstrated to Mr. Dilhar De Silva to validate that the project met the end users’ expectations. The team worked for two weeks on transition phase. Capstone Spring 2011 9|Page Sophisticated Mobile Application using Augmented Reality Technology 3. DESIGN AND IMPLEMENTATION 3.1 Architecture diagram: The architecture diagram shows the working of the project in detail. Images uploaded on to the server by authorized user will be stored on the database as shown in the diagram below. Client side mobile application receives the images from the server to augment it on the mobiles camera. The technical details of the project are explained in next section. Capstone Spring 2011 10 | P a g e Sophisticated Mobile Application using Augmented Reality Technology The communications between the client, server and database is explained Communication between Client & Server: 1. On the Android phone, the user shall select the category to view his required choice of images or text overlying on camera’s view by clicking on categories menu button. 2. A mobile user shall set the radius (maximum distance to consider from the current geocode) to display the requested category of images with in the distance of radius. 3. The current geo-code, along with selected categories and radius is sent to the server as a HTTP request. 4. The client application receives all the images of user-selected categories within the userdefined radius as an XML file from the server. 5. Once the augmented images are displayed on the camera’s view, user can select an image for download, which in turn requests for mobile user login credentials. 6. Once the mobile user provides the login information, server authenticates the user and then he/she would be able to download the image on to the device on a successful login. Communication between Server & Database: 1. When authorized users provide login credentials to logon to web application, the server checks with the database to authenticate them. 2. Whenever an authorized user adds an image along with the image name and description on the server side application at a specific geo-code, it is stored in to the database. 3. When a HTTP request with geo-code, informational categories and radius are received from client application, the server checks with the database to find images of the categories within a certain radius. Capstone Spring 2011 11 | P a g e Sophisticated Mobile Application using Augmented Reality Technology 4. TECHNICAL DETAILS This section explains the various technologies we used to develop this application. Mobile Application (Client Side): The Client side application was implemented using Java on Android 2.2 platform. We have used WIKITUDE API for augmenting images on camera view based on geo-code. We have used QUALCOMM API for augmenting image on camera view based on pattern recognition. We have also used Google Maps API on client side and placed markers on server-specific geo-codes. Web Application (Server Side): The Server side web application was implemented using Java server pages for user interface and MySql for the database. We have used Google Maps API to place the marker and add images with description at user-specific geo-code. Capstone Spring 2011 12 | P a g e Sophisticated Mobile Application using Augmented Reality Technology 5. TECHNICAL CHALLENGES AND LESSONS LEARNT 5.1 Selection of Android Mobile phone The first challenge the team had was, determining what Android phone to use for the project. The team gathered all the requirements of the project to determine the required functionalities of android phone. The team determined that, an android phone supporting a Qualcomm API and GPS would be the most reliable for the application. The team has done good research and selected some android phones which have satisfied the requirements criteria. By comparing the chosen android phones based on certain metrics, the team has decided Dell Streak 5 will satisfy the requirements of the project. The Dell Streak 5 has a built-in Qualcomm chip and GPS which would be used both for pattern recognition and geo-code based augmentation. Both mentor and instructor have agreed and recommended our selection of android phone. 5.2 Selection of Augmented Reality Browser/Engine Another challenge the team had was determining the best AR browser/engine for the project. AR browser/engine is used to augment images or text on top of the objects of camera’s view in our project. The team has done research on it and come across many AR browsers/engines. Based on the metrics, the team has compared all the AR browsers/engines and found Qualcomm API is best suitable for a pattern-based augmentation. Qualcomm API is an open sourced API and does not augment images based on the geo-code; it augments images based on pattern recognition. The team has determined Wikitude API as the best AR browser in augmenting images based on the geocode. Wikitude API is an open sourced browser and it is very well documented. Capstone Spring 2011 13 | P a g e Sophisticated Mobile Application using Augmented Reality Technology 6. CONCLUSION Our team was successful in completing all the requirements that were specified, even though the concept of augmented reality was entirely new for all our team members. In the process of completing this project, we were able to learn various new technologies. Learning all these new technologies and providing a working prototype in the short aggressive schedule was challenging. The team enjoyed working with the mentors and getting the opportunity to learn from this project. Overall, we had good experience working on the capstone project. 7. FUTURE WORK In future, performance of the application (SMAART) can be improved using WIKITUDE API to augment images on camera based on geo-location. SMAART, an augmented reality based android application has also been able to augment images on camera using a basic pattern recognition with the help of Qualcomm API. There is lot of scope to enhance on pattern recognition based augmentation in this application.
