Classelect is a mobile app that targets to facilitate course selection out of a university curriculum and is based on three principles: Requirements (of the curriculum), Reviews & Ratings (of classes, professors etc. by students), and Recommendations (for classes you could//should take). Let’s face it, those generic course descriptions on college websites are just not enough. You don’t get to know enough about the material, nature, usefulness, the professors or just about anything about the class. If you’re lucky, all you learn is about the topics covered. These descriptions become even more important when you have multiple classes, or potentially, multiple career paths to choose from. With Class Select we aim to empower students, of any sort of education institution, to learn more about these classes they are about to take from students who have “been there, done that.” Not only can students learn about what other students think about various classes & professors, but they can also share their experiences with their peers. The app comes with some handy features which are motivated by the principles of web 2.0 and collective intelligence. Granted, there exists a fragmented market of such tools on the web, but such an idea, or app, to our knowledge does not exist on mobile platform yet. And since the future is going to be “mobile,” there exists the need for such a tool for students, who are one of the most technologically active groups nowadays.

In recent years the Restaurant Industry has begun catching on to the new wave of technology and social media outlets available everywhere. A few groups, such as OpenTable and GrubHub.com, are trying to capitalize on this new wave by providing a means to make reservations from your phone or by providing an interface to order online. However, the in-restaurant experience has been entirely static for years and years, even though there are some key weak points that could be improved with a little more technology. Our mobile and web application, GOUR, is a way to drastically improve the ins and outs of the restaurant experience. With GOUR, you can search for, make reservations for, and see all the reviews for the restaurant of your choice. Once you have made your choice, using GOUR, you can pre-order your meal, days in advance, so that it is ready once you and your party arrive. Then you can amend your order, call for service, and even pay, all using GOUR. Our platform makes it easy for the restaurant to schedule reservations, see which tables have which customers and which orders, and track which parties need assistance (for more water, or ranch dressing). With GOUR, going out to eat is a smooth and painless experience where all of the resources you need are in the palm of your hand!

Drivers always face situations in which they drive on roads that they are not familiar with. Driving on unfamiliar roads makes the driver a good candidate of accidents especially in night trips. Many accidents happen on specific and known spots on the map over and over again due to the same reasons as in some areas people are driving so fast, not paying much attention to the road signs or the road nature. If you know ahead about these road issues, you’d drive safer and smoother than ever.
In our solution to this problem, We are targeting vehicle drivers. We deliver notification about what will driver face soon next on roads (about potholes, bumps, congestion, road exits, accidents, U-turns, etc..). Those notifications are precious for drivers to take their precautions before ahead facing those situations.

Data Silos are a threat to the openness of the web and hampers the potential benefits of the free flow of information (often referred to as Linked Data or the Semantic Web). The modern smartphone is an example of a Data Silo, but there are legitimate privacy concerns with allowing personal data from a smartphone device to be freely accessible. Existing solutions for making personal data on a smartphone more widely available do not currently meet the needs of a Linked Data architecture. In this paper we describe how to securely expose personal Linked Data from your smartphone device to authorized 3rd parties using the OAuth protocol. A proof of concept architecture OAuth based architecture tackles the 3 primary data silo challenges of Duplicated Data, Ad-hoc Integration, and Data Migration. The architecture includes a OAuth 2.0 server component that is connected to a mobile device via a cross-platform mobile application utilizing Phone Gap technology. We evaluate this architecture and prove it to be effective. We show that highly valuable personal information that is locked within a smartphone can be shared in a secure way on the Semantic Web.

This project aims to explore the feasibility of information leaking on the Windows Phone 7 platform. The project stores a user-entered message on a Windows Phone 7 and collects the device ID and user’s geolocation, which is then emailed to a remote recipient. Students discovered that, thanks to Microsoft’s security architecture, information leaking is difficult to achieve on the platform without attracting user attention (and suspicion).

Network administrators need a simple, low-cost solution that allows them to monitor their wireless networks in real-time at any time, from anywhere. Furthermore, network administrators have varying needs as to what metrics to gather from their network, and when to use each metric. In this work, we develop a proof-of-concept system that addresses these points. Our system consists of a Windows Phone 7 application which displays real-time information via polling a wireless network sniffer application for results on arbitrary metrics. We show that, upon further optimization, our solution is viable for use by network administrators in practice.

Human eyes have a limited range during each eye fixation. As a result, searching specific text in a document or an image is time consuming. In this paper, we design QUEST7, a real life search agent combining the advantage of mobile devices and cloud computing. Utilizing Optical Character Recognition (OCR) service provided by MSR Project Hawaii, we extract texts from images captured on a mobile device. Keywords are then highlighted for human use. Experiments show that QUEST7 is significantly faster and more accurate than human eyes for dense texts. Extensive measurements are carried out to identify sources of delays in the process. With 3G access, network transfer latency tends to dominate. In contrast, OCR on the cloud side contributes to most of the delay with Wi-Fi access.

This app is functionally a multiplayer game which is much like Worms, a turn based game where you need to wipe out another team by shooting projectiles at them. The basis of this game is two people are placed in an “arena” where they have to destroy the other team (consisting of two characters which are controlled by a single person). They then take turns moving their characters around and at the end of their turn they fire a projectile. They take turns at this process until the one’s team is completely destroyed. At this point, the game starts up with a main menu and you are prompted to join a game. After joining the game, the player needs to type in a game name which needs to match the player with whom you want to play against. The players are then put into a match against each other. As long as one has Wi-Fi activated and connected, one can play the game; otherwise one is not able to play the game. The reasoning behind developing this app is that small gimmick games are very popular, such as Angry Birds, Tiny Wings, and Fruit Ninja. This game is meant to entertain a person while they have a few minutes to waste.

Our project this semester is in collaboration with researchers at the Nation Center for Supercomputing Applications. It is essentially a system to enable personalized localized situational awareness by integrating heterogeneous sensor information. One might view it as Foursquare except that it is for emergencies. The basic premise is as follows: If you see an emergency before you or if you know of one happening nearby, you can quickly tweet about it and through the built in twitter plug in and it gets registered as an official tweet in your account. That information is then taken and overlayed onto Bing Maps; which any user with our app can view and see the exact location(via pushpins) that the incident occurred at and the detailed tweet associated with it. The user also has the option of viewing different layers on the map, in the event that they are looking for a specific type of event. Another important functionality is a slider that allows the user to view the change of the spatiotemporal animation on a map interface for heterogeneous sensor streams including OGC Web Mapping Services and citizen sensing twitter feeds. Each position of the slider corresponds to a time range (e.g. last 30 minutes, last 24 hours) and this allows the user to see all tweets that were posted within that time range as well as the weather radar information. We believe that with this as a basic premise, we have a prototype that could potentially be a very successful app, that people would use in the event of an emergency and would therefore get help warn others about the exact location and nature of the emergency.

Location-based smart phone applications like social networks, traffic information, health services, food services, entertainment, etc., are becoming increasingly popular, especially that GPS functionality is becoming a standard in new phones. However, GPS is a power hungry service, and using it as the only location service will quickly drain the phone’s battery especially if users need continuous updates from location-based applications. Moreover, GPS accuracy degrades in urban areas where tall buildings are present, and where the user needs accuracy the most. We propose and implement an energy-aware and accuracy-aware system that utilizes other common functionalities available in a smart phone, specifically: Bluetooth, WiFi, and accelerometer, to provide location information service that could be used by location-based applications. In Bluetooth, a smart phone device requiring to update its location information can scan nearby devices, and obtain the locations of those devices. Due to the relatively short range of Bluetooth, the device can safely copy the acquired location to be its own, and assign a 10m uncertainty on it. When using WiFi, by creating a network with nearby anchor nodes, the position of the device can be determined on triangulation basis. The accelerometer can predict how and where the device is moving, and using this data, the next position of the device could be estimated. Bluetooth, WiFi, and accelerometers require less power than GPS, but they provide varying accuracy depending on a user’s location. For example, WiFi would be more accurate than GPS in urban areas due to the high density of access points, and other people owning mobile devices. An investigation of the power consumption and accuracy of each of the four mentioned technologies will be made. An algorithm will be implemented to dynamically select the proper technology for the location service based on the input of the required accuracy, the detection of the current battery level, and the user’s setting for the battery quota provided for location-based applications. A Bayesian estimation framework will be used to model the investigated accuracy, and the available power, which can then be contrasted with the input requirement.

We propose to overhaul the current authentication system used on UIUC’s campus and automate and integrate other tasks such as room scheduling with our system. Our architecture proposes an innovative multi-step authentication approach to this problem so as to get around single point of failure. Given the proliferation of GPS enabled smart phones, each user in our system can be identified by their personal smart phones. The GPS within cell phones can authenticate that the given user is indeed within the building. Authenticating whether the user is indeed by the resource or a room to which access is being demanded however is non-trivial. We use QR codes as the second layer of authentication in our architecture for this purpose. The user can use the camera on his mobile phone and take a picture of the QR code and thus authenticate his presence right by the resource. This QR code is decoded and the string is sent to the cloud which then authenticates the user and could then unlock the resource for the user.

WiPAX is a chat client developed for Windows Phone 7. The client is built on the Extensible Messaging and Presence Protocol (XMPP), an open-standard communications protocol used by Google Talk, Jabber, and other chat providers. The ubiquity of XMPP allows WPAX users to communicate with any other users on the same protocol that have authorized them. Of particular interest, is Google Chat which has been adopted by a large number of users. We were able to find only one, poorly rated application on the Windows Phone 7 marketplace that offered Google Chat support, which was clearly still in the early stages of development. WPAX is a fast, simple, stable, easy-to-use alternative.

We are constantly bogged with mundane routines at certain locations. For e.g: 1) Sending SMS to someone when we reach home 2) Setting ringtone profile to silent in movie theaters/workplace/school 3) Launching certain apps at certain locations (for e.g. bus arrival app at bus stop). Since there is a correlation between the location we are in and the lists of actions we want our phone to do, we believe that building a Location aware action triggering like IntelligentMe will change the way people use their smart phone.

MobiSafe is an application that uses the Microsoft Hawaii GPS Wrapper, Skype4COM API, and a neural network service running on a server. MobiSafe is used to detect whether a driver is in a danger zone. Every driver offloads his location and speed to the server and the neural network engine and uses other input parameters (such as the number of past accidents around that location and the number of red lights around that location) to decide whether the driver is in a danger zone. Then the application intercepts an incoming call and reroutes it back to the caller, notifying that the driver is in a danger zone. By using MobiSafe, drivers are safe from being distracted by incoming calls. Also, it lets the caller know that the driver is driving and in a danger zone.

The idea is to build a phone application running on Windows Phone 7 to locate friends based on GPS coordinates: users can search for friends, know where they are and what they are doing. The application also allows users to find friends to join themselves in a certain setting by creating an event. The user can simply invite all his friends to the event and wait for their reply. With just a few clicks of the button, anyone can connect to their friends wherever they are.

The goal of this application is to minimize the energy consumption of localization using a GPS unit. The project uses an accelerometer to augment a GPS unit on a Windows Mobile phone. We are developing a HMM based algorithm to convert raw and noisy accelerometer readings into meaningful distance measures. Using an adaptive algorithm, our system will determine when to switch on the GPS unit such that accuracy is within acceptable limits (as determined by the application)—when the GPS unit is off, location is inferred from the accelerometer.

In this application, we use geo-tagged images taken using the windows mobile phone to generate 3D models outdoors and indoors. The mobile phones takes GPS annotated images outdoors, and accelerometer annotated images indoors and transfers it to back-end server. The backend server runs a clustering algorithm, an image stitching, and consequently a 3D model generator to generate 3D models of indoors and outdoors. Although not supported by the application yet, these models can be used to augment street views of Google Maps. The major advantage of the system is that it provides temporal consistency—the models are updated frequently based on how often pics are uploaded to the server.

The goal of this application is to collect data on important contexual information that can be used to build a personalized search engine for mobile phones. Personalized search refers to building user specific models and augmenting search queries with additional information specific to the user. Such a search engine on the phone can help minimize the number of unnecessary results retrieved from the backend search service like Bing or Google. Our application profiles data on web browsing history, search history, location, to-do and calendar items. We plan to use the collected data to study the efficacy of personalized search.
