Project Hawaii

Established: November 9, 2012

The Project Hawaii program was discontinued on October 8, 2013.

With Project Hawaii, you can develop cloud-enhanced mobile applications that access a set of cloud services and Windows Azure for computation and data storage. Project Hawaii provides the tools and services; you provide the creativity and imagination.

Project Hawaii Cloud Services

The Project Hawaii SDK enables you to create of applications that take advantage of research cloud services.

The following cloud services are included in the Project Hawaii SDK:

  • Social Mobile Sharing (SMASH) Service
    The Smash service is a client-server system that enables rapid prototyping and development of solutions for social computing scenarios on Windows desktop and Windows Phone mobile platforms. Smash provides a general sharing mechanism for observable collections, and is part of the Project Hawaii SDK.
  • Path Prediction Service
    This service enables a mobile application to predict a user’s destination based on current route data.
  • Key-Value Store Service
    This service provides a simple key-value store for mobile applications. With this service, an application can store and retrieve application-wide state information as text by using key-value pairs.
  • Translator Service
    This service provides an interface to Microsoft Translator. It enables a mobile application to translate text from one language to another and to obtain an audio stream that renders a string in a spoken language.
  • Relay Service
    This service provides a relay point in the cloud that mobile applications can use to communicate. It provides an endpoint naming scheme and buffering for sent messages.
  • Rendezvous Service
    This service is a mapping service from well-known human-readable names to endpoints in the Hawaii Relay Service. This service uses well-known human-readable names as stable rendezvous points that can be compiled into applications.
  • Optical Character Recognition (OCR) Service
    This service takes a photographic image that contains some text and returns the text. For example, given a JPEG image of a road sign, the service would return the text of the sign.
  • Speech-to-Text Service
    This service takes a spoken phrase and returns text (currently in English only).

Application Analytics

We are pleased to offer a new application analytics service called AppInsight to project Hawaii participants. AppInsight provides you with detailed insights into how your application is being used in the wild – who your users are, when they use your app, and how they use it. AppInsight can also tell you where the performance bottlenecks in your app are, and which features of your app are being used the most.

Best of all, you don’t have to write a single new line of code to do all this! Just run your final XAP through our instrumenter and you can start seeing usage data right away.

Blind Helper is developed to assist people who are blind or visually impaired to identify their locations and contact with other people using smart mobile phones.

Mohamed Abd El Aziz, Karim HabakEgypt-Japan University of Science and Technology


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.

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, 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.

Securely Expanding the Web of Data to Smartphones

Data Silos are a threat to the openness of the web and hampers the potentialbenefits of the free flow of information (often referred to as Linked Data orthe Semantic Web). The modern smartphone is an example of a Data Silo, butthere are legitimate privacy concerns with allowing personal data from asmartphone device to be freely accessible. Existing solutions for makingpersonal data on a smartphone more widely available do not currently meet theneeds of a Linked Data architecture. In this paper we describe how to securelyexpose personal Linked Data from your smartphone device to authorized 3rdparties using the OAuth protocol. A proof of concept architecture OAuth basedarchitecture tackles the 3 primary data silo challenges of Duplicated Data,Ad-hoc Integration, and Data Migration. The architecture includes a OAuth 2.0server component that is connected to a mobile device via a cross-platformmobile application utilizing Phone Gap technology. We evaluate thisarchitecture and prove it to be effective. We show that highly valuablepersonal information that is locked within a smartphone can be shared in asecure way on the Semantic Web.

Anywhere, Anytime, Configurable Real-time Monitoring of 802.11 Networks

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.

QUEST7: A Real Life Search Agent

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.

Alpha Marauders

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.

Adaptive Accuracy-aware Localization for Smart Phones

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.

Illinois Phone

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.

MobiSafe: Avoiding Phone-calls when Driving

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.

Photo-Location Service

Photo-Location Service allows users to store photos and locations to the cloud and then retrieve photos that were taken by other users near the location of the current user. Our Photo-Location service involved two parts: the server and the client. We leveraged the Windows Azure Services and Project Hawaii in this homework project. The two services we used were Location and Storage.

Accelerometer augmented GPS for Energy-efficient Localization

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.

CollaboratoSense: Image stitching to generate 3D Models

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.

Personalized Search Profiler

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.

Test and Deploy your Applications

To test and deploy your applications on an actual device, you will need to get an App Hub membership to unlock a phone. Students may register for a one-year free membership. You need to complete all the steps below to unlock a phone for application testing.

How to Register with App Hub

Step 1: Verify as a Student with DreamSpark

  1. Go to
  2. Sign in with a Live ID. (If you don’t have, you can create one.)
  3. Click Get Verified.
  4. In the form, select your country from the list, click Verify as a student, click Get verified through my school, and then click Continue.
  5. Select your school.
  6. For some schools you can verify directly by using a university email ID and password or browser certificates. Otherwise, fill out the form that comes up with your name, date of birth, and email address. The email address has to be an .edu address.
  7. DreamSpark will send you a mail with the activation link. Click it to activate.You are now verified as a student and you can download any academic software from DreamSpark for free!

Step 2: Begin App Hub Registration

  1. Go to the App Hub Registration Page.
  2. Select your country, select account type as student, and fill out your personal information. Pick a developer name and gamer tag.Note It won’t ask you for payment as student registration is free.
  3. When you receive the an email with an activation link to verify your email address, click the link to activate it.You are now ready to submit apps to App Hub.
  4. In App Hub, click my dashboard > Windows phone.Although the status says that “GeoTrust is verifying the information you provided,” for student accounts that process does not start until you submit you first app. And until GeoTrust completes the identify verification, you cannot deploy and run applications on the phone. So we recommend you submit a test app just to get the GeoTrust verification process started.

Step 3: Submit an Application (to start GeoTrust verification process)

Note The purpose this step is to submit a test app to get the GeoTrust process started. The app you submit in this step does not need to be published in the Marketplace. You can withdraw it before that happens.

  1. Write a very simple application (or use the example app from the tutorial).
  2. Make sure the app works on the emulator.
  3. Go to App Hub and submit the app. In addition to submitting the .xap file, you will need to make and submit a few pictures (icons and screenshots).Read the full requirements.

Step 4: Identify Verification with GeoTrust

  1. After you submit the test app, even before the app is tested, the GeoTrust verification will kick off. Within 24 hours you will get a mail from GeoTrust.
  2. The email will contain a link to fill out a personal information form. If you have a SSN number, the process is straight forward.After you fill the form with your SSN, they will look up your credit info and ask a few multiple choice questions (based on the credit info) that are known only to you. If you get them correct, the verification process is complete! (If you do not have an SSN, or credit info, or if you do not get the multiple choice questions correct, GeoTrust may ask you to mail or fax some documents).Note After the verification is complete you can withdraw your submitted application from the Testing phase if you think your application is incomplete or is too simple.
  3. After the verification is complete, you can unlock your phone to deploy applications.

Step 5: Unlock the Phone to Deploy Applications

Follow the MSDN how-to instructions, or follow these instructions:

  1. Install the Zune software.
  2. Connect the phone to the PC. Leave the phone screen on.
  3. Click Run All Programs > Microsoft Phone Developer Tools > Windows Phone Developer Registration.
  4. Type your Live ID and password, and click Register.

Now you can deploy applications on the phone and test them (any application, not just the one you submitted to kick off GeoTrust verification above). In Visual Studio, click Windows Phone 7 Device instead of Windows Phone 7 Emulator as the target. Your app runs on the phone. Have fun!

Damn! Why does my phone die when I need it most? Energy Management?


There is a natural synergy between mobile devices and cloud services:

  • Smart phone devices have reduced CPU processing capability, reduced storage capacity, and limited battery. Most smart phones contain a variety of sensors, such as accelerometer, GPS, gyroscope, and camera, that helps users navigate thru their space.
  • Cloud services have seemingly limitless compute, storage, and networking resources, can quickly scale out with demand, and have a steady power supply.

Project Hawaii enables you to develop inventive cloud-enhanced Windows Phone applications.
