1. Android ADK based app for offer making based on location and activity reporting John Waters

2. Project Overview With the convergence of social networks and mobile devices, a wealth of new application areas has emerged. Services like Foursquare allow users to virtually check-in at a particular location and get money off offers from companies like Starbucks based on them checking in at various venues. This project aims to construct a system that combines mass movements of people, as observed through an Arduino-powered Open Hardware Platform (as supported by Google’s Android system) and an application running on an Android phone whereby a user (or multiple users) can report on their activity (e.g. in a lecture, not in a lecture) to their social network of choice. Location is automatically attached to these user reports via the Network Provider, Wi-Fi or possibly GPS.

3. Why Android? Around 3.7m devices using Google's Android operating software were switched on for the first time on Christmas Eve and Christmas Day alone

4. Why Android?  Apps developed in java  Open Platform & Open Source  Well Documented / Supported online

5. Entire System  User app  Business Device / app  Server / Database (connected via Internet)

6. System Diagram User Device Business Device Server/Database

7. Work To Date  Usable user app  Development of ADK hardware and app  Beginnings of Server / Database

8. Android User App  Ability to receive and send tweets  Re-login not required  Location tracking including attachment of location to tweets  Ability to detect proximity to specific business locations  Basic user notification on offer received

9. App GUI

11. Future App Development  Add link to server  Introduce more advanced features associated with Twitter  Develop the GUI further increasing user friendliness

13. Android ADK (Arduino Mega)

14.  Working communication link between android device (HTC Desire) and ADK  Android device app under development  Display hardware under development

15. Further ADK Development  Create a usable product  Add server communication to device app  Increase user friendliness  Possibly add non-smartphone access via SMS etc.

16. Server / Database  Allow user apps to upload the location data anonymously  Allow Business device to download appropriate data  Sort the data e.g. calculate the number of people at specific locations – track their movement

17. Server / Database  Server type: ASP.NET  Receives the data (location) from the user apps  Receives the offers from the Businesses  Sends specific data to the Businesses  Database: MySQL  Stores the user data collected from the twitter app (location)  Stores the offers available from the businesses

18. Future of the System  Completion of each segment and link up of entire system  Undergo rigorous testing  Possible trial with on campus outlet
