Android ADK based app for offer making based on location and

activity reportingJohn Waters

Project OverviewWith 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.

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

Further ADK Development

Create a usable product Add server communication to device app Increase user friendliness Possibly add non-smartphone access via SMS

etc.

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

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

Future of the System

Completion of each segment and link up of entire system

Undergo rigorous testingPossible trial with on campus outlet
