Recently we attended an Italian hacking competition named WhyMCA - Hack Reality. This kind of event (also known as "hackaton") requires the participants to develop a working system within a given time span (8 hours in this case) and following a predefined topic. The "Hack Reality" was about the interaction between mobile technologies and the real world.
A collection of tasty tools were offered to let our creativity explode, such as Wikitude ARchitect, LEGO MINDSTORMS, Arduino/ADK, Microsoft Kinect, and so on.
There were four of us: me (Sebastiano), Dario, Stefano and Nicola, who was in Germany and therefore remotely joined the competition via Skype.
We called our project "Anti Theft Social System" (ATSS). As the name suggests, it's a an anti-theft system with a social component. Here's how it works.
We connected a motion sensor to a Nexus S device through the Arduino platform and we developed a simple Android application which controlled the aforementioned sensor. The application (i.e. the entire system) could either be activated/deactivated via 4-digit PIN code or via NFC tag. A movement within the sensor's range triggers the application which activates the phone's camera: while the movement persists, the camera keeps taking pictures of the scene. When either the movement stops or a timeout occurs, the application sends the captured pictures to our server, where they are assembled in a GIF animation. The server also triggers two more services: an alert text message ("Theft warning!") is sent to a set of predefined mobile numbers and a call with a pre-recorded audio message is performed to other predefined numbers (e.g. neighbours). The SMSs and phone calls were performed by means of the Tropo API.
The GIF image of the thief is shared on the owner's Twitter account. A PUSH notification is essentially sent to the victim's iOS device, where a simple application will then display the image sequence of the robber.
Our opponent's ideas were mostly valid and some of them were really brilliant..
But in the end we won the first prize! So here's a picture of us at the end of the day, very tired and very satisfied :D
Here's some pics of ATSS :)
