An arduino, some sensors, some projectors, and a table combine to make an interactive system.
We are using a ADXL345 Accelerometer to detect motion in the table. The primary use will be to determine if there is a tap on the table. We are looking into wether these will also help us deteremine tap position.
We are using the Arduino MEGA 2560 to get information from the accelerometers. We are also using the Arduino Leonardo to act as a HID to have the system act effectively as a mouse.
We are using 2 Raspberry Pis to process and transfer information between the two arduinos.
We are using the Kinect to detect hand motions and handle interactions that might happen off the table.
