Rumblecation

=======

![Vibratory Communication Device](https://raw.githubusercontent.com/lab11/rumblecation/master/media/rumblecation.JPG)

Mobile phones have vibratory motors which can transmit vibration, and 

accelerometers, which can sense vibration. Rumblecation takes advantage

of this hardware to communicate over vibration. Vibratory communication

would limit the communication domain to two or more physically coupled

devices, and this could be used to pair a specific subset of devices

sharing a surface such as table. 

Custom hardware was developed to closely emulate the hardware found in

common smartphones. A simple protocol was then designed for vibratory

communication and firmware was developed for our hardware to implement

this protocol.

Current work is focused on improving data rate and reliability, which

should be achievable by improving the algorithms that are processing 

accelerometer data.
