Blueberry-Pi
Mobile gesture recognition glove to send hand orientation data to the Unity Engine over a Wi-Fi network.

Server-side
The Raspberry-Pi is expected to run the device.py script. The Raspberry-Pi interfaces with the 9-DOF sensor pack with the NXP module. The server Wi-Fi module immediately sends the data to the network through a TCP packet formatted in json string.
Client-side
The client-side (PC) will be running the Unity simulation located in blueberry-pi/sim. The Wi-Fi module will immediately store the received packets into a string FIFO to be parsed and stored into the float FIFOs for sensor data. The player movement module will read from the sensor FIFO and create movements in the simulation accordingly.
