Embedded Bytes has the opportunity of designing 100% of the firmware for the QuadJoy and the Command and Control Center. These devices quadriplegics interact with the world. The QuadJoy is a highly configurable Sip-n-Puff Device that converts gestures into actions. The QuadJoy can act as a mouse, keyboard, and joystick. It can operate wired through USB or wirelessly through Bluetooth. The Command and Control Center is a separate module which allows interfacing with infrared devices, additional Bluetooth devices, and environmental controls. The QuadJoy interfaces with the Command and Control Center over a mini-DIN connection using a custom UART protocol.
