Jazz Hands is a system designed to allow a smartphone's audio output to be controlled by a predetermined set of gestures. Jazz Hands is comprised of the Nordic nRF51822 platform, Sparkfun's APDS-9960 RGB Light and Gesture Sensor, and a 4D 24PTU LCD.
The Nordic nRf51822 platform was chosen because of its on board Bluetooth capability.
The Nordic comucicates with the LPC1768 through six digital IN/OUTs, in order to display the command indicator on the LCD.
The Gesture Sensor is used to read in four gestures: Forward, Back, Left, and Right.
The uLCD displays an indicator to show which direction was swiped or an error if gesture was unable to be determined.
Note: The LCD requires 5V and the Nordic can only supply 3.3V, so the LCP1768 is used to supply power to the LCD.
Android App Functionality
Puck Central is used to take the received data from the Nordic and utilize it as commands for the mobile device it is being used on. Currently, the commands are set to be:
