The Gesture Keyboard is a device that translates gestures into letters. It’s made by an Arduino Pro Micro, an HC-06 module for Bluetooth communication, and an MPU-6050 accelerometer.

The right hand controls rewind and fast forward. Raising both hands will start or stop playback. Of course, since the Arduino is reading the gestures you could change them to suit you.

The controller consists of a battery-powered Arduino MKR1000 with WiFi and an MPU6050 accelerometer. Held in the hand, the controller streams accelerometer data to an external PC, capturing the ...

The gyroscope/accelerometer data from his hand gestures are then fed directly from MPU-6050 back to the Raspberry Pi Pico.

The accelerometer uses sensors to detect the motion and speed of your hand, while the connected Arduino board will pick up on your motions and work out the commands.
