AlexMiller11 has introduced a DIY gesture-sensing remote control project, designed to mimic a Bluetooth keyboard’s functionality. This innovative device offers precise control over media playback and presentations on a computer through Bluetooth connectivity. It distinguishes eight distinct gestures to interact with and manipulate a host PC.
The hardware backbone of this project is the Silicon Labs xG24 development kit, a compact IoT-focused board that can be conveniently powered by a CR2032 cell. Its core sensing capability lies in a six-axis IMU sensor, which collects motion data. The real magic happens in the software, which interprets this data and translates it into user gestures. This interpretation process is achieved using Neuton.AI’s model and SDK, a compact yet efficient machine learning framework tailored for small devices.
Functionally, this device emulates a Bluetooth Human Interface Device (HID) and connects to a computer just like a standard Bluetooth keyboard. Once paired, the recognized gestures are relayed via the serial port and sent over Bluetooth to the host PC. This allows users to seamlessly control media playback, adjust volume, manage presentations, and more. Detailed information about the project, including code and resources, can be found on the project’s GitHub repository. For a better understanding of how it works, there is also a demo video provided on the project’s page.
