Capacitive Sensing 3D-printed Wristband for Enriched Hand Gesture Recognition

Abstract

In this work, we design a wearable-form hand gesture recognition system using capacitive sensing technique. Our proposed system includes a 3D printed wristband, capacitive sensors arrays in a flexible circuit board, a low-cost micro-controller unit and wireless communication module (BLE). In particular, the wristband manipulates the changes in capacitance from multiple capacitive sensors to recognize and detect users' hand gestures. The software stack translates the detected gestures into control command for application layer, together with an user-friendly web interface that supports both data communication and training between the wristband and the host PC. We also release an open API of our designed system for future applications. Lastly, we envision our system open API will be available for developers to customize vast range of hand gesture and integrate the wristband into various applications, from command on remote computer to video game controller.
