We present Pyro, a micro thumb-tip gesture recognition technique based on thermal infrared signals radiating from the fingers. Pyro uses a compact, low-power passive sensor, making it suitable for wearable and mobile applications. To demonstrate the feasibility of Pyro, we developed a self-contained prototype consisting of the infrared pyroelectric sensor, a custom sensing circuit, and software for signal processing and machine learning. A ten-participant user study yielded a 93.9% cross-validation accuracy and 84.9% leave-one-session-out accuracy on six thumb-tip gestures. Subsequent lab studies demonstrated Pyroโs robustness to varying light conditions, hand temperatures, and background motion. We conclude by discussing the insights we gained from this work and future research questions.

Built on top of the wrnchAI SDK, we can now detect complex gestures and activities such as "wave", "fist pump", "come here" and "stop". Stay tuned, more activities and gestures coming soon.

Elliptic Labs has been showing off a brand new utility for its ultrasound-based gesture era at MWC in Barcelona, and we stuck up with the company to get a demo. The concept is that smart speakers with ultrasound digital sensor technology inner can locate the presence of people and respond to a variety of gestures.
