Future Interfaces Group | BeamBand: Hand Gesture Sensing with Ultrasonic Beamforming @FiglabCMU | Uploaded 5 years ago | Updated 2 hours ago
BeamBand is a wrist-worn system that uses ultrasonic beamforming for hand gesture sensing. Using an array of small transducers, arranged on the wrist, we can ensemble acoustic wavefronts to project acoustic energy at specified angles and focal lengths. This allows us to interrogate the surface geometry of the hand with inaudible sound in a raster-scan-like manner, from multiple viewpoints. In our paper, we describe our software and hardware, and future avenues for integration into devices such as smartwatches and VR controllers.
