BeamBand: Hand Gesture Sensing with Ultrasonic Beamforming

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 ensem-ble acoustic wavefronts to project acoustic energy at spec-ified angles and focal lengths. This allows us to interro-gate the surface geometry of the hand…

Sozu: Self-Powered Radio Tags for Building-Scale Activity Sensing

Robust, wide-area sensing of human environments has been a long-standing research goal. We present Sozu, a new low-cost sensing system that can detect a wide range of events wirelessly, through walls and without line of sight, at whole-building scale. To achieve this in a battery-free manner, Sozu tags convert energy…

Interferi: Gesture Sensing using On-Body Acoustic Interferometry

Interferi is an on-body gesture sensing technique using acoustic interferometry. We use ultrasonic transducers resting on the skin to create acoustic interference patterns inside the wearer's body, which interact with anatomical features in complex, yet characteristic ways. We focus on two areas of the body with great…
