Soli: Ubiquitous Gesture Sensing with Millimeter Wave Radar

摘要

This paper presents Soli, a new, robust, high-resolution, low-power,rnminiature gesture sensing technology for human-computer interactionrnbased on millimeter-wave radar. We describe a new approachrnto developing a radar-based sensor optimized for human-computerrninteraction, building the sensor architecture from the ground uprnwith the inclusion of radar design principles, high temporal resolutionrngesture tracking, a hardware abstraction layer (HAL), a solidstaternradar chip and system architecture, interaction models andrngesture vocabularies, and gesture recognition. We demonstrate thatrnSoli can be used for robust gesture recognition and can track gesturesrnwith sub-millimeter accuracy, running at over 10,000 framesrnper second on embedded hardware.
