Quadrant: A Multichannel, Time-of-Flight Based Hand Tracking Interface for Computer Music
Chris Chronopoulos · 2021
Quadrant is a new human-computer interface based on an array of distance sensors. The hardware consists of 4 time-of-flight detectors and is designed to detect the position, velocity, and orientation of the user's hand in free space. Signal processing is used to recognize gestures and other events, which we map to a variety of musical parameters to demonstrate possible applications. We have developed Quadrant as an open-hardware circuit board, which acts as a USB controller to a host computer.
