DeskWave

Abstract

Microwaves are a type of electromagnetic radiation that can pass through a variety of commonly found materials but partially reflect off human bodies. Microwaves are nonionizing and at controlled levels do not pose a danger. A wave that is capable of passing through materials could have useful applications in human-computer-interaction. However, only recently the full potential of microwaves for interactive devices has begun to be explored. Here, we present a scalable, low-cost system using an array of offthe-shelf microwave Doppler sensors and explore its potential for tabletop interactions. The arrays are installed beneath a desk, making it an ubiquitous device that enables a wide range of interactions such as 3D hand tracking, gesture recognition and different forms of tangible interaction. Given the low cost and availability of these sensors, we expect that this work will stimulate future interactive devices that employ microwave sensors.

“…RF sensing has been used for analysing walking patterns or gait [7,33,62], tracking sleep quality and breathing patterns [43,70], and recognising movements of body parts such as hands for interactive purposes [14,25,28,36,37,41,60]. The radars used in these studies operated at various frequencies, ranging from 2.4 GHz [60,70] to 24 GHz [28,43].…”

“…In the health domain, radar enables non-invasive monitoring of glucose levels [34,50], sleep monitoring [42], and emotion tracking [65]. Finally, a radar sensor can distinguish various materials when placed on top of it [30,63].…”
