Radar Sensing

RaITIn, a radar-based identification (ID) method for tangible interactions. Unlike conventional radar solutions, RaITIn can track and identify objects on a tabletop scale. We use frequency modulated continuous wave (FMCW) radar sensors to classify different objects embedded with low-cost radar reflectors of varying sizes on a tabletop setup.

RaITIn provides radar based identification for tangible tabletop interaction. It uses a miniaturized radar to identify unique, low-cost embedded reflectors. (a) Assembling of radar reflector ID’s, (b) The tangible tabletop interaction space, (c) Tangible User Interface application, (d) Context aware application, (e) Education application, (f) Game application.

Micro-motions are often difficult to incorporate in Virtual Reality (VR) while macro-motions are a popular interaction method, due to …

We introduce VRTwitch, a forearm-mounted wearable device that is able to sense micro hand motions.
