New radar kit can recognize objects and material

posted by Jason Kottke   Nov 07, 2016

Soli is a newish project by Google described as “a new sensing technology that uses miniature radar to detect touchless gesture interactions”. It’s pretty cool. A group at The University of St. Andrews has found another potentially more amazing use for the sensor: recognizing specific objects and materials.

RadarCat (Radar Categorization for Input & Interaction) is a small, versatile radar-based system for material and object classification which enables new forms of everyday proximate interaction with digital devices. In this work we demonstrate that we can train and classify different types of objects which we can then recognize in real time. Our studies include everyday objects and materials, transparent materials and different body parts. Our videos demonstrate four working examples including a physical object dictionary, painting and photo editing application, body shortcuts and automatic refill based on RadarCat.

More simply put, if you put an orange on the sensor, it knows it’s an orange…and the system can learn new objects as well. It’s a barcode scanner without barcodes. Watch the video…you’ll get the idea pretty quickly.
