I'm one of 80 developers worldwide to be accepted into Google's Project Soli Alpha Developer Program and was one of only 14 Alpha Developers to be invited to Google HQ to workshop new ideas regarding potential applications using SOLI. Specifically, my work involved investigating Soli's potential use in new musical instruments. A teaser of it can be seen in this recent video presented by ATAP at this Google I/O 2016.
This research was published in O Soli Mio: Exploring Millimeter Wave Radar for Musical Interaction, co-written with Francisco Bernardo and Paul Batchelor, at the NIME 2017 Conference in Copenhagen.
