Currently reported on Gizmodo: friend and collaborator Prof. Sidney Fels, University of British Columbia, and part of his team describe their work on using hand gestures to control speech and singing synthesis. Those interviewed in the video, including Sid, graduate student, Johnty Wang, Prof. Bob Pritchard (School of Music, UBC), professional classical vocalist Marguerite Witvoet are some the people I enjoy hanging out with when I attend the annual NIME conference, which Sid and I co-founded in 2001.
The video contains demos and an excerpt from a vocal performance by Marguerite.
