Portrait of Jonathan Westhues

Jonathan Westhues

Principal Research Manager


My group developed the capacitive touch and stylus controller shipped in Surface Hub, starting from work that I performed at Perceptive Pixel, Inc. before its acquisition. That spanned all aspects of this design, from sensor electrostatics to the image processing and other higher-level software. I’m interested in capacitive user interfaces, and the novel application of concepts from digital signal processing and communications to improve performance in such systems. My current work relates to interfaces with similar underlying physics that go beyond finger touch and stylus, and to displays and user input more generally.
