Abstract
Disclosed herein are systems, methods, and devices for sensing touch at a surface. Sensing touch can be achieved while decreasing the number of sensors at a surface as well as data and computation complexity, but maintaining accuracy. Such sensing touch can be achieved via applying excitation and detecting emission waveforms at a surface that are associated with touch at a surface.
