Abstract
Systems, methods, and apparatuses for rendering fine detail surface geometry on an active surface haptic display. One system includes a haptic surface, a plurality of actuators and a plurality of channel decorrelator elements. Each actuator is configured to generate mechanical waves in the haptic surface through control of each of the plurality of actuators, and wherein individual pixels of a plurality of pixels of the haptic surface are individually addressable by multiplexing of (either time or frequency of) the mechanical waves which generate mechanical displacement of one or more vector axes at locations of each of the individual pixels, wherein the plurality of channel decorrelator elements are located and configured to decorrelate different transmission paths between the plurality of actuators and the locations of the plurality of pixels on the haptic surface.
