Abstract
A three dimensional tactile feedback includes a two dimensional array of ultrasonic transducers and a control device configured to control the ultrasonic transducers. The ultrasonic transducers re configured to project discrete points of tactile feedback in three dimensional space. The tactile feedback system is configured to continuously switch the discrete points of tactile feedback at a frequency at which a human is capable of perceiving tactile stimulation in order to produce tactile stimulation of a three dimensional object in free space.
