Abstract:
The present invention concerns a method and apparatus for the modulation of an acoustic field for providing tactile sensations. A method of creating haptic feedback using ultrasound is provided. The method comprises the steps of generating a plurality of ultrasound waves with a common focal point using a phased array of ultrasound transducers, the common focal point being a haptic feedback point, and modulating the generation of the ultrasound waves using a waveform selected to produce little or no audible sound at the haptic feedback point.

Claim (Index 31):
The method of  claim 21 , wherein the plurality of control points comprise a first group of control points and a second group of control points, wherein the acoustic field has a relatively high amplitude relative to the amplitude of the acoustic field at the second group of control points, wherein the acoustic field has a relatively low amplitude relative to the amplitude of the acoustic field at the first group of control points, and wherein the first group of control points are adjacent to the second group of control points so that a gradient in amplitude of the acoustic field is produced.
