Abstract

In an embodiment, a haptic feedback system includes a plurality of actuators to provide tactile feedback associated with an input surface. Each actuator is adapted to be activated independently of the other actuators. The system further includes a controller to activate a first actuator of the plurality of actuators to induce a first vibration at a selected input location of the input surface and to activate one or more additional actuators to induce at least a second vibration to localize the first vibration at the selected input location.

Description

[0001] Cross References to Related Applications [0002] This patent application claims priority to US Patent Application Serial No. 12 / 504,821, filed July 17, 2009, which is hereby incorporated by reference in its entirety. Background technique [0003] The present disclosure relates generally to methods and apparatus for providing haptic feedback, and more particularly to methods and apparatus for localizing haptic feedback by limiting vibrational crosstalk effects between feedback locations. [0004] The term "haptic" refers to a touch or tactile sensation, and the term "haptic feedback system" refers to a system configured to provide selective tactile feedback at a contact location on a surface in response to user contact with the location. A system for knowing feedback sensations (such as vibration or other physical sensations, etc.). Such tactile feedback systems include an input surface and one or more actuators (eg, piezoelectric transducers, electronics, and / or othe...
