Patent ID: 8686952

Claim:
An apparatus providing multi-touch haptic feedback, comprising a touch pad having a touch sensitive surface arranged to receive a user provided multi-touch event associated with at least two different locations on the touch sensitive surface; a multi-touch detection mechanism operatively coupled to the touch sensitive surface that detects the multi-touch event and generates a corresponding a multi-touch signal; and a plurality of haptic feedback devices operatively coupled to the multi-touch detection mechanism and the touch sensitive surface; wherein the plurality of haptic devices are disposed beneath the touch sensitive surface and are cooperatively arranged to concurrently provide tactile feedback in the form of vibro-tactile sensations at each of the at least two different locations on the touch sensitive surface in response to the multi-touch signal; and at least two nearby haptic devices of the plurality of haptic feedback devices concurrently respond to the user provided multi-touch event to form a single compound haptic response to the user provided multi-touch event; the single compound haptic response differs from a haptic response provided by either of the at least two nearby haptic feedback devices operating alone; and the haptic responses provided by the at least two nearby haptic devices of the plurality of haptic feedback devices to form the single compound haptic response differ from each other.
