Multi touch with multi haptics
First Claim
Patent Images
1. An electronic device, comprisinga touch sensitive surface arranged to receive a user provided multi-touch event associated with at least a first location and a second location 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 provides at least a first haptic response at the first location, a second haptic response at the second location, and a null response at a location between the first location and the second location by generating signals that destructively interfere with each other in response to the multi-touch event; and
the multi-touch detection mechanism determines a change to the multi-touch event and dynamically changes the first haptic response while the second haptic response remains static.

Abstract
Methods and systems for processing touch inputs are disclosed. The invention in one respect includes reading data from a multi-touch sensing device such as a multi-touch touch screen where the data pertains to touch input with respect to the multi-touch sensing device, and identifying at least one multi-touch gesture based on the data from the multi-touch sensing device and providing an appropriate multi-haptic response.

10. A method for processing a touch event at a touch sensitive surface, comprising:
-
receiving a user provided multi-touch event associated with at least a first location and a second location on a touch sensitive surface; detecting the multi-touch event; generating a multi-touch signal corresponding to the multi-touch event; responding to the multi-touch signal by a plurality of haptic feedback devices providing at least a first haptic response at the first location, a second haptic response at the second location, and a null response at a location proximate to the first location and the second location in response to the multi-touch event; determining a change to the multi-touch event; and dynamically changing the first haptic response while the second haptic response remains static. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)

19. A system for providing multi-touch haptic feedback, comprising:
-
a touch sensitive surface arranged to receive a user provided multi-touch event associated with at least a first location and a second location on the touch sensitive surface; a multi-touch detection mechanism that detects the multi-touch event and generates a corresponding a multi-touch signal; and a plurality of haptic feedback devices; wherein in response to the multi-touch event the plurality of haptic devices provides at least; a first haptic response at the first location; a second haptic response at the second location; and a null response at a location between the first location and the second location by generating signals that destructively interfere with each other. - View Dependent Claims (20)
