Multi touch with multi haptics

摘要

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.

主权项

1. An electronic device, 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 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; andthe 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.
