1. A haptic device, comprising:
- a touch surface configured to sense a first event;
a first plurality of haptic actuators coupled to the touch surface, each of the first plurality of haptic actuators configured to generate at least one haptic waveform pulse to provide haptic feedback to the touch surface in response to the first event; and
a second plurality of haptic actuators coupled to the touch surface, each of the second plurality of haptic actuators configured to generate at least one canceling haptic waveform pulse to minimize unwanted haptic effects on the touch surface in accordance with the first event.

Abstract
A method and device for generating haptic feedback over a touch surface using multi-actuated waveform phasing are disclosed. A haptic device, in one embodiment, includes a touch surface and a group of haptic actuators. The touch surface is capable of sensing an event, wherein the event can be a contact on the touch surface or a movement nearby the surface. A portion of the haptic actuators, which are coupled to the touch surface, is configured to provide haptic feedback on the touch surface in response to the event. Another portion of the haptic actuators is used to minimize unwanted haptic effect on the touch surface.

12. A method of providing haptic feedback, comprising:
-
detecting a first interaction on a flexible surface; determining a first location on the flexible surface in response to the first interaction; calculating a first distance from a first haptic actuator to the first location and a second distance from a second haptic actuator to the first location; and activating the first haptic actuator to generate a first haptic waveform pulse in response to the first distance and the second haptic actuator to generate a second haptic waveform pulse in response to the second distance to generate haptic feedback at the first location. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)

21. A method of providing haptic feedback, comprising:
-
detecting a first interaction at a first location on a flexible surface; generating a plurality of haptic waveform pulses with a first plurality of actuators to provide haptic feedback to the first location on the flexible surface in response to the detecting; and generating a plurality of canceling haptic waveform pulses with a second plurality of actuators to minimize unwanted haptic effects on the flexible surface at locations other than the first location. - View Dependent Claims (22)
