Abstract
A system and method for dynamically cancelling haptic feedback in certain areas of a touchpad, and/or to dynamically isolating haptic feedback in certain areas of the touchpad, may enhance flexibility, utility and functionality of the touchpad. A first haptic engine may generate and transmit haptic feedback in response to an input detected in an input area of the touchpad. A second haptic engine may generate haptic cancellation feedback, and transmit the cancellation feedback after a time delay, to cancel out the effect of the haptic feedback in a cancellation area of the touchpad. This may allow a user to experience the haptic feedback in response to an input in the input area, and to rest hand(s) on other portions of the touchpad display without feeling haptic feedback in the other portions of the touchpad.
