Haptic feedback for touchpads and other touch controls
First Claim
1. A method of selectively outputting haptic effects in a portable device comprising:
- sensing a user'"'"'s input on a touch screen of the portable device, wherein the user'"'"'s input is in contact with the touch screen;
outputting a haptic effect via an actuator to the portable device upon sensing the user'"'"'s input at a predetermined location on the touch screen;
sensing whether the user'"'"'s input remains in contact with the touch screen for a predetermined amount of time; and
terminating outputting the haptic effect when the contact with the touch screen exceeds the predetermined amount of time.

Abstract
A haptic feedback planar touch control used to provide input to a computer. A touch input device includes a planar touch surface that inputs a position signal to a processor of the computer based on a location of user contact on the touch surface. The computer can position a cursor in a displayed graphical environment based at least in part on the position signal, or perform a different function. At least one actuator is also coupled to the touch input device and outputs a force to provide a haptic sensation to the user contacting the touch surface. The touch input device can be a touchpad separate from the computer'"'"'s display screen, or can be a touch screen. Output haptic sensations on the touch input device can include pulses, vibrations, and spatial textures. The touch input device can include multiple different regions to control different computer functions.
