Haptic feedback for touchpads and other touch control
First Claim
1. A haptic feedback device comprising:
- a user interface device responsive to dynamic and static interactions between a user and the user interface device, wherein the user interface device is configured to distinguish between the dynamic and static interactions between the user and the user interface device; and
an actuator configured to impart a haptic effect to be felt by the user in response to a dynamic interaction between the user and the user interface device.

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.

19. A method of haptic feedback at a haptic feedback device, comprising:
-
responding, by a user interface device of the haptic feedback device, to dynamic and static interactions between a user and the user interface device; distinguishing, by the user interface device of the haptic feedback device, between dynamic and static interactions between the user and the user interface device; and imparting, by an actuator of the haptic feedback device, a haptic effect to be felt by the user in response to a dynamic interaction between the user and the user interface device. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36)
