Haptic feedback for touchpads and other touch controls
First Claim
1. A method for providing a user of a touch input device with interactive feedback, the method comprising:
- detecting a user interaction with a first portion of the touch input device, said interaction including exertion of a degree of pressure; and
generating a haptic force proportional to or variable with said degree of pressure.

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.

17. A method for providing interactive feedback to a user of a touch input device coupled to a display on which a graphical object and a cursor are displayed, the cursor being movable in the display in accordance with interaction by the user with the touch input device, said interaction including exertion of pressure, the method comprising:
-
determining the amount of pressure exerted; and
generating haptic force commensurate with the amount of pressure exerted. - View Dependent Claims (18, 19, 20, 21)
