Haptic feedback for touchpads and other touch controls
First Claim
1. A haptic feedback device, comprising:
- a touch screen configured to display a graphical environment and to output a first signal associated with a selection of a graphical object of the graphical environment, wherein the touch screen comprises a first region in which the graphical object is displayed and a second region configured to provide a second signal different from the first signal and associated with a control functionality different from the selected graphical object, and wherein the first and second regions are associated with different haptic effects; and
at least a first actuator configured to impart a first force to thereby provide a haptic effect in response to the selection of the graphical object or the control functionality , the first force based on information output by a computer 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.

33. A haptic feedback device, comprising:
-
a touch screen operative to output a first signal comprising coordinates of a contacted location on the touch screen, wherein the touch screen includes a first region associated with a cursor positioning, and at least one other non-overlapping control region not related to cursor positioning; a computer configured to receive the first signal; and at least one actuator coupled to the touch screen and configured to impart a force to the touch screen to thereby provide a haptic effect in response to said contact, the force being based on a second signal output by the computer, wherein the first region is associated with a first haptic effect different from a second haptic effect associated with the at least one other non-overlapping control region. - View Dependent Claims (34, 35, 36, 37, 38, 39)
