Haptic feedback for touchpads and other touch controls
DC CAFCFirst Claim
1. A haptic feedback device comprising:
- a display configured to display one or more graphical items, at least one of which has an active state; and
an actuator configured to impart to the haptic feedback device a haptic force associated with a displayed graphical item that is in an active state and a second haptic force associated with a displayed graphical item that is in an inactive state.

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.

5. A haptic feedback device, comprising:
-
a touch screen configured to sense a user'"'"'s input on the touch screen and display a graphical interface having a plurality of graphical objects, wherein the user'"'"'s input imparts a scrolling action among the plurality of graphical objects in the graphical interface; and at least one actuator configured to; output a first haptic effect based on the user'"'"'s input at an edge of a scrolling control region of the touch screen; and output a second haptic effect upon sensing the user'"'"'s input at another location on the scrolling control region. - View Dependent Claims (6, 7, 8)

9. A haptic feedback device, comprising:
-
a touch screen configured to; display a graphical interface having a plurality of graphical objects; sense a user'"'"'s input on the touch screen; and output a first signal based on the user'"'"'s input, wherein the first signal causes a scrolling action among the plurality of graphical objects in the graphical interface in response to the user'"'"'s input; 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 the first signal, the force being based on a second signal output by the computer.

10. A haptic feedback device, comprising:
-
a touch screen operative to output a first signal indicative 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 region, distinct from the first region, associated with a control functionality different from 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, said force being based on a second signal output by the computer. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33)
