Haptic feedback for touchpads and other touch controls
First Claim
1. A method of outputting localized haptic effects comprising:
- selecting a housing having a touch screen coupled thereto;
coupling a plurality of actuators to the housing; and
outputting an activating signal to two or more of the actuators to produce a haptic effect of a desired magnitude, wherein the two activated actuators each output respective haptic effects of different magnitudes.

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.

2. A haptic feedback device comprising:
-
a user interface device configured to display a graphical object to a user via a touch screen, wherein the graphical object is programmed to have a first state or a second state; and
an actuator coupled to the touch screen and configured to impart a haptic effect to the haptic feedback device when a user'"'"'s input on the touch screen selects the graphical object only when in the first state. - View Dependent Claims (3)

4. A haptic feedback device comprising:
-
a housing;
one or more portions separately movable relative to the housing; and
an actuator configured to impart a first haptic force to one of the separately movable portions and a second haptic force to another of the separately movable portions, or to the housing.

5. A handheld communication device comprising:
-
a housing having a button thereon;
a first sensor coupled to the button, wherein the first sensor outputs a first sensor signal upon the button being depressed;
a touch screen coupled to the housing;
a second sensor coupled to the touch screen, wherein the second sensor outputs a second sensor upon the user providing an input to the touch screen;
a processor coupled to the first and second sensors, wherein the processor outputs a predetermined signal to perform a specific task by the communication device upon receiving the first and second signals.

6. A method of scrolling on an electronic device, the method comprising:
-
selecting a touch screen configured to display a graphical interface having a plurality of graphical objects;
sensing a user'"'"'s input with the touch screen, wherein the user'"'"'s input imparts a scrolling action among the plurality of graphical objects in the graphical interface;
outputting a first haptic effect upon sensing the user'"'"'s input at an edge of a scrolling control region of the touch screen; and
outputting a second haptic effect upon sensing the user'"'"'s input at another location on the scrolling control region.
