Haptic interface for touch screen embodiments
First Claim
1. A method of outputting haptic feedback comprising:
- sensing movement along a touch screen, wherein the movement is sensed with a sensor coupled to the touch screen;
comparing the sensed movement with a predetermined gesture;
recognizing a first symbol based on the comparison between the sensed movement and the predetermined gesture;
outputting a haptic feedback to the touch screen via an actuator coupled to the touch screen, wherein the actuator outputs the haptic feedback based on the recognized first symbol; and
outputting a second haptic feedback different from the haptic feedback based on a recognized second symbol, wherein the recognized second symbol is different than the recognized first symbol.

Abstract
A haptic feedback touch control used to provide input to a computer. A touch input device includes a planar touch surface that provides position information to a computer based on a location of user contact. The computer can position a cursor in a displayed graphical environment based at least in part on the position information, 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. The actuator can move the touchpad laterally, or a separate surface member can be actuated. A flat E-core actuator, piezoelectric actuator, or other types of actuators can be used to provide forces. The touch input device can include multiple different regions to control different computer functions.

7. A device, comprising:
-
a touch screen; an actuator coupled to the touch screen; a sensor coupled to the touch screen, the sensor configured to sense movement along the touch screen; and a processor coupled to the sensor, the processor configured to; compare the sensed movement with a predetermined gesture; recognize a first symbol based on the comparison between the sensed movement and the predetermined gesture; cause a haptic feedback to be output to the touch screen via the actuator, wherein the actuator outputs the haptic feedback based on the recognized first symbol; and cause a second haptic feedback to be output via the actuator, the second haptic feedback different from the haptic feedback based on a recognized second symbol, wherein the recognized second symbol is different than the recognized first symbol. - View Dependent Claims (8, 9, 10, 11, 12, 13)
