Haptic interface for laptop computers and other portable devices
First Claim
1. A haptic feedback touch control for inputting signals to a computer and for outputting forces to a user of the touch control, the touch control comprising:
- a touch input device including an approximately planar touch surface operative to provide;
1) a position signal based on a location on said touch surface which said user contacts, said position signal representing said location in two dimensions, and
2) a selection signal indicating a user selection, wherein said computer receives position information derived from said position signal and receives said selection signal; and
at least one actuator coupled to said touch input device, said actuator outputting a force on said touch input device to laterally move said touch input device approximately parallel to a surface of said touch input device to provide a haptic sensation to said user contacting said touch surface, wherein said actuator outputs said force in the absence of said selection signal, based on force information output by said computer.

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.

34. A method for providing haptic feedback to a touch input device that provides input to a computer device, said computer device implementing a graphical environment, the method comprising:
-
providing said touch input device that is contacted by a user, said touch input device including at least one sensor for determining a location of said contact on a planar surface of said touch input device by said user and providing said computer device with;
1) a position signal indicating said location, and
2) a selection signal indicating a user selection; andproviding an actuator coupled to said touch input device, said actuator receiving control signals derived from force information output by said computer device, wherein said force information causes said actuator to output a force on said touch input device in the absence of said selection signal, said force being correlated with an interaction occurring in said graphical environment between said cursor and a different graphical object, wherein said force causes said touch input device to translate laterally and approximately parallel to said planar surface of said touch input device. - View Dependent Claims (35, 36, 37, 38, 39, 40)
