TOUCH INTERFACE DEVICE HAVING AN ELECTROSTATIC MULTITOUCH SURFACE AND METHOD FOR CONTROLLING THE DEVICE
First Claim
1. A touch interface device comprising:
- a touch surface;
a first electrode coupled with the touch surface, the first electrode also configured to receive a first haptic actuation electric potential; and
a second electrode coupled with the touch surface and configured to receive a different, second haptic actuation electric potential having an opposite polarity than the first haptic actuation potential, wherein the first and second electrodes generate an electrostatic force that is imparted on one or more appendages of an operator that touches the touch surface above both the first electrode and the second electrode in order to generate a haptic effect.

Abstract
A touch interface device includes a touch surface, a first electrode, and a second electrode. The first electrode is coupled with the touch surface. The first electrode also configured to receive a first haptic actuation electric potential. The second electrode is coupled with the touch surface. The second electrode also is configured to receive a different, second haptic actuation electric potential having an opposite polarity than the first haptic actuation potential. The first and second electrodes generate an electrostatic force that is imparted on one or more appendages of an operator that touches the touch surface above both the first electrode and the second electrode in order to generate a haptic effect.

18. A touch interface device comprising:
-
a touch surface; and elongated electrodes coupled with the touch surface, the electrodes including a first electrode oriented along a first direction and a second electrode oriented along a different, second direction, the first electrode extending over the second electrode at a first intersection, wherein the first and second electrodes are configured to receive haptic actuation electric potentials of opposite polarities to generate an electrostatic force that is imparted on the one or more appendages of the operator that touch the touch surface above the first intersection. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26, 27)

28. A method comprising:
-
applying a first haptic actuation electric potential having a first polarity to a first electrode coupled with a touch surface of a touch interface device; and applying a second haptic actuation electric potential having a second polarity to a second electrode that is coupled with the touch surface, the second polarity of the second haptic actuation potential being opposite of the first polarity of the first haptic actuation potential, wherein the first and second haptic actuation potentials generate an electrostatic force that is imparted on one or more appendages of an operator that touch the touch surface above the first and second electrodes. - View Dependent Claims (29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39)
