20120286847 | TOUCH INTERFACE DEVICE AND METHOD FOR APPLYING CONTROLLABLE SHEAR FORCES TO A HUMAN APPENDAGE - A touch interface device includes a touch surface, an actuator, and an electrode. The actuator is coupled with the touch surface and is configured to move the touch surface in one or more directions. The electrode is coupled with the touch surface and is configured to impart a normal electrostatic force on one or more appendages of a human operator that engage the touch surface when an electric current is conveyed to the electrode. Movement of the touch surface by the actuator and the electrostatic force provided by the electrode are synchronized to control one or more of a magnitude or a direction of a shear force applied to the one or more appendages that engage the touch surface. | 11-15-2012 |
20120287068 | TOUCH INTERFACE DEVICE HAVING AN ELECTROSTATIC MULTITOUCH SURFACE AND METHOD FOR CONTROLLING THE DEVICE - 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. | 11-15-2012 |
