Haptic feedback system
First Claim
1. A haptic feedback device comprising:
- a plurality of controllable nodes disposed between a first surface and a second surface, the controllable nodes being configurable to change between transmission states and non-transmission states so as to pass or block a haptic signal received from the second surface and provide a localized haptic response at the first surface when two or more of the controllable nodes are configured to pass the received haptic signal, the plurality of controllable nodes being individually configurable to combine the haptic signal at one or more of a plurality of selectable regions to provide the localized haptic response.

Abstract
Localized haptic feedback at discrete locations or regions of a surface is disclosed. Controllable haptic transmission nodes can be selectively controlled to transmit a haptic feedback signal to a surface. The nodes can be controlled between a first state that transmits the haptic feedback signal to the surface and a second state that dampens or prevents the haptic feedback signal to the surface. The nodes can be located around the perimeter of the surface, where each node can be associated with a particular location or region of the surface and can provide haptic feedback to that particular location or region when the node is selected. A touch surface of a touch sensitive device is an exemplary surface for using localized haptic feedback.

15. A touch sensitive device with a haptic system, comprising:
-
a surface; a sensor arrangement configured to detect a location of an object in close proximity to the surface; a haptic signal generator configured to produce a haptic signal when an object is detected; and a plurality of haptic transmission nodes coupled between the surface and the haptic signal generator and positioned at different locations relative to the surface, the haptic transmission nodes being configurable to receive the haptic signal from the haptic signal generator, and to change states in order to selectively pass or block transmission of the received haptic signal and provide a localized haptic response at the surface when two or more of the plurality of haptic transmission nodes are configured to pass the received haptic signal, the plurality of haptic transmission nodes being individually configurable to combine the haptic signal at one or more of a plurality of selectable regions to provide the localized haptic response. - View Dependent Claims (16, 17, 18, 19, 20, 21)

22. A method for providing a haptic feedback signal to a surface, comprising:
-
identifying two or more haptic transmission nodes from a plurality of individually configurable haptic transmission nodes, the two or more haptic transmission nodes corresponding to one or more of a plurality of selectable locations on the surface; placing the identified two or more haptic transmission nodes into a transmission state; generating a haptic feedback signal outside the identified two or more haptic transmission nodes and applying the haptic feedback signal to the identified two or more haptic transmission nodes; and transmitting the generated haptic feedback signal via the identified two or more haptic transmission nodes and combining the haptic signal at the one or more selectable locations on the surface to provide a localized haptic response. - View Dependent Claims (23, 24, 25, 26)
