HAPTIC FEEDBACK SYSTEM
First Claim
1. A haptic feedback device comprising:
- a plurality of controllable nodes disposed between a first and a second surface, the controllable nodes being configured to change between transmission states and a non-transmission states so as to provide a localized haptic response in discrete regions of the first surface when the second surface is powered with a haptic signal.

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.

9. The haptic feedback device further comprising a haptic controller that receives a signal indicating a location of an object near or at the first surface, and that selectively controls the controllable nodes to produce the localized haptic response at the location of the object relative to the first surface.

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 positioned at different locations relative to the surface, the haptic transmission nodes being configured to receive the haptic signal from the haptic signal generator, and to change states in order control the transmission of the haptic signal to the surface, the haptic transmission nodes associated with the location of the object substantially transmitting the haptic signal to the surface, the haptic transmission nodes not associated with the location of the object substantially not transmitting the haptic signal to the surface. - View Dependent Claims (16, 17, 18, 19, 20, 21)

22. A method for providing a haptic feedback signal to an input surface, comprising:
-
identifying at least one haptic transmission node corresponding to a location of an input on the input surface; placing the identified haptic transmission node into a transmission state; generating a haptic feedback signal; and transmitting the generated haptic feedback signal via the at least one identified haptic transmission node to the location of the input on the input surface. - View Dependent Claims (23, 24, 25, 26)
