Abstract:

Input device haptics and pressure sensing techniques are described. An input device includes an outer surface, a pressure sensor and haptic feedback mechanism, and a pressure sensing and haptic feedback module. The outer surface is configured to receive an application of pressure by an object. The pressure sensor and haptic feedback mechanism has one or more piezos configured to detect and quantify an amount of the application of the pressure to the outer surface by the object, the one or more piezos configured to output a signal indicating the quantified amount of the pressure. The pressure sensing and haptic feedback module is configured to receive the signal from the one or more piezos indicating the quantified amount of the pressure and control the haptic feedback of the pressure sensor and haptic feedback mechanism.

Abstract:

Piezo-actuated structures are disclosed and haptic-enabled devices employing piezo-actuated structures are disclosed. One embodiment of a piezo-actuated structure comprises a non-traveling deformable layer, a backer structure that partitions the deformable layer into a set of substantially isolated haptic regions, a set of user sensors that are capable of detecting user interactions with at least one of the substantially isolated haptic regions. In another embodiment, a haptic-enabled device comprises a touch sensitive surface that comprises a deformable layer and set of substantially isolated haptic regions. The haptic-enabled device is capable of sending control signals to the isolated haptic region with which the user is interacting. The set of substantially isolated haptic regions may affect a number of special haptic experiences for the user of the device. Such special haptic experiences comprise a single hand (left and/or right) haptic event, a single user finger haptic event.
