Problems solved by technology

However, mechanically incorporating and installing these actuators into consumer products is often cumbersome
In addition, monolithic piezoceramics are often very brittle and can crack if the electronic device incorporating the ceramic is dropped or otherwise subjected to similar forces or stresses
Incorporating monolithic piezoelectric ceramics into commercial products can often be difficult

Embodiment Construction

[0027] This disclosure describes embodiments of haptic devices that include haptic feedback actuators that communicate via a user interface, human-machine interface, or other feature of a user device on or within which the actuator is located. section, to apply haptic effects to the user. More specifically, embodiments of the haptic devices described herein may be configured to apply haptic effects to a touch-sensitive surface of a user device. In some embodiments, the touch-sensitive surface is part of a display device that may include both visual output mechanisms and touch-sensitive input mechanisms. Thus, haptic feedback can be applied to user devices such as electronic handheld devices, thereby providing users with a rich sensory experience.

[0028] This disclosure describes the use of "composite piezoelectric materials" to provide haptic feedback as opposed to the use of monolithic piezoelectric actuators. Haptic feedback may also be referred to as haptic effects, tac...

Abstract

A haptic device includes a substantially transparent composite piezoelectric cell configured to measure a deformation of a surface of the cell and to provide a haptic feedback effect as a result of the deformation.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Provisional Patent Application No. 61 / 327,625, filed April 23, 2010, the contents of which are hereby incorporated by reference in their entirety. technical field [0003] The present invention relates to a haptic device comprising a transparent composite piezoelectric combined touch sensor and haptic actuator. Background technique [0004] Manufacturers of electronic devices strive to generate rich interfaces for users. Conventional electronic devices typically provide visual and / or audible feedback to convey information to the user. In some cases, kinesthetic feedback (such as active force and resistance feedback) and / or tactile feedback (such as vibration, texture, and heat) are also provided to the user. In general, kinesthetic feedback and tactile feedback are collectively referred to as "haptic feedback" or "haptic effects." Haptic feedback is useful where it provides cue...
