VIBRATION SENSING TOUCH INPUT DEVICE |
摘要 |
The present invention provides a touch sensitive input device that uses vibrations due to touch impacts and/or frictional movement of a touch implement across a surface to determine information related to the touch, such as touch position. The present invention also provides for detecting lift-off events in such vibration sensing input devices. Lift-off detection can be accomplished by monitoring for a signal that indicates a sustained touch on the touch plate, and correlating a change in such a signal with a lift-off event. Signals indicating a sustained touch can include low frequency rumbles coupled into the touch plate via the touch implement, touch plate bending under the force of a sustained touch, and touch plate displacement under the force of a sustained touch. |
