Accelerometer module for use with a touch sensitive device
First Claim
1. A method of sensing acceleration, comprising:
- disposing a deformable member adjacent a touch screen surface;
directing an acceleration to push the deformable member against the touch screen surface to cause a change in a degree of elastic deformation of the deformable member; and
sensing a change in a contact area between the deformable member and the touch screen surface as a result of the change in the degree of elastic deformation.

Abstract
An accelerometer module for use with a touch sensor on a device, a method of detecting acceleration using a touch sensor, and a computer program product for receiving the touch sensor data and producing output representative of acceleration. The accelerometer module provides a device with a touch sensor, such as a mobile phone, with the ability to sense acceleration, orientation, or both. The accelerometer module may sense acceleration along a single axis or multiple axis. Sensing acceleration along three axis may be useful for producing a handheld game controller or for providing input to many other applications. The accelerometer module applies a force against a deformable member to change the contact area between the deformable member and the touch sensor, wherein the contact area is a function of the amount of applied acceleration.
