1. An assembly, comprising:
- a touch screen;
a first element to cause the touch screen to vibrate at a predetermined frequency;
a first sensor proximate to a first portion of the touch screen for measuring vibration in the first portion of the touch screen;
a second sensor proximate to a second portion of the touch screen for measuring vibration in the second portion of the touch screen; and
position sensing logic for determining a position of a contact point on the touch screen based on the measured vibration in the first portion of the touch screen and the measured vibration in the second portion of the touch screen.

Abstract
An assembly may include a touch screen. A first element may be provided to cause the touch screen to vibrate at a predetermined frequency. A first sensor proximate to a first portion of the touch screen may measure vibration in the first portion of the touch screen. A second sensor proximate to a second portion of the touch screen may measure vibration in the second portion of the touch screen. Position sensing logic may determine a position of a contact point on the touch screen based on the measured vibration in the first portion of the touch screen and the measured vibration in the second portion of the touch screen.
