TOUCH SENSOR PAD USER INPUT DEVICE
First Claim
1. A method for determining input of a touch sensor pad by a plurality of fingers of a user, the method comprising:
- determining a home position on the touch sensor pad responsive to the plurality of fingers applying a first pressure to the touch sensor pad;
detecting a keystroke on the touch sensor pad responsive to a finger applying a second pressure to the touch sensor pad;
determining a relative position of the keystroke in reference to the home position of the finger responsive to detecting the keystroke; and
determining a value of the keystroke based on the relative position.

Abstract
A touch sensor pad may be utilized with an electronic device to perform different types of user input functions, such as typing, drawing, moving a cursor, etc. Regions of the touch sensor pad may correspond to keys of a keyboard. A user establishes a home position at a desired location of the touch sensor pad. When a user subsequently touches the touch sensor pad, the touch sensor pad determines a relative position of the touch in reference to the home position, and determines the value of the user input or keystroke based on the relative position. The value of the user input or the keystroke may then be processed by the controller.
