First Claim
Patent Images
1. A method of menu selection, comprising the steps of:
- calibrating a range of forces applied by a user on a force sensitive resistor selector key to a selective range of forces required for selecting a plurality of menu items; and
associating a selective subset from said range of forces by said user to each selection of a menu item.

Abstract
A method of menu selection is provided. An applied range of force by a user on a force sensitive resistor (112) selector key is calibrated (300) to a selective range of force for selecting a range of menu items. A variable press by that user is then associated (110) to a selection of a menu item.
