Handheld electronic device having keyboard that provides two-dimensional navigation, and associated method
First Claim
1. A method of enabling navigation on a display of a handheld electronic device, said display having an X-Y coordinate system for identifying locations thereon, said handheld electronic device having a keyboard having a first plurality of keys, each of said keys having an assigned first X coordinate and an assigned first Y coordinate, the method comprising:
- determining a second X coordinate and a second Y coordinate in said X-Y coordinate system based on a force applied to each of a second plurality of said keys and on the first X coordinate and the first Y coordinate of each of said second plurality of said keys; and
moving a visual indicator displayed on said display to a particular location on said display identified by said second X coordinate and said second Y coordinate.

Abstract
A method of enabling navigation on a display of a handheld electronic device. The display has an X-Y coordinate system for identifying particular locations thereon. In addition, the handheld electronic device has a keyboard having a first plurality of keys, each of which has an assigned first X coordinate and an assigned first Y coordinate. The method includes determining a second X coordinate and a second Y coordinate in the X-Y coordinate system based on: (i) a force applied to each of a second plurality of the keys, and (ii) the first X coordinate and the first Y coordinate of each of the second plurality of the keys, and moving a visual indicator to a particular location on the display identified by the second X coordinate and the second Y coordinate. Also, a handheld electronic device that implements the method, and a key assembly that may utilized therein.

14. A key assembly for a handheld electronic device, comprising:
-
a key moveably mounted within a housing of said handheld electronic device, said key having a top portion extending outwardly form said housing and a bottom portion disposed within said housing;
a collapsible dome mounted on a circuit board within said housing, said collapsible dome, when fully collapsed, completing a circuit provided on said circuit board; and
a transducing element located between said bottom portion of said key and a top surface of said collapsible dome, said transducing element converting a force applied thereto by said bottom portion of said key into a voltage proportional to said force. - View Dependent Claims (15, 16, 17)
