Key system for a communication device
First Claim
1. A key activation system for use in a communication device, comprising:
- a key having a plurality of selectable values associated with it;
an activation mechanism associated with said key, said activation mechanism having a first and a second activation conditions;
a first feedback system associated with said activation mechanism, providing a first feedback sense on said device, said first feedback sense selected from one of a motion, visual and audible signal when said activation mechanism has triggered said first activation condition depending on which value of said plurality of values is currently associated with said key; and
a second feedback system providing a second feedback sense on said device, said second feedback sense indicating when said key has triggered said second activation condition, said second feedback system utilizing at least one of a deflection and compression of a component on said key,wherein said first activation condition is triggered before said second activation condition when said activation mechanism is initially engaged.

Abstract
A key activation system for use in a handheld communication device is provided. The system comprises an activation mechanism associated with a key in the system, a first feedback system and a second feedback system. The activation mechanism is associated with the key activation system and provides a first feedback sense when the activation mechanism has triggered the first activation condition. The second feedback system provides a second feedback sense indicating when the key triggers the second activation condition. In the system, the second feedback system operates independently from the activation mechanism and the first activation condition is triggered before the second activation condition when the activation mechanism is initially engaged. An activation mechanism may be centrally located for a set of keys.

7. A keypad system for use in a communication device, comprising:
-
a plurality of keys, each key of said plurality of keys having at least a first and a second activation conditions and having a plurality of values associated with it; a central activation sensor to detect any of said first and second activation conditions from activation of any key of said plurality of keys; and a first feedback system associated with said central activation sensor, said first feedback system providing a first feedback sense selected from one of a motion, visual and audible signal when said any key has triggered said first activation condition depending on which value of said plurality of values is currently associated with said any key; and a second feedback system associated with said central activation sensor, said second feedback system providing a second feedback sense generated to indicate when said any key has triggered said second activation condition, said second feedback system utilizing at least one of a deflection and compression of a component on said key, wherein said first activation condition is triggered before said second activation condition when said central activation sensor is initially engaged by activation of said any key. - View Dependent Claims (8, 9, 10, 11)

12. A method for providing a feedback during activation of a key for use in a communication device, comprising:
-
associating said key with a plurality of selectable values; providing said key with a first and a second activation conditions; providing a first feedback sense selected from one of a motion, visual and audible signal when activation of said key has activated said first activation condition depending on which value of said plurality of values is currently associated with said key; and providing a second feedback sense to indicate when said key has triggered said second activation condition, said second feedback system utilizing at least one of a deflection and compression of a component on said key, wherein said first activation condition is triggered before said second activation condition when said activation mechanism is initially engaged. - View Dependent Claims (13, 14, 15, 16)
