1. A device that accepts an input to a computing device, comprising:
- a first layer having a translucent cover;
a second layer having a plurality of surfaces, said surfaces being one of a capacitive or resistive surface and being constructed using a translucent and conductive material;
a third layer having a light-emitting material which generates light responsive to said input, said light-emitting material generating light that persists for a period of time after one of a user'"'"'s finger and thumb has been positioned at a location on the top side of said first layer, said light being generated only in an area proximate to said location; and
a fourth layer which generates light of a different color than light generated by said third layer.

Abstract
A device used to accept an operator input to a computing device is disclosed. The device includes a first layer that includes a translucent, two-dimensional cover. Additionally included is a second layer in which a plurality of surfaces is constructed using a translucent and conductive material. The device further includes a third layer that employs a light-emitting material that generates light in response to the operator input.

14. A device that accepts an input to a computing device, comprising:
-
a first layer having a translucent cover;
a second layer having a plurality of surfaces, said surfaces being one of a capacitive or resistive surface and being constructed using a translucent and conductive material;
a third layer having a light-emitting material which generates light responsive to said input, said light-emitting layer generating light that persists for a period of time after one of a user'"'"'s finger and thumb has been positioned at a location on the top side of said first layer, said light being generated in areas other than an area proximate to said location; and
a fourth layer for generating light of a different color than light generated by said third layer.

15. A device that accepts an input to a computing device, comprising:
-
a first layer having a translucent cover;
a second layer having a plurality of surfaces, said surfaces being one of a capacitive or resistive surface and being constructed using a translucent and conductive material;
a third layer having a light-emitted material which generates light responsive to said input; and
a fourth layer which generates light of a different color than light generated by said third layer, said generated light presenting the appearance of soft keys.

16. A computing device that makes use of a touch pad to provide feedback to a user, said feedback being indicative of an operating mode of at least one input device used by said computing device, comprising:
-
a first layer which includes a substantially rigid, transparent surface;
a second layer which includes a plurality of surfaces proximate with said first layer, said plurality of surfaces being constructed of a transparent and conductive material;
a third layer which includes a light-emitting layer, said third layer generating light in response to an operator input and notifying said user that said operator input is required, wherein said light-emitting layer is arranged to present a particular symbol to said user; and
an illumination controller coupled to said third layer for bringing about said light generated in response to said operator input. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27)
