First Claim
Patent Images
1. A coordinate input device comprising:
- a substrate; and
a plurality of sensing layers formed over the substrate, the sensing layers having a recognizable shape and comprising;
at least first and second layers that sense movement of an operating member; and
at least a third layer for sensing a force applied by the operating member, wherein the recognizable shape provides tactile feedback to the operating member of the position of the operating member on the coordinate input device.

Abstract
A force and movement sensitive non-mechanical coordinate input device (100, 200) provides tactile feedback to a finger (110) of the finger'"'"'s position on the coordinate input device (100, 200). The coordinate input device (100, 200) includes a plurality of sensing layers (104) having a recognizable shape (112, 212). The sensing layers (104) include at least first and second layers (302, 306) that sense movement of a finger (110), at least a third layer (204) for sensing a force applied by the finger (110), wherein the recognizable shape (112, 212) provides tactile feedback to the finger (110) of the position of the finger (110) on the coordinate input device (100, 200).

8. A coordinate input device comprising:
-
at least first and second layers that determine movement of an operating member by sensing a first electrical characteristic; and at least a third layer that determines a force applied by the operating member by sensing a second electrical characteristic, the at least first and second layers, and the at least third layer comprises a shape that provides tactile feedback to the operating member of the position of the operating member on the coordinate input device; and a controller coupled to the coordinate input device that senses a change in the first electrical characteristic when the operating member is moved on the coordinate input device and that senses a change in the second electrical characteristic when a force is applied to the coordinate input device by the operating member. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)

16. A coordinate input device comprising:
-
a substrate; at least first and second layers formed over the substrate that determine movement of an operating member by sensing a first electrical characteristic; and at least a third layer that determines a force applied by the operating member by sensing a second electrical characteristic, the at least first and second layers, and the at least third layers comprise a convex shape that provides tactile feedback to the operating member of the position of the operating member on the coordinate input device; a controller coupled to the coordinate input device that senses a change in the first electrical characteristic when the operating member is moved on the coordinate input device and that senses a change in the second electrical characteristic when a force is applied to the coordinate input device by the operating member; and a device receiving an output from the controller and providing information in response to the movement and force applied by the operating member. - View Dependent Claims (17, 18, 19, 20)
