Abstract

A tactile device comprising a tactile device and a feedback mechanism operable with a sensing surface to receive a force input from a user and transfer that force input to a force sensing element. The tactile device is configured to allow the user to touch the tactile device and register an input force with the force sensing element. The tactile device is also operable with the feedback mechanism to provide feedback to the user that the force input from the user has been registered with the force sensing element.

Claims

1. A tactile feedback device operable with a force-based input device comprising:

a receiving component to receive a force input from a user that is operable to displace and transfer the received force to a sensing surface of said force-based input device; and

a feedback mechanism to provide tactile feedback to the user to ensure proper and complete force transfer and registration.

2. The tactile feedback device of claim 1, wherein the receiving component is configured to contact and be supported about the sensing surface.

3. The tactile feedback device of claim 1, wherein the feedback mechanism is a spring.

4. The tactile feedback device of claim 1, wherein the receiving component comprises a head component and a base component.

5. The tactile feedback device of claim 4, wherein the head component comprises a top surface where the user inputs a force and a recessed area on a surface opposite the top surface that is configured to allow the base component to nest within the recessed area, and that is configured to couple a pin within the recessed area, wherein the pin pivotally couples the head component to the base component to enable the head component to move relative to the base component, wherein the recessed area is configured to receive the spring between the base component and the head component to provide the tactile feedback.

6. The tactile feedback device of claim 4, wherein the feedback mechanism is supported about a lower surface of the receiving component and rests directly on the sensing surface causing the force to be transferred to the sensing surface directly from the feedback mechanism, and further wherein the head component is configured to pivotally couple with the base component and to directly receive the applied force.

7. The tactile feedback device of claim 6, wherein the head component further includes a recessed area that is configured to receive and maintain the feedback mechanism in a position relative to the sensing surface and head component.

8. The tactile feedback device of claim 1, wherein the receiving component is coupled to the feedback mechanism, and wherein the receiving component comprises a compliant member having a head component and a base component, wherein the compliant member facilitates flexing of the receiving component.

9. The tactile feedback device of claim 8, wherein the base component is inseparably coupled to the head component through a neck that flexes in response to said force input.

10. The tactile feedback device of claim 9, wherein the neck extends from the head component into the hollow area and centers the base component in relation to the head component and positions the base component slightly above the hollow area.

11. The tactile feedback device of claim 9, wherein the neck comprises an aperture configured to support the feedback mechanism and to facilitate the operation of the feedback mechanism when the force is applied to the head component.

12. The tactile feedback device of claim 11 wherein the base component further comprises a bottom surface that is configured to relate to the sensing surface and that locates the tactile feedback device above the sensing surface.

13. The tactile feedback device of claim 12, wherein the base component is attached to the sensing surface with an adhesive material.

14. The tactile feedback device of claim 12, wherein the base component is attached to the sensing surface with a fastener.

15. The tactile feedback device of claim 11, wherein the feedback mechanism is configured as a separate component substantially the same size as the aperture and configured to produce a tactile sensation when the neck flexes.

16. An input system comprising:

a touch-based input device comprising a sensing element having a sensing surface, wherein the sensing element is configured to receive and register a force input from a user, and to output a signal to determine the location of the applied force; and

a tactile feedback device comprising a receiving component and a feedback mechanism, said tactile feedback device operates to provide said force input and tactile feedback to said user.

17. The input system of claim 16, further comprising a screen to visually illustrate a result of the applied force about the tactile feedback device.

18. The input system of claim 16, wherein the output signal is sent to a signal processor for determining a location and/or a magnitude of said force input about said sensing element.

19. A method for receiving tactile feedback from a tactile feedback device comprising:

providing a tactile feedback device operable with a force-based input device comprising

a receiving component to receive a force input from a user that is operable to displace and transfer the received force to a sensing surface of said force-based input device, and

a feedback mechanism to provide tactile feedback to the user to ensure proper and complete force transfer and registration;

applying a force to the receiving component; and

receiving tactile feedback from the feedback mechanism.

20. The method of claim 19, further comprising causing the receiving component, configured as a compliant member, to bend in response to said force input.

21. The method of claim 19, further comprising causing the receiving component, configured as a pivoting member, to pivot in response to said force input.
