Abstract

An assembly for a terminal device comprises a frame, a touch-sensitive input panel operable to detect the location of a haptic user input, a member pivotally connected to the frame to define two or more pivot axes and supporting the panel at locations distinct from the pivot axes, the member being arranged in such a way that the length of a part of the member connecting points on the two pivot axes varies in response to the haptic user input, and such that the panel is displaced relative to the frame as said length varies, and a switch operable to detect displacement of said panel relative to the frame resulting from said haptic user input.

Claims

1. An assembly, comprising:

a frame;

a touch-sensitive input panel operable to detect the location of a haptic user input;

a member pivotally connected to the frame to define two or more pivot axes and to support the touch-sensitive input panel at locations distinct from the pivot axes, the member being arranged in such a way that the length of a part of the member connecting points on the two pivot axes varies in response to the haptic user input, and such that the touch-sensitive input panel is displaced relative to the frame as the length varies;

and a switch operable to detect displacement of the touch-sensitive input panel relative to the frame resulting from the haptic user input.

2. An assembly as claimed in claim 1, wherein the switch is coupled directly to the member so as to detect displacement of the member relative to the frame resulting from the haptic user input.

3. An assembly as claimed in claim 1, wherein the member comprises a plurality of rigid lever members linked to each other by a variable length connection.

4. An assembly as claimed in claim 1, wherein the member comprises a plurality of rigid components pivotally connected to the frame by a variable length connection.

5. An assembly as claimed in claim 3, wherein the variable length joint is a pin and slot joint.

6. An assembly as claimed in claim 3, wherein the member comprises two rigid components.

7. An assembly as claimed claim 6, wherein the two rigid components are substantially the same size.

8. An assembly as claimed in claim 1, wherein the member is resilient.

9. An assembly as claimed in claim 1, wherein the frame comprises

a base having four sidewalls to define a rectangular cavity, the member being pivotally connected to two opposing sidewalls of the four sidewalls.

10. An assembly as claimed in claim 1, wherein the switch is an electromechanical switch.

11. An assembly as claimed in claim 1, wherein the touch-sensitive input panel is a touchsensitive display panel.

12. An assembly comprising:

frame means;

touch-sensitive input means operable to detect the location of a haptic user input;

support means pivotally connected to the frame to define two or more pivot axes and supporting the input means at locations distinct from the pivot axes, the support means being arranged in such a way that the length of a part of the support means connecting points on the two pivot axes varies in response to the haptic user input, and such that the input means is displaced relative to the frame as the length varies, and

switch means operable to detect displacement of the input means relative to the frame resulting from the haptic user input.

13. An assembly as claimed in claim 12, wherein the switch means is coupled directly to the support means so as to detect displacement of the support means relative to the frame means resulting from the haptic user input.

14. An assembly as claimed in claim 12, wherein the support means comprises a plurality of rigid lever members linked to each other by a variable length connection.

15. An assembly as claimed in claim 12, wherein the support means comprises a plurality of rigid components pivotally connected to the frame means by a variable length connection.

16. An assembly as claimed in claim 14, wherein the variable length joint is a pin and slot joint.

17. An assembly as claimed in claim 14, wherein the support means comprises two rigid components.

18. An assembly as claimed in claim 17, wherein the two rigid components are substantially the same size.

19. An assembly as claimed in claim 12, wherein the support means is resilient.

20. An assembly as claimed in claim 12, wherein the frame means comprises a base means having four sidewalls to define a rectangular cavity, the support means being pivotally connected to two opposing sidewalls of the four sidewalls.
