Abstract

An exemplary embodiment concerns a touch screen arranged to determine when touched by a user'"'"'s screen-engagement member and further arranged to identify an identifying characteristic of the engagement member and so as to differentiate between different screen-engagement members and wherein at least one aspect of subsequent operation of the screen is responsive to the identification of the member.

Claims

1. A touch screen arranged to determine when touched by a user'"'"'s screen-engagement member and further arranged to identify an identifying characteristic of the said engagement member and so as to differentiate between different screen-engagement members and wherein at least one aspect of subsequent operation of the screen is responsive to the identification of the said member.

2. A touch screen as claimed in claim 1, and comprising an interface device for any one or more of a hand held device, portable device, remote device or system.

3. A touch screen as claimed in claim 1, and arranged for use in a multi-user environment comprising a multi-user device/apparatus/system.

4. A touch screen as claimed in claim 1, and arranged for engagement with the user'"'"'s screen-engagement member in the form of a user'"'"'s finger and/or thumb.

5. A touch screen as claimed in claim 4 wherein the said identifying characteristic of the said screen engagement member comprises biometric data.

6. A touch screen as claimed in claim 5 wherein the identifying characteristic comprises a user'"'"'s finger/thumb print.

7. A touch screen as claimed in claim 1 wherein the screen-engagement member comprises a screen contact device including a unit that serves to provide said identifying characteristic.

8. A touch screen as claimed in claim 7, wherein the said unit that serves to provide said identifying characteristic comprises an electronic device.

9. A touch screen as claimed in claim 8, wherein the electronic device comprises an electronic tag.

10. A touch screen as claimed in claim 7, wherein the screen-engagement member comprises a screen-engagement stylus.

11. A touch screen as claimed in claim 1, wherein the said identifying characteristic serves to identify the screen-engagement member.

12. A touch screen as claimed in claim 1, wherein the said identifying characteristic serves to identify the screen-user.

13. A touch screen as claimed in claim 1, wherein the at least one aspect of subsequent operation comprises display options of the screen and the provision of a predetermined image field.

14. A touch screen as claimed in claim 13, wherein the said predetermined image field includes at least one region for identifying an identifying characteristic of the screen-engagement member for differentiating between different screen-engagement members.

15. A touch screen as claimed in claim 14 wherein the said at least one region comprises at least one trigger point for initiating a further response of the touch screen.

16. A touch screen as claimed in claim 14 in which the said image field and the said at least one region exhibit a menu-tree structure.

17. A touch screen as claimed in claim 1, wherein the said at least one aspect of subsequent operation can include functional options and/or functional control options of the screen or device/apparatus/system interfacing thereto.

18. A touch screen as claimed in claim 1, wherein the said at least one aspect includes user access to the screen and/or to a device/apparatus/system interfacing thereto.

19. A touch screen as defined in claim 18 wherein the at least one aspect of subsequent operation relates to user settings and/or privileges within the screen and/or a device/apparatus/system interfacing thereto.

20. A touch screen as claimed in claim 1 and further arranged to capture identifying characteristics of one or more screen-engagement members for subsequent use in determining the said operation.

21. A multi-user electronic control system including at least one touch screen as defined in claim 1.

22. A method of controlling at least one aspect of operation of a touch screen including determining when touched by a user'"'"'s screen engagement member and including the steps of identifying an identifying characteristic of the said screen engagement member so as to differentiate between different screen engagement members, and wherein the said at least one aspect is controlled responsive to identification of the said screen engagement member.
