Abstract

Method with which users (1) enter instructions, in which said instructions are entered with sequences of voluntary movements of eye parts, the sequence required for entering a certain instruction being individual for each user.

Claims

1. Method with which users enter instructions, said instructions being entered with sequences of several voluntary movements of eye parts, wherein the individual sequence required for entering a certain instruction is entered by every user in a learning phase and repeated for entering this instruction, so that the sequence is individual for each user.

2. The method of claim 1, wherein said sequence comprises a plurality of viewing directions.

3. The method of claim 2, wherein an image is reproduced to said user and wherein said viewing directions correspond to predefined image parts.

4. The method of claim 3, wherein said image is three-dimensional.

5. The method of claim 3, wherein said image parts correspond to a virtual keyboard.

6. The method of claim 3, wherein said image is represented on a screen.

7. The method of claim 3, wherein said image is reproduced with a VRD device.

8. The method of claim 1, wherein said sequence comprises different focussing distances.

9. The method of claim 1, wherein said sequence comprises at least one blink.

10. The method of claim 1, wherein said sequence comprises at least one voluntary squinting eye movement.

11. The method of claim 1, wherein said sequence is converted as digital code.

12. The method of claim 11, wherein said digital code is signed electronically.

13. The method of claim 11, wherein said code is signed electronically with said user'"'"'s private key.

14. The method of claim 11, wherein said code is signed with the user'"'"'s biometric characteristics.

15. The method of claim 14, wherein said biometric characteristics of the user comprise eye characteristics.

16. The method of claim 15, wherein said biometric characteristics of the user comprise eye characteristics of eye parts of both eyes.

17. The method of claim 1, wherein a parameter dependent on the body temperature is measured and is linked with said sequence.

18. The method of claim 1, wherein a parameter dependent on the warming of the retina is measured and linked with said sequence.

19. The method of claim 1, wherein the reaction of the iris to light variations is measured and linked as parameter with said sequence.

20. The method of claim 1, wherein said sequence is determined through a portable terminal, said sequence being transmitted through a mobile radio part in said terminal over a mobile radio network to a remote server.

21. The method of claim 20, wherein said server is administered by a service provider and wherein the connection between said mobile radio part and said server is encrypted end-to-end.

22. The method of claim 21, wherein said sequence is compared in said server with a sequence stored by the user in advance, and wherein said instruction is only then carried out when the entered and the stored sequences correspond.

23. The method of claim 1, wherein a plurality of different individual sequences is provided for each user, each sequence corresponding to another instruction.

24. The method of claim 1, wherein said sequence is determined through a portable terminal and is compared with a sequence stored in this terminal.

25. Terminal, comprising

means for determining the sequences of voluntary movements of eye parts,

means for encoding and encrypting said sequences,

and means for sending said encoded sequences over a mobile radio network to a remote server.

26. Server in a communication network, having a database in which a plurality of individual sequences of voluntary movements of eye parts are contained, each sequence corresponding to a certain instruction of a certain user.
