Abstract

A user interface system for allowing users to initiate events comprises: a plurality of markers each having a marker identity; a plurality of portable readers each having a reader identity and arranged to read said marker identities from adjacent markers, and at least one base station arranged to communicate with said readers in a wireless manner, wherein at least one reader is provided with actuation means which when actuated by a user causes the reader identity of the reader and the marker identity of an adjacent marker to be transmitted by the reader to said base station, so as to cause, for at least one of said markers, said base station to initiate, directly or indirectly, an action which is at least partly determined by the reader identity of said reader.

Claims

1. A user interface system for allowing users to initiate events, the system comprising:

a plurality of markers each having a marker identity;

a plurality of portable readers each having a reader identity and arranged to read said marker identities from adjacent markers, and

at least one base station arranged to communicate with said readers in a wireless manner,

wherein at least one reader is provided with actuation means which when actuated by a user causes the reader identity of the reader and the marker identity of an adjacent marker to be transmitted by the reader to said base station, so as to cause, for at least one of said markers, said base station to initiate, directly or indirectly, an action which is at least partly determined by the reader identity of said reader;

wherein when actuated by a user the transmission from at least some readers also includes a sequence number, which is incremented or decremented for each transmission; and

wherein said sequence number is also included in a confirmation transmitted from the base station to the reader that the marker and reader identities have been received.

2. A system as claimed in claim 1, wherein said action is also determined by the identity of said adjacent marker.

3. A system as claimed in claim 1, wherein at least some of said readers are associated with different users, in order to allow said action to be customized for different users.

4. A system as claimed in claim 1, wherein at least one reader provided with said actuation means is also provided with reading means for reading the identity of an adjacent marker, and said reading means is arranged to operate in a low power mode until actuation of said actuation means, and to switch to an operational mode following actuation of said actuation means.

5. A system as claimed in claim 4, wherein said reading means returns to said low power state after reading the identity of an adjacent marker.

6. A system as claimed in claim 5, wherein said reading means returns to said low power state before transmission of said identity of an adjacent marker and the reader identity to a base station.

7. A system as claimed in claim 1, wherein some or all of said portable readers are provided without any screen for displaying information to the user.

8. A system as claimed in claim 1, wherein some or all of said portable readers have a maximum dimension which is not greater than 4, 6 or 8 cm.

9. A system as claimed in claim 1, wherein said action takes place in the vicinity of said adjacent marker.

10. A system as claimed in claim 1, wherein said action is carried out by a device which is not part of, and not physically connected to, said reader.

11. A system as claimed in claim 1, wherein said base station is arranged to transmit to at least one reader a confirmation that the marker and reader identities have been received.

12. A system as claimed in claim 11, wherein said confirmation includes information relating to said action.

13. A system as claimed in claim 11, wherein at least one reader is arranged to provide a perceivable indication of said confirmation to the user.

14. A system as claimed in claim 11, wherein said at least one reader remains connected to said base station, in a networking sense, only until said confirmation has been received, or shortly thereafter.

15. A system as claimed in claim 1, wherein transmissions between at least some readers and base stations include a checksum.

16. A system as claimed in claim 1, which further comprises a monitoring system to which the or each base station is connected, and which contains a database of actions corresponding to each pair of reader and marker identities.

17. A system as claimed in claim 16, wherein the monitoring system is a CORBA object running on a computer connected to the internet.

18. A system as claimed in claim 1, wherein actuation of a reader adjacent to two markers within a predetermined period of time causes one or more actions which result in an association being formed between two hardware devices associated with said two markers respectively.

19. A system as claimed claim 1, wherein actuation of a first reader adjacent a given marker prevents the successful actuation of a further reader adjacent the same marker for a predetermined period of time, or until a particular event has occurred.

20. A system as claimed in claim 19, wherein said particular event is a subsequent actuation of said first reader adjacent said given marker.

21. A system as claimed in claim 1, wherein the or each base station records the time of each reader transmission.

22. A system as claimed in claim 1, wherein transmissions between at least some readers and base stations are encrypted.

23. A system as claimed in claim 1, wherein at least one reader is provided with a miniaturized antenna in the form of a wound inductor, so that the range of the reader is about 1 cm or less.

24. A user interface system for allowing users to initiate events, the system comprising:

a plurality of markers each having a marker identity;

a plurality of portable readers each having a reader identity and arranged to read said marker identities from adjacent markers, and

at least one base station arranged to communicate with said readers in a wireless manner,

wherein at least one reader is provided with actuation means which when actuated by a user causes the reader identity of the reader and the marker identity of an adjacent marker to be transmitted by the reader to said base station, so as to cause, for at least one of said markers, said base station to initiate, directly or indirectly, an action which is at least partly determined by the reader identity of said reader;

further comprising a monitoring system to which the or each base station is connected, and which contains a database of actions corresponding to each pair of reader and marker identities; and

wherein the monitoring system is a CORBA object running on a computer connected to the internet.

25. A user interface system for allowing users to initiate events, the system comprising:

a plurality of markers each having a marker identity;

a plurality of portable readers each having a reader identity and arranged to read said marker identities from adjacent markers, and

at least one base station arranged to communicate with said readers in a wireless manner,

wherein at least one reader is provided with actuation means which when actuated by a user causes the reader identity of the reader and the marker identity of an adjacent marker to be transmitted by the reader to said base station, so as to cause, for at least one of said markers, said base station to initiate, directly or indirectly, an action which is at least partly determined by the reader identity of said reader;

wherein actuation of a first reader adjacent a given marker prevents the successful actuation of a further reader adjacent the same marker for a predetermined period of time, or until a particular event has occurred; and

wherein said particular event is a subsequent actuation of said first reader adjacent said given marker.
