Abstract

A graphic multi-user interface resolves multi-user conflicts. The interface includes a touch sensitive surface on which items, such as documents and images, can be displayed. The items have an associated state and policy. Touch samples are generated when users touch the touch sensitive surface. Each samples is identified with a particular user generating the of sample. The samples are associated with particular items. Touching items generates events. A decision with respect to a conflict affecting a next state of a particular item is made according to the events, the state and the policy.

Claims

1. A graphic multi-user interface for resolving conflicts, comprising:

a touch sensitive surface;

means for displaying a plurality of items on the touch sensitive surface;

means for generating a plurality of sequences of touch samples when a plurality of users simultaneously touch the touch sensitive surface, each sequence of samples being identified with a particular user generating the sequence of samples;

means for associating each sequence of samples with a particular item, the particular item having an associated state and a policy;

generating an event for each associated sequence of samples; and

means for determining a decision with respect to a conflict affecting a next state of the particular item according to the events from the plurality of users, the state and the policy.

2. The graphic multi-user interface of claim 1, in which the state of the item includes an owner, an access code, a size, an orientation, a color and a display location.

3. The graphic multi-user interface of claim 1, in which the particular item is active when a particular user is touching the particular item.

4. The graphic multi-user interface of claim 1, in which one particular user generates multiple sequences of sample for multiple touches.

5. The graphic multi-user interface of claim 1, in which each sample includes a user ID, a time, a location, an area and a signal intensity of the touch.

6. The graphic multi-user interface of claim 5, in which each sample includes a speed and trajectory of the touch.

7. The graphic multi-user interface of claim 1, in which the policy is global when the conflicts affects an application as a whole.

8. The graphic multi-user interface of claim 1, in which the policy is element when the conflicts affects a particular item.

9. The graphic multi-user interface of claim 1, in which the policy is privileged user depending on privilege levels of the plurality of users.

10. The graphic multi-user interface of claim 1, in which each user has an associated rank and the decision is based on the ranks of the plurality of users.

11. The graphic multi-user interface of claim 1, in which the policy is based on a votes made by the plurality of users.

12. The graphic multi-user interface of claim 1, in which the policy is release, and the decision is based on a last user touching the particular item.

13. The graphic multi-user interface of claim 1, in which the decision is based on an orientation of the particular item.

14. The graphic multi-user interface of claim 1, in which the decision is based on a location of the particular item.

15. The graphic multi-user interface of claim 1, in which the decision is based on a size of the particular item.

16. The graphic multi-user interface of claim 1, further comprising:

means for displaying an explanatory message related to the decision.

17. The graphic multi-user interface of claim 1, in which the decision is based on a speed of the events.

18. The graphic multi-user interface of claim 1, in which the decision is based on an area of the events.

19. The graphic multi-user interface of claim 1, in which the decision is based on a signal intensity of the events.

20. The graphic multi-user interface of claim 1, in which the decision tears the particular item into multiple parts.

21. The graphic multi-user interface of claim 1, in which the decision duplicates the particular item.

22. The graphic multi-user interface of claim 7, in which the application has a global state, and further comprising:

allowing a change to the global state only if all times are inactive, no users are touching the touch sensitive surface or any of the plurality of items.

23. A method for resolving conflicts with a graphic multi-user interface, comprising:

displaying a plurality of items on a touch sensitive surface;

generating a plurality of sequences of touch samples when a plurality of users simultaneously touch the touch sensitive surface, each sequence of samples being identified with a particular user generating the sequence of samples;

associating each sequence of samples with a particular item, the particular item having an associated state and a policy;

generating an event for each associated sequence of samples; and

determining a decision with respect to a conflict affecting a next state of the particular item according to the events from the plurality of users, the state and the policy.
