Abstract

A method of controlling a user interface comprising the steps of: detecting movement of a contact continuously between a first contact point at which contact is made and a second contact point at which contact is released; determining a state of a selection/de-selection mode of operation in dependence on: a line traced between the first contact point and the second contact point traversing one of more objects of an application layer; the first contact point not being co-incident with an object of the application layer; and the second contact point not being coincident with an object of the application layer.

Claims

1. A method of controlling a user interface comprising the steps of:

detecting movement of a contact continuously between a first contact point at which contact is made and a second contact point at which contact is released;

determining a state of a selection/de-selection mode of operation in dependence on;

a line traced between the first contact point and the second contact point traversing one of more objects of an application layer;

the first contact point not being co-incident with an object of the application layer; and

the second contact point not being coincident with an object of the application layer.

2. The method of claim 1 wherein the state of the mode is a selection mode if the one or more objects were unselected prior to the detecting step.

3. The method of claim 1 wherein the state of the mode is a de-selection mode if the one or more objects were selected prior to the detecting step.

4. The method of claim 1 wherein the state of the mode is a selection mode if a predetermined one or more objects were unselected prior to the detecting step.

5. The method of claim 1 wherein the state of the mode is a de-selection mode if a predetermined one of the one or more objects were selected prior to the detecting step.

6. The method of claim 1 wherein the one or more objects traversed are displayed in more than one application layer, being different to the application layer in which the first and second contact points are detected.

7. The method of claim 1 in which the first and second contact points are detected in the same application layer.

8. The method of claim 1 wherein the mode of operation is selection of objects for deletion.

9. The method of claim 8 wherein the deletion is activated automatically.

10. A computer program adapted, when run on a computer, to perform the method of claim 1.

11. A computer program product for storing computer program code which, when run on a computer, performs the method of claim 1.

12. A computer system adapted for controlling a user interface comprising:

means for detecting movement of a contact continuously between a first contact point at which contact is made and a second contact point at which contact is released;

means for determining a state of a selection/de-selection mode of operation in dependence on;

a line traced between the first contact point and the second contact point traversing one of more objects of an application layer;

the first contact point not being co-incident with an object of the application layer; and

the second contact point not being coincident with an object of the application layer.

13. The computer system of claim 12 wherein the state of the mode is a selection mode if the one or more objects were unselected prior to the detecting step.

14. The computer system of claim 12 further adapted such that the state of the mode is a de-selection mode if the one or more objects were selected prior to the detecting step.

15. The computer system of claim 12 further adapted such that the state of the mode is a selection mode if a predetermined one or more objects were unselected prior to the detecting step.

16. The computer system of claim 12 further adapted such that the state of the mode is a de-selection mode if a predetermined one of the one or more objects were selected prior to the detecting step.

17. The computer system of claim 12 further adapted such that the one or more objects traversed are displayed in more than one application layer, being different to the application layer in which the first and second contact points are detected.

18. The computer system of claim 12 further adapted such that the first and second contact points are detected in the same application layer.

19. The computer system of claim 12 further adapted such that the mode of operation is selection of objects for deletion.

20. The computer system of claim 19 further adapted such that the deletion is activated automatically.
