Abstract

Multi-touch user interface interaction is described. In an embodiment, an object in a user interface (UI) is manipulated by a cursor and a representation of a plurality of digits of a user. At least one parameter, which comprises the cursor location in the UI, is used to determine that multi-touch input is to be provided to the object. Responsive to this, the relative movement of the digits is analyzed and the object manipulated accordingly. In another embodiment, an object in a UI is manipulated by a representation of a plurality of digits of a user. Movement of each digit by the user moves the corresponding representation in the UI, and the movement velocity of the representation is a non-linear function of the digit'"'"'s velocity. After determining that multi-touch input is to be provided to the object, the relative movement of the representations is analyzed and the object manipulated accordingly.

Claims

1. A computer-implemented method of manipulating an object displayed in a user interface on a display device, comprising:

receiving a first data sequence describing movement of a cursor control device operable by a user;

receiving a second data sequence describing movement of a plurality of digits of the user;

displaying in the user interface a cursor and a representation of at least one of the plurality of digits, and moving the cursor in the user interface in dependence on the first data sequence; and

determining from at least one parameter that multi-touch input is to be provided to the object, the parameter comprising the cursor location in the user interface, and, responsive thereto, analyzing the relative movement of the plurality of digits and manipulating the object in the user interface in dependence thereon.

2. A method according to claim 1, wherein the step of determining comprises determining that the cursor location is coincident with the location of at least a portion of the object in the user interface.

3. A method according to claim 1, wherein the method further comprises the step of receiving a third data sequence indicating an activation state of a user-operable control, and the at least one parameter further comprises the activation state from the third data sequence.

4. A method according to claim 3, wherein the step of determining further comprises detecting that the user-operable control is held in an activated state whilst the cursor location is coincident with the location of at least a portion of the object in the user interface.

5. A method according to claim 3, wherein the step of determining further comprises detecting that the user-operable control is changed to an activated state for at least a predefined time interval whilst the cursor location is coincident with the location of at least a portion of the object in the user interface.

6. A method according to claim 1, wherein the representation of at least one of the plurality of digits is displayed in proximity to a control point of the cursor.

7. A method according to claim 6, wherein the step of moving the cursor in the user interface in dependence on the first data sequence further comprises maintaining the location of the representation relative to the cursor.

8. A method according to claim 7, wherein the step of determining comprises determining that the cursor location is such that the representation location in the user interface is coincident with the location of at least a portion of the object in the user interface.

9. A method according to claim 1, wherein the cursor control device is a multi-touch mouse device arranged to sense movement of a base portion of the multi-touch mouse device over a supporting surface and sense movement of a plurality of digits of the user of the multi-touch mouse device relative to the base portion, and wherein the first data sequence describes the movement of the base portion, and the second data sequence describes movement of the digits of the user relative to the base portion.

10. A method according to claim 1, wherein the cursor control device is a mouse device, and the first data sequence describes the movement of the mouse device over a supporting surface.

11. A method according to claim 1, wherein the cursor control device is a touch pad, and the first data sequence describes the movement of a contact point of the user on the touch pad.

12. A method according to claim 1, wherein the cursor control device is an imaging device arranged to detect movement of a hand of the user.

13. A method according to claim 1, wherein the second data sequence is provided by a touch pad arranged to sense movement of a plurality of digits of the user over the touch pad.

14. A method according to claim 1, wherein the second data sequence is provided by an imaging device arranged to sense movement of a plurality of digits of the user.

15. A method according to claim 1, wherein the step of manipulating the object comprises at least one of:

rotating the object;

scaling the object; and

translating the object.

16. A computer-implemented method of manipulating an object displayed in a user interface on a display device, comprising:

receiving a data sequence describing movement of a plurality of digits of the user;

displaying in the user interface a representation of each of the plurality of digits;

processing the data sequence such that movement of each digit by the user moves the corresponding representation in the user interface, and the movement velocity of the representation is a non-linear function of the movement velocity of the corresponding digit; and

determining that multi-touch input is to be provided to the object, and, responsive thereto, analyzing the relative movement of each representation and manipulating the object in the user interface in dependence thereon.

17. A method according to claim 16, wherein the non-linear function is an acceleration function arranged to cause the movement velocity of the representation to be proportionately larger for a first movement velocity of a digit than for a second, smaller movement velocity of a digit.

18. A method according to claim 16, wherein the non-linear function is dependent on size of display device.

19. A method according to claim 16, further comprising the steps of:

receiving a further data sequence describing movement of a cursor control device operable by a user; and

displaying in the user interface a cursor, and moving the cursor in the user interface in dependence on the further data sequence, and

wherein the step of determining that multi-touch input is to be provided to the object is based on the cursor location in the user interface.

20. A computer system, comprising:

a display device;

an input interface arranged to receive a first and second data sequence from a multi-touch mouse device operable by a user, the first data sequence describing movement of a base portion of the multi-touch mouse device, and the second data sequence describing movement of a plurality of digits of the user of the multi-touch mouse device relative to the base portion; and

a processor arranged to display a user interface comprising an object on the display device, display in the user interface a cursor and a representation of each of the plurality of digits, move the cursor in the user interface in dependence on the first data sequence, determine from at least one parameter that multi-touch input is to be provided to the object, the parameter comprising the cursor location in the user interface, and, responsive thereto, analyze the relative movement of the plurality of digits and manipulate the object in the user interface in dependence thereon.
