Abstract

The aggregation of multiple inputs in a touch-sensitive input device is disclosed. For example, one disclosed embodiment comprises receiving multiple inputs related to a virtual object, aggregating the inputs into an aggregated output, and providing the aggregated output to an application that controls the virtual object.

Claims

1. A method of aggregating multiple inputs in a touch-based input device, the method comprising:

receiving a first touch-based input related to a virtual object;

receiving a second touch-based input related to the virtual object;

aggregating the first touch-based input and the second touch-based input into an aggregated output; and

providing the aggregated output to an application that controls the virtual object.

2. The method of claim 1, wherein the aggregated output comprises information related to one or more of a position, a translation, a rotation and a scaling of the virtual object.

3. The method of claim 2, wherein the information related to a position comprises an average location of the first touch-based input and the second touch-based input.

4. The method of claim 2, wherein the information related to a translation comprises a translation of an average location of the first touch-based input and the second touch-based input.

5. The method of claim 2, wherein the information related to a rotation comprises a degree of rotation about an average location of the first touch-based input and the second touch-based input relative to a reference direction.

6. The method of claim 2, wherein aggregating the first touch-based input and the second touch-based input into an aggregated output comprises aggregating spatially non-overlapping touch-based inputs into an aggregated output.

7. The method of claim 1, wherein aggregating the first touch-based input and the second touch-based input into an aggregated output comprises aggregating temporally non-overlapping touch-based inputs into an aggregated output.

8. A computer-readable medium comprising instructions executable by a computing device to aggregate inputs from a multi-touch input device, the inputs being related to a virtual object, and the instructions being executable to perform a method comprising:

detecting a first touch-based input from a first manipulator;

passing the first touch-based input to an application;

passing the first touch-based input from the application to a manipulation processor;

detecting a second touch-based input from a second manipulator;

passing the second touch-based input to the application;

passing the second touch-based input from the application to the manipulation processor;

aggregating the first and second touch-based inputs into an aggregated output comprising information related to one or more of a position, a translation, a rotation and a scaling of the virtual object; and

passing additional inputs from the first manipulator and the second manipulator directly to the manipulation processor.

9. The computer-readable medium of claim 8, wherein the information related to a position comprises an average location of the first touch-based input and the second touch-based input.

10. The computer-readable medium of claim 8, wherein the information related to a translation comprises a translation of an average location of the first touch-based input and the second touch-based input.

11. The computer-readable medium of claim 8, wherein the information related to a rotation comprises a degree of rotation about an average location of the first touch-based input and the second touch-based input relative to a reference direction.

12. The computer-readable medium of claim 8, wherein the information related to a scaling is a scaling of the first touch-based input and the second touch-based input in relation to the average location.

13. The computer-readable medium of claim 8, wherein the information further comprises information regarding one or more of a wheel input, a virtual object zoom, a tap, and a touch-and-hold.

14. An apparatus comprising:

a touch-sensitive display configured to detect multiple touch inputs related to a virtual object displayed on the display; and

a controller in communication with the touch-sensitive display, the controller comprising a processor and memory containing computer-readable instructions executable to;

receive from the display a first touch-based input related to the virtual object from a first manipulator;

receive from the display a second touch-based input related to the virtual object from a second manipulator;

aggregate the first touch-based input and the second touch-based input into an aggregated output; and

provide the aggregated output to an application to adjust an appearance of the virtual object displayed on the display.

15. The apparatus of claim 14, wherein the aggregated output comprises information related to one or more of a position, a translation, a rotation and a scaling of the virtual object.

16. The apparatus of claim 15, wherein the information related to a position comprises an average location of the first touch-based input and the second touch-based input.

17. The apparatus of claim 15, wherein the information related to a translation comprises a translation of an average location of the first touch-based input and the second touch-based input.

18. The apparatus of claim 15, wherein the information related to a rotation comprises a degree of rotation about an average location of the first touch-based input and the second touch-based input relative to a reference direction.

19. The apparatus of claim 15, wherein the information related to a scaling comprises a scaling of the first touch-based input and the second touch-based input in relation to the average location.

20. The apparatus of claim 15, wherein any of the translation, rotation and scaling of the virtual object can be enabled or disabled as the aggregated output.
