Abstract

Systems, methods, and computer-readable media for multipoint temporary anchoring are described. One embodiment includes a method having the steps of receiving a first input signal associated with a first area of an object within a graphical workspace, automatically determining that the first input signal is a locking signal, selecting the first area of the object based at least in part on the first input signal, and automatically locking the first area of the object.

Claims

1. A method, comprising:

receiving, by a processor, a first input signal associated with a first area of an object within a graphical workspace;

automatically determining, by the processor, that the first input signal is a locking signal;

selecting, by the processor, the first area of the object based at least in part on the first input signal; and

automatically locking the first area of the object by the processor before receipt of a second input signal associated with a second area of the object so that the first area of the object remains static while the second area of the object is subsequently manipulated in response to the second input signal.

2. The method of claim 1, wherein the first input signal is received from a touch sensitive input device.

3. The method of claim 2, wherein the touch sensitive input device comprises a touch screen configured to detect multiple areas of simultaneous contact.

4. The method of claim 1, wherein the first input signal comprises a plurality of discrete points of input.

5. The method of claim 4, further comprising determining a selection area based at least in part on the plurality of discrete points of input and wherein selecting the first area of the object is also based at least in part on the selection area.

6. The method of claim 1, further comprising unlocking the first area.

7. The method of claim 6, further comprising receiving an unlock signal;

and wherein unlocking the first area is based at least in part on the unlock signal.

8. The method of claim 1, further comprising automatically unlocking the first area after the second area is manipulated.

9. The method of claim 1, wherein automatically determining that the first signal is a locking signal is based at least in part on the duration of the first signal.

10. The method of claim 1, wherein automatically determining that the first signal is a locking signal is based at least in part on an input device associated with the first input signal.

11. The method of claim 1, further comprising:

receiving the second input signal associated with the second area of the object within the graphical workspace;

determining that the second input signal is a manipulation signal; and

manipulating the second area of the object based at least in part on the manipulation signal,

wherein the first area of the object remains static while the second area of the object is manipulated.

12. The method of claim 11, wherein

the first input signal is associated with a first point of contact with a touch sensitive input device;

and

the second input signal is associated with a second point of contact with a touch sensitive input device.

13. The method of claim 11, wherein

the first input signal is generated by detecting a substantially planar input on a touch sensitive input device;

and

the second input signal is generated by detecting a stylus input on the touch sensitive input device.

14. A method, comprising

receiving, by a computing device, a first input signal associated with a first area of an object within a graphical workspace;

determining, by the computing device, that the first input signal is a locking signal without user intervention and before receipt of a second input signal associated with a second area of the object;

selecting, by the computing device the first area of the object based at least in part on the first input signal; and

locking, by the computing device, the first area of the object so that while the second area of the object is subsequently manipulated in response to the second input signal, the first area of the object remains static.

15. A method, comprising:

receiving, at a computing device, a first input from a touch screen, the first input associated with a first area of an object within a graphical workspace;

locking, by the computing device, the first area of the object while the first input is being received to define a locked first area of the object;

after locking the first area of the object, receiving, by the computing device, a second input from the touch screen, the second input associated with a second area of the object within the graphical workspace which is not locked; and

editing, by the computing device, the object by changing the second area in response to the second input, the locked first area of the object remaining unchanged during editing.

16. A nontransitory computer-readable medium on which is encoded program code, the program code comprising:

program code for receiving a first input signal associated with a first area of an object within a graphical workspace;

program code for automatically determining that the first input signal is a locking signal prior to receipt of a second input signal associated with a second area of the object;

program code for selecting the first area of the object based at least in part on the first input signal; and

program code for automatically locking the first area of the object so that the first area of the object will remain static while the second area of the object is changed in response to the second input signal.

17. The computer-readable medium of claim 16, further comprising program code for determining that a plurality of discrete points of input are associated with a first area of an object within a graphical workspace.

18. The computer-readable medium of claim 16, further comprising program code for unlocking the first area.

19. The computer-readable medium of claim 16, further comprising program code for determining an end of a manipulation of a second area.

20. The computer-readable medium of claim 16, further comprising program code for receiving an unlock signal.

21. The computer-readable medium of claim 16, further comprising:

program code for receiving the second input signal associated with the second area of the object within the graphical workspace;

program code for determining that the second input signal is a manipulation signal; and

program code for manipulating the second area of the object based at least in part on the manipulation signal.

22. The computer-readable medium of claim 16, wherein program code for automatically locking the first area of the object comprises code for storing data so that, when a second area of the object is manipulated in response to further input, the first area of the object remains static while the second area of the object is changed.

23. A system, comprising:

a processor configured to;

receive a first input signal associated with a first area of an object within a graphical workspace;

automatically determine that the first input signal is a locking signal;

select the first area of the object based at least in part on the first input signal; and

automatically lock the first area of the object before receipt of a second input signal associated with a second area of the object.
