Abstract

User input interpretation mechanisms can pass along user input without delay by initially treating it as freeform movement and passing it along unmodified, rather than waiting to receive a sufficient quantity of user input from which to derive a user'"'"'s intentions. User input within a defined range from an initial point is freeform movement, passed along unmodified, while user input beyond that range can be confined to a groove if it evidences an intention to move in a precisely linear manner. Grooves can be established to aid in precise vertical movement, with no horizontal deviations, precise horizontal movement, with no vertical deviations, or any other orientation. Before being passed along, user input in groove regions can be modified to center the input within the groove region and eliminate human inaccuracies, such as slight deviations to either side. User input can escape groove regions by moving orthogonally to them.

Claims

1. One or more computer-readable memory comprising computer-executable instructions for interpreting user input, the computer-executable instructions directed to steps comprising:

receiving moving user input, the moving user input having commenced from an origin point;

passing along the moving user input, as it is received, in an unmodified form while the user input remains within a freeform movement threshold distance away from the origin point; and

passing along a modified user input in response to the moving user input having moved beyond the freeform movement threshold distance away from the origin point and into a groove region, wherein the modified user input is modified to center the moving user input along the groove region.

2. The computer-readable memory of claim 1, comprising further computer-executable instructions for again passing along the moving user input in the unmodified form, after the passing along of the modified user input, in response to the moving user input having subsequently moved orthogonally to the groove region beyond a groove escape threshold boundary.

3. The computer-readable memory of claim 2, comprising further computer-executable instructions for passing along again-modified user input in response to the moving user input having subsequently moved beyond a second freeform movement threshold distance away from a point at which the moving user input moved beyond the groove escape threshold boundary and into a second groove region, wherein the again modified user input is modified to center the moving user input along the second groove region.

4. The computer-readable memory of claim 1, wherein the groove region is a pre-defined linear region located in alignment with the origin point.

5. The computer-readable memory of claim 1, comprising further computer-executable instructions for:

determining that the moving user input is substantially directed along a direction; and

establishing the groove region as a linear region aligned in the direction and located at a location of the moving user input when the computer-executable instructions determined that the moving user input was substantially directed along the direction.

6. The computer-readable memory of claim 1, comprising further computer-executable instructions for passing along an activation event at the origin point in response to the moving user input not exceeding an activation threshold prior to being ended by the user.

7. The computer-readable memory of claim 6, comprising further computer-executable instructions for generating, in response to the moving user input not exceeding an activation threshold prior to being ended by the user, user input to undo the moving user input that was passed along.

8. The computer-readable memory of claim 1, wherein the computer-executable instructions for passing along the modified user input are executed only in response to:

the moving user input having moved beyond the freeform movement threshold distance away from the origin point, and the moving user input having subsequently moved into the groove region;

wherein immediately preceding positions of the moving user input are substantially along a direction of the groove region.

9. A method of interpreting, on a computing device, user input to the computing device, the method comprising the steps of:

receiving, at the computing device, moving user input provided by a user through user interface input hardware that is communicationally coupled to the computing device, the moving user input having commenced from an origin point;

passing along, to processes executing on the computing device, the moving user input, as it is received, in an unmodified form while the user input remains within a freeform movement threshold distance away from the origin point; and

, to the processes executing on the computing device, a modified user input in response to the moving user input having moved beyond the freeform movement threshold distance away from the origin point and into a groove region, wherein the modified user input is modified to center the moving user input along the groove region.

10. The method of claim 9, further comprising the steps of:

again passing along, to the processes executing on the computing device, the moving user input in the unmodified form, after the passing along of the modified user input, in response to the moving user input having subsequently moved orthogonally to the groove region beyond a groove escape threshold boundary.

11. The method of claim 10, further comprising the steps of:

passing along, to the processes executing on the computing device, again-modified user input in response to the moving user input having subsequently moved beyond a second freeform movement threshold distance away from a point at which the moving user input moved beyond the groove escape threshold boundary and into a second groove region, wherein the again modified user input is modified to center the moving user input along the second groove region.

12. The method of claim 9, wherein the groove region is a pre-defined linear region located in alignment with the origin point.

13. The method of claim 9, further comprising the steps of:

determining that the moving user input is substantially directed along a direction; and

establishing the groove region as a linear region aligned in the direction and located at a location of the moving user input when the computer-executable instructions determined that the moving user input was substantially directed along the direction.

14. The method of claim 9, further comprising the steps of passing along, to the processes executing on the computing device, an activation event at the origin point in response to the moving user input not exceeding an activation threshold prior to being ended by the user.

15. The method of claim 14, further comprising the steps of generating, on the computing device, in response to the moving user input not exceeding an activation threshold prior to being ended by the user, user input to undo the moving user input that was passed along.

16. The method of claim 9, further comprising the steps of passing along, to the processes executing on the computing device, the modified user input only in response to:

the moving user input having moved beyond the freeform movement threshold distance away from the origin point, and the moving user input having subsequently moved into the groove region;

wherein immediately preceding positions of the moving user input are substantially along a direction of the groove region.

17. A computing device comprising a user input peripheral;

one or more processing units; and

one or more computer-readable media comprising computer-executable instructions that, when executed by the one or more processing units, perform steps comprising;

receiving moving user input from the user input peripheral, the moving user input having commenced from an origin point;

passing along the moving user input, as it is received from the user input peripheral, in an unmodified form while the user input remains within a freeform movement threshold distance away from the origin point; and

passing along a modified user input in response to the moving user input having moved beyond the freeform movement threshold distance away from the origin point and into a groove region, wherein the modified user input is modified to center the moving user input along the groove region.

18. The computing device of claim 17, wherein the user input peripheral is a touchscreen, and wherein further the moving user input is received when a user presses and drags at least one finger on the touchscreen.

19. The computing device of claim 18, wherein the touchscreen is utilized to both enable the user to input the moving user input and, simultaneously, to display, to the user, one or more graphical user interface elements whose display is controlled, at least in part, by the moving user input passed along by the execution of the computer-executable instructions.

20. The computing device of claim 17, wherein the user input peripheral is a video camera, and wherein further the moving user input is received when a user performs pre-defined motions that are captured by the video camera.
