Abstract

The present invention relates to a system, method and medium for receiving and acting upon user input. In one embodiment, the user may only have access to a limited input device, like a stylus. Using the present invention, a user is provided with intuitive responses from the system based on inputs from the limited input device.

Claims

1. One or more computer-readable media storing computer-executable instructions that when executed perform operations comprising:

receiving user input at a digitizer;

determining whether the user input moves beyond a first threshold;

determining whether the user input ends before an amount of time; and

responsive to the user input failing to exceed the first threshold and ending before the amount of time, classifying the user input as a tap.

2. The one or more computer-readable media of claim 1 wherein the user input is caused by the digitizer detecting a user'"'"'s finger in contact with the digitizer, and the user input ends when the digitizer no longer detects the user'"'"'s finger in contact with the digitizer.

3. The one or more computer-readable media of claim 1 wherein the first threshold includes at least one of:

a distance of movement, a rate of movement, an acceleration of movement, or any combination thereof.

4. The one or more computer-readable media of claim 1 wherein the first threshold is not changed based on an object associated with the user input.

5. The one or more computer-readable media of claim 1 wherein the first threshold depends on an object associated with the user input.

6. The one or more computer-readable media of claim 1 wherein the computer-executable instructions perform operations further comprising:

selecting an object within proximity of the tap when the object has not already been selected.

7. The one or more computer-readable media of claim 1 wherein the computer-executable instructions perform operations further comprising:

de-selecting an object within proximity of the tap when the object has already been selected.

8. The one or more computer-readable media of claim 1 wherein the computer-executable instructions perform operations further comprising:

placing an insertion point at a location within proximity of the tap when the location of the tap was within text.

9. One or more computer-readable media storing computer-executable instructions that when executed perform operations comprising:

receiving user input at a digitizer;

determining whether the user input moves beyond a first threshold; and

responsive to the user input moving beyond the first threshold, classifying the user input as a stroke.

11. The one or more computer-readable media of claim 9 wherein the first threshold includes at least one of:

a distance of movement, a rate of movement, an acceleration of movement, or any combination thereof.

12. The one or more computer-readable media of claim 9 wherein the computer-executable instructions perform operations further comprising:

when the stroke started within proximity to a draggable object and a drag threshold had been exceeded, performing a function with the draggable object based on the stroke; and

when the drag threshold has not been exceeded, maintaining the draggable object at a current state.

13. The one or more computer-readable media of claim 9 wherein the computer-executable instructions perform operations further comprising:

when the stroke did not start within proximity to a draggable object, determining whether an area under the stroke is inkable; and

when the area under the stroke inkable, performing inking based on the stroke.

10. The one or more computer-readable media of 9 wherein the user input is caused by the digitizer detecting a user'"'"'s finger in contact with the digitizer.

14. A computing device, comprising:

one or more processors; and

one or more computer-readable media storing computer-executable instructions that when executed by the one or more processors perform operations comprising;

receiving user input at a digitizer;

determining whether the user input moves beyond a first threshold;

responsive to the user input moving beyond the first threshold, classifying the user input as a stroke;

determining whether the user input ends before an amount of time; and

responsive to the user input failing to exceed the first threshold within the amount of time and ending before the amount of time, classifying the user input as a tap.

15. The computing device of claim 14 wherein the user input is caused by the digitizer detecting a user'"'"'s finger in contact with the digitizer, and the user input ends when the digitizer no longer detects the user'"'"'s finger in contact with the digitizer.

16. The computing device of claim 14 wherein the computer-executable instructions perform operations further comprising:

selecting a first object within proximity of the tap when the first object has not already been selected; and

de-selecting a second object within proximity of the tap when the second object has already been selected.

17. The computing device of claim 14 wherein the computer-executable instructions perform operations further comprising:

placing an insertion point at a location within proximity of the tap when the location of the tap was within text.

18. The computing device of claim 14 wherein the computer-executable instructions perform operations further comprising:

when the stroke started within proximity to a draggable object and a drag threshold had been exceeded, performing a function with the draggable object based on the stroke; and

when the drag threshold has not been exceeded, maintaining the draggable object at a current state.

19. The computing device of claim 14 wherein the computer-executable instructions perform operations further comprising:

when the stroke did not start within proximity to a draggable object, determining whether an area under the stroke is inkable; and

when the area under the stroke inkable, performing inking based on the stroke.

20. The computing device of claim 14 wherein the first threshold includes at least one of:

a distance of movement, a rate of movement, an acceleration of movement, or any combination thereof.
