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. A computer-readable medium storing computer-executable instructions for performing steps comprising:

receiving a user input to a digitizer;

classifying the user input as a stroke if the user input satisfies a first move threshold;

classifying the user input as a tap if the user input fails to satisfy both the first move threshold and a time threshold;

classifying the user input as a hold if the user input satisfies the time threshold but fails to satisfy both the first move threshold and a second move threshold different from the first move threshold, wherein after determining the hold, triggering a definable event; and

classifying the user input as a hold and drag if the user input satisfies both the time threshold and the second move threshold but fails to satisfy the first move threshold.

2. The computer-readable medium of claim 1 wherein receiving the user input to the digitizer includes detecting a user'"'"'s finger by the digitizer.

3. A computer-readable medium storing computer-executable instructions for performing steps comprising:

receiving user input to a digitizer;

first determining whether the user input moves at least a first distance;

second determining whether the user input ends before a certain amount of time; and

responsive to the user input failing to move at least the first distance within the certain amount of time and failing to end before the certain amount of time, third determining whether the user input moves at least a second distance larger than the first distance,

wherein if the user input satisfies the first determining step and second determining step but fails to satisfy the third determining step, classifying the user input as a tap and triggering a definable event.

4. The computer-readable medium of claim 3, wherein the user input is caused by a stylus contacting the digitizer, and the user input ends when the stylus no longer contacts the digitizer.

5. The computer-readable medium of claim 3, wherein the computer-executable steps are further for performing steps of:

responsive to the user input moving at least the first distance as determined by the step of first determining, classifying the user input as a first type of input;

responsive to the user input ending before the certain amount of time as determined by the step of second determining, classifying the user input as a second type of input different from the first type of input; and

responsive to an outcome of the step of third determining, classifying the user input as either a third type of input different from the first and second types of input or a fourth type of input different from the first, second, and third types of input.

6. The computer-readable medium of claim 3, wherein the computer-executable instructions are further for performing a step of, responsive to the user input moving at least the first distance as determined by the step of first determining, fourth determining whether the input begins on a draggable object.

7. The computer-readable medium of claim 6, wherein the computer-executable instructions are further for performing a step of, responsive to the user input beginning on a draggable object as determined by the step of fourth determining, fifth determining whether the user input satisfies a drag threshold.

8. The computer-readable medium of claim 3 wherein the user input is caused by a 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.

9. A computer-readable medium storing computer-executable instructions for performing steps comprising:

receiving a user'"'"'s input; and

first determining whether the input is a stroke based on a first move threshold;

if the input is not a stroke, then second determining whether the input is a tap based on a time threshold and triggering a definable event;

if the input is neither a stroke nor a tap, then third determining whether the stroke is a hold based on a second move threshold larger than the first move threshold, wherein said input satisfies said time threshold and said input does not satisfy said second move threshold;

or

a hold and drag when the input satisfies said time threshold and said input satisfies said second move threshold.

11. The computer-readable medium of claim 9, wherein, if said input does not satisfy said first move threshold and said input does not satisfy said time threshold, the input is classified as a tap.

12. The computer-readable medium of claim 9, wherein the computer-executable instructions are further for performing a step of simulating a right mouse click responsive to said input being classified as a hold.

13. The computer-readable medium of claim 9, wherein the computer-executable instructions are further for performing a step of dragging a selected object responsive to said input being classified as a hold and drag.

14. The computer-readable medium of claim 9 wherein the user'"'"'s input is received at a touch-sensitive display that detects contact with a user'"'"'s finger.

10. The computer-readable medium of 9, wherein, if said input satisfies said first move threshold, the input is classified as a stroke.
