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:

adding a first dot of ink;

receiving a tap input after the first dot of ink has been added;

responsive to receiving the tap input, determining whether the first dot of ink was recently added;

responsive to determining that the first dot of ink was recently added, adding a second dot of ink; and

responsive to determining that the first dot of ink was not recently added, determining whether the location of the tap input is at a selectable object.

2. The computer-readable medium of claim 1, wherein ink is recently added only if it was added less than one second ago.

3. The computer-readable medium of claim 2, wherein ink is recently added only if it was added less than half a second ago.

4. The computer-readable medium of claim 1, wherein the steps further include:

responsive to determining that the tap input is at a selectable object, determining whether the selectable object has already been selected; and

responsive to determining that the selectable object has not already been selected, selecting the selectable object.

5. The computer-readable medium of claim 1, wherein the steps further include:

responsive to determining that the tap input is not at a selectable object, determining whether the tap input is at an inline space; and

responsive to determining that the tap input is at an inline space, placing an insertion point.

6. The computer-readable medium of claim 1, wherein the steps further include:

responsive to determining that the tap input is not at a selectable object, determining whether the tap input is at an inline space;

responsive to determining that the tap input is not at an inline space, determining whether the location of the tap input is near existing ink; and

responsive to determining that the location of the tap input is near existing ink, adding a dot of ink at the location of the tap input.

7. The computer-readable medium of claim 1, wherein the steps further include:

responsive to determining that the location of the tap input is not at a selectable object, determining whether the location of the tap input is at an inline space;

responsive to determining that the location of the tap input is not at an inline space, determining whether the location of the tap input is near existing ink;

responsive to determining that the location of the tap input is not near existing ink, determining whether the location of the tap input is at an active object; and

responsive to determining that the location of the tap input is not at an active object, placing an insertion point.

8. The computer-readable medium of claim 1, wherein the steps further include:

if the tap input is at a selectable object, then determining whether the selectable object has already been selected;

if the tap input is not a selectable object, then determining whether the tap is at an inline space.

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

adding first ink;

receiving a tap input after the first ink has been added;

responsive to receiving the tap input, determining whether the first ink was recently added; and

responsive to an outcome of the step of determining, choosing between either adding second ink or determining whether the location of the tap input is at a selectable object, depending upon whether the first ink was recently added.

10. The computer-readable medium of claim 9, wherein the computer-executable instructions are further for choosing, if it is determined that the ink was not recently added, between either determining whether the selectable object has already been selected or determining whether the tap input is at an inline space, depending upon whether the location of the tap input is at the selectable object.

11. The computer-readable medium of claim 9, wherein the computer-executable instructions are further for:

if it is determined that the tap input is not an inline space, then determining whether the location of the tap input is near existing ink; and

if it is determined that the tap input is at an inline space, then placing an insertion point.

12. The computer-readable medium of claim 11, wherein the computer-executable instruction are further for:

if it is determined that the location of the tap input is near existing ink, then adding a dot of ink at the location of the tap input if it is determined that the location of the tap input is near existing ink; and

if it is determined that the location of the tap input is not near existing ink, then determined whether the location of the tap input is at an active object.

13. The computer-readable medium of claim 12, wherein the computer-executable instructions are further for placing an insertion point if it is determined that the location of the tap input is not at an active object.

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

responsive to a tap input, determining whether first ink existing prior to the tap input was added within a predetermined period of time prior to the tap input; and

responsive to an outcome of the step of determining, choosing between either adding second ink at a location of the tap input or selecting an object at the location of the tap input, depending upon whether the first ink was added within the predetermined period of time.
