Abstract

Disclosed herein are representative embodiments of tools and techniques for providing one or more ink-trace predictions for shape writing. According to one exemplary technique, a portion of a shape-writing shape is received by a touchscreen. Based on the portion of the shape-writing shape, an ink trace is displayed. Also, predicted text is determined. The ink trace corresponding to a first portion of the predicted text. Additionally, an ink-trace prediction is provided connecting the ink trace to at least one or more keyboard keys corresponding to one or more characters of a second portion of the predicted text.

Claims

1. One or more computer-readable storage media storing computer-executable instructions for causing a computing system to perform a method, the method comprising:

receiving a portion of a shape-writing shape;

based on the portion of the shape-writing shape, displaying an ink trace;

determining at least one predicted text, the ink trace corresponding to a first portion of the at least one predicted text; and

providing an ink-trace prediction connecting the ink trace to at least one or more keyboard keys corresponding to one or more characters of a second portion of the at least one predicted text.

2. The one or more computer-readable storage media of claim 1, wherein the ink-trace prediction comprises a line that extends from the ink trace.

3. The one or more computer-readable storage media of claim 1, further comprising determining the ink-trace prediction based on the one or more characters of the second portion of the at least one predicted text.

4. The one or more computer-readable storage media of claim 1, wherein the one or more keyboard keys are connected by the ink-trace prediction ordered based at least in part on an order of one or more characters of the second portion of the at least one predicted text.

5. The one or more computer-readable storage media of claim 1, wherein the determining the at least one predicted text is based at least in part on the received portion of the shape-writing shape and a prediction context.

6. The one or more computer-readable storage media of claim 1, further comprising:

determining that a confidence measure for the at least one predicted text satisfies a confidence threshold; and

wherein the displaying the ink-trace prediction is responsive to the determining that the confidence measure for the at least one predicted text satisfies the confidence threshold.

7. The one or more computer-readable storage media of claim 1, wherein the ink-trace prediction is displayed with one or more different visual characteristics than the ink trace.

8. The one or more computer-readable storage media of claim 1, wherein the at least one predicted text comprises first predicted text, wherein the portion of the shape-writing shape is a first portion of the shape-writing shape, and wherein the method further comprises:

receiving an additional portion of the shape-writing shape; and

based at least in part on the additional portion of the shape-writing shape, extending the ink-trace prediction.

9. The one or more computer-readable storage media of claim 1, wherein the at least one predicted text comprises first predicted text, wherein the portion of the shape-writing shape is a first portion of the shape-writing shape, and wherein the method further comprises:

receiving an additional portion of the shape-writing shape;

based on the first portion of the shape-writing shape and the additional portion of the shape-writing shape, determining second predicted text; and

displaying an updated ink-trace prediction based on the second predicted text.

10. The one or more computer-readable storage media of claim 1, further comprising:

receiving the at least one predicted text in a text edit field;

receiving one or more presses of a modifier key on an on-screen keyboard; and

based at least in part on the receiving the one or more presses of the modifier key on the on-screen keyboard, changing a case of the at least one predicted text in the text edit field.

11. A method comprising:

receiving, by a touchscreen, a portion of a shape-writing shape;

based on the portion of the shape-writing shape, displaying an ink trace;

determining at least one predicted text, the ink trace corresponding to a first portion of the at least one predicted text; and

providing an ink-trace prediction connecting the ink trace to one or more keyboard keys corresponding to a second portion of the at least one predicted text.

12. The method of claim 11, wherein the ink-trace prediction comprises a line that extends from the ink trace.

13. The method of claim 11, further comprising determining the ink-trace prediction based at least in part on the one or more characters of the second portion of the at least one predicted text.

14. The method of claim 11, wherein the determining the at least one predicted text is based at least on the portion of the shape-writing shape and a prediction context.

15. The method of claim 11, further comprising:

determining a confidence measure for the at least one predicted text;

determining that the confidence measure for the at least one predicted text satisfies a confidence threshold; and

wherein the displaying the ink-trace prediction is responsive to the determining that the confidence measure for the at least one predicted text satisfies the confidence threshold.

16. The method of claim 11, wherein the one or more keyboard keys are connected by the ink-trace prediction ordered based at least in part on an order of the one or more characters of the second portion of the at least one predicted text.

17. The method of claim 11, wherein the at least one predicted text comprises first predicted text, wherein the portion of the shape-writing shape is a first portion of the shape-writing shape, and wherein the method further comprises:

receiving an additional portion of the shape-writing shape;

based on the first portion of the shape-writing shape and the additional portion of the shape-writing shape, determining second predicted text; and

displaying an updated ink-trace prediction based on the second predicted text.

18. The method of claim 11, wherein the at least one predicted text comprises first predicted text, wherein the portion of the shape-writing shape is a first portion of the shape-writing shape, and wherein the method further comprises:

receiving an additional portion of the shape-writing shape; and

based at least in part on the additional portion of the shape-writing shape, extending the ink-trace prediction.

19. The method of claim 11, further comprising:

receiving the at least one predicted text in a text edit field;

receiving one or more presses of a modifier key on an on-screen keyboard; and

based at least in part on the receiving the one or more presses of the modifier key on the on-screen keyboard, changing a case of the at least one predicted text in the text edit field.

20. A computing device comprising at least one processor and memory, the memory storing computer-executable instructions for causing the computing device to perform a method, the method comprising:

receiving, by a touchscreen of the computing device, a portion of a shape-writing shape;

based on the portion of the shape-writing shape, displaying an ink trace;

based on the portion of the shape-writing shape, determining at least one predicted text, the ink trace corresponding to a first portion of the at least one predicted text;

providing an ink-trace prediction, the ink-trace prediction comprising a line which extends from the ink trace and at least connects to one or more keyboard keys in an order corresponding to an order of one or more characters of a second portion of the at least one predicted text;

determining that the shape-writing shape is completed; and

entering the at least one predicted text into a text edit field.
