Abstract

Handwritten shorthand is used and interpreted in a stylus-based interface to trigger expanded text, implement functions, and/or launch executable programs. A user may be able to select a type of shorthand entry to define, such as a text-expansion-type shorthand entry, a function-type shorthand entry, or a program-type shorthand entry. Upon receiving handwritten input, a computer may determine whether or not to interpret the handwritten input as shorthand, or whether to act upon the handwritten shorthand, depending upon the context in which it is written.

Claims

1. In a computer, a method comprising the steps of:

assigning a same symbol to each of a text expansion, a program, and a function, wherein the same symbol is assigned as a shorthand entry of each of the text expansion, the program, and the function;

receiving handwritten user input;

determining that the handwritten user input represents the symbol;

determining that the handwritten user input is a sole input, wherein the sole input does not have associated with it another user input; and

based on the handwritten user input comprising the sole input, carrying out the function by generating an output.

3. The method of claim 1, wherein the context is associated an entity receiving the handwritten user input and a number of symbols in the handwritten user input.

2. A computer-readable medium storing computer executable instructions that when executed by a computer, cause the computer to perform a method comprising:

assigning a same symbol to each of a text expansion, a program, and a function, wherein the same symbol is assigned as a shorthand entry of each of the text expansion, the program, and the function;

receiving handwritten user input;

determining that the handwritten user input represents the symbol;

determining that the handwritten user input is a sole input, wherein the sole input does not have associated with it another user input; and

based on the handwritten user input comprising the sole input, carrying out the function by generating an output.

4. In a computer, a method comprising steps of:

receiving a handwritten user input including a first symbol, which is a shorthand entry of both of an expanded text and a program;

determining that the handwritten user input includes a second symbol in addition to the first symbol;

based on the handwritten user input including the second symbol, selecting the text expansion to be displayed; and

displaying the text expansion in place of the first symbol.

5. The method of claim 4, wherein the first symbol consists of a single word.

6. The method of claim 4, wherein the second symbol includes any handwritten user input other than the first symbol that is simultaneously displayed with the first symbol.

7. The method of claim 4, wherein the second symbol consists of any handwritten user input on a same line as the first symbol and simultaneously displayed with the first symbol.

8. The method of claim 4, wherein the step of selecting includes determining that a total handwritten user input word count is greater than one.

9. The method of claim 8, the handwritten user input does not include the second handwritten input and therefore launching the program associated with the first handwritten user input.

10. The method of claim 8, wherein the total handwritten user input count is greater than one and based on a determination that the handwritten user input includes the second handwritten user input either replacing the first handwritten user input with the expanded text or displaying the first and second handwritten user inputs.

11. The method of claim 4, further including third determining whether all handwritten user input has stopped, the step of selecting being performed in response to determining that all handwritten user input has stopped.

12. The method of claim 4, further including a step of waiting a predetermined period of non-zero time after the step of receiving, the step of selecting being performed after the step of waiting.

14. The method of claim 4, further including:

prior to receiving the first handwritten user input, receiving user input identifying the text expansion and the program.

13. A computer-readable medium storing computer-executable instructions that, when executed by a computing device, cause the computing device to perform a method comprising:

receiving a handwritten user input including a first symbol, which is a shorthand entry of both of an expanded text and a program;

determining that the handwritten user input includes a second symbol in addition to the first symbol;

based on the handwritten user input including the second symbol, selecting the text expansion to be displayed; and

displaying the text expansion in place of the first symbol.

15. In a computer, a method comprising steps of:

receiving handwritten user input;

recognizing the handwritten user input to determine a symbol;

determining expanded text represented by the symbol;

determining a function represented by the symbol wherein the function takes an input and generates an output;

determining a program represented by the symbol;

automatically determining that the handwritten user input is a sole entry; and

launching the program.

17. The method of claim 15, further including, prior to receiving the handwritten user input, receiving user input identifying the symbol, the text expansion, and the program.

16. A computer-readable medium storing computer-executable instructions that, when executed by a computing device, cause the computing device to perform a method comprising:

receiving hand written user input;

recognizing the handwritten user input to determine a symbol;

determing expanded text represented by the symbol;

determing a function represented by the symbol wherein the function takes an input and generates an output;

determining a program represented by the symbol; and

launching the program.
