Analog input mapping for hand-held computing devices
A first hand-held computing device includes an analog input device and a processor. The analog input device generates analog input. The processor receives the analog input and converts the analog input to coordinates. The processor then maps the coordinates to a button for a second hand-held computing device and generates an event indicating a state of the button for the second hand-held computing device.
1. A method of converting analog input in a first hand-held computing device, the method comprising:
receiving the analog input from an analog input device in the first hand-held computing device;
converting the analog input to polar coordinates;
mapping the polar coordinates to a button for a second hand-held computing device; and
generating an event indicating a state of the button for the second hand-held computing device, wherein software executed on the second hand-held computing device may be compatibly executed on the first hand-held computing device.
2. The method of claim 1 wherein the polar coordinates may further be expressed as x, y components.
3. The method of claim 1 further comprising retrieving a table of polar coordinates corresponding to the button for the second hand-held computing device, and wherein mapping the polar coordinates to the button is based on the table.
4. The method of claim 1 wherein the second hand-held computing device comprises a legacy PALM operating system button implementation.
5. The method of claim 1 wherein the second hand-held computing device comprises a 5-way button implementation.
6. The method of claim 1 wherein the second hand-held computing device comprises an 8-way button implementation.
7. The method of claim 1 wherein the second hand-held computing device comprises a 4-way button implementation.
8. A computer-readable storage medium having embodied thereon mapping software program, the mapping software being executable by a processor to perform a method for converting analog input in a first hand-held computing device, the method comprising:
receiving the analog input from an analog input device in the first hand-held computing device;
converting the analog input to polar coordinates;
mapping the polar coordinates to a button for a second hand-held computing device; and
generating an event indicating a state of the button for the second hand-held computing device, wherein software executed on the second hand-held computing device may be compatibly executed on the first hand-held computing device.
9. The computer-readable storage medium of claim 8 , wherein the polar coordinates may further be expressed as x, y components.
10. The computer-readable storage medium of claim 8 , the method further comprising retrieving a table of polar coordinates corresponding to the button for the second hand-held computing device, and wherein mapping the polar coordinates to the button is based on the table.
11. The computer-readable storage medium of claim 8 , wherein the second hand-held computing device comprises a legacy PALM operating system button implementation.
12. The computer-readable storage medium of claim 8 , wherein the second hand-held computing device comprises a 5-way button implementation.
13. The computer-readable storage medium of claim 8 , wherein the second hand-held computing device comprises an 8-way button implementation.
14. The computer-readable storage medium of claim 8 , wherein the second hand-held computing device comprises a 4-way button implementation.
15. A first hand-held computing device comprising:
an analog input device configured to generate analog input; and
a processor configured to receive the analog input from the analog input device, the processor further configured to execute software stored in memory, the software for:
converting the analog input to polar coordinates;
mapping the polar coordinates to a button for a second hand-held computing device; and
generating an event indicating a state of the button for the second hand-held computing device, wherein software executed on the second hand-held computing device may be compatibly executed on the first hand-held computing device.
16. The first hand-held computing device of claim 15 wherein the polar coordinates may further be expressed as x, y components.
17. The first hand-held computing device of claim 15 wherein the processor is further configured to retrieve a table of polar coordinates corresponding to the button for the second hand-held computing device, and wherein mapping the polar coordinates to the button is based on the table.
18. The first hand-held computing device of claim 15 wherein the second hand-held computing device comprises a legacy PALM operating system button implementation.
19. The first hand-held computing device of claim 15 wherein the second hand-held computing device comprises a 5-way button implementation.
