Abstract

A computer implemented method of implementing a touch screen user interface in conjunction with sensors for a computer system. A touchscreen area is provided for accepting text input strokes and for accepting icon manipulation strokes. A sensor is provided adjacent to the touchscreen area for registering sensor actuations from a user. In implementing the user interface, user input strokes are accepted into the touchscreen input area. User input strokes into touchscreen input area are interpreted as text input strokes when the sensor is actuated by the user during the user input strokes. User input strokes into the touchscreen input area are interpreted as icon manipulation strokes and not text input strokes when the sensor is not actuated by the user during the user input strokes. The nature of the sensor actuation is configured in order to require a deliberate touching, holding, grasping, or the like, to register an actuation of the sensor in order to distinguish between text input strokes and icon manipulation strokes, but not require so significant a user actuation as to interfere with a fluid and intuitive text entry process of the user. Interpreted input strokes can be rapidly displayed as characters on the touchscreen when the sensor is actuated by the user. An audible feedback can be generated to confirm the icon manipulation when the sensor is not actuated by the user. Similarly, a visual feedback can be generated to confirm the icon manipulation when the sensor is not actuated by the user.

Claims

1. A computer implemented method of implementing a touch screen user interface for a computer system, said method comprising the steps of:

providing touchscreen area for accepting text input strokes and for accepting icon manipulation strokes;

providing a sensor adapted to detect a grasp pressure adjacent to the touchscreen area for registering an actuation by a user;

accepting user input strokes into the touchscreen area;

interpreting user input strokes into the touchscreen area as text input strokes when the sensor is actuated by the user; and

interpreting user input strokes into the touchscreen area as icon manipulation strokes and not text input strokes when the sensor is not actuated by the user.

2. The method of claim 1 wherein said steps of interpreting user input strokes include immediately recognizing a character after said user completes at least one stroke that defines the character and when the sensor is actuated by the user.

3. The method of claim 1 wherein the step of interpreting user input strokes into the touchscreen area as icon manipulation strokes includes generating an audible feedback to confirm the icon manipulation when the sensor is not actuated by the user.

4. The method of claim 1 wherein the step of interpreting user input strokes into the touchscreen area as icon manipulation strokes includes generating a visual feedback on the touchscreen area to confirm the icon manipulation when the sensor is not actuated by the user.

5. The method of claim 1 further comprising the step of displaying an interpreted input stroke as a character onto a display when the sensor is actuated by the user.

6. The method of claim 1 wherein the touchscreen area is provided on a PID (personal information device).

7. The method of claim 1 wherein the touchscreen area is provided on a palmtop computer system.

8. A computer implemented method of implementing a user interface for a computer system, said method comprising the steps of:

providing a user input area for accepting text input strokes and for accepting icon manipulation strokes;

providing a sensor adapted to detect a grasp pressure adjacent to the user input area for registering an actuation by a user;

accepting user input strokes into the user input area;

interpreting user input strokes into the user input area as text input strokes when the sensor is actuated by the user; and

interpreting user input strokes into the user input area as icon manipulation strokes and not text input strokes when the sensor is not actuated by the user.

9. The method of claim 8 wherein the user input area is a touchscreen.

10. The method of claim 8 wherein the user input area is a digitizer pad.

11. The method of claim 8 wherein said steps of interpreting user input strokes include immediately recognizing a character after said user completes at least one stroke that defines the character and when the sensor is actuated by the user.

12. The method of claim 8 wherein the step of interpreting user input strokes into the user input area as icon manipulation strokes includes generating an audible feedback to confirm the icon manipulation when the sensor is not actuated by the user.

13. The method of claim 8 wherein the step of interpreting user input strokes into the user input area as icon manipulation strokes includes generating a visual feedback on the touchscreen to confirm the icon manipulation when the sensor is not actuated by the user.

14. The method of claim 8 further comprising the step of displaying an interpreted input stroke as a character onto a display when the sensor is actuated by the user.

15. The method of claim 8 wherein the user input area is provided on a PID (personal information device).

16. The method of claim 8 wherein the user input area is provided on a palmtop computer system.

17. A touchscreen equipped computer apparatus, comprising:

a touchscreen area for accepting text input strokes and for accepting icon manipulation strokes;

a sensor adapted to detect a grasp pressure adjacent to the user input area for registering an actuation by a user; and

a computer system coupled to the touchscreen area, the computer system configured to implement the steps of;

accepting user input strokes into the touchscreen area;

interpreting user input strokes into the touchscreen area as text input strokes when the sensor is actuated by the user; and

interpreting user input strokes into the touchscreen area as icon manipulation strokes and not text input strokes when the sensor is not actuated by the user.

18. The apparatus of claim 17 wherein said steps of interpreting user input strokes include immediately recognizing a character after said user completes at least one stroke that defines the character and when the sensor is actuated by the user.

19. The apparatus of claim 17 wherein the step of interpreting user input strokes into the touchscreen area as icon manipulation strokes includes generating an audible feedback using a speaker coupled to the computer system to confirm the icon manipulation when the sensor is not actuated by the user.

20. The apparatus of claim 17 wherein the step of interpreting user input strokes into the touchscreen area as icon manipulation strokes includes generating a visual feedback on the touchscreen area to confirm the icon manipulation when the sensor is not actuated by the user.
