Abstract

A user interface for an electronic device and method for locating an interactive element having a position along an interactive surface of a touch sensitive interface of an electronic device are provided. The user interface has a touch sensitive interface, which includes one or more interactive elements having a position along an interactive surface, and a surface sensor, the surface sensor being adapted for receiving from a user a pattern of interaction with the touch sensitive interface at a location along the interactive surface. The user interface further includes an alert device and a controller. The controller includes a user interaction detection module, which is adapted for detecting the location of the pattern of interaction and comparing the location to the position of the one or more interactive elements. The controller further includes a feedback module, which is adapted for actuating the alert device for producing a user perceivable alert signal having a level of alert which is a function of the distance between the location of the pattern of interaction and the position of a closest one of the one or more interactive elements, wherein as the distance between the location of the pattern of interaction and the position of the closest one of the one or more interactive elements changes, the level of the alert changes.

Claims

1. A user interface for an electronic device comprising:

a touch sensitive interface including one or more interactive elements having a position along an interactive surface, wherein the one or more interactive elements includes a speaker, and a surface sensor, the surface sensor being adapted for receiving from a user a pattern of interaction with the touch sensitive interface at a location along the interactive surface, wherein the pattern of interaction includes a shape of at least a portion of an ear of the user placed adjacent to the touch sensitive interface;

an alert device; and

a controller including

a user interaction detection module adapted for detecting the location of the pattern of interaction and comparing the location to the position of the one or more interactive elements; and

a feedback module adapted for actuating the alert device for producing a user perceivable alert signal having a level of alert which is a function of the distance between the location of the pattern of interaction and a previously determined desired reference position relative to the one or more interactive elements, wherein as the distance between the location of the pattern of interaction and the previously determined desired reference position changes, the level of the alert changes.

2. A user interface for an electronic device in accordance with claim 1, wherein the touch sensitive interface is a touch sensitive display.

3. A user interface for an electronic device in accordance with claim 2, wherein the one or more interactive elements include an image of a virtual key visually represented along the interactive surface via the touch sensitive display.

4. A user interface for an electronic device in accordance with claim 3, wherein the pattern of interaction includes at least one of a portion of a finger of the user or a tip of a stylus.

5. A user interface for an electronic device in accordance with claim 1, wherein the controller additionally includes a learning module, which is adapted for detecting the pattern of interaction with the touch sensitive interface received from the user, when the user indicates that the location of the pattern of interaction coincides with the position of a corresponding one of the one or more interactive elements.

6. A user interface for an electronic device in accordance with claim 1, wherein the alert device produces an audible alert.

7. A user interface for an electronic device in accordance with claim 1, wherein the alert device produces a vibrational alert.

8. A user interface for an electronic device in accordance with claim 1, wherein the level of the alert increases as the distance between the location of the pattern of interaction and the position of the closest one of the one or more interactive elements increases.

9. A user interface for an electronic device in accordance with claim 1, wherein the level of the alert decreases as the distance between the location of the pattern of interaction and the position of the closest one of the one or more interactive elements increases.

10. A user interface for an electronic device in accordance with claim 1, wherein a second user perceivable alert signal, is actuated when the location of the pattern of interaction coincides with the position of the closest one of the one or more interactive elements.

11. A user interface for an electronic device in accordance with claim 10, wherein the second user perceivable alert signal is produced by the alert device.

12. A user interface for an electronic device in accordance with claim 10, wherein the second user perceivable alert signal is produced by a second alert device.

13. A user interface for an electronic device in accordance with claim 10, wherein the second user perceivable alert signal is an audible alert.

14. A user interface for an electronic device in accordance with claim 1, further comprising a user actuatable element, which when activated is adapted to select a particular one of the one or more interactive elements with which the detected location of the pattern of interaction coincides.

15. A method in accordance with claim 1, whereby the perceivable alert signal from the feedback module is adapted to assist the user to navigate the at least portion of the user'"'"'s ear toward the previously determined desired reference position relative to the speaker.

16. A user interface for an electronic device comprising:

a touch sensitive interface including one or more interactive elements having a position along an interactive surface, wherein the one or more interactive elements includes a microphone, and a surface sensor, the surface sensor being adapted for receiving from a user a pattern of interaction with the touch sensitive interface at a location along the interactive surface, wherein the pattern of interaction includes a shape of at least a portion of a face of the user placed adjacent to the touch sensitive interface;

an alert device; and

a controller including

a user interaction detection module adapted for detecting the location of the pattern of interaction and comparing the location to the position of the one or more interactive elements; and

a feedback module adapted for actuating the alert device for producing a user perceivable alert signal having a level of alert which is a function of the distance between the location of the pattern of interaction and a previously determined desired reference position relative to the one or more interactive elements, wherein as the distance between the location of the pattern of interaction and the previously determined desired reference position changes, the level of the alert changes.

17. A method in accordance with claim 16, whereby the perceivable alert signal from the feedback module is adapted to assist the user to navigate the at least portion of the user'"'"'s face toward the previously determined desired reference position relative to the microphone.

18. A method of locating an interactive element positioned on an interactive surface of a touch sensitive interface, the method comprising:

detecting a location of a nonpoint user interaction with the touch sensitive interface relative to the position of the interactive element;

providing a user perceivable signal having a characteristic that is a function of a distance between the location of the nonpoint user interaction with the touch sensitive interface and the position of the interactive element;

detecting a change in the location of the nonpoint user interaction with the touch sensitive interface relative to the position of the interactive element; and

changing the characteristic of the user perceivable signal based upon the change in distance between the location of the nonpoint user interaction with the touch sensitive interface and the position of the interactive element.

19. A method in accordance with claim 18 further comprising discontinuing the production of the user perceivable signal and producing a second user perceivable signal when the location of the nonpoint user interaction with the touch sensitive interface coincides with the position of the interactive element.
