Abstract

An electronic device includes a sensor for determining the position of an input member, such as a user'"'"'s finger or stylus, for example, relative to a user interface of the device. Before the input member contacts the user interface, the sensor detects the horizontal and vertical positions of the input member and generates positional signals indicative of those positions. A controller at the device determines the horizontal and vertical positions of the input member based on the positional signals, and generates first and second feedback signals as a function of the detected horizontal and vertical positions to indicate the input member position relative to the user interface.

Claims

1. A method for operating a user interface on an electronic device, the method comprising:

detecting a horizontal and vertical position of an input member relative to a User Interface (UI) prior to the input member contacting a user control on the UI;

indicating the horizontal position of the input member relative to the UI by generating a first feedback signal based on the detected horizontal position of the input member; and

indicating the vertical position of the input member relative to the UI by generating a second feedback signal based on the detected vertical position of the input member.

2. The method of claim 1 wherein at least one of the first and second feedback signals comprises audible feedback.

3. The method of claim 1 wherein at least one of the first and second feedback signals comprises tactile feedback.

4. The method of claim 3 further comprising generating the at least one first and second feedback signal as one or more bursts of tactile feedback based on the detected horizontal or vertical position of the input member.

5. The method of claim 1 wherein indicating the horizontal and vertical positions of the input member relative to the UI comprises varying properties of the first and second feedback signals as a function of the detected horizontal and vertical positions, respectively.

6. The method of claim 5 wherein varying properties of the first and second feedback signals comprises varying a frequency of one of the first and second feedback signals and the intensity of the other of the first and second feedback signals.

7. The method of claim 5 wherein varying properties of the first and second feedback signals comprises varying a frequency of at least one of the first and second feedback signals.

8. The method of claim 5 wherein varying properties of the first and second feedback signals comprises varying an intensity of at least one of the first and second feedback signals.

9. The method of claim 1 wherein the input member comprises one of the user'"'"'s finger and a stylus.

10. An electronic device comprising:

a User Interface (UI);

a sensor configured to generate positional signals upon detecting an input member proximate the UI prior to the input member contacting a user control on the UI; and

a programmable controller configured to;

calculate a horizontal and vertical position of the input member relative to the UI based on the positional signals;

indicate the horizontal position of the input member relative to the UI by generating a first feedback signal based on the detected horizontal position of the input member; and

indicate the vertical position of the input member relative to the UI by generating a second feedback signal based on the detected vertical position of the input member.

11. The device of claim 10 further comprising a loudspeaker, and wherein at least one of the first and second feedback signals comprises an audible sound rendered through the loudspeaker.

12. The device of claim 10 further comprising a tactile feedback generator, and wherein at least one of the first and second feedback signals comprises tactile feedback generated by the tactile feedback generator.

13. The device of claim 12 wherein the controller is further configured to control the tactile feedback generator to generate one or more bursts of tactile feedback based on the detected horizontal or vertical position of the input member.

14. The device of claim 10 wherein the programmable controller is configured to indicate the horizontal and vertical positions of the input member relative to the UI by varying properties of the first and second feedback signals as a function of the detected horizontal and vertical positions, respectively.

15. The device of claim 14 wherein the programmable controller is configured to vary the properties of the first and second feedback signals by varying a frequency of one of the first and second feedback signals, and varying the intensity of the other of the first and second feedback signals.

16. The device of claim 14 wherein the programmable controller is configured to vary the frequency of at least one of the first and second feedback signals.

17. The device of claim 14 wherein the programmable controller is configured to vary the intensity of at least one of the first and second feedback signals.
