Abstract

An electronic equipment, such as a mobile phone, includes a display for viewing content and/or information, a transducer operable to detect motion of the electronic equipment, and a control circuit for providing information to the display. The control circuit is responsive to detected motion to perform at least one of a pan or zoom of information provided to the display, wherein the pan and/or zoom correspond to a direction and velocity of the detected motion

Claims

1. An electronic equipment, comprising:

a display for viewing a virtual page;

a transducer operable to detect motion of the electronic equipment; and

a control circuit for providing information to the display, wherein the control circuit is responsive to detected motion to perform at least one of a pan or zoom of information provided to the display, wherein the pan and/or zoom correspond to a direction and velocity of the detected motion.

2. The electronic equipment of claim 1, wherein the transducer is operable to generate a motion signal that corresponds to acceleration and/or deceleration of the electronic equipment, and the control circuit is operable to determine a velocity of the electronic equipment from the motion signal.

3. The electronic equipment of claim 1, said transducer comprising a signal conditioning circuit to filter out signals representing motion not representative of intended motion of the electronic equipment.

4. The electronic equipment of claim 3, said signal conditioning circuit comprising a low pass filter.

5. The electronic equipment of claim 1, further comprising a motion signal processing circuit operative to provide a motion signal indicative of duration of the motion, amplitude of the motion, and/or frequency of the motion.

6. The electronic equipment of claim 5, wherein the motion signal processing circuit includes at least one of a low pass filter, a threshold detector, an amplitude detector or a frequency detector.

7. The electronic equipment of claim 1, said transducer comprising an accelerometer, a velocimeter or a signal detector.

8. The electronic equipment of claim 1, said transducer operable to detect at least one of acceleration, position, rotation or proximity.

9. The electronic equipment of claim 1, wherein the detected motion is relative to an orientation of the electronic equipment.

10. The electronic equipment of claim 1, wherein at least one of the pan or zoom motions is user configurable.

11. The electronic equipment of claim 10, wherein user configurable includes at least one of defining motion along each axis to correspond to a pan or zoom function;

and adjusting pan and/or zoom rates.

12. The electronic equipment of claim 1, wherein said electronic equipment is a mobile phone.

13. The electronic equipment of claim 1, wherein said electronic equipment is at least one of a personal audio device, a personal video device or a personal digital assistant.

14. A method of viewing a virtual image on an electronic equipment display, comprising:

moving the electronic equipment;

detecting such moving; and

in response to said moving of a prescribed character, panning and/or zooming the virtual image on the display, wherein said panning and/or zooming corresponds to a direction and velocity of the detected moving.

15. The method of claim 14, further comprising panning and/or zooming on the virtual display in proportion to said velocity and direction.

16. The method of claim 14, further comprising conditioning the detected motion to filter out signals representing motion not representative of intended motion of the electronic equipment.

17. The method of claim 14, said prescribed character including at least one of acceleration, velocity, direction, directional change or rotation.

18. The method of claim 14, further comprising enabling or disabling motion detection via a user input.

19. The method of claim 18, wherein enabling or disabling motion detection via a user input includes pressing and holding a key of the mobile phone to enable motion detection.

20. A computer program operable in electronic equipment, said electronic equipment including a display for viewing information, comprising:

code to operate the electronic equipment to detect the character of motion of such electronic equipment; and

code for causing information to be panned or zoomed on the display, said panning and/or zooming corresponding to the detected character of motion, wherein said panning and/or zooming corresponds to a direction and velocity of the character of motion.

21. An electronic equipment, comprising:

a display for viewing a virtual page;

a transducer operable to detect motion of the electronic equipment; and

a control circuit for providing information to the display, wherein the control circuit is responsive to detected motion to perform at least one of a pan or zoom of information provided to the display, wherein said pan or zoom is substantially continuous with the detected motion.
