Abstract

An information display apparatus with proximity detection performance contains a display device that displays image information, a sensor constituted of plural detection electrodes, and an adjusting device of detection resolution that adjusts the detection resolution to be detected based on a distance between the sensor and an object that is contacted to any one of the detection electrodes.

Claims

1-20. -20. (canceled)

21. A display control method comprising the steps of:

detecting a three dimensional spatial position of an object opposite to a surface of a sensor; and

controlling image information on a display surface in motion and rotation direction based upon a detected locus of the spatial position of the object.

22. The method according to claim 21, wherein the spatial position of the object relative to the surface of the sensor includes first, second and third detection spaces, the first detection space located between first and second predetermined distances from the surface of the sensor, the first predetermined distance being further from the surface of the sensor than the second predetermined distance, the second detection space located between the second predetermined distance and a vicinity of the surface of the sensor, and the third detection space indicating a contact point on the surface of the sensor.

23. The method according to claim 22, wherein if the object rotates in the second detection space, display of the image information is controlled so that the image information is rotated in synchronism with the rotation direction and rotational speed of the object along a same direction.

24. The method according to claim 23, wherein the image information is arranged in a middle of the display.

25. The method according to claim 21, wherein the image information is controlled in size based upon the detected spatial position of the object.

26. The method according to claim 21, further comprising the step of adjusting detection resolution based on the detected spatial position of the object.

27. The method according to claim 21, further comprising the step of adjusting detection sensitivity of the sensor based on the detected spatial position of the object.

29. The method according to claim 21, wherein a user can control selection and display of image information based on user control of the object.

30. The method according to claim 26, wherein as the object approaches the surface of the sensor, the detection resolution is successively switched from a highest level to a lowest level based on a distance between the sensor and the object.

31. An image display apparatus comprising:

a sensor detecting a three dimensional spatial position of an object opposite to a surface thereof; and

display controller controlling image information on a display surface in motion and rotation direction based upon a detected locus of the spatial position of the object.

32.
