1. An information processing apparatus comprising:
- a display device;
pointed position detecting means for detecting a specified position by a touch operation of a pointing device on a screen of the display device;
sensor means for detecting a position of the pointing device when the pointing device is not in contact with the screen of the display device; and
control means for recognizing the touch operation detected by the pointed position detecting means and controlling the information processing apparatus in accordance with the recognized touch operation and the position of the pointing device detected by the sensor means,wherein the sensor means includes at least four sensor means each disposed at a position corresponding to a different quadrant or corner of the screen and each of the at least four sensor means is inclined at a non-zero angle with respect to the screen, andthe sensor means recognizes a direction of movement of the pointing device when the pointing device is not in contact with the screen which includes at least recognizing a circular movement of the pointing device along a plane that is parallel with respect to the screen when the pointing device is not in contact with the screen.

15. An information processing method, implemented on an information processing apparatus having a display device, comprising:
-
detecting a specified position by a touch operation of a pointing device on a screen of the display device; detecting, with a sensor unit, a position of the pointing device when the pointing device is not in contact with the screen of the display device; and recognizing the touch operation and controlling the information processing apparatus in accordance with the recognized touch operation and the position of the pointing device detected by the sensor unit, wherein the sensor unit includes at least four sensors each disposed at a position corresponding to a different quadrant or corner of the screen and each of the at least four sensor means is inclined at a non-zero angle with respect to the screen, the method further including recognizing, with the sensor unit, a direction of movement of the pointing device when the pointing device is not in contact with the screen which includes at least recognizing a circular movement of the pointing device along a plane that is parallel with respect to the screen when the pointing device is not in contact with the screen.
