Abstract: A processing apparatus generates a command in accordance with a size of the coordinate input area and a distance between two touch inputs on the coordinate input area. When a distance between two touch inputs on a first coordinate input area larger than a second coordinate input area changes to a first distance, a command corresponding to a second distance longer than the first distance is generated. When a distance between two touch inputs on the second coordinate input area smaller than the first coordinate input area changes to a third distance, a command corresponding to the third distance is generated.

Abstract: The sensor unit of each of a first bar housing unit and second bar housing unit is moved. The moving amount is measured and stored. The distribution of a light amount received by the light receiving unit of the sensor unit of each of the first bar housing unit and second bar housing unit is detected, and whether the moving amount is appropriate is determined based on the detection result. A calculation value used when the coordinates of the pointed position in the coordinate input effective region are calculated based on variations of the light amount distribution is corrected by using the moving amount stored when it is determined that the moving amount is appropriate.

Abstract: A user interface technique with excellent operability for displaying an object to be selected upright for an operator who operates a display screen of a display device from any direction. For this purpose, when the operator touches the display screen with his/her index finger, menu icons are displayed on a circumference with the touch position as a center, and with the central position of the circle as a lower position, at equal intervals. At this time, when the operator touches the display screen with his/her thumb while touching the display screen with his/her index finger, it is determined that the operator exists on an extension line on the thumb touch position side defined with the two touch positions. Then the respective menu icons are rearranged so as to be displayed upright from the operator.

Abstract: According to the present invention, even if a plurality of operators perform gesture operations in three-dimensional space, the three-dimensional spatial gesture of each operator is accurately associated with the target object of the three-dimensional spatial gesture. For this, a projector displays at least one selection-target object on an upper surface of a table. When a pointer operated by an operator comes in contact with the upper surface of the table, a two-dimensional coordinate detecting apparatus detects the contact position, and determines which object has been designated by the operator. In this stage, among pointers detected by a three-dimensional coordinate detecting apparatus, a pointer having a position closest to the contact position is determined, and the pointer determined to be the closest is decided as a tracking target. Thereafter, the tracking-target pointer is tracked by the three-dimensional coordinate detecting apparatus to determine the operator's gesture pattern.
