Method and program for driving information processing device

摘要

A method for driving an information processing device which is adaptable to a wider variety of input methods is provided. The coordinates of an operating body at a starting point in the XYZ space and the coordinates of the operating body at an ending point in the XYZ space after a certain period of time are obtained, and the Z coordinate at the ending point and the movement distance on the X-Y plane in the certain period of time are calculated. Then, a signal is output only in the case where both the distance from an operating surface to the operating body in the vertical direction and the movement distance in the horizontal direction exceed the respective threshold values. In this manner, input operation can be performed by a three-dimensional motion, which includes movement of the operating body in the vertical direction as well as in the horizontal direction.

主权项

1. A method for driving an information processing device comprising a display surface displaying an image and an operating surface touched or approached by an operating body, the method comprising the steps of:
sensing a distance from the operating surface to the operating body in a vertical direction; obtaining first coordinates of the operating body when a vertical coordinate among the first coordinates is less than or equal to a first threshold value: obtaining second coordinates of the operating body after a predetermined period of time after obtaining the first coordinates; and outputting an image switching signal only when a vertical coordinate among the second coordinates is greater than the first threshold value and a movement distance of the operating body in a horizontal direction calculated from the first coordinates and the second coordinates is greater than a second threshold value.
