Abstract:
1. A method for pointing to an object displayed on a touchscreen using an information processing apparatus, the information processing apparatus being connected to the touchscreen so that the touchscreen and the information processing apparatus can communicate data to each other, the touchscreen having a display function, the method comprising: calculating coordinates of a point P, the point P being a position on a surface of the touchscreen corresponding to a position of a fingertip of a user located above the surface of the touchscreen; calculating a vertical distance R between the surface of the touchscreen and the fingertip; calculating coordinates of a point Q of a line segment OQ, the line segment OQ extending in the same direction as a line segment OP connecting an origin O on the surface of the touchscreen and the point P, the line segment OQ having a length that is proportional to the vertical distance R; and in response to an object being displayed at the coordinates of the point Q, determining, by a processor, that the object has been pointed to.
