Pointing information processing apparatus with pointing function
First Claim
1. An input/output integrated information processing apparatus including a display device and a substantially transparent input tablet having an input surface placed on a display surface of said display device for outputting a pointing coordinate which is a coordinate on said input surface pointed to by a user utilizing a finger or an indicator, comprising:
- indication direction extended point determining means for determining an indication direction extended point coordinate, which is an intersection of an extended projection of the finger or the indicator intended by the user and the display surface of said display device, from the pointing coordinate output by said input tablet and a predetermined value by utilizing information including the set diameter of a tip of the user'"'"'s finger or the indicator, the set tilt angle of the user'"'"'s finger or the indicator in a direction normal to said input surface, and said pointing coordinate; and
display processing means for displaying a point, by utilizing a cursor, on the display surface of said display device, corresponding to the determined indication direction extended point coordinate so as to distinguishably display the determined indication direction extended point coordinate on said display device.

Abstract
An integrated information processing apparatus is provided with a display device and a generally transparent input tablet having an input surface placed on a display surface of the display device for outputting a pointing coordinate which is a coordinate on the input surface pointed by a user'"'"'s finger or an indicator. The apparatus includes a circuit for determining an indication direction extended point coordinate from the pointing coordinate output by the input tablet and a predetermined value, and a display processing section for displaying a point on the display surface of the display device corresponding to the determined indication direction extended point coordinate so that it is distinguishably displayed on the display device.
