Data input unit
First Claim
1. A data input unit comprising:
- an input unit for indicating an arbitrary spatial position;
a detecting unit for detecting three-dimensional position information corresponding to the spatial position as an absolute coordinate from said detecting unit;
a processing unit including an operating section for converting the three-dimensional position information into position information represented by a coordinate in a specific plane and a height in an axial direction perpendicularly intersecting to the plane, a memory section for storing the position information converted by said operating section, and an I/O section for outputting display information which is changed according to a size of the height information taken out from said memory section; and
an output unit for displaying a two-dimensional display of the spatial position of said input unit based upon the display information from said processing unit.

Abstract
Three-dimensional position information inputted by an input unit is detected by a detecting unit and is converted into coordinate information in a specific plane and height information in an axial direction perpendicularly intersecting to the plane by an operating section of a processing unit. In the case of a plurality of input units, the information is discriminated per input unit by a discriminating section of the processing unit. The information is stored in a memory section and is taken out from the memory section suitably and is outputted as display information by an I/O section of the processing unit so that display is changed according to a size of the height information. The outputted information is indicated by, for example, a designating graphic on an output unit. At this time, an operator can recognize a distance between the input unit and the detecting unit and discriminate the information according to shades of a color of the designating graphic.
