THREE-DIMENSIONAL INFORMATION HANDLING SYSTEM

摘要

A three-dimensional information handling system includes a display device for indicating a virtual three-dimensional space on a two-dimensional screen, and a position and orientation designating device for designating information of a three-dimensional position and a three-dimensional orientation. A position and orientation measuring device serves to measure the three-dimensional position and orientation information which is designated by the position and orientation designating device. A processing device serves to calculate three-dimensional display information on the basis of the three-dimensional position and orientation information measured by the position and orientation measuring device, and serves to control the display device and the position and orientation measuring device. A cursor is indicated on the screen of the display device. The cursor is moved in accordance with movement of the position and orientation designating device. A figure is indicated on the screen of the display. The figure extends from the cursor. The figure is moved in accordance with the movement of the cursor.
