In FIG. 5C, the arrow points to Rigel at Orion. After that, the operator touches the touch panel 12 at the position of the tip of the arrow displayed on the display 11.
With the pointing pen 13 (step S6: YE
S). In this way, the position on the touch panel 12 which is touched by the pointing pen 13 is calculated by the pointing device control device 10 (step S7). Based on the position thus calculated, a point is displayed at the position on the display 11 corresponding to the position. The position calculated in step S7 is also transferred to the video projector 6 (steps S9, 10), and the position on the dome 1 corresponding to the position struck by the pointing pen 13 on the dome is also transferred to the video projector. A point is projected by 6.

Then, when the touch panel 12 is continuously traced by the pointing pen 13, step S6 is performed.
The process from S10 to S10 is repeatedly executed. This allows
As shown in FIG. 5D, the pointing pen 13
A locus traced by the touch panel 12 is displayed as lines on the display 11 and the dome 1. Therefore, by explaining how to connect the stars in the constellation while continuously tracing the touch panel 12 with the pointing pen 13, the spectator can see the locus traced by the stars. For this reason,
Audiences are easy to understand how to connect stars, and commentators are also easy to explain.
