DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS First, a basic configuration of the present invention will be described with reference to FIGS. 1 and 2 show the configuration, and FIG. 3 shows a block diagram of the control circuit. In the dome 1, a stellar projector 2 is installed at the center thereof. The star projector is connected to the console 4 via the computer 3, and according to an instruction from the console 4, the planetarium control device 3
Controls the stellar projector 2. Next to the console 4, a pointing device 5 according to the present invention is installed. In the dome 1, a video projector 6 is also installed.

The details of the pointing device 5 are shown in FIG. As shown in the drawing, the pointing device 5 generally includes a pointing device control device 10 and a display 11 mounted on the pointing device control device 10. A touch panel 12 is arranged on the front of the display 11.

FIG. 3 shows a control circuit. When the commentator pokes an arbitrary position on the touch panel 12 of the pointing device 5 with the pointing pen 13, data relating to coordinates on the touch panel 12 of a point pierced by the pointing pen 13 is input to the pointing device 10. The pointing device control device 10 transfers a video signal to the display 11 and the video projector 6 based on the coordinate data input from the patch panel 12. The display 11 displays a dot on the screen of the display 11 at a position corresponding to the position where the pointing pen 13 is touched on the touch panel 12, based on the video signal transferred from the pointing device control device 10. Similarly, the video projector 6 displays a dot on the dome 1 at a position corresponding to the position where the pointing pen 13 is touched on the touch panel 12 based on the video signal transferred from the pointing device control device 10.

Next, how to connect stars in Orion will be described with reference to FIGS. When the production date and time and the viewpoint position are input from the console 4, the position of the star at the input date and time and position is calculated (steps S1 and S2). The star position thus determined is converted into dome coordinates, and the star projector 2 is driven according to the result (steps S3, S4).

FIG. 5A shows the state of the dome 1 at this time. In the figure, reference numeral 20 denotes a range in which an image from the video projector 6 is projected on the dome 1. In this figure, the celestial body (Orion) to be described is not within the projection range 20, so the Orion must be introduced into the projection range 20. For this reason, by operating the console 4, the star projector 2 is changed in longitude, azimuth, and diurnal motion to move Orion horizontally.
(A)). Subsequently, by operating the console 4, the latitude of the star projector 2 is changed to move the constellation Orion vertically, and the constellation Orion is introduced into the projection range 20 (FIG. 5).
(B)).

The completion of the above processing is indicated by the console 4
(Step S5), the operation shifts to operation with the pointing device 5. First, an arrow is displayed on the display 11 and projected on the dome 1 as shown in FIG. The position where the arrow is displayed and projected can be freely moved by operation from the console 4, but the position where the arrow on the display 11 is displayed and the position where the arrow on the dome is projected always correspond. ing. In FIG. 5C, the arrow points to Rigel in Orion. Thereafter, 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 that 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 a position on the display 11 corresponding to the position. Further, the position calculated in step S7 is also transferred to the video projector 6 (steps S9 and S10), and the video projector 6 is placed on the dome at a position corresponding to the position struck by the pointing pen 13 on the dome. A point is projected by 6.

When the touch panel 12 is continuously traced by the pointing pen 13, step S6
To S10 are repeatedly executed. This allows
As shown in FIG. 5D, the pointing pen 13
The locus traced on the touch panel 12 is displayed on the display 11 and the dome 1 by lines. Accordingly, by explaining how to connect the stars of the constellation while continuously tracing the touch panel 12 with the pointing pen 13, the audience can see the trajectory tracing the stars. For this reason,
The audience can easily understand how to connect the stars, and the commentator can easily explain.

<First Embodiment> Next, a first embodiment of the present invention will be described with reference to FIGS. The mechanical configuration of this embodiment is substantially the same as that of the basic configuration.

Step S100 is added between Step S5 and Step S5. That is, the star projector 2 is driven in step S4 based on the star position calculated in step S3, and the star position data calculated in step S3 is transferred to the pointing device controller 10 in step S100. Then, the pointing control device 10 determines a star located within the projection range 20 of the video projector 6, and causes the display 11 to display the star.

FIG. 8 explains the operation in the first embodiment. As shown in the figure, the same star as the star projected on the projection range 20 on the dome 1 is always displayed on the display 11. Therefore, when explaining how to connect the stars of the constellation, the commentator does not need to look at the dome 1 and only has to operate the vice by pointing and looking at only the display 11 on which the same star as the dome is displayed. Therefore, the operation of the pointing device is easy, and the commentator can easily explain.

<Second Embodiment> Next, a second embodiment of the present invention will be described with reference to FIGS. In the first embodiment, the stars located inside the projection range 20 of the video projector 6 are determined by calculation, and the stars are displayed on the display 11 according to the result.
