A starry sky reproducing device contains: a ceiling section an inner surface of which has a semi-spherical surface on which a starry sky can be projected; a wall section which has a nearly vertical wall surface contiguous to a lower end section of the semi-spherical surface of the ceiling section; a floor section on which the wall section is installed; starry sky projection means for projecting a starry sky on the semi-spherical surface of the ceiling section, the starry sky projection means being installed near a center of the floor section and near a center of the semi-spherical surface of the ceiling section; a plurality of seats which are installed on the floor section; one or more partial starry sky reproducing means for reproducing details of a part of a starry sky, the partial starry sky reproducing means being installed between the seats and the wall surface, preferably at positions in a proximity of the wall surface; and one or more telescopes through which a detailed image of a part of a starry sky which the partial starry sky reproducing means reproduces can be observed, the telescopes being installed at positions between the seats and the wall surface opposing the partial starry sky reproducing means across the starry sky projection means.

The present invention provides a method of setting light emission control of each light emission tool in an area more easily. The method of setting light emission control of each tool in an area of the present invention includes: a light emitting step of transmitting a freely-selected ID signal (S.sub.n) to a plurality of tools in an area and emit light in response to receipt of corresponding ID signals to cause a tool (E.sub.n) that has received the signal (S.sub.n) to emit light; an imaging step of acquiring a light emission image (E.sub.n) of the area after the signal (S.sub.n) has been transmitted; a determining step of determining a position of the tool (E.sub.n) that emitted light in the area based on the image (E.sub.n); and a storing step of storing the position of the tool (E.sub.n) in the area and the corresponding signal (S.sub.n).
