In the example of FIG. 1, the floating body 1 is provided with a propeller 1b so that the floating body 1 can be moved back and forth, left and right, rotated about a vertical axis, and moved up and down. Alternatively, the floating body 1 may be towed by a drone, or may be moved by a wire drive mechanism installed on the ground.

浮遊体１を屋外に設置してもよいが、風の影響を受けにくいアミューズメント施設内、商業施設内、工場内、スポーツ競技場内、劇場内、パーティ会場内等、屋内に設置するのが好適である。また、現場にいる特定の人（司会者、歌手等の芸能演技者、プレゼンテーションのプレゼンター、政治家、企業幹部等）の近傍に浮遊体１を設置してもよい。この場合、この特定の人の移動に合わせて浮遊体１を移動させてもよい。 Although the floating body 1 may be installed outdoors, it is preferable to install it indoors such as amusement facilities, commercial facilities, factories, sports stadiums, theaters, party venues, etc., where it is not easily affected by wind. be. Also, the floating body 1 may be installed near a specific person (a moderator, an entertainer such as a singer, a presenter of a presentation, a politician, a company executive, etc.) on site. In this case, the floating body 1 may be moved according to the movement of this specific person.

計測器２は浮遊体１の位置および／または姿勢をリアルタイムで計測する。計測結果は投影装置３および移動機構４に通知される。なお、計測器２による計測結果を用いるのではなく、気球の位置あるいは姿勢を既知のタイムテーブルとして予め投影装置３が把握しておいてもよい。浮遊体１の位置あるいは姿勢は以下に説明する投影装置３および移動機構４によって用いられる。 The measuring instrument 2 measures the position and/or attitude of the floating body 1 in real time. Measurement results are notified to the projection device 3 and the moving mechanism 4 . Instead of using the measurement result by the measuring device 2, the projection device 3 may grasp the position or attitude of the balloon in advance as a known timetable. The position or attitude of the floating body 1 is used by the projection device 3 and moving mechanism 4 described below.

投影装置３は、例えばプロジェクタやスキャニングレーザによる描画装置であり、浮遊体１の平面１ａに映像を投影する。望ましくは、投影装置３は浮遊体１の位置や姿勢に応じた映像を投影する。例えば、投影装置３は、ズームレンズや縦横比補正機構を有しており、浮遊体１の位置や姿勢に応じて、浮遊体１の平面１ａに投影される映像に歪が生じないよう予め補正した映像を投影する。あるいは、投影装置３は投影方向が可動であり、浮遊体１が位置あるいは姿勢を変えても安定した映像を投影する。 The projection device 3 is, for example, a drawing device using a projector or a scanning laser, and projects an image onto the plane 1a of the floating body 1 . Desirably, the projection device 3 projects an image corresponding to the position and posture of the floating body 1 . For example, the projection device 3 has a zoom lens and an aspect ratio correction mechanism, and corrects in advance so that the image projected on the plane 1a of the floating body 1 is not distorted according to the position and posture of the floating body 1. projected the image. Alternatively, the projection device 3 is movable in the projection direction, and projects a stable image even if the floating body 1 changes its position or posture.
