PROBLEM TO BE SOLVED: To always provide a video having the sufficient visual field angle to a viewer regardless of the movement of a rocking base by installing plural plane screens so that they may surround space in which the rocking base is installed. SOLUTION: Projectors 100a to 100d respectively project images to back projection type screens 101A to 101D. The rocking base 102 rocks back and forth, right and left and up and down. The shape of the screens 101A to 101C is a rectangle of the same size, and the shape of the screen 101D is a square where the long side of another screen is set as one side. The projector 100d projects a video only in a rectangular area 203 in front of the rocking base 102, which seems to be important for the viewer. The viewer sits on the seat part of the rocking base 102 and views the video connected to be one as a whole projected to the screens 101A to 101D. The viewer senses acceleration or force acting on the body of the viewer as bodily sensation by the motion of the rocking base 102 synchronizing with the video. |
