Inventor: MIURA MASAMI
IPC: G09B9/00
Filed: 2002-01-11
Abstract: <P>PROBLEM TO BE SOLVED: To moderate the magnitude of oscillation of a ship in accordance with needs of a passenger by a simple facility, or to moderate the magnitude of oscillation in a virtual sense.  <P>SOLUTION: The oscillation suppressing device 12 driven by an oscillation frequency with a phase opposite to an oscillation frequency mainly causing seasickness is installed beneath a floor 11 of the ship, and a bed 13 is placed on the floor 11 via an oscillation transmitting part 12a of the oscillation suppressing device 12. By this, amplitude of oscillation propagated to the bed 13 is canceled out and it becomes substantially zero by the oscillation frequency of the ship itself and the oscillation frequency of the oscillation suppressing device 12. Consequently, the passenger 14 does not become seasick even when the oscillation of the ship itself is large. When the oscillation suppressing device 12 is turned off by a switch 17, a landscape image is projected in goggles 15 worn by the passenger 14 or on a ceiling 16. Accordingly, the passenger 14 can experience a virtual reality of comfortable swinging by the projected image even when the oscillation of the ship is large and seasickness can be prevented.  <P>COPYRIGHT: (C)2003,JPO
