Simulation device

Claim 1

A simulation device, comprising: user occupancy means; a yoke as a support on which said user occupancy means is mounted with freedom for rotational movement about a first axis extending through said occupancy means; a structure having a base on which said yoke is mounted with freedom for rotational movement about a second axis generally normal to the first axis and extending through said occupancy means; prime mover means for moving said occupancy means at least in rotation about said first axis and said yoke in rotation at least about said second axis; manual control means, carried by said occupancy means, for causing said prime mover means to drive said occupancy means and said yoke in a controlled manner at least in rotation respectfully about said first axis and said second axis; a VDU carried by said occupancy means, said VDU being capable of displaying a computer generated picture responding to picture signals fed thereto; sensor means for sensing rotational movement of said occupancy means, said sensor means comprising a first sensor directly responsive to rotation of said user occupancy means relative to said yoke and a second sensor directly responsive to rotation of said yoke relative to said base structure so that there is one sensor for each axis of rotation thereby permitting said sensor means to be responsive to all movement of said user occupancy means, said sensor means not forming a part of, and not being responsive to, said manual control means; and a computer which is fed from said sensor means and which generates picture signals fed to the VDU so as to cause the display to scroll in synchronized relationship to said rotational movements of said occupancy means and said yoke respectively about said first axis and said second axis, said movement including those produced by the use of said manual control means.
