    • DESCRIPTION OF THE PREFERRED EMBODIMENTS
  • In FIG. 1 an acceleration on a mass located in [0012] simulator room 70, such as a person setting in acceleration seat 140, is represented by net simulator acceleration vector 180, which varies in magnitude and varies in direction relative to simulator room 70. The variation in magnitude is produced as a consequence of the varying angular rotation w of the rotating base 40. The variation in direction r2 is produced by rotating simulator room support platform 90 relative to rotating base by causing simulator 1st angular orientation motor 50. The variation in direction r1 relative to simulator room 70 is produced by causing simulator 2nd angular orientation motor 80 to rotate simulator room 70 around room rotating axis arms 100 a and 100 b.
  • The variation in magnitude of the simulator vector can also be accomplished by varying the distance d which is distance that the simulator is from the center of rotation around [0013] platform motor 20 and the simulator room's center of mass 70. This is accomplished by room screw adjust drive 150.
  • In FIG. 2 an [0014] acceleration seat 170 is secured to simulator room 70. The simulation video screen 190 projects a simulated event which has an associated simulated acceleration vector S associated with it in time. The simulated event may be a prerecorded on video tape, an animated film or a computer program etc..
  • In FIG. 3 a reference frame XYZ is displayed which is rotating relative to some other reference frame. A simulated acceleration vector S is the composite of the gravitational vector G and the centrifugal force vector A i.e., S=A+G. [0015]
  • FIG. 4 illustrates the resultant transformation S to S′ if one angle of orientation is changed by angle r[0016] 1, i.e., the x axis of XYZ is rotated an angle r1 about the z axis. The simulated acceleration vector appears to change directions in the frame XYZ. If a rotation is then produced by rotating an angle r2 around the Z axis of the XYZ frame then an orientation of any angle can be obtained.
  • [0017] Computer 140 interfaces to the motors and video screens through inputs 120 and outputs 130. A joy stick (not shown) could be interfaced to the computer through inputs 120 and an existing video game could be modified to produce an acceleration vector parameter to be used by the computer to control the simulation acceleration vector S. An acceleration sensor could be interfaced as an input device to provide feed back as to the actual acceleration produced on a mass within the simulator room.
  • While my above description contains many specificities, these should not be construed as limitations on the scope of the invention, but rather as an exemplification of one preferred embodiment thereof. Many other variations are possible. The scope of the invention should be determined not by the embodiment(s) illustrated, but by the appended claims and their legal equivalents. [0018]
