A contents distribution system for a simulation ride system has a seat rocking unit, a video unit, an acoustic unit, and a simulation ride control apparatus. The simulation ride control apparatus has the simulation ride system controlling operations of the seat rocking unit, the video unit, and the acoustic unit by using content data, and a distribution apparatus for a ride contents administration center. The distribution apparatus for the ride contents administration center distributes the content data and the simulation ride control apparatus receives the distributed content data.

Contents distribution system for simulation ride system, distribution apparatus for ride contents administration center, simulation ride control apparatus and computer software

In a VR motion producing apparatus and an apparatus, comprising: a reception unit for receiving a presently projected picture frame No. from a picture apparatus; a detection unit for detecting a frame No. of operation data of a motion base presently executed by a motion base; a difference unit for comparing the picture frame No. with the motion frame No. to calculate a difference between them; a calculation unit for calculating an operation velocity of a motion base so as to correct this difference value; and a synchronization unit for reducing the difference between the picture frame No. and the motion frame No. for operating the motion base from the calculated velocity, a simulation rider transporting apparatus is featured by that an object to be controlled is a dynamic object; a motion model conversion unit is an apparatus for converting a motion model of a dynamic object to be controlled into a motion model of a motion base having a finite stroke, and furthermore contains two crank arms whose one ends are coupled to an elevation unit, a motor equal to a drive unit for changing an angle &ldquo;&prop;&rdquo; between the two crank arms into a preselected value to hold this changed angle, and a speed reducing machine; and a crank rod is coupled to a rider containing base while having a rotation free degree along 3 axial directions.

VR motion base control apparatus and it's supporting structure

A simulation rider transporting apparatus includes a seat having means for constraining an attitude of a rider mounted on a first base and having a second base positioned under the first base. Elevation means for elevating the first base include two cranks which are arranged opposite to each other between the first and the second base. Each of the cranks has crank arms with each crank arm having one end coupled to the second base. A crank rod is provided for coupling the other end of each crank arm to the first base. Drive means are provided for changing a relative angle between the two crank arms to a predetermined value and for holding the changed relative angle.

A VR motion producing apparatus includes a dynamic object to be controlled, a motion base having a finite stroke and motion model converting means for converting in a real time a motion model of a dynamic object to be controlled which is moved within a virtual reality space constituted by computer graphics into another motion model of the motion base having a finite stroke. The motion model converting means includes means for converting coordinate data of the motion model of a dynamic object to be controlled into coordinate data of the motion model of the motion base.

In accordance with levels of skillfulness of operators, guidance of a robot teaching apparatus is automatically changed for facilitated use by beginners and skilled operators. Teaching is performed through an interactive procedure with the aid of a display of message for manipulation guidance and a menu for input selection. A key manipulation path is automatically determined on the basis of various experience factors. For a skilled operator, operation up to generation of a final function display is executed in an automated manner.
