Abstract

A method for producing a simulator program includes: generating video and audio information from a camera mounted on a vehicle to be simulated; measuring motion data according to a pose change of the camera; processing the motion data and generating motion effect data comprising position and rotary motion information including acceleration and angular velocity for each axis x, y, and z; separating a motion unit from the motion data to generate a motion unit data stream and synchronizing the motion unit data with video/audio data; recognizing and determining a motion unit representing position and rotary motion information for each axis based on the motion unit data stream; and generating a control unit representing position and rotary motion information suitable for a simulator having a fixed degree of freedom and a fixed movement space, based on the motion unit, and producing a control unit shift function and composite control data.
