In operation S420, the motion control device determines whether or not the conversion point data (x, y, z, yaw, pitch, roll) in the current frame matches a pattern code corresponding to the basic motion pattern among a plurality of previously stored pattern codes . For example, when the derivative value of the x, y, and z values of the conversion point data is 0, it matches the pattern code of the movement pattern (movement in a specific direction) among the basic motion patterns (the derivative of x, y, do.

If it is determined that the conversion point data does not coincide with the pattern code corresponding to the basic motion pattern, the motion control device repeats operation S410.

If the conversion point data matches the pattern code corresponding to the basic motion pattern as a result of the determination, the motion control device calculates the coincidence rate of the basic motion pattern corresponding to the pattern code coinciding with the conversion point data in operation S421. For example, the motion control device compares the conversion point data with pattern data that is predefined by a predefined pattern equation in relation to the basic motion pattern. The motion control device calculates the coincidence rate between the conversion point data and the pattern data using the result of comparing the conversion point data and the pattern data.

In operation S422, the motion control apparatus can use the calculated result to store the base motion pattern compared with the start time and end time of the interval in which the matching rate is higher than the threshold value in the memory as " under consideration pattern " (candidate motion pattern) . For example, the motion control device can store a single basic motion pattern as well as a plurality of basic motion patterns in memory as " under consideration ". For example, the motion control apparatus can store both the movement pattern having the specific start time and the specific end time and the italic pattern having the same start time and the same end time as " pattern under consideration ".

In operation S450, the motion control device determines whether or not the transformation point data in the current frame matches the composite pattern code corresponding to the composite motion pattern.

If the conversion point data is inconsistent with the complex pattern code as a result of the determination, the motion control device designates the ending time of the basic motion pattern and the basic motion pattern in progress (stored as " under consideration " "Can be stored in memory.

If the conversion point data matches the composite pattern code as a result of the determination, the motion control device determines whether the composite motion pattern corresponding to the composite pattern code matching the conversion point data is an ongoing pattern in operation S46O.

If it is determined in step S462 that the composite motion pattern is not an ongoing pattern, the motion control device may set the start time of the composite motion pattern and the composite motion pattern and store the motion pattern as a " under consideration pattern ".

If it is determined that the combined motion pattern is an ongoing pattern, in operation S461, the motion control apparatus may add the combined motion pattern to the existing ongoing pattern.

In operation S470, the motion controller may calculate a match rate of at least one " under consideration pattern " stored so far to the current conversion point data using at least one " under consideration pattern " .

In operation S480, the motion control device determines whether a new motion control input is present.

If a new motion control input exists as a result of the determination, the motion control device performs operation S410.

If, as a result of the determination, there is no new motion control input, at step S481 the motion control device determines, based on the match rate of at least one " under consideration pattern " It is possible to select a similar motion pattern having the highest matching rate among the " pattern under consideration ".

When the operation S481 is performed, the motion control device can use the selected similar motion pattern to control the motion of the chair in which the viewer is seated.
