Abstract

Apparatus and method generate interactive signal for a moving article such as an airplane model. The airplane model is provided with a human-sensible interactive signal source; and the moving status of the air plane model such velocity is detected to generate a movement parameter. The movement parameter is operated with a frequency-dependent conversion function to obtain a first interactive data. A second interactive data is generated when a trace of the moving article is matched with a default pattern. A third interactive data is generated when the velocity along at least one dimension exceeds a threshold value. The interactive signal source, such as loudspeaker or lamps, is selectively driven by one of the interactive data to generate a movement-dependent audiovisual effect. Therefore, the apparatus and method generating interactive signal for moving article can provide enhanced amusement effect for user.
