Sounds come out.
When you push Run button, the Sounds in the training field displayed on the monitor will start to move and play sounds. Please adjust sound volume to listen comfortably.
The grid in the training field monitor are 5 m/div. Upper side is south, and left side is east. The crossing point of the south-north and east-west axes is the origin of the training field. The yellow dot surrounded by the yellow circle stands for the head position of the Trainee in the training field. The yellow short line coming out from the yellow circle stands for the head direction of the Trainee in the training field. The red dots stand for sources of the Sound. The orange thick lines stand for the Walls that reflect and insulate the sounds.
The blue lines stand for the sound lines (sound paths from the Sound to the Trainee). If the sound line is interrupted by the Wall, the blue circle will appear at the interruption point. This shows that the sound is insulated by the Wall. The gray fat lines stand for the Roads, and the purple dots stand for the Marks. The Roads and the Marks do not influence on the sound propagations.
The sounds presented through the headphones are reproduced the sounds that may be heard by the Trainee in the training field in 3-D manner. When the Trainee moves or turns in the training field, the presented sound will also change. The Doppler effect that occurs on the moving sound sources, and the obstacle perception that occurs when the Trainee approach the Wall (in this case, the Wall color changes from orange to white) are also reproduced.
In order to move the Trainee in the training environment, you can use mouse, Wii® Remote Plus Controller™, and GPS. The followings are the explanations of their roles. The explanations of method to use them are skipped here.
- Mouse can move the Trainee in the training field displayed on the monitor directly. It is used when the instructor moves the trainees and presents the sounds to him/her.
- Wii® Remote Plus Controller™ can move the Trainee in the training field as the same motion as the trainee's head motion measured by it fixed on the head (headphones). It is used when the trainee listens to the sounds with walking and orienting his/her head by him/herself.
- GPS can also move the Trainee in the training field as the same motion as the trainee's motion measured by it carried by the trainee. It is mainly used when the trainee walks long distance. It must be used with mouse or Wii® Remote Plus Controller™ because it cannot measure the head orientation.
