Method to connect

If you want to use GPS, it must be connected to your computer in advance to start WR-AOTS™ Ver. 2.08 application software.

Generally, the USB-connectable and NMEA-formatted GPS can be used. In order to connect GPS to your computer, please follow the instruction on the manual of GPS.

If the settings are required at/after connection, please set as the follows:

  • Serial communication
    • Bit rate 4,800
    • Data bit 8
    • Parity none
    • Stop bit 1
    • Handshake none
  • Sampling 1 Hz
  • Sentence GGA

Please make sure that your GPS can measure the position by the testing software attached to GPS.

* In order to measure the position, the radio waves from at least 4 Satellites are required to be received. Thus it can be used only in the outdoor where sky can be looked over.

Method to mount

This section explains how to mount GPS on the trainee.

GPS is used to measure the trainee's head position with respect to the ground. However, it is not used to measure the head orientation. Thus, it is not needed to be mounted on the trainee's head. It can be mounted on the near place from head (e.g. on the shoulder).

This figure shows that GPS is on the left shoulder of the trainee with headphone.

Method to calibrate

GPS must be calibrated in advance to run.

* If you use Wii® Remote Plus Controller™ as well, it also must be calibrated. The procedure of Wii® Remote Plus Controller™ calibration is almost the same as GPS. Please refer to How to calibrate Wii® Remote Plus Controller™.

  1. Confirm connection by GPS Message window.

    Please start WR-AOTS™ Ver. 2.08 after GPS is connected to your computer. When you start the application, you will find that a message window of GPS that says GPS found: COM** (** is tow-digits number). Please push OK button.

    This figure shows pushing OK button on the message window saying : GPS found : COM**.

    If the massage says GPS Initialize failed!, the application cannot use GPS . In this case, please push OK button and also Quit button to quit the application.

    This figure shows pushing OK button on the message window saying : GPS Initialize failed! This figure shows pushing Quit button.

  2. Check GPS checkbox.

    Please make sure that GPS checkbox is checked on the Main window.

    This figure shows checking GPS checkbox.

  3. Make trainee stand still at the ready to start training.

    Please make the trainee stand still at the ready to start the training. The position and orientation of the trainee's head in this time will be the initial position (i.e. the origin of the training field).

    The Trainee in the training field is supposed to face south direction as an initial orientation. In calibration, the trainee must face south as accurate as possible by measuring the orientation with compass.

    This figure shows that the trainee with GPS and headphone is facing south and is standing still at the ready to start the training. This figure shows that the head position and orientation of the Trainee in the training field is the initial position (i.e. the origin of the training field) and the south direction (i.e. upper side of the training field).

  4. Calibrate now.

    If you are ready, please push Calibration button. The question window to ask Calibration OK? will open. Please push OK button to start the calibration. It takes about 2 s to calibrate. Please do not move GPS during the calibration.

    This figure shows pushing Calibration button. This figure shows pushing OK button on the question window.

How to navigate

In order to navigate the Trainee in the training field, operations are available when the status is Run (the Run button was pushed and the Action indicator shows Run). The GPS navigation includes Parallel movement only.

This figure shows pushing Run button This figure shows that the Action indicator shows Run.
  • Parallel movement (change place)

    When the Stable operation mode is unavailable and GPS indicator shows red (i.e. 4 and more Satellites can be received and positioning is available), if GPS moves, the Trainee in the training field moves as same direction and distance as the movement of GPS. In this case, the directions of the head and the movement are not needed to be the same (i.e. walking sideway or diagonally is available)

    * Even if the receivable Satellites are 4 and more, when the positioning error is too large, GPS indicator does not show red.

    * The motion of the Trainee in the training field may be different from the actual motion of GPS because of the measurement error included in results of the acceleration sensor in GPS. In this case, you are recommended to turn on the Stable operation mode, and not to use GPS.

    This figure shows that the GPS indicator shows red and number of the receivable Satellites are 4.
    This figure shows that GPS moves in parallel. This figure shows that the Trainee in the training field moves in parallel to the different direction from the head direction on the monitor.
