The spaceship is not visible.

①The controller (either right VR or left VR) configured in the clinical interface is not in your field of view.

The spaceship will be presented to the dominant eye. Keep the hand controlling the spaceship within the visible field of view and move the controller accordingly.

②Your controller is not within the sensor area.

Hold controllers in both hands, raise them to eye level, and confirm that the spaceship is visible.

③Your hands are protruding beyond the sensing area.

Stand in the center of the sensing area, facing forward with the correct posture, and press the "Recenter" button. Move both hands at eye level, and if they are still not detected, please repeat this procedure.
