[Q&A on the guidelines]
Q: What is the purpose of these guidelines?
A: About the use of a binocular stereoscope by children aged below 13, which has notbeen proved to cause a problem or not, the guidelines are established to provide
location operators with the industry association’s guide they can go by in their selfimposed regulations considering adverse effects on children’s eyesight, thereby
promoting healthy development of the market and creating new applications orincreasing the uses in such fields as education and training.
Q: What are grounds for the guidelines?
A: We have established these guidelines for self-imposed regulations after careful
examinations by experts based on medical knowledge currently available, about theeffects of location-based VR on the development of stereoscopic vision of children,
assuming that location operators control the duration and frequency of the usage of
VR content by stationing attendants.
Q: Why is the usage of VR content allowed for children aged seven or above?
A: Generally, the development of basic stereoscopic vision is said to be completed at
an age of six or seven. We have received advice from a pediatrician. The
pediatrician said, “It is not desirable that children do something that can hinder thedevelopment of stereoscopic vision during the development period.” Based on theadvice, experts carried out careful examinations and came up with these guidelines
for self-imposed regulations. The pediatrician also advised that the user should takebreaks properly even if the development of stereoscopic vision has been completed.
Q: Why do some head-mounted display (HMD) manufacturers set the minimum age touse HMD at 13?
A: Please ask HMD manufacturers about their age limits.
Q: Why are the limits different between HMD manufacturers and Location-based VRAssociation?
A: These guidelines are premised on the assumption that location operators control theduration and frequency of the usage of VR content by stationing attendants. We
will review the guidelines constantly, considering possible effects on customers.

Q: When a device of an HMD manufacturer who explicitly prohibits the usage is used,
are these guidelines not applicable?
A: When a device of the HMD manufacturer who prohibits the usage is used, we do
not recommend that children under the age of 13 use the device. About prohibitionof the usage of individual devices, check their instructions.
Q: If all the HMD manufacturers prohibit the usage, can’t location operators use anyHMD?
A: We do not recommend that children under the age of 13 use a device of the HMD
manufacturer who prohibits the usage. When a location operator is running thefacility the way the HMD manufacturer prohibits, that is done on the operator’s ownresponsibility.
Q: When an accident occurs, with whom does the responsibility lie?
A: These guidelines should be used on each operator’s own responsibility, as theguidelines say. If an accident occurs, the responsibility lies with the operator.
Q: Are these guidelines determinate?
A: These guidelines are based on the latest facts at the time of establishment. If changes
occur in those facts, we will review the guidelines, while considering possible
effects on customers and collecting information extensively.
Q: Is it possible to modify the guidelines and use the modified version?
A: These guidelines are provided as a guide and not legal obligations. We do not forbid
location operators from modifying the guidelines and using them on their own
responsibility while understanding the things to be considered in the guidelines.
Q: Do you inform HMD manufacturers of these guidelines?
A: We are considering sharing information with HMD manufacturers and updating theguidelines. We hope that location operators using these guidelines will also share
information with manufacturers they do business with.
Q: Surely, there was a case of a squint in the 1980s?
A: It is extremely difficult to prove that a squint is caused by a binocular stereo HMD.
It has not been proved until now. Some HMD manufacturers are easing the limits.
The usage with parents’ consent, as stated in these guidelines, is allowed at homeand abroad. No cases have been reported. The case of a squint was reported in the1980s. The accuracy of producing stereoscopic images should have been far lower
than that of the present technology. As it has not been proved that a problem iscaused, we believe we should make a judgment based on the current cases andmedical point of view.

Q: Aren’t there important things to be considered in the usage of VR devices other thanthese guidelines?
A: These guidelines cover precautions to be followed on the usage of VR content bychildren, assuming that general precautions are already observed. Separately, we areworking on general precautions on the VR content usage.
