Information technology for learning, education and training — Human factor guidelines for virtual reality content — Part 1: Considerations when using VR content
This document presents considerations for using VR content in the learning, education and training (LET) domain for reducing reality and virtual reality crossover confusion among users and assisting users to effectively use these emerging technologies. This document addresses VR content that uses a head-mounted display (HMD) in the LET domain. It does not address VR content using immersive technology and does not address augmented reality, mixed or merged reality content.

ISO (the International Organization for Standardization) and IEC (the International Electrotechnical
Commission) form the specialized system for worldwide standardization. National bodies that
are members of ISO or IEC participate in the development of International Standards through
technical committees established by the respective organization to deal with particular fields of
technical activity. ISO and IEC technical committees collaborate in fields of mutual interest. Other
international organizations, governmental and non-governmental, in liaison with ISO and IEC, also
take part in the work.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for
the different types of document should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject
of patent rights. ISO and IEC shall not be held responsible for identifying any or all such patent
rights. Details of any patent rights identified during the development of the document will be in the

Introduction
Virtual reality (VR) technology is expected to be introduced into the world of primary and secondary
[1]
education in the next two to three years. However, there are some concerns, such as health-related
side effects for learners who use VR technology in their development period. These issues can be raised
in any environment that uses VR content.
Concerns related to health conditions:
— Discomfort: When using VR, some people experience symptoms of discomfort, such as dizziness,
headache and nausea. These symptoms are called various terms such as 'VR sickness', 'simulator
sickness', 'motion sickness' and 'cyber nuisance'. When actual physical movement does not occur
with respect to the visual stimulus generated in the virtual environment, discomfort can be caused.
— Eyesight problems: Many devices are located very close to the user's eyes. As a result, some people
feel visual fatigue after wearing them for a long time, and some users experience blurred vision,
diplopia and mechanical near-sightedness.
— Photosensitivity Syndrome: Also known as Pokemon Shock or Nintendo Syndrome, this is a condition
in which seizures (epilepsy) occur due to rapid flashing light stimuli.
— Musculoskeletal disorders due to repetitive tasks: If someone repeatedly takes the same posture for
a long period of time to operate the machine, pain or fatigue can be caused by continuous stimulation
of the musculoskeletal system.
— Hygiene problems: If many people use the same device jointly, or even if one person uses the same
device repeatedly, problems such as infectious disease or skin irritation can occur.
Concerns related to safety:
— Limitations of the user’s field of view: When using a device that blocks physical surroundings from
view, a user may not be able to remain aware of their physical surroundings which can lead to
accidents such as collisions, falling, etc. Even if someone uses a see-through or semi-transparent
device that overlaps a virtual object with reality, such distraction physical surroundings could
increase the risk of having an accident, such as falling.
— Safety accidents caused by confusing reality with the virtual world: Accidents can occur in scenarios
such as users trying to sit or lean against a virtual world chair or wall that does not exist in real life.
Concerns related to social aspects:
— If users cannot distinguish between the real world and the virtual world by excessive immersion
into virtual reality, they may attempt to restart a real-life situation as if they were able to simply
push the ‘reset button’ in VR.
Annex A provides examples of guidelines for users.
