About this training


This document establishes the requirements and recommendations for image contents and electronic
display systems to reduce visually induced motion sickness (VIMS), while viewing images on electronic
This document is applicable to electronic display systems, including flat panel displays, projectors with
a screen, and virtual reality (VR) type of head mounted displays (HMDs), but not including HMDs that
present electronic images on/with real-world scenes.
NOTE 1 This document assumes the images are viewed under appropriate defined conditions. See Annex B for
the appropriate viewing conditions.
NOTE 2 This document is useful for the design, development, and supply of image contents, as well as
electronic displays for reducing VIMS.
NOTE 3 ISO 9241-392[3]
provides guidelines for stereoscopic 3D displays, of which the methods are also used
in HMDs.
NOTE 4 The International Telecommunication Union (ITU) generally sets the standards for broadcasting.
