IEEE Std 3079:2020 pdf download.IEEE Standard for Head-M ounted Display (HMD)-Based Virtual Reality(VR) Sickness Reduction Technology.
IEEE Std 3079 defines the technical requirements that can reduce or control the VR sickness caused by the
HMD-based VR content service. Hence, the VR content service mentioned in this document is considered
HMD-based VR content service by default unless otherwise mentioned. The requirements cover the
followings:
Content design for VR sickness reduction
The framework for VR sickness assessment
The measurement and the network requirements related to motion-to-photon latency for VR sickness reduction
1.2 Word usage
The word shall indicates mandatory requirements strictly to be followed in order to conform to the standard and from which no deviation is permitted (shallequals is required io).’ 2
The word should indicates that among several possibilities one is recommended as particularly suitable, without mentioning or excluding others; or that a certain course of action is preferred but not necessarily required.
The word nzav is used to indicate a course of action permissible within the limits of the standard (may equals is permitted to).
The word can is used for statements of possibility and capability, whether material, physical, or causal (can equals is able to).

3. Definitions, acronyms, and abbreviations
3.1 Definitions
For the purposes of this document, the following terms and definitions apply. The IEEE Standards Didionaly Online should be consulted for terms not defined in this clause.
360-degree camera: A camera designed to capture 360-degree spherical surfaces.
4K ultra high definition (4K tJ LID): A term referring to high-definition resolution with a horizontal resolution in the order of 4000 pixels.
8K ultra high definition (8K U HD): A term referring to high-definition resolution with a horizontal resolution in the order of 8000 pixels.
accelerometer: A sensor for measuring linear acceleration or angular acceleration by measuring inertiainduced reaction.
angular resolution: A value of representing an interval between pixels of an image displayed by a head- mounted display (HMD) on the basis of an angle. The unit of measurement is pixel per degree (PPD).
background complexity: The number of figures, colors, and sizes of objects, and the level of optical flow in background scene. The background complexity may have an effect on cybersickness.
binocular disparity: Difference in image location of an object seen by left and right eye images.
biomarker: A biomarker, or biological marker, generally refers to a measurable indicator of some biological state or condition.
constant bit rate encoding (CBR encoding): An encoding method where the codec’s output data is consumed at a constant rate with respect to time.
chromatic aberration: An effect resulting from dispersion in which there is a failure of a lens to focus all colors to the same convergence point.
contrast ratio (CR): The ratio of the luminance of the brightest color (white) to that of the darkest color (black).
controllability: The level of control over virtual reality (VR) content, which can be either an active control experience or passive exposure to VR content. The more passive the VR experience is, the less controllability the user has.IEEE Std 3079 pdf download.
