23、de it possible to render highly realistic content on high-resolution colour displays. The developments include advanced 3D display technologies such as autostereoscopic displays. The new 3D displays extend the capabilities of applications by giving the user more-realistic-than-ever perception in var

24、ious application fields. This is valid not only in the field of leisure but also in the fields of business and education, and in medical applications. Nevertheless, 3D displays have display-specific characteristics originating from the basic principles of the image formation applied for the differen

25、t 3D display designs. Among negative characteristics are imperfections that affect the visual quality of the displayed content and the visual experience of the users. These imperfections can induce visual fatigue for the users, which is one of the image safety issues described in IWA 3:2005. Neverth

26、eless, it is important for the end user to be able to enjoy of the benefits of the 3D display without suffering any undesirable biomedical effects. It is therefore necessary that a standardized methodology be established which characterizes and validates technologies in order to ensure the visual qu

27、ality of the displays and the rendered content. The development of such a methodology has to be based on the human perception and performance in the context of stereoscopic viewing. The negative characteristics, by nature, originate from both 3D displays and 3D image content. In this part of ISO 924

28、1, however, attention is focussed only on 3D display, for simplicity of discussion and as a first step. In ISO 9241-303, performance objectives are described for virtual head-mounted displays (HMDs). This is closely related to autostereoscopic displays, but not directly applicable to them. Consideri

29、ng the growing use of autostereoscopic displays, and the need for a methodology for their characterization in order to reduce visual fatigue caused by them, this Technical Report presents basic principles for related technologies, as well as optical measurement methods required for the characterizat

30、ion of the current technologies and for a future International Standard on the subject. Since this Technical Report deals with display technologies that are in continual development, its content will be updated if and as necessary. It includes no content intended for regulatory use.

32、Ergonomics of human-system interaction Part 331: Optical characteristics of autostereoscopic displays 1 Scope This part of ISO 9241 establishes an ergonomic point of view for the optical properties of autostereoscopic displays (ASDs), with the aim of reducing visual fatigue caused by stereoscopic im

33、ages on those displays. It gives terminology, performance characteristics and optical measurement methods for ASDs. It is applicable to spatially interlaced autostereoscopic displays (two-view, multi-view and integral displays) of the transmissive and emissive types. These can be implemented by flat

34、-panel displays, projection displays, etc. 2 Terms and definitions For the purposes of this document, the following terms and definitions apply. 2.1 General terms 2.1.1 3D display display device or system including a special functionality for enabling depth perception 2.1.2 stereoscopic display 3D d

41、at present, it is not easy to make the optical reproduction perfect, integral displays are not necessarily free from such factors of undesirable biomedical effect as accommodation-vergence inconsistency (see 3.7, 4.1). 2.1.7 stereoscopic images set of images with parallax shown on a stereoscopic dis
