Scope

This document provides guidelines for evaluating the visual ergonomics of display technologies using user performance testing methods, which differ from the optical testing methods in ISO 9241-305. This document helps ensure that displays meet the minimum requirements for visual ergonomics in given usage scenarios. This document only addresses the visual attributes of visual displays, not the ergonomics or usability of the entire visual display product. The general principles of this document apply to all color or monochrome visual displays in human-interactive systems. Displays include, but are not limited to, visual displays used in desktop and portable computers, mobile devices such as mobile phones, digital cameras, and personal digital assistants, as well as status displays used in consumer electronics devices such as printers, in-car navigation systems, and microwave ovens. This document expands on the basic concepts of visual performance and comfort testing, evaluating the quality of displays based on end users' own performance and judgments, which includes a more diverse range of technologies, users, tasks, and environments. Due to its diverse nature, this document does not provide a single, universal testing method applicable to all display technologies, but rather provides basic principles for developing testing methods. The developed methods can be used to evaluate specific displays in given usage scenarios, but the methods in Chapter 8 are only applicable to tasks in text processing scenarios. This document does not provide other examples. The basic feature of the testing method development process is allowing the performance and judgments of typical users to be used as measured quality data to verify the usability of visual displays in typical tasks. However, this method cannot measure special perceptual attributes such as brightness contrast or display flickering in closed states. The main users of this document are individuals who purchase displays or
