ISO 9241-304:2008 provides guidance for assessing the visual ergonomics of display technologies with user performance test methods (as opposed to the optical test methods given in ISO 9241-305). Its use will help to ensure that, for a given context of use, a display meets minimum visual ergonomics requirements. It covers only visual attributes and does not address the ergonomics or usability of the whole product that houses a visual display.The main users of ISO 9241-304:2008 will be those who procure displays or who need to measure display performance during product development. Its application assumes a background in behavioural science.
