Ergonomics of human-system interaction - User performance test methods for electronic visual displays Ingestion-build-44680 BS EN 1021‑1 and BS

BS EN 1021‑1 and BS 5651 provide suitable methods of cleansing or wetting

Selectivity is the ability of the receiver to discriminate between wanted and unwanted input signals

The main aim of the BS 4857 series is to provide manufacturers with best industry testing methods to determine the performance of terminal reheat units

Ergonomics of human-system interaction - User performance test methods for electronic visual displays Ingestion-build-44680 BS EN 1021‑1 and BS1 Scope This part of ISO 9241 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
