Scope

This part of ISO 9241 gives guidelines for physical input devices for interactive systems. It provides guidance based on ergonomic factors for the following input devices: keyboards, mice, pucks, joysticks, trackballs, trackpads, tablets and overlays, touch sensitive screens, styli, light pens, voice controlled devices, and gesture controlled devices. This part of ISO 9241 defines and formulates ergonomic principles valid for the design and use of input devices. These principles are to be used to generate recommendations for the design of products and for their use. This part of ISO 9241 defines relevant terms for the entire 400 series of ISO 9241. For some applications, e.g. in areas where safety is the major concern, other additional principles may apply and take precedence over the guidance given here. This part of ISO 9241 also determines properties of input devices relevant for usability including functional, electrical, mechanical, maintainability and safety related properties. Additionally included are aspects of interdependency with the use environment and software. Any of these properties may be subject to other regulations or standards. These are considered following the example of electrical properties. In this case, this part of ISO 9241 considers the following properties. - Properties influenced by overriding considerations. EXAMPLE Properties related to electrical safety cannot be influenced by the designer. - Properties that could impair usability. EXAMPLE The thickness of the cabling for a mouse or the weight of batteries of a hand-held device need to be considered.
