ISO 9241-400:2006为交互式系统的物理输入设备提供了指南。它基于人体工程学因素为以下输入设备提供指导:键盘、鼠标、圆盘、操纵杆、轨迹球、轨迹板、平板电脑和覆盖物、触摸屏、样式、光笔、语音控制设备和手势控制设备。它定义并制定了适用于输入设备设计和使用的人体工程学原则。这些原则将用于生成产品设计和使用建议。它还定义了ISO 9241的整个400系列的相关术语。对于某些应用，e。 g、 在主要关注安全的领域，其他附加原则可能适用，并优先于此处给出的指南。 ISO 9241-400:2006还确定了与可用性相关的输入设备的特性，包括功能、电气、机械、可维护性和安全相关特性。此外，还包括与使用环境和软件的相互依赖性方面。

ISO 9241-400:2006 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. It 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. It also 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. ISO 9241-400:2006 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.
