Over deze norm
This part of ISO 9241 applies to physical input devices for interactive systems. It provides guidance based on ergonomic factors for the following devices: keyboards, mice, pucks, joysticks, trackballs, trackpads, tablets and overlays, touch sensitive screens, styli, and light pens, voice controlled devices, gesture controlled devices. This part of ISO 9241 gives guidance on the design of these devices so that the capabilities and limitations of users are considered. The guidance includes generic design criteria for physical input devices as well as specific design criteria for each type of device. Requirements for the design of products are given either as a result of context-free considerations (e.g. "The contrast of key legends shall be greater than ") or need to be determined in consideration of the specified design criteria for the intended use. Design criteria for the intended use are generally subdivided in task oriented categories if applicable, e.g. the resolution of a pointing device is given in relation to four levels of Index of Difficulty (ID) for the Fitts Test. The required category for the resolution can be determined on the basis of the task characteristics, user population and context of use for the intended application. This standard does not specify the appropriate categories for devices since according to the concept of usability a product has no inherent usability. Selecting the category to which a certain property of a device belongs to is subject to the design of a product. The target users of this part of the standard are manufacturers of physical input devices including product designers and test organizations. The guidance given here is to be used to determine design characteristics of the device for the intended context of use (i.e., user population, task, software or environment etc.). The data generated by them for the description of the properties of their products can be used for selecting the adequate device for an actual context of use on the basis of the task primitives relevant for the task of the specific user population and for achieving the required level of efficiency and effectiveness for a given system.
