This standard provides requirements and recommendations for the design of non-keyboard input devices. It only includes devices for which there exist sufficient published ergonomic information. This standard applies to several types of non-keyboard input devices designed for stationary use. It gives guidance based on ergonomic factors for the following input devices: mice, pucks, joysticks, trackballs, tablets, overlays, touch sensitive screens, styli and light pens. It gives guidance on the design of these devices used for typical office tasks so that the limitations and capabilities of users are considered. This standard specifies methods for determining conformance through observation and by measuring the physical attributes of the various devices.
