CSA Preface
This is the first edition of CSA Standard CAN/CSA-ISO 9241-9, Ergonomic requirements for office work with visual display terminals (VDTs) - Part 9: Requirements for non-keyboard input devices, which is an adoption without modification of the identically titled ISO (International Organization for Standardization) Standard 9241-9:2000 (first edition, 2000-02-1 5). This ISO Standard was developed by the ISO Technical Committee ISO/TC 159 SC 4. It is part of the series of ISO 9241 Standards that address ergonomic requirements for office work with visual display terminals.
In conjunction with the adoption of this Standard, CSA is issuing a new edition of CSA Standard Z412, Guideline on Office Ergonomics. Basic principles and information from the ISO Standards have been used in the development of this CSA guideline.
Scope
This part of ISO 9241 provides requirements and recommendations for the design of non-keyboard input devices. It only includes devices for which there exists sufficient published ergonomic information.
This part of ISO 9241 applies to several types on non-keyboard input devices designed for stationary use. It provides guidance based on ergonomic factors for the following input devices: mice, pucks, joysticks, trackballs, tablets and 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 part of ISO 9241 specifies methods for determining conformance through observation, performance, and by measuring the physical attributes of the various devices.
