3 Terms and definitions
For the purposes of this document, the terms and definitions given in EN ISO 12100-1:2003 and the following
apply.
3.1

3.6
coding
procedure within the design process by which categories of information (e.g. form, colour, etc.) are allocated
to elements for the purpose of reliable identification
3.7
arrangement
way of combining or separating displays and control actuators relative to their function, task and/or location
3.8
surface
surface on which elements are positioned and arranged, considering task priorities, information flows, and
space constraints
4 Principles for location and arrangement of displays and control actuators
The location and arrangement of displays and control actuators are intended to ensure the general reliability,
safety and efficiency of the human-machine system. The most important tasks of the operator are to monitor,
control and ensure continuous availability of the technical system and the interaction of its elements. This shall
place the operator in a position to fulfil the following functions correctly and on time without becoming
overtaxed:
 to perceive the current tasks;
 to control the operation;
 to select and/or develop suitable action strategies.
Basic principles for human machine interaction are given in EN 894-1.
The following describes a design procedure that will assist designers and manufacturers in complying with the
requirements in this standard. It consists of six main phases, each of which contains several more detailed
steps. These steps should be carried out iteratively until the requirements are met. The procedure is illustrated
in Figure 1. In Phase 0 the initial information about the overall purpose, design goals and roles of the
operators (see EN 894-1) is assembled.
