Abstract
The introduction of standards will hopefully ensure that users can access particular computer resources through a communications network for their own purposes without major problems. The International Standards Organisation (ISO) has developed a seven-layer reference model which is to be used for the purpose of incorporating standards relating to the interconnection of open systems (OSI). It is important that the human factors requirements are considered in relation to this model if the aim of generality of use is to be achieved. This paper considers some of the major human factors requirements and describes an approach to translating them into design standards which can be implemented. The approach starts from a consideration of user activity and develops into a language interface which could reside in layers of the reference model.
