Widget Standardisation through Abstract Interaction Objects

Interaction Objects, Computer Systems, Presentation, Standardisation, System Development, User Interface Design, Visual Performance. Terminal recommendations and rules from most standards generally include references to various interaction objects belonging to different target environments. Since these references are not made explicit, the standard user is responsible to make a pattern matching between rules contents and physical interaction objects. To avoid problems that such a translation induces, a common view on standardised interaction objects is suggested through the use of abstract interaction objects. By this way, recommendations and rules can be expressed independently of target environments without relying on various particularisms. INTRODUCTION Since European directive 90/270/EEC articles (EEC, 1990) are relatively general (Abernethy, 1993), they are often linked to relevant parts of another standard related to human-computer interaction, i.e., ISO 9241 (ISO, 1992). Part 10 of this standard contains different recommendations on dialogue principles to be applied for assessing usable user interfaces (fig. 1). This part subsumes links to other part of the same standard which are related to different interaction styles (e.g., Presentation of Information in Part 12, User Guidance in Part 13, Menu Dialogue in Part 14, Direct Manipulation Dialogues in Part 16, Form Filling Dialogues in Part 17).
