Supporting individual situation awareness in Web-environments

چکیده
Samenvatting Gebaseerd op “Web-technologie” is een nieuw gebruikersinterface-paradigma ontwikkeld: de “Network User Interface” (NUI). Dit paradigma biedt nieuwe mogelijkheden voor de interactie met diensten voor informatie en commercie, maar brengt ook nieuwe problemen met zich mee zoals desoriëntatie en moeizame navigatie. De veronderstelling is dat een deel van deze problemen veroorzaakt wordt door beperkingen in de “situation awareness” (SA). Gebaseerd op ergonomische ontwerpprincipes en scenariospecificaties zijn drie ondersteunende functies voor een NUI ontwikkeld: “categorising landmarks”, een “history map” en een “navigation assistant”. Terwijl de eerste functie een meer klassieke manier is om de SA van gebruikers in het algemeen te ondersteunen, omvatten de andere twee nieuwe concepten voor het ondersteunen van de individuele SA. De ondersteunende functies worden momenteel geëvalueerd om vast te stellen in hoeverre ze de gebruiksvriendlijkheid verhogen en om hieruit ontwerprichtlijnen af te leiden voor navigatieondersteuning.
