Onderzoeksproject bachelor Informatiekunde, Cognitie en Communicatie Titel: Users’ mental models of hypertext systems Doel: Insight in the difference between users’ mental models and the conceptual model of hypertext systems during the design process Projectbeschrijving: Being disoriented or lost is one of the fundamental difficulties which users experience when trying to navigate a Website. If it has been designed so that it does not correspond with users’ mental models, then the users are more likely to become lost (Brandt. & Uden, 2003; Otter & Johnson, 2000). Consequently, evaluating and detecting users’ misunderstandings early in de design process saves a lot of problems in terms of satisfying user needs, defects, cost, etc. In this project we propose to explore the users’ mental models using the methodology of Otter & Johnson (2000). Participants are asked to draw (from memory) pathways through the system. The diagrams produced are easily analysed assuming they consist of a representation of nodes and links. The accuracy of the users’ mental models is measured by comparing them with the conceptual model of the hypertext system. Furthermore, this methodology allows exploring how mental models evolve while interacting with the system.
