From tasks to conceptual structures: misfit analysis
ANN E. BLANDFORD, T. Green · 2001
Ontological Sketch Modelling (OSM) is an approach to usability evaluation that focuses on structures rather than tasks, and assesses the goodness of fit between the user’s conceptualisation of a system and that actually implemented by the designer. It provides a common representation that supports reasoning about users, domains and devices. In this paper, we introduce the rationale behind OSM, the approach itself, and a short case study of applying it to an electronic diary system.
