This paper describes the application of Spatial Operational Sequence Diagrams (Spatial OSDs) to the analysis of usability, as it relates to the ‘walk-up-and use’ product category. Whilst many within the human factors community are, rightly, concerned with highly interactive computerbased systems, and apparently employ the very latest methods, we must not ignore the more traditional techniques such as Spatial OSDs. It is illustrated that Spatial OSDs can provide a most useful contribution to product usability evaluation and that the overall power of Spatial OSDs is greatly enhanced when considered in careful combination with other (task) analysis methods. The goal of this exploratory work is to provide insight into the cognitive aspects of the user-product interaction, where users can be regularly consulted on their actions and the relationships between them.
