forthcomming 2005, Journal of Visual Languages and Computing (JVLC), prefinal draft, pls quote original 2 Abstract. The emergent interest in ontological and conceptual approaches to modeling route information results from new information technologies as well as from a multidisciplinary interest in spatial cognition. Linguistics investigates verbal route(More)
Successful wayfinding requires accurate encoding of two types of information: landmarks and the spatial relations between them (e.g. landmark X is left/north of Y). Although both types of information are crucial to wayfinding, behavioral and neurological evidence suggest that they have different substrates. In this paper, we consider the nature of the(More)
In producing diagrams for a variety of contexts, people use a small set of schematic figures to convey certain context specific concepts, where the forms themselves suggest meanings. These same schematic figures are interpreted appropriately in context. Three examples will support these conclusions: lines, crosses, and blobs in sketch maps; bars and lines(More)
Although considerations of discourse coherence and cognitive processing suggest that communicators should adopt consistent perspectives when describing spatial scenes, in many cases they switch perspectives. Ongoing research examining cognitive costs indicates that these are small and exacted in establishing a mental model of a scene but not in retrieving(More)
It is said, though not without controversy, that what distinguishes design from art is function. Design is for a purpose, usually a human one. As such, design entails both generating ideas and adapting those ideas to intended uses. This occurs iteratively. Form and function. Studying how people go about both these tasks gives insights that can facilitate(More)
This contribution reports on ongoing collaborative Extending the research on the effects of static vs. dynamic route presentation on perception and memory (Klippel et al., 2002), we examined different route presentation methods that are commonly used today (e.g. internet maps, GPS maps, etc.) and their effects on the subsequent route memory. Participants(More)
Motion can be an effective tool to focus user's attention and to support the parsing of complex information in graphical user interfaces. Despite the ubiquitous use of motion in animated displays, its effectiveness has been marginal at best. The ineffectiveness of many animated displays may be due to a mismatch between the attributes of motion and the(More)
