Abstract

The "Virtual Attack Point" approach for pedestrian navigation, based on a traditional navigation strategy, is introduced and its potential advantages are explored. A user study, using paper-prototyping in the field, is presented. Results of this study raise issues and suggest how this navigation concept might perform. There is discussion of the interaction, landmarks, methodology and implications. Based on this a set of heuristics are recommended for the placement of virtual attack points.
