The Subtle Approach: Proxemic Interactions with Gradual Engagement and F-Formations
Proxemic Interactions describe how people’s interaction with their devices in a ubicomp ecology can be mediated by sensed factors such as distance and orientation. Yet there are subtleties that are not captured by proxemics alone. Gradual engagement is a design pattern that identifies the flow of interaction as entities approach. F-Formations is a social theory that can be used to both create federations of people arranged in a recognized spatial pattern, and enable particular interaction techniques between devices that exploit those spatial relationships.
