Create mandatory physical interactions with trigger objects…
Create mandatory physical interactions with trigger objects by placing them in the path of default behaviors rather than relying on passive visual cues.
Why This Is a Principle
This principle follows from affordances existing in agent-environment relationships (Action possibilities exist in the relationship between…) and physical proximity determining interaction likelihood (Physical proximity and visibility of objects…). It prescribes physical obstruction as a trigger design strategy because it converts a passive cue into an active interaction demand. Actionable and general across physical environments.
