An alternative view of presence is introduced based on existential philosophy and ecological psychology. This view favors a Heideggerian/Gibsonian metaphysic over the more conventional rationalistic orientation. In this alternative view, notions of subjective presence and objective presence no longer exist. Presence is instead tied to one's successfully supported action in the environment, this environment being either virtual or real. The coupling between perception and action is crucial for determining the extent to which actions are successfully supported. It is argued that this alternative view provides needed guidance and simplification for the evaluation of presence.
