Dourish (2001), Where the Action Is · Goffman (1963), Behavior in Public Places
Embodiment. Dourish defines embodied interaction as “the creation, manipulation, and sharing of meaning through engaged interaction with artifacts” — meaning arises in the dealings between people and things rather than being held in the system beforehand.
Co-presence. Goffman’s condition is stricter than sharing a room: people are co-present when they are “close enough to be perceived in whatever they are doing, including their experiencing of others, and close enough to be perceived in this sensing of being perceived”.
The two do not imply each other. Used here as the condition the rest of the framework sits on.
