ABSTRACT
Since the rst days of wearable computers in the 1970s, research in the eld has largely been on how wearable systems can enhance a single user’s interaction with the world around them. In an early denition, Mann stated that a wearable computer was a computer that is Ephemeral, Eudaemonic, and Existential, or always on, part of the user, and under the user’s complete control (Mann 1997). In this case, Mann was focusing on the potential for wearable computers for enhancing personal imaging. Similar denitions of wearable computers (e.g., Rhodes 1997, Starner 1999) focused on the benet that wearables could provide to the individual user and mediate their interaction in the real world. For example, the Remembrance Agent
