How do people use remote communication systems?
A cognitive account based on users' mental models
This paper proposes a cognitive model that describes how users of remote-communication systems adapt their knowledge
used for face-to-face communication in real space to that useful in the virtual space that remote-communication systems provide.
The model represents users' knowledge hierarchically and consists of Scripts, Goals, and Actions.
It assumes that, when conducting virtual communication, the users retrieve an appropriate Script,
which is then expanded by the other Scripts and Goals,
terminating with Actions that the users intend to carry out in virtual space.
The users then map the Actions in virtual space onto those in real space
using their experience and knowledge about remote systems in general.
We argue that neither of the Script-Goal-Action knowledge nor the set of mappings
are initially optimal to fully utilize the system's functionality,
but that they are learned while using the system.
We report some evidence that supports our claim using the "shake-hand" example
in the HyperMirror remote-communication system.
We conclude by suggesting
that the model is useful not only for evaluating existing remote-communication systems
but also for designing future systems in terms of ease of use from the viewpoint of knowledge
necessary to use the system's full functionality.
