Mediated communication between remote social spaces is a relatively new concept. One current example of this interaction is video conferencing among people within the same organization. Large-scale video conferencing walls have begun to appear in public or semi-public areas such as workplace lobbies and kitchens. These connections provide a link via audio and/or video to another space within the organization. When placed in these spaces, they are often designed for casual encounters among people within that community. Thus far, communicating via these systems has not met expectations. We are exploring a different approach to linking spaces through the use of what we are defining as a social catalyst. These catalysts are incorporated into our installation, Telemurals. An ethnography study of Telemurals will be conducted between two graduate dormitories to see how the catalysts affect interaction.
