We describe a pilot study of the use of a mixed reality environment for distributed presentations involving virtual and physical audiences and speakers. Our aims were to establish mutual awareness between all participants; to present physical and virtual worlds as being spatially integrated; and to support moderate sized audiences. We used a mixed reality boundary to join a physical space to a collaborative virtual environment so that the two appeared to be adjacent but distinct components of a single space. Two presentations were staged to a mixed physical and virtual audience, one by a virtual speaker and one by a physical speaker. Each presentation was followed by a question and answer session. Qualitative analysis of semi-structured interviews and video recordings revealed that some degree of mutual awareness was established between participants and that physical participants may have viewed the environment as being more spatially integrated than virtual participants. We propose that improving avatars and video textures in the virtual environment may further enhance the experience.
