Supporting group-to-group collaboration in videoconferences

Describes our experiences in an ongoing collaboration between our research group in Palo Alto and a similar group in Japan. The collaboration is based on semi-monthly videoconferences. Due to cultural and language barriers, we found it important to use a variety of communication techniques, ranging from audio and video to text-based chats. During the collaboration, we encountered a number of technical issues that caused communication breakdowns, and have taken various steps to improve the videoconferencing experience. In addition to improving the sound quality by using better microphone placements, we developed a number of systems that support different aspects of a videoconference. One of the new components is a system for panoramic two-way video communication that digitally combines images from an array of inexpensive video cameras. We also provided a means for the remote display of presentations, made design changes to our conference room and added support for taking meeting minutes and for reviewing captured videoconferences. These changes have resulted in an improved videoconferencing experience and in a more effective collaboration with our Japanese colleagues.
