A multimedia self-service terminal with conferencing functions

We developed a new platform for personal computer based self-service terminals with multimedia conferencing functions in order to provide networked multimedia capability and face-to-face interface. The platform is based on extending our desktop conferencing system called ConverStation/2. It provides ITU-T H.320 motion video audio communication, and shared chalkboard function between a self-service terminal and an operator terminal. It also provides scanned image data transmission for browsing and co-editing of images between a customer and an operator. We clearly separate the platform with application modules, by providing a string command interface between them; we enhanced our conferencing features to meet the requirements of self-service applications. The major new features include: 1) asymmetric operation and user interface of a shared chalkboard; 2) dynamic line connection/disconnection control, and 3) dynamic media (video/audio/data) control on ISDN communication. With these conferencing functions, more complex services such as consultation can be provided through self-service terminals
