Acoustics of teleconferencing

Tangible Teleconferencing

This paper describes a teleconferencing application that uses real objects to interact with virtual on-screen content. A variety of tangible interaction techniques can be used to load, translate, rotate and scale shared virtual models. In addition, snapshots of real documents can be easily introduced into the system and enlarged using a tangible lens. We describe the teleconferencing interface ...

Multimedia Teleconferencing Control Gateway

Many current systems have computers supporting human-to-human interaction in realtime using multiple media. Such interaction can become complex, and multimedia teleconferencing control systems--or conferencing systems, for short--have been created to control the complexity and promote the development of applications. These systems provide media transport, transport resource management, and sess...

Teleconferencing in endoscopic surgery.

The traditional methods of information dissemination by publication in journals and the classical model of instruction by apprenticeship have not been able to keep pace with the rapid advances in the fields of therapeutic endoscopy and laparascopic surgery. The advances in communications technology have made it possible to transmit images of operative procedures over long distances. In recent y...

Desktop Teleconferencing for Broadband Networks1

This paper describes a desktop teleconferencing system running between UNIX workstations using TCP/IP and UDP/IP protocols on ethernet, 2-Mbit/s router-connected ethernets and Fastpac-connected ethernets (10-Mbit/s). Throughput and error statistics are presented for the networks along with a subjective assessment of audio and video quality, delay, jitter and the effects of these network artefac...
