Summary

This work provides insights at the communication differences based on the medium. Human communication uses more than one channel at the same time, and while the information sometimes overlaps (redundant information) most of the time it transmits different messages, about the content of the message, or the state of the person. This kind of insight is useful in order to understand, analyze and design conferencing systems. When communication channels are limited different effects can be expected. While the visual channel does not have a complex coding as the audio channel, it provides great amount of information. Some of the visual cues that we use are:

However, these different cues cannot be isolated and analyzed individually, as the are used in harmony. Human communication is basically a multi-channel communication.
