The main reason for pursuing the research was that by discovering these specific quality factors engineers and scientists will be able to set the right priorities when they work on either improving or inventing a better quality of video-chat services. Even though, the complete study of human behavior is out of the scope of engineers and technologists, knowing the basic preferences of users towards the current digital communication media, such as video-chat services is significant.
