What factors influence the quality of experience for WebRTC video calls?

Web real-time communication (WebRTC) based services introduce the new way of communication and collaboration. These types of services allow real-time communication with voice, video, messaging, and data sharing via browser. Their success and adoption depend on a number of different factors that influence user's experience and its quality. As WebRTC based services are growing, it is important to identify these influence factors (IFs) and investigate their impact on quality of experience (QoE). In this paper, the focus is on users' experience with WebRTC video calling. The objective is to determine the most and least influential factors in general according to examined users' opinions in the context of WebRTC video calling, and all for the successful management of QoE. With this in focus, this paper may serve as a basis for further research in the field in order to increase the utilization and adoption of WebRTC technology.
