User Profile Analysis for Enhancing QoE of 360 Panoramic Video in Virtual Reality Environment

With the development and popularity of virtual reality (VR) and 360 panoramic videos with head mounted display (HMD), user satisfaction is very significant as compared to other important end to end quality of service. To improve Quality of Experience (QoE) of 360 panoramic video, user profile needs to be analyzed. The user profile analysis can provide vital information to service providers which can help them to deal with their resources capably, by evaluating users behaviour and expectation. In this paper, we conduct a subjective test and propose a method to investigate QoE in VR by analyzing user profile. To do this, we first store the user profile data (e.g. age, gender, familiarity with 360 panoramic VR video, interest in the content) then we investigate the impact of different factors that influence QoE (encoding parameters, content type and device type) on user. The results of our analytical study provide another opportunity for content providers to offer best level service that meets customers expectations and desired experience to obtain high user satisfaction. To the best of our knowledge, this is the first attempt that analyzes the user profile for 360 panoramic videos in VR environment.
