Abstract

In this paper, we investigate the impact of real-time video enhancement techniques on video Quality of Experience (QoE) for users with low vision. To this end, we present the results of a lab-based user study, in which participants with low vision utilize a web-based media player to configure individual video quality enhancement filters (e.g. increased contrast, strong edge enhancement and lowered brightness) depending on types of content. Additionally, for each test participant we measured the visual performance to describe how low vision impacts video QoE. Our results show, that individual video quality filters positively impact the experience of the quality dimensions detail, text and content. Furthermore, we discuss insights from qualitative feedback from participants regarding overall utility and User Experience (UX) aspects of real-time video enhancements.
