Enhancing video communication experience for low vision users

Published: 20 May 2021 Publication History

Abstract

In this paper, we investigate the impact of various video enhancement techniques on the video chat user experience of people diagnosed with low vision. To this end, we present the results of an exploratory user study, in which participants with low vision were asked to utilize an accessibility-enhanced video chat client to perform two tasks (interviewing and facial emotion recognition). Participants were able to individually configure the appearance of the video by defining several media enhancement parameters (e.g. contrast adaption, edge detection and enhancement, gray scale modes, etc.) to compensate for their own individual visual impairments. Our results show that individual video enhancement configurations positively impacted the video chat experience of the interview task. Also the second task benefited from the video enhancement, i.e., more facial emotions were correctly identified.
