Abstract

Although software products are becoming increasingly accessible and assistive tools like screen readers becoming widely available, people with low vision still face insufficient support when it comes to consumption of digital video content. In this paper, we present an accessible desktop video player software, which allows visually impaired to adapt the presentation of digital videos according to their specific needs. For visual enhancement, we implemented a broad range of image manipulation techniques, like adaption of contrast, color manipulation (e.g. inverting, grey scale transformations) and edge detection algorithms for sharpness optimization. Based on the feedback from low vision users, we discuss how to implement enhancement filter configuration and how to consider several input modalities.
