Videodescription (VD) or audio description is added to the sound track of audio-visual contents to make media such as film and television accessible to individuals with visual impairment. VD translates the relevant visual information into auditory information. In our previous users' testing, we found that the need of VD could be quite different depending on the visual disabilities of the participants. In order to better identify those differences, we conducted a study with ten legally blind individuals (with and without residual vision) to observe the type, quantity and frequency of the information needed by them. We learned that the degree of residual vision and the complexity of the content have a significant impact of the required level of VD. This suggests that a tool to render VD should offer a basic level of information, allow enough flexibility to provide more VD if needed, and answer on the fly demands for specific information. These specifications were implanted into an accessible video player.
