How level and type of deafness affect user perception of multimedia video clips

Speaker: Dr Stephen Gulliver
Title: How level and type of deafness affect user perception of multimedia video clips
Abstract: This talk describes research which investigates the impact that hearing level and type has on the perception of multimedia. Independent variables include use of captions and deafness type. The Quality of Perception (QoP) metric was used to assess user perception and encompasses both the user's level of satisfaction, but also user ability to assimilate informational content. Experimental results show that hearing has a significant effect on participants' ability to assimilate information from multimedia, independent of video type or use of captions. It is also shown that captioned video does not necessarily provide deaf users with a greater level of information but changes user focus, providing a greater level of contextual narrative information.
