Abstract

Following multimedia lectures in mainstream classrooms is challenging for deaf and hard-of-hearing (DHH) students, even when provided with accessibility services. Due to multiple visual sources of information (e.g. teacher, slides, interpreter), these students struggle to divide their attention among several simultaneous sources, which may result in missing important parts of the lecture; as a result, access to information is limited in comparison to their hearing peers, having a negative effect in their academic achievements. In this paper we propose a novel approach to improve classroom accessibility, which focuses on improving the delivery of multimedia lectures. We introduce SlidePacer, a tool that promotes coordination between instructors and sign language interpreters, creating a single instructional unit and synchronizing verbal and visual information sources. We conducted a user study with 60 participants on the effects of SlidePacer in terms of learning performance and gaze behaviors. Results show that SlidePacer is effective in providing increased access to multimedia information; however, we did not find significant improvements in learning performance. We finish by discussing our results and limitations of our user study, and suggest future research avenues that build on these insights.
