Deaf and Hard of Hearing students who use visual accommodations face difficulties in following multimedia lectures due to the delay in visual translation and dividing attention between simultaneous visuals. As a result, deaf students miss information. We address these difficulties with two approaches: visual cues and live replay in recorded lectures. Our analysis found that when deaf students view the lecture videos with cues, they show less delay in switching to the active visual information source and report high satisfaction with the cues. The students who liked the cues were more likely to demonstrate reduction in delay time associated with shifting visual attention. Similarly, when deaf students used gaze controlled replay with lecture videos, they miss less information and report high satisfaction with live replay.
