Abstract

There are few previous empirical studies on an automatic speed control of multimedia materials based on a natural user interface (NUI) that distinguish note taking from watching to a lecture through nodding. This study conducted two experiments and an interview. First, in experiment 1, we found that there is significant relevancy between the participants' action of lowering their head and note taking. Second, we determined that nodding that lasts less than two seconds has no relationship to note taking. In experiment 2, we determined that the e-learning system with the automatic speed control of multimedia materials reported less learner manual control, clicking pause and rewind buttons, than the regular e-learning system. For the interview, the analysis shows that "The automatic speed control of multimedia materials" and "Note taking" influence "Participant's satisfaction" positively.
