A study on the effect of different channel cues on learning in immersive 360° videos.

Immersive 360° videos are of interest to educators because of their ability to provide immersive sensory experience and other features. This study examined the effects of four cue conditions on 360° video learning performance, attention, cognitive load, and mood using eye-tracking devices, brainwave meters, and subjective questionnaires. The randomly assigned participants ( n = 62) did go to the experimental group (visual cues only, auditory cues only, and audiovisual cues) or the control group (no cues). The results showed that visual and audiovisual cues effectively guide learners' attention to the related learning content, reduce cognitive load during learning, and improve retention performance but have no significant effect on knowledge transfer or long-term memory. Auditory cues increase the number of times learners look at the related learning content but do not affect gaze duration and distract their attention, hindering the acquisition of relevant learning content. The study also found that visual cues effectively increase the number of times learners looked at the content. However, they do not affect gaze duration. The study also revealed that visual cues effectively increase learners' relaxation when viewing 360° videos. The study's findings can provide a reference for the instructional processing of information related to 360° video design and its practical application in teaching.
