| Research Abstract |
Previous researches reported that, in general distance education environments, novice instructors tend to fail to perform effective educational interventions to distant learners due to deterioration of the quantity and the quality of communication information. This inadequate educational interaction further results in low learners’ satisfaction and poor learning outcomes. The authors addressed this issue by developing a new synchronous distance education system. The system was designed to provide instructors with enough learner’s status information, to ensure better educational communications between instructors and learners at the far end.The system consists of two subsystems, i.e. (i) learner’s internal state estimation (LISE) algorithm and (ii) AR enhanced learner’s state visualization (LSV) system. LISE algorithm estimates learner’s learning status based on time series trajectory of their head positions. Evaluation test revealed that LISE algorithm holds satisfactory accuracy in status estimation and that LSV system supports instructors to perceive learner’s status more easily than ever, with the help of AR.As a conclusion, this study demonstrated that visualizing learner’s status with AR facilitates the perception of learner’s status by instructors in synchronous distance education environment and promotes effective interventions to distant learners.
