Abstract
In this paper it is advocated that the feedback loop between students and lecturer could be improved by making use of Augmented Reality (AR) techniques. The bidirectional communication teacher-students is sometimes hampered by students’ fear of showing themselves up in front of their classmates. In order to overcome this problem a system is proposed whereby lecturers receive immediate and private feedback both individualised for each student as well as aggregated for the whole class. With that purpose the lecturer, who is equipped with a head mounted AR display, can visualize symbols that student select to represent their status in relation to the lecture content. In order to explore the possibilities of this approach an experience was conducted in a lecture on a university course. The results are encouraging and suggest that as this technology matures and less intrusive AR display models become available, it could provide effective support to communication and interaction during lectures.
