Development of Peripheral Feedback to Support Lectures
- 1.5k Downloads
In this paper we describe a service that provides peripheral feedback on participation level of the audience in lectures and seminars to presenters. The peripheral display makes the lecturer aware of the attention level as well as the interest level of their students. We hypothesise that providing this kind of feedback can help lecturers or presenters to adjust their behaviour to the cognitive demands of the audience. In this paper we report on the results obtained from a focus group and two surveys that were carried out. Following that we describe the development of peripheral displays focusing on the design considerations and process of the teacher support service. We describe the service by addressing its technological components and visualisations. Finally we briefly discuss the issues to be considered for the evaluation of such an unobtrusive service.
