Abstract

Camera-based response analysers are classroom enhancement tools like clicker tools that teachers can use to collect students' answers. A camera-based response analyser can reduce the cost of such student devices because it recognises AR marker sheets to collect students' responses. However, conventional camera-based response analysers are sensitive to occlusion. In addition, holding markers while capturing is troublesome. To mitigate these issues, we have developed a response analyser system that employs recognition of random dot (RD) and stationary markers. We have improved the performance of the system to recognise the RD markers using a typical background colour. We confirmed the basic performance of the modified response analyser system and the proposed stationary markers experimentally.
