Design of ID Marker that Extends Use-Cases of Paper-Based Response Analyzer

Abstract

Response analyzer systems with ID marker sheets enable teachers to gather data about students’ understanding levels quickly at a low cost. ID marker sheets held by students are captured by front cameras and recognized to identify answers as well as students. However, holding ID markers during classes is a burden for the students. It may disturb continuous learning activities of students. Therefore, we propose a stationary marker for extending use-cases of paper-based response analyzer systems. Before designing the stationary marker, we have adopted a novel marker recognition method that realizes robustness for occulusions. We have also modified the method to improve performance. After that, we have also analyzed the limitation of the marker recognition method through simulation for designing the stationary marker. A comparative experiment with a conventional hand-held sheet method was conducted. We confirmed that the proposed stationary marker method is easier to use than the conventional hand-held sheet method.
