Handiness of device-free response analyzer systems in the classroom

摘要

Response analyzer systems with AR markers help teachers to gather data about students’ understanding levels quickly and at a low cost. In such systems, marker sheets held by students are recognized by front cameras that identify answers given by students. However, holding AR markers during classes is burdensome. Therefore, we propose a stationary marker for response analyzer systems. To evaluate the stationary marker system, we compared the conventional way of holding markers sheets with the proposed stationary method. The results show that the proposed stationary marker method is easier to use than the conventional method of holding markers.
