Abstract:
In this paper, we developed a system that helps teachers to identify the erroneous operations of a student in computer literacy classes quickly. We considered two requirements for the system: (1) recording all operations, and (2) providing summarized information according to teacher's requests. For the first requirement, the system records screen image for all operations that are acquired by global hook events. For the second requirement, we proposed the multi-level image presentation method. First, all captured images are grouped hierarchically according to their contents. Then, teachers browse captured images by controlling the level of grouped images. Consequently, they reduce the number of images to be confirmed and find erroneous operations quickly. We confirmed the effectiveness of the proposed method through the experiment. Subjects try to find erroneous operations from more than 700 images. Subjects using the proposed method decreased the time for finding erroneous operations by 60%.
