Browsing methods for multiple online handwritten note animations

We proposed a student note-sharing system to facilitate collaborative and interactive learning in conventional classrooms. Student notes can already be immediately shared by the students and teacher, using a projection screen. However, the resolution is currently insufficient to allow each student note to be shown in detail, which lessens the learning benefits. To address this issue, we proposed two browsing methods that allow simultaneous viewing of multiple online handwritten note animations. In both methods, the zoom rates were determined automatically. Experiments were conducted on the readability of texts, the visibility of figures, and the intuitiveness of animations. The results demonstrated that the animations produced by the ConstantZoom method were more intuitive than those produced by the VariableZoom method.
