Evaluation of Content Handling Methods for Tabletop Interface

We focused on face-to-face collaborative learning in a classroom using spatio-temporal contents, which is typically conducted after outdoor class in an elementary school. We have developed a tangible collaborative learning support system that uses physical objects and associating spatio-temporal contents. We have implemented a few methods to handle these contents. Two experiments were conducted to confirm that better information accessibility was provided by the system than conventional pen and paper method.
