Alerting Accidents with Ambiguity: A Tangible Tabletop Application for Safe and Independent Chemistry Experiments

摘要

We propose a tangible learning system that facilitates chemistry experiments in a safe and independent manner. The system displays messages that alert a student to avoid a possible accident based on the experimental context. Here, we introduce the way of information presentation with three-dimensional ambiguity: semantic, spatial and temporal. Also, a prototype tabletop application named A3 (A-CUBE) is presented, which extracts various contexts in a procedure of a chemistry experiment. Finally, we report on an evaluation experiment to measure its usability and to test the feasibility.
