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

A-CUBE: A Tangible Tabletop Application to Support Safe and Independent Chemistry Experiments

“…At the same time, Figure 2 Examples of information presentation: When an operator puts a mortar on a table (left), the system presents information with ambiguity; Sem: L, Spa: L and Tem: L. In heating a test tube (right), with ambiguity; Sem: H, Spa: L, Tem: L. Note that Sem, Spa, and Tem indicate Semantic, Spatial, and Temporal ambiguities, respectively. The definitions can be found in [7]. Figure 3 Definition of marker-centered coordinate system (left) and the positional adjustment of presentation (right) to avoid being projected out of a table.…”

“…The potential of multiple interpretations as a mean to facilitate reflection and increase awareness of related topics has been considered in other studies [3,6]. For more detail of the three types of ambiguity, please refer to [7].…”

Spatial connectedness of information presentation for safety training in chemistry experiments

“…We have proposed a tangible chemistry experiment support system that helps safety training for the beginner in order to avoid danger [2]. For designing the system, it is important to keep the balance between learning safety experiments and being safe at the experiments.…”
