The group-in-a-box (GIB) layout is an efficient graph-drawing method designed to visualize the group structure of graphs. The layout communicates group sizes and both within-group and between-group network structures simultaneously. The layout is characterized by its composition of multiple elements, including nodes, edges, and boxes. However, there is limited empirical guidance on how these elements should be combined. In this paper, we measured participants’ task performance and eye movements while identifying the group with the largest number of inter...Ver más

In Japan, the percentage of traffic fatalities involving individuals aged 65 years and older is higher than that of other age groups. This issue can be addressed by having elderly individuals reflect upon their driving habits. Currently, this involves repeatedly attending training sessions at driving schools, which can be challenging due to time and location constraints. Hence, we develop a driving-review robot that allows elderly people to self-assess their driving skills in their homes. In developing this robot, we identified two crucial factors: “supp...Ver más
