In this study, we investigated the way users memorize, analyze, collaborate, and learn new concepts on a Tangible User Interface (TUI). Twenty-seven pairs of apprentices in logistics ( N = 54) interacted with an interactive simulation warehouse. Their task was to discover efficient design principles for building storehouses. between-subjects experimental design, half participants used 3D physical shelves, whereas other 2D paper shelves. This manipulation allowed us control “representational effect” tangibles: first group saw warehouse as small-scale model realistic second had access more abstract layout rectangular pieces paper. Both groups system same way. We found that (i.e., who shelves) better memorized layout, built model, scored higher learning test. Additionally, students wore eye-tracking goggles while completing those tasks; preliminary results suggest interfaces increased joint visual attention, which be significant predictor participants’ performance gains. Implications designing TUIs collaborative settings are discussed.
