This article presents a comparison of the effects of input-output location (co-located versus discrete) on user performance in a tangible user interface (TUI) system. We conducted a mobile eye-tracking study with two different versions of a TUI system and, despite similar performances in both conditions, our findings revealed differences in the users’ gaze patterns, shedding new light on the underlying cognitive processes.
