This document summarizes a study comparing tangible user interfaces (TUIs) and gesture interfaces for human-robot interaction. The study tested navigation and posture tasks using either a Wiimote/Nunchuk TUI or a keypad interface with 20 participants. For both tasks, participants completed the tasks faster and with fewer errors using the Wiimote/Nunchuk TUI. Participants also overall preferred the Wiimote/Nunchuk technique. The results suggest that TUIs may be better than traditional interfaces for some human-robot interaction tasks.
