In this paper we present some results obtained through an experimental evaluation of tangible user interfaces (TUIs), comparing their novel interaction paradigms with more conventional interfaces, such as a joypad and a keyboard. Our main goal is to make a formal assessment of TUIs in robotics through a rigorous and extensive experimental evaluation. Firstly, we identified the main benefits of TUIs for robot teleoperation in a urban search and rescue task. Secondly, we provide an evaluation framework to allow for an effective comparison of tangible interfaces with other input devices.
