This paper describes preliminary results of research on the perception and usability of interfaces projected onto realworld objects. Using a projector setup that enables us to compare users' color preferences, we show that the objects onto which colors are projected influence a user's choices. We also observe that many users are unable to recall and/or were unaware of the objects onto which the color interface was projected. These results suggest that there may be complex interactions affecting the use of interfaces that integrate the virtual and the real world. Keywords Augmented reality, projected interfaces, tangible interfaces, functional fixedness.
