In the last few years, the miniaturization of projectors has gained certain momentum. Today, projectors are available that can easily fit into the palm of a hand. Moreover, these devices are even being integrated into mobile phones. Mobile projectors allow users to project digital imagery into physical space virtually anywhere and anytime. The unique characteristics of small-scale projectors open up interesting opportunities for mobile user interface research. This article provides a comprehensive overview of research on mobile projected user interfaces according to three pertinent research directions: (i) nomadic, (ii) handheld, and (iii) tangible projection interfaces. Furthermore, the article outlines future research challenges and indicates trends in neighboring research fields that might foster innovation in the mobile projected user interfaces domain.
