ProDive: Projecting and Interacting Underwater

This position paper discusses and motivates a design space as well as interaction paradigms for projection not on water but under water. Projection surfaces have evolved from fixed white boards to any physical item that we decide to change into displays. Water itself is now used as 2D or 3D projection screens [1, 4], " touch screens " [5] and even as interaction paradigms [6, 9]. We discuss here why underwater projection can and need to evolve and how existing interaction paradigms are being challenged underwater.
