With the increasing distribution of multi-touch capable devices multi-touch interaction becomes more and more ubi- quitous. Especially the interaction with complex data (e.g. medical or geographical data), which until today mostly rely on mice and keyboard input or intense instrumentation, can benefit from this development. Multi-touch interaction offers new ways to deal with 3D data allowing a high degree of freedom (DOF) without instrumenting the user. This paper evaluates indirect multi-touch 3D selection techniques that can be used to interact with stereoscopic data. In this paper two gestural multi-touch selection techniques are presented and investigated with respect to positions on a stereoscopic multi-touch display and special consideration of objects displayed with different parallaxes. In an experiment it was shown that position and parallax have a significant impact on the interaction.
