This thesis explores interaction paradigms for virtual 3D models on large displays. We explored three distant freehand interaction paradigms and for each paradigm we implemented a prototype system. Among these paradigms, it has been found that pointing by hand/eye with selection gesture is the ideal technique to interact with such interfaces. In the pointing technique we reduced the 3D interaction into 2D interaction to explore the 3D contents presented on the large displays. We propose a pinch gesture to select items effortlessly: a gesture of touching index finger with the thumb. Also we found a user-friendly way to present content meta-information of the virtual 3D models and its interactive units during interaction.
