We describe interaction techniques for browsing 3D media using our cylindrical multi-touch interface (CMTI). CMTI uses a cylinder wall as its controlling surface. Because the control area of the interface is in cylindrical polar coordinates, the use of the depth along the surface enables the user to interact in 3D space even though the controlling surface is still a 2D surface. Moreover, the nature of the multi-touch interface enables the user to manipulate objects and the viewpoint with both bare hands. The user can easily examine complex 3D media using the interaction techniques described with the power of CMTI.
