Based on the fact, an interactive 3D animation system for
tablet devices have been developed [1]. With the system, different
3D animations are played depending on a view direction
to the 3D object and user’s gesture input. However, the
system has two critical issues to be more commonly used.
The first one is the complicated process for data creation, and
the other is a conflict on gesture recognition that comes from
an ambiguity on retrieving 3D information from 2D input. In
this paper, solutions for those two issues are proposed.
