2D Animation Authoring System with FTIR Multi-touch Table

Interactive Tokyo 2007

Kenshi Takayama, Takeo Igarashi



We demonstrate an intuitive animation authoring system where novice users can manipulate shapes of 2D characters directly with their fingers. The shape manipulation is achieved through the as-rigid-as-possible deformation algorithm proposed by Igarashi et al. [2005] and the input device is based on the FTIR (Frustrated Total Internal Reflection) multi-touch technique proposed by Han et al. [2005] which is very inexpensive and robust. With our system, even small children can create interesting and lively 2D animations easily and quickly, which would be difficult using traditional methods such as keyframing.
