Motion stroke-a tablet-based interface for motion design tool using drawing

Abstract

Conventional animation tools provide users with complicated operations which require them to adjust too much variables to design a virtual model's 3D motion. In the proposed system, "Motion Stroke", users can control these variables only by their 2D drawings on a tablet surface. The proposed interface allows users to create new motions through a trial-and-error process which is nature in drawing of a picture on a paper. It offers a familiar form for designing of a virtual object's motion. We conducted several evaluations and confirmed that the proposed system allows users to explore their desired motions flexibly. © 2009 Springer Berlin Heidelberg.
