A Line Animation Design Using Relative Changes in Non-Verbal Voice Information

Abstract

Individual creative design with personal computers has become common. However, at least in the animation design process, two problems remain: cumbersome setting tasks for design parameters and few environments in which users can simultaneously handle parameter setting and animation preview. We thus propose a novel interface for line animation design using relative changes in non-verbal voice information. In the interface, a user associates voice parameters (volume or pitch) and design parameters by uttering in time with an animation. Then, design parameters can be adjusted by uttering again in accordance with the relative change in voice. In a preliminary experiment, we confirmed that there are universal correspondences between the direction of change in design parameters and the direction of change in non-verbal voice. In addition, from users monitoring with the system, we verified the validity of non-verbal utterances and revealed the characteristics of voice input.
