Moving model of a CG head and its parametric expression of gender and age

We evaluate the extent to which gender and age can be expressed in the movement of a CG human head through subjective tests. We first introduce a model of CG head movement. Then, we change the model parameters and apply it to the CG heads of a child, an asexual robot, an adult male, an adult female, and an older male. From the statistical analyses of the subjective test results of the various head movement trajectories, we found that (1) we do not need to attend to the movement differences of gender and age but just the use of the face of each gender and age, and (2) there are possible movement parameter values that emphasize and de-emphasize the expression of gender and age, though they must be weak even if they surely exist.
