A 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: 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 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.
