Accurate behaviour and believability of computer generated images of human head

Preserving the integrity of realistic animated Computer Generated (CG) Humans is tantamount to ensuring audience perception and believability. However, projecting accurate behaviour in CG humans remains a potential problem. The effects of facial behaviour display (Facial Expression, Head Movement and Eye Movement) in terms of audience perception (Believability, Eeriness and Accurate Behaviour recognition) were tested utilising a CG animated human head. The results of the study show areas of significance were recorded in the effect of CG human facial behaviour in participants' perception in response to three dependant measures. The most significant, eeriness, was caused by a category of facial movement whilst the inclusion of that facial expression and head movement created most believability. The accuracy of identifying behaviour was also increased by the inclusion of Head Movement. However, no significant effect was found for eye movement.
