Abstract
A system for manipulating a computer generated animation in real time that includes a head mount configured to inhibit relative movement between the head mount and head of a wearer is provided. The head mount is coupled to a computer that processes data generated by the head mount in real time. Data generated by the facial movements of a wearer of the head mount is processed in real time so that an object, such as a cartoon in a virtual reality program, has facial expressions analogous to the facial expressions of the wearer, as the wearer is performing. A plurality of cameras monitor different localized regions of the wearer's face for sensing movements in these regions to generate data indicating movement. The cameras are attached to the head mount with flexible arms for precise positioning of the cameras. The cameras monitor each of the mouth, chin and cheek, and an eyebrow and forehead regions of the wearer's face and one of the wearer's eyes. A portion of reflective material adhered to the wearer's face in each of the monitored regions enhances the camera's ability to generate data indicative of the changing facial expressions of the wearer. While the facial expressions of the…
