The Big Head project is […] a large, head-mount box with a 24″ LCD on the front showing a live video view of the wearer’s face. Of course, the face is flat, slightly miscolored, unmistakeably a video and much larger than usual.
The wearer’s face is captured with a video camera looking through a half-silvered mirror. There’s a second camera, which captures a view from the front of the box, near the eyes of the on-screen face. The outside view is shown on an internal LCD, which reflects on the half-silvered mirror; this way the wearer can look directly at the LCD and the camera at the same time. (This is essentially a tele-prompter, like Errorl Morris’ Interrotron).
The whole assembly is carried via floating frame, mounted to the shoulder and hips.
