halfface

Halfface is a term used to describe something that covers, represents, or affects only one half of the human face. It appears in several fields—art, theater, medical prosthetics, and some areas of digital imaging. Because it is not a standardized technical label, the precise meaning of halfface varies by discipline.

In maskmaking and performance, a halfface mask covers half of the face while leaving the other half visible. This design emphasizes asymmetry and is common in masquerade traditions and contemporary theatre. In some contexts, these masks are called half masks rather than halfface.

In medicine and dentistry, a half-face prosthesis (halfface prosthesis) refers to an appliance that restores facial appearance on one side after trauma, surgery, or congenital defects. Such devices are often silicone or acrylic and are fitted to blend with the intact side, with a removable design for care and maintenance.

In photography and computer vision, half-face concepts appear in portrait cropping, privacy filters, and augmented reality, where only one side of the face is captured or analyzed. Researchers study recognition, pose estimation, and occlusion handling with half-face data.
