BioFace-3D: Continuous 3D Facial Reconstruction and User Authentication Through Single Earpiece Biosensor
The Problem
Camera based facial expression analysis requires users to be confined to a particular location and face a camera, hindering their practicality when the user is in motion or in poor lighting conditions. Moreover, traditional VR authentication schemes are not only inconvenient but also vulnerable to potential side-channel attacks.
The Solution
Researchers at the University of Tennessee and University of Texas, Arlington, have designed a single earpiece biosensor that can continuously and reliably sense facial movement, track 2D facial landmarks, and render 3D facial animations without visual input. Additionally, the technology is also capable of capturing both behavioral aspects, such as facial gestures, and physiological traits for two-factor authentication. This technology accurately identifies 53 facial landmarks with minimal error.
It delivers seamless, continuous 3D facial rendering and convenient authentication, resulting in a captivating virtual reality experience. This technology can be used for improved VR/AR human computer interaction, user authentication, smart home, and disability equipment integration.
