About

Andrei State is a pioneering researcher in augmented reality (AR), medical visualization, and human-computer interaction. His most influential work centers on the development of "Animatronic Shader Lamps Avatars," a groundbreaking technique that uses projected light to animate physical, three-dimensional human faces in real time. This innovation, detailed in his 2009 and 2010 papers (garnering 53 and 24 citations respectively), addresses the critical challenge of conveying non-verbal cues—such as head pose, gaze direction, and facial expression—in telepresence and training applications. By combining physical avatar models with dynamic, computer-controlled shading, State’s research enables more natural and compelling human representation than conventional displays allow. His contributions have significantly advanced the realism of remote communication and collaborative environments. With a career spanning decades at the University of North Carolina at Chapel Hill, State has also made foundational contributions to medical AR, including early work on ultrasound-guided procedures. His research continues to shape how we blend digital and physical realities, making virtual humans more believable and effective for education, healthcare, and beyond.
