A high fidelity Virtual Human Interface (VHI) system was developed using low-cost
and portable computers. The system features real-time photo-realistic digital replicas
of multiple individuals capable of talking, acting and showing emotions and over 60
different facial expressions. These virtual patients appear in a high-performance
virtual reality environment featuring full panoramic backgrounds, animated 3D objects,
behavior and AI models, a complete vision system for supporting interaction and advanced
animation interfaces. The VHI takes advantage of the latest advances in computer graphics.
As such, it allows medical researchers and practitioners to create real-time responsive
virtual humans for their experiments using computer systems priced under $2000.
