Research in Human Factors 8. Research in Human Factors Current research in the area of lighting simulation includes continual verification and enhancement of the GRAF-simulated camera images for each of the types of payload bay and onboard cameras used in both the Shuttle and ISS programs. In addition, studies are being done to determine the amount of value added to training with computer images that have been augmented with lighting effects. The concept of computer aided engineering as applied to the complex area of human modeling and human-machine interface necessitates that continuous research be done in order to enhance the GRAF's human models.
Research is also under way to improve the interaction between a user and a virtual environment.
Future implementations to the HVES may include the incorporation of the GRAF lighting model features in order to enhance the immersive quality.
