Abstract

Embodiments of the invention provide virtual reality tools used to develop improved infection control solutions. The virtual reality tools may be applied to a variety of health care environments to develop improved infection control solutions, including improved training systems for modifying human behavior regarding hand washing (or other infection control behaviors), improved systems for evaluating the effectiveness of a proposed infection control solution, and for a producer/seller of anti-microbial products to demonstrate the superiority of one product over another or the superiority of one proposed solution over another.
