    Simulation Fidelity Metrics for Virtual Environments Based on Memory Semantics

Session/Category Title:   Human Factors



    A photorealistic, computer-generated interactive environment strives to achieve the same sense of space as in the real world. Subjective measures based on human spatial perception supplementary to accurate geometry, illumination, and task performance, reveal the actual cognitive mechanisms in the perception of a virtual environment that are not otherwise apparent. In this sketch, we present a methodology for the assessment of simulation fidelity of virtual environments (VEs), centred on a validated theory of memory awareness states. It is challenging to identify whether VE simulations, displayed on head mounted displays (HMDs) and related interaction interfaces have an effect on the actual mental processes participants employ in order to achieve a spatial memory task in a VE, compared to reality and more traditional displays.
