Abstract
The reproduction of glare scenarios in driving simulators is restricted by the limitations of conventional projector and display technology. In existing solutions, light sources are usually added to the optical path by combining common simulator technology with, for example, grids based on light-emitting diodes (LED). In this article, we introduce a new way to simulate glare sources on a common driving simulator back-projection screen using an additional projector and an additional reflective screen. In a first attempt, a concept with retroreflective sheets is proposed, and the requirements and current limitations of this setup are shown. Further development of the concept leads to an attempt with holographic diffusers. With an experimental setup based on the second concept, we aim to assess its feasibility, evaluate current challenges, and outline future requirements. The results show that it is possible to simulate a static glare scenario with correct geometrical conditions and headlights with luminances of about 100 000 cd/m2. Current limitations are an unbalanced color efficiency, the size and cost of available diffusers, and the black-level values and in-picture contrast of the used projector that cause an outshining of the environmental simulation.
