The development and application of a testing system of reaction time based on mesopic vision

The paper indicates a self-developed testing system of reaction time based on the theory of mesopic vision. The system is supposed to simulate the actual effects of tunnel lighting with varies of light sources, which could be attributed to mesopic visual environment. By adopting lights of different brightness, projecting designated graphs on the screen and capturing reaction time with a button, the effect of lighting condition to the human body can be obtained. The system equips with software, in which diverse projects can be created and also all the parameters and data can be put into a chart for later research. By providing theories and sequential experiments, the paper introduces hardware and software composition of the developed system. It is proved by facts that this system could throw light in the field of mesopic vision.
