Research on Mechatronic System of Comprehension Reaction Time in Mesopic Vision

Abstract

The paper presents a mechatronic system designed to simulate the surroundings of night-driving roads in mesopic vision. Visual Performance in the mesopic range to define mesopic visual performance is thought of the most essential methods to research the mesopic vision. And there is no standard model to evaluate the mesopic performance. Therefore, the experimental system BJ-MV2 is designed to measure and record the reaction time. By changing the parameters of mesopic environment, we get a series of experimental data and calculate curve-fitting data. According to the curve, the tendency of reaction time appears clearly and BJ-MV2 is proved to be a reliable system for researching mesopic vision.

Dynamic Visual Performance of LED with Different Color Temperature

“…However, these didn't accurately reflect the dynamic changing process of the target, when drivers close to the target with a certain speed. Therefore, in order to research the dynamic visual performance of LED in mesopic vision conditions, A dynamic visual performance test system has been developed and built in the previous related research [18][19]. When dynamic visual targets were chosen, and three different color temperature LEDs were selected as background light sources, and the testing system was used to collect reaction time of testers.…”
