Application of A Measuring System for Visual Judgment Ability of Drivers in Real Three-dimension Space

This paper introduces the application method of a measuring system for visual judgment ability of drivers in real three-dimension space (3D) based on the visual attention theory. The measuring system can simulate the traffic environment and driving conditions, and is made up of five parts, signal display system, data recording system, traffic environment simulation system, experimental seat and computer control system. It can control the peripheral environment illuminance and the appearance of stimulus at the target locations, and change the colour of stimulus. The paper demonstrated that the measuring system can be used to examine the reaction time and judgment response of drivers in real three-dimension space during driving, and show that the response ability training for visual attention of drivers can improve the vision judgment ability.
