Measure Method on Reaction Time of Visual Attention Using a New-Style Mechatronic Measurement System

In this paper, a new measure method was suggested to examine the reaction time of visual attention of drivers using a new-style mechatronic visual attention measurement system. The system can control the peripheral environment illuminance and the present of stimulus at the start locations, and change the color of stimulus in terms of visual attention shift theory in three-dimensional (3D) space. The measurement system included the setting of observation location, stimuli location, moving speed, environment illuminance. The paper introduced the test method of visual function and the test procedures of the reaction time. The results demonstrated that this measurement system can be used to examine the reaction time and judgment response of drivers in three environmental illuminance conditions, and show that the response training for visual attention can improve the vision judgment ability of drivers.
