Study of the Stroboscopic Effect Visibility Measure(SVM)based on Cognitive Performance
There have been many studies on stroboscopic effect from LEDs,which is considered unacceptable to affect psychological cognition.As a new measurement,Stroboscopic Effect Visibility Measure(SVM),can quantify the visibility of stroboscopic effect in general lighting applications.However,the relationship,if any,between SVM and human cognitive performance has not been specifically elucidated,such as spatial environment and work performance.Therefore,under six SVM values representing different lighting environments,through the D2 task,the rotating disk and the Landolt ring task,objects can perceive the stroboscopic effect in lighting environment,and use scales to make the self-cognitive judgement of spatial environment and work performance.The experimental results show that there is a significant relationship between the visibility of stroboscopic effect and cognitive performance.Subjects reported flicker,discrete spatial motion and bad environment perception in response to the higher visibility of stroboscopic effect.In addition,the visibility of stroboscopic effect also may have a significant impact on physiological indicators,subjects are more nervous during the D2 task,meanwhile the vision and attention are all decreased with a high SVM during the rotating disk.
