Is Dynamic Visual Search Performance Sensitivity to the Visual Fatigue and Comfort of LED TV? A Comparative Experiment of Eight LED TVs
A comparative experiment was conducted to make clear whether dynamic visual search performance is sensitivity to the visual comfort of LED TVs by testing dynamic visual search performance and visual fatigue of eight LED TVs. 16 ordinary man from 18 to 45 years old were paid to participate in the experiment. And all subjects were arranged to doing the dynamic visual search task when velocity was 5°/s. Each participant took the same dynamic visual search tasks on the eight LED TVs in the experiment. The search time and accuracy of each participant were recorded. The results shows that there is significant difference about the accuracy and dynamic visual search time in the course of 5°/s movement velocity between different LED TVs. And there is corresponding mode of comfort, satisfaction, the subjective fatigue feeling between different LED TVs. Those results revealed that dynamic visual search performance was sensitive to visual fatigue and comfort under the situation of 5°/s movement velocity. The obtained results could be a reference for evaluating the quality of LED TVs for a specific visual search task.
