Fatigue is factor which can cause health problems and decrease work efficiency. State of the art fatigue studies are mainly committed to investigating impacts of the Visual Display Terminal (VDT) screen luminance, resolution, and the distance between the VDT and operators. Fewer studies commit to understanding visual performance experienced by the operator when facing different conditions. This paper aims to find out whether the degree of fatigue and color combination of the interface that can influence visual performance when interacting with a text-based and eye tracking under exercise and no-exercise consideration. The viewing performance of 30 subjects was estimated by comparing eye tracker measurements before and after moderate exercise.

Visual reaction time is significantly affected by color backgrounds. Color background transfer results in a long reaction time, while the white background transfer leads to a short time reaction time. The testers who exercise before the experiment have more positive performance than those who do not in an attention test. For the subjects who exercised, the longer they were able to rest, the better their performance. Therefore, engaging in appropriate exercise may have a good effect on the performance of operators. Additionally, the change in interface motivates eye movements and improves eye performance.
