Research on the Visual Search Ability Decline Caused by Different Types of Noise

With the arrival of Industry 5.0, human factors are gradually receiving more widespread attention. To research the visual search ability decline caused by different types of noise, we collected three common types of noise in factories. 30 participants have been invited to complete visual search tasks in different noise level conditions. The participants have been divided into the noise sensitive group and the noise insensitive group. By analyzing the task complete time, reaction time, average pupil diameters during the task, and visual hotspots during the task. It has been verified from two dimensions: work efficiency and physiological changes that factory noise has a negative impact on visual search task. Compared to single continuous noise processing, the composite noise has more significant impact on visual search tasks. Especially for noise sensitive individuals, random noise has more significant impact on visual search compared to regular noise.
