The Impact of Information Presentation Modes on Visual Search under Different Task Modalities

In recent years, the effect of information presentation on visual exploration in industrial system application software has received much attention, but there is less research on the effect of information presentation on visual exploration in the context of different task modes. In this paper, the industrial operation tasks are classified into three modes: one is the unconscious viewing task, the second is the daily operation task, and the third is the emergency operation task; and the information presentation modes are classified into three categories: one is text only, the second is picture only, and the third is the combination of picture and text, so as to explore the impacts of the different information presentation modes on the performance under the three kinds of task intensities. At the same time, a platform was built for different tasks to simulate the real operating environment, and the behaviour was quantified by collecting the subjects' task completion time and correctness rate, etc. The experimental data showed that the combination of graphics and text in Tasks 1 and 2 was the best information presentation method. The lower the information complexity in task one, the smaller the gap between the three presentation methods, the higher the information complexity, the lower the correct rate of the pure picture presentation method; in task two, the higher the number of information, the heavier the processing load of the pure text display method. In Task 3, which requires users to react quickly, the combination of graphic and text increases the amount of information, and the display of too much information reduces the operation efficiency, and thus is not the best presentation method.
