Color Scheme Compensatory Evaluation Method Based on Eye Movement Tracking Technology

Abstract

In the process of product color scheme evaluation, subjective evaluation is liable to mislead evaluation and decision-making. To conduct a more objective quantitative evaluation for color schemes, a compensatory evaluation method for color scheme based on eye movement tracking technology is proposed in this paper. In this method, four types of eye movement experimental data-fixation time, number of fixation points, number of fixation times, and first fixation time-are collected in the area of interest (AOI) from the experimental sample by eye movement tracking technology. SPSS software is employed to test the reliability of the experimental data, and the value assignment method is used to perform compensation processing on the experimental data, so that the final evaluation result can be obtained with the assignment calculation. Taking the evaluation of the disguise color scheme of a camouflage uniform as an example, the operation process of the method is demonstrated, and the effectiveness of the method is verified with the questionnaire. The results show that the color scheme compensatory evaluation method based on eye movement tracking technology can achieve an effective evaluation of color schemes. This method realizes the quantification of and data compensation for color scheme evaluation, making the evaluation results more scientific and accurate and providing a reference basis for color scheme designers in evaluation and decision-making.

An eye- tracking technology and MLP-based color matching design method

“…Some real images such as natural landscape images, animal images and product images may exhibit a higher level of complexity, which can cause problems for conventional colour extraction. In fact, eye-tracking techniques are less disturbed by factors such as complexity 30 . Although increasing the number of image colours reduces the efficiency of visual search, it does not affect the results of colour extraction by eye-tracking techniques 31 .…”

“…The eye-tracking device used in this study was the Tobii Pro Glasses 2, manufactured in Sweden. The eye-tracking technique has less interferes with the acquisition of the subject's evaluation process and meanwhile enables the recording of various data during eye movements 30 .…”

“…The hot zone map method is selected for color extraction of animated images. The eye-tracking data visualization method should be reasonably determined according to the actual design evaluation content 30 , 31 , 40 – 42 . In the heat zone map method, the denser the hot spots, the longer the subject's gaze time in the area of interest, the longer the gaze time, and the greater the interest in the color matching of the area 43 .…”
