This research tries to survey the estimates of the importance of information displayed to consumers before purchasing a product, using expected results from an eye-tracking device as a behavioral insight method. This study combines measurement by eye tracker and an individual interview survey; the participant is equipped with an eye-tracking device, and the control group (participants without time constraints) and the intervention group (participants with time constraints) are set. Then, the degree of importance placed on the displayed information when a product is bought is estimated using biometrics data. Firstly, the consumer's gaze fixation on the area of interest in the indicated product information, including the participant is presented with two graphic labels, and the Carbon Dioxide Emissions and the Organic Cultivation are measured, for comparison and evaluation. Judgment is made by demonstrating the cognitive process and attention to a specific element. Then, looking at the consumption information that was paid attention to by the presence or absence of time constraints. No statistically significant differences were found in most of the displayed information, however, the Nutrition Value was displayed with a significant trend (10%). The time looking at the label was 0.93 secs without time constraints, but only 1/3 (0.30 secs) with them. In purchase status, no statistically significant difference was detected with them at Carbon Dioxide Emissions, however, the Organic Cultivation in the amount of gaze information and the number of gazes by purchasers.
