Although an ideal definition for a designed product is relative, it is primarily related to the appearance of the product. In this research, the focus is on visual perception, which has a great impact on the inner world of users. With the aim of accessing implicit aesthetic appreciation information through the user, eye tracking technology is used as a tool. The purpose of the conducted study is to determine the impact of varying details in the product on appreciation. For this purpose, samples of a furniture product, seats, were selected for an experimental study. 60 participants examined 480 different stylistic details designed for the 40 seats (10 different models * 4 variations) and rated the product while examining. During the examination, the eye metrics were recorded, which produced 230,400 data in total for the analysis. The results provided meaningful and instructive findings regarding the age and gender-focused data of the participants, the effect of product style and detail preferences on user appreciation. Accordingly, the study found that appreciation towards the product details can be read through eyes using certain gaze metrics such as time to first fixation, duration of first fixation, number and duration of fixations, number and duration of visits. In this context, a meaningful data series was obtained regarding which and how the metrics can be used in eye tracking technology, and it was demonstrated that the effect of decisions about the expected product form in early design processes on user appreciation can be addressed with this technology.
