The project comes from a study by Yarbus, 1967 [eye movement and vision] “Depending on the task in which a person is engaged, i.e., depending on the character of the information which he must Obtain, the distribution of the points of fixation on an object will vary correspondingly. because different items of information are usually localized in different parts of an object. ” Yarbu’s research used Repin’s painting “An unexpected visitor” to study gazing behaviors by posing different questions to the gazer. For instance, the researcher asked the gaze to"estimate the material circumstances of the family shown in the picture," in response to which the observer would pay particular attention to the women's clothing and the furniture (the armchair, stool, table chloth, and so on). And following the instruction to “give the ages of the people shown in the picture," the observe would focus on the painted faces.

Coutrot et al. 2016 has a similar study that demonstrated by giving the gaze pattern behaved on human’s portrait, people can predict the object’s gender. The study probe the temporal dynamics of gaze to explore what information can be extracted about the observers and what is being observed. The results show that female gazers follow a much more exploratory scanning strategy than males. Moreover, female gazers watching female actresses look more at the eye on the left side.

These studies illustrate that human gaze behavior contains much invisible information, both observers and what is being observed, like their emotion, attitude, thought, and judgment. In the project, artist chose four most common judgments (beauty, wealth, morality, and intellect) to collect gaze patterns according to these questions. What are they and who or what has the power to define them? No matter whether individual or society, gaze behavior will provide the answer.
