Increase / Researchers from the Bielefeld University of Germany used corrective measures to test effects. The number of participants in the study was expressed Mona LisaThe look was directed.

It has been long since the anecdotal reports are their eyes Mona Lisa– Contemporary artist from the renowned Leonardo da Vinci painter, although sometimes the spectators are moving around artwork. The phenomenon is also called "Mona Lisa Effect". But a new study published in the journal i-perception He actually found "looking" at the right side of his audience.

"There is no doubt about the existence of the Mona Lisa effect," wrote the authors. "It does not happen Mona Lisa His head ".

The research carried out on-going studies at the German University of Bielefeld, robots and avatars with human communication. A look-up is crucial when designing game avatars or virtual agents, for example. In this way, an avatar / agent may pay attention, perhaps for the player / user who is tasked with important tasks.

The author of Sebastian Loth sees the effects of Mona Lisa on robots and avatars, and said he is "unavoidable and provable." It's very strong. "Without a doubt, we do not have the right to be faced with the image," he said. "The impression is generated from left to right and from different distances from left to right".

Since 1960, perceptual psychologists have found it very good to see someone look at us, according to Gernot Horstmann, secretary, eye movement and specialized care. "Looks at and shows a great desire to be someone's attention center, to be important to anyone, even if nobody knows," he said. It captures a pleasant feeling of drawing or photographing when it is usually when the image is viewed directly at an angle of 0 to 5 degrees.

Among the various investigations, this happens Mona Lisa (aka The Mona Lisa), the authors claim, failed to mention the conventional evidence of the phenomenon. So they decided to try them out. As far as the direction of this view has not been measured, it is not feasible, Horstmann and Loche looked at the experiment to measure the selected line.

It was a small study, only 24 subjects. They could all ask for a high-resolution recreation look Mona Lisa On the computer monitor, folded ruler between them and the guidance of viewing the screen distances. The matter would be a sign that they perceived Mona LisaLooks at the ruler. The famous portrait of the 15 celebrated sections of the researchers Mona LisaThe whole head from the eye and the nose, and ordered each picture three times randomly. They vary the distance of the model through mid-level sessions.

According to the 2000 individual evaluations, they did not demonstrate the effect of Mona Lisa with Leonardo's masterpiece. "We have proved this Mona Lisa It looks at the left look [the viewer’s right] Approximately 35.5 cm in the pictorial space and the right side of the real space of 14.4 degrees, "authors have written". Thus, Mona Lisa Does not meet the Mona Lisa's effect. It does not look at the audience. "

This is not the first time the scientists have intrigued Mona Lisa It causes human perception. Back in 2015, scientists at the University of Sheffield Hallam in the UK published a paper Visual Research They predicted the Mystery Mona LisaIt's an enigmatic wonder, "now you see, now, no" smile. "Optical illusion is through Leonardo's intentionally created sfumato ("soft" or "pale") the coloring and shading of the mouth.

The viewer can see the slight smile from one distance to another (or digitally it blurs). But this smile disappears in close proximity or if the viewer is centered on his mouth. The Sheffield team found the same effect painted earlier by a master revival, The Princess Bella.

"Master Leonardo's technique and use it later Mona Lisa, it is quite understandable that the ambiguity of the effect was intentional, "said Alessandro Soranzo, psychologist and co-official Telegraph At that time, it was mainly one of the principles of the painter whose portraiture had to "reflect the inner curves of the mind".

I think Leonardo's perceptive scientists may have a great deal of accomplishment.
