Summary

The Uncanny Valley is a psychological and aesthetic hypothesis describing the relationship between the degree of an object's resemblance to a human being and the emotional response it evokes. First proposed by Japanese roboticist Masahiro Mori in 1970, the concept suggests that as a robot or animated character becomes more human-like, observers' affinity for it increases until a point is reached where the figure appears almost human but is slightly off, causing a sharp drop into a valley of revulsion, eeriness, or cognitive dissonance. In contemporary discussions, the concept is frequently applied to the evolution of AI video generation, such as OpenAI's Sora, and the historical efforts of animation studios like Pixar to achieve realistic human representation without unsettling the audience.

  • Uncanny valley - Wikipedia

    This interval of repulsive response aroused by a robot with appearance and motion between a "somewhat human" and "fully human" entity is the uncanny valley effect. Viewer perception of facial expression and speech and the uncanny valley in realistic, human-like characters intended for video games and movies is being investigated by Tinwell et al., 2011. A summary of Angela Tinwell's research on the uncanny valley, psychological reasons behind the uncanny valley and how designers may overcome the uncanny in human-like virtual characters is provided in her book, *The Uncanny Valley in Games and Animation* by CRC Press. * The uncanny valley effect occurs at any degree of human likeness.

  • What Is the Uncanny Valley? - IEEE Spectrum

    The uncanny valley phenomenon is an eerie or unsettling feeling that some people experience in response to not-quite-human figures like humanoid robots and lifelike computer-generated characters. The uncanny valley graph created by Masahiro Mori: As a robot’s human likeness (horizontal axis) increases, our affinity towards the robot (vertical axis) increases too, but only up to a certain point. That’s the uncanny valley.IEEE Spectrum (original by Masahiro Mori). In an interview with *IEEE Spectrum*, Mori explained how he came up with the idea for the uncanny valley:. “Even though the facial expression is sophisticated and intuitive in this infant robot, I still perceive a false smile when I’m expecting the baby to appear happy,” says Angela Tinwell, a senior lecturer at the University of Bolton in the U.K. and author of *The Uncanny Valley in Games and Animation*. * Ode to the Uncanny Valley - IEEE Spectrum ›.

Mori argued that movement intensifies the uncanny; thus, the curve of the line for moving objects is much steeper, reaching both higher and lower levels of affinity than the line for still objects. Some researchers have noted that the uncanny valley is more of a “cliff,” concluding that the drop and subsequent rise in affinity is more sudden than gradual. Research involving robots has shown that the effects of the uncanny valley may lessen after interaction with the robot, indicating that the phenomenon may be rooted in appearance rather than behaviour. Efforts toward identifying the cause of the uncanny valley are similarly varied.

  • Uncanny Valley: Examples, Effects, & Theory

    > The uncanny valley is a theory in aesthetics suggesting a humanoid object appearing almost, but not exactly, like a real human can evoke feelings of eeriness or revulsion, rather than familiarity, due to the object’s proximity to reality yet noticeable imperfections. 1. Realistic robots or androids that mimic human appearance and movement, but aren’t completely convincing, often trigger the uncanny valley. For example, if a humanoid robot falls into the uncanny valley, humans may be less likely to empathize with it or trust it, limiting the effectiveness of its interactions. According to this proposition, robots and androids in the uncanny valley may resemble human organisms with defects. Research suggests that the deeper a robot’s face is in the uncanny valley, the longer an observer takes to gauge whether the face is actually human or not, and therefore, the greater cognitive challenge the observer encounters in categorizing the visual stimulus (Mathur & Reichling, 2016).

In it, Mori theorized that human-like objects, such as robots, become more appealing the more “real” they look; however, there is a point in which they look “too real” and enter into the uncanny valley. WHY DOES UNCANNY VALLEY HAPPEN? The uncanny valley happens because our minds are wired to recognize and empathize with humans – but when something looks human yet lacks the essential subtleties of a real person, our brains register it as wrong. In these cases, humans hyper-fixate on small details that don't reach perfect verisimilitude, such as the rate at which robots blink their eyes, or the speed at which they move their limbs. THE UNCANNY VALLEY EFFECT IN FILM The uncanny valley effect is used by filmmakers to creep out the audience. This can be done a myriad of ways; for example: zombie movies feature monsters that appear human at a distance, but become uncanny when we notice their unusual movements. The 2022 film M3GAN featured a doll-like robot that terrified moviegoers; the Megan uncanny valley was most often entered when audiences noticed the character's unnatural facial movements, inhuman eyes, and blood-curdling mannerisms. UNCANNY VALLEY EXAMPLES The uncanny valley is a huge topic in robotic research. Companies hoping to create androids that are indistinguishable from humans have to contend with the how the slightest of imperfections can shock (and even repulse) potential customers. CGI artists also struggle with the uncanny valley; for example: the 2019 film Cats received poor reviews largely because its oddly anthropomorphic felines unsettled audiences. In the years since Mori's inception, the uncanny valley has been studied by countless researchers and academics. Not everybody agrees with Mori's theory; some critics argue that culture, age, and experience significantly alter subjective interpretations of the uncanny valley. Moreso, the uncanny valley is easy to avoid; robotocists and artists can incorporate "cartoonish" elements in their work to stop short of entering the uncanny valley. Still, the uncanny valley can be purposefully invoked by anybody hoping to terrify their audience. #FilmTheory #VideoEssay #Filmmaking ───────────────────── ♬ SONGS USED: “Trevor’s Lair” - Roque Baños “Sleepless” - Roque Baños “Red Bat With Teeth” - Angelo badalamenti “Anthem” - Michael Abels “The Spectacle Is Repeated” - Shiro Sato “The Chapel” - John Frizzell “8” - Donald Rubenstein “Tape Deck” - Charlie Clouser “Lights Out” - John Carpenter “No Male Visitors” - Steven Price “Bulletin Board” - Craig McKay “Les Yeux Sans Visage” - Maurice Jarre “The Test Worked” - Ben Salisbury “Smile” - Nat King Cole “Angel of Death” - Denny Zeitlin “Humanity Pt. 2” - Ennio Morricone “Tubular Bells” - Mile Oldfield Music by Artlist ► https://utm.io/umJx Music by MusicBed ► http://bit.ly/2Fnz9Zq ───────────────────── SUBSCRIBE to StudioBinder’s YouTube channel! ►► http://bit.ly/2hksYO0 Looking for a project management platform for your filmmaking?
