# What is Uncanny Valley?

*Artificial Intelligence · Last updated: October 30, 2026*

It is the feeling of eeriness and unease that human-like robots or artificial intelligence creations evoke in the observer at the point where they come very close to a real human without quite reaching it.

## Overview

The uncanny valley is a phenomenon where, as the likeness of an artificial entity to a human increases, the sympathy and affinity felt towards it rises, but at a point very close to the threshold of perfection, it suddenly turns into a sharp revulsion or discomfort. The mechanical nature of eye movements, the dullness in skin texture, or the micro-second artificialities in speech intonation are perceived by our brain as an unusual situation. When the similarity reaches a completely indistinguishable level, this feeling of discomfort disappears and the level of acceptance rises again.

***Analogy:** It is similar to how cartoon characters are viewed as very cute, while some figures in a wax museum create chills because they look too much like humans yet remain lifeless.*

## How it works

The human brain is programmed to analyze micro-details such as facial expressions, eye contact, and voice synchronization within seconds during social interaction. When AI-powered video models or humanoid robots get very close to reality, even the slightest timing error or artificial light reflection triggers the danger detectors in the brain. This biological response requires visual designers and AI developers to make conscious choices between hyper-realism and stylized designs.

## Where it is used

It appears in AI-generated virtual anchors, realistic digital human models in video games, humanoid robot design, and deepfake technologies.

## Commonly confused with

It is different from poor-quality AI productions; the uncanny valley stems not from low quality, but from getting too close to reality while missing human naturalness in a minor detail.

## Questions and answers

**How is the uncanny valley feeling overcome in AI-generated videos?**

It is overcome by perfecting the micro-twitches of eye movements, the natural breathing rhythm, and lip-voice synchronization, or by intentionally choosing slightly stylized visual styles.

**Does this concept apply only to physical robots?**

No. Although it was originally coined for robotics, today it also applies to photographs, videos, digital characters, and synthetic voices generated by artificial intelligence.
