Humans usually favor the company of beings similar to them and it is therefore natural to assume that with increasing human likeness, robots and artificial characters become more likeable and accepted. However, this is only true up to a point where the dynamic is reversed and synthetic characters appear uncanny. Thus, increased realism does not necessarily lead to an increase in acceptance. This phenomenon is called the "Uncanny Valley" and was first proposed by Masahiro Mori in 1970. It has recently sparked more interest due to advancements in robot development and computer animation and therefore a potential relevance in the robot, movie and video game industries as well as for scientific computer simulations. The theory of the Uncanny Valley is not undisputed, which is why this paper aims to present both evidence in favor and arguments against its existence or interpretation. Furthermore, the phenomenon shall be examined in more detail, investigating its backgrounds, possible explanations, influencing factors and its consequences on android design. Among the issues to be further investigated that were found in the discussion are alternative stimuli, the empirical measurement of the uncanny response, a universal categorization system, and the usefulness of the Uncanny Valley as a design guide. There are indications that the relationship between human likeness and likeability may not be as clear as proposed by Mori, but more-dimensional with additional factors to consider.

Research Objectives and Core Themes
This paper explores the "Uncanny Valley" phenomenon, investigating its origins, theoretical underpinnings, and implications for artificial character and android design. It addresses the central research question of whether the theory of the Uncanny Valley is valid and how various factors, such as appearance, movement, and context, influence human perception and acceptance of humanoid agents.
- Theoretical analysis of the Uncanny Valley and its proposed mechanisms.
- Evaluation of empirical evidence for and against the existence of the valley.
- Investigation of explanatory approaches including evolutionary psychology and cognitive prediction errors.
- Practical implications and design strategies for creating acceptable humanoid robots.
Excerpt from the Book
2. THE THEORY OF THE UNCANNY VALLEY
The theory of the Uncanny Valley was first introduced by Masahiro Mori in 1970 [21]. It assumes that the likeability of an artificial character or robot steadily increases with its human likeness up to a point where the dynamic reverses and likeability ratings tumble into the Uncanny Valley (see figure 1). In this area, highly developed humanoid robots elicit a feeling of eeriness and the close human likeness becomes a feature with negative effects. After the valley the slope rises again, in order to finally reach the highest point of likeability with complete human likeness – that is to say synonymy with a healthy person.
Mori brought the example of a prosthetic hand that looks but does not feel real, due to differences in temperature and texture, and is perceived as eerie or uncanny. He states that the effect is even worsened by adding movement, with motion as a generally deepening factor of the valley, but also enhancing the peaks (see the dotted line in figure 1). [21] This could be due to the fact that an extra factor of information in perceiving a humanoid robot is also an extra factor that could be wrong in regard to the expectations made and therefore lead to further rejection of the robot [22]. Objects like the Japanese Bunraku puppets, whose false nature is already accepted, can be found more highly on the scale than the aforementioned prosthetic hand, that aims to replace a real one. Trying to conceal the artificialness of a character or object might therefore increase its uncanniness [6].
Summary of Chapters

Frequently Asked Questions
What is the primary subject of this research paper?
The paper examines the "Uncanny Valley" theory, which posits that as robots become more human-like, they initially become more likable until a point where they appear eerie and repulsive, before reaching a high level of likability again upon appearing perfectly human.
What are the central themes discussed in the work?
Key themes include the psychological origins of the Uncanny Valley, the role of human expectation and prediction errors, evolutionary survival instincts, and the influence of appearance and movement on robotic design.
What is the primary research goal?
The goal is to explore the validity of the Uncanny Valley, compare supporting and conflicting scientific evidence, and determine how these findings can be applied to develop better, more accepted humanoid robots.
Which scientific methods are primarily analyzed?
The work reviews a variety of methods including behavioral questionnaires, rating scales, functional magnetic resonance imaging (fMRI) studies, and experiments involving morphed faces and video recordings.
What does the main body of the text cover?
The main body systematically explores the original theory, evidence-based critiques, explanatory models (such as framing theory and evolutionary fear), and specific design recommendations for engineers.
Which keywords characterize this paper?
Key terms include Uncanny Valley, humanoid robot, android design, likeability, cognitive dissonance, and human-robot interaction.
How do cultural backgrounds influence the perception of androids?
The paper notes that Asian cultures, influenced by beliefs such as Shintoism, generally show higher acceptance levels for human-like robots compared to Western cultures, which are more historically skeptical regarding the creation of synthetic life.
Does the author conclude that the Uncanny Valley theory is proven?
No, the author concludes that the theory is heavily disputed and that the results of empirical research remain inconclusive, suggesting that human likeness is only one of many complex factors influencing perception.
