Developing humanoid robot animations in motion capture

Great short movies are getting lost amidst thousands of unseen little pieces out there that never get distributed. Synapse and Fantasia film festival attempt to correct this by releasing a compilation of the best and most striking sick little shorts from the past few years.

Fact, Fiction, and Prediction, written by Jasia Reichardt[6] thus forging an unintended link to Ernst Jentsch 's concept of the uncanny[7] introduced in a essay entitled "On the Psychology of the Uncanny. However, as the robot's appearance continues to become less distinguishable from a human being, the emotional response becomes positive once again and approaches human-to-human empathy levels.

The name captures the idea that an almost human-looking robot seems overly "strange" to some human beings, produces a feeling of uncanninessand thus fails to evoke the empathic response required for productive human—robot interaction. Automatic, stimulus-driven appraisals of uncanny stimuli elicit aversion by activating an evolved cognitive mechanism for the avoidance of selecting mates with low fertilitypoor hormonal healthor ineffective immune systems based on visible features of the face and body that are predictive of those traits.

Uncanny stimuli may activate a cognitive mechanism that originally evolved to motivate the avoidance of potential sources of pathogens by eliciting a disgust response.

Stimuli with human and nonhuman traits undermine our sense of human identity by linking qualitatively different categories, human and nonhuman, by a quantitative metric, degree of human likeness.

The uncanny valley may "be symptomatic of entities that elicit a model of a human other but do not measure up to it". However, if the entity looks almost human, it elicits our model of a human other and its detailed normative expectations. The nonhuman characteristics are noticeable, giving the human viewer a sense of strangeness.

In other words, a robot stuck inside the uncanny valley is no longer judged by the standards of a robot doing a passable job at pretending to be human, but is instead judged by the standards of a human doing a terrible job at acting like a normal person. This has been linked to perceptual uncertainty and the theory of predictive coding.

The existence of artificial but humanlike entities is viewed by some as a threat to the concept of human identity. Yalom explains that humans construct psychological defenses in order to avoid existential anxiety stemming from death. One of these defenses is specialness, the irrational belief that aging and death as central premises of life apply to all others but oneself.

In folklore, the creation of human-like, but soulless, beings is often shown to be unwise, as with the golem in Judaism, whose absence of human empathy and spirit can lead to disaster, however good the intentions of its creator.

The negative effect associated with uncanny stimuli is produced by the activation of conflicting cognitive representations. Perceptual tension occurs when an individual perceives conflicting cues to category membership, such as when a humanoid figure moves like a robot, or has other visible robot features.

This cognitive conflict is experienced as psychological discomfort i. Mathur and Reichling found that the time subjects took to gauge a robot face's human- or mechanical-resemblance peaked for faces deepest in the uncanny valley, suggesting that perceptually classifying these faces as "human" or "robot" posed a greater cognitive challenge.

Burleigh and colleagues demonstrated that faces at the midpoint between human and non-human stimuli produced a level of reported eeriness that diverged from an otherwise linear model relating human-likeness to affect. It has been argued that the effect is driven by categorization difficulty, [28] [29] perceptual mismatch, [32] [33] [34] frequency-based sensitization, [35] and inhibitory devaluation.

Negative reactions toward very humanlike robots can be related to the challenge that this kind of robot leads to the categorical human — non-human distinction.

Kaplan [36] stated that these new machines challenge human uniqueness, pushing for a redefinition of humanness. MacDorman and Entenzari [37] investigated the distinction of human and robots as an individual trait that can predict sensitivity to the uncanny valley phenomenon.

Ferrari, Paladino and Jetten [38] found that the increase of anthropomorphic appearance of a robot leads to an enhancement of threat to the human distinctiveness and identity. The more a robot resembles a real person, the more it represents a challenge to our social identity as human beings.

Research[ edit ] A series of studies experimentally investigated whether uncanny valley effects exist for static images of robot faces. They asked subjects to explicitly rate the likability of each face.Human motion capture is a promising technique for the generation of humanoid robot motions.

To convert human motion into humanoid robot motion, we need to relate the humanoid robot kinematics to the kinematics of a human performer. The Sci-Fi Modular Floor Workflow.

Starting with the normal map baking process in 3ds Max, this tutorial will cover creating color and spec maps, setup a floor material in UDK, and finally add lights and decals. Significant Energy E vents in Earth's and Life's History as of Energy Event.

Motion capture (also Mocap) is a way to digitally record human movements. The recorded motion capture data is mapped on a digital model in 3D software (e.g. Unreal Engine, Unity 3D, Maya or 3D Studio Max) so the digital character moves like the actor you recorded.
