PAD Emotional State Model
The PAD emotional state model is a psychological model developed by Albert Mehrabian and James A. Russell (1974 and after) to describe and measure emotional states. PAD uses three numerical dimensions, Pleasure, Arousal and Dominance to represent all emotions. Its initial use was in a theory of environmental psychology, the core idea being that physical environments influence people through their emotional impact. It was subsequently used by Peter Lang and colleagues to propose a physiological theory of emotion. It was also used by James A. Russell to develop a theory of emotional episodes (relatively brief emotionally charged events). The PA part of PAD was developed into a circumplex model of emotion experience, and those two dimensions were termed "core affect". The D part of PAD was re-conceptualized as part of the appraisal process in an emotional episode (a cold cognitive assessment of the situation eliciting the emotion). A more fully developed version of this approach ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Psychology
Psychology is the scientific study of mind and behavior. Psychology includes the study of conscious and unconscious phenomena, including feelings and thoughts. It is an academic discipline of immense scope, crossing the boundaries between the natural and social sciences. Psychologists seek an understanding of the emergent properties of brains, linking the discipline to neuroscience. As social scientists, psychologists aim to understand the behavior of individuals and groups.Fernald LD (2008)''Psychology: Six perspectives'' (pp.12–15). Thousand Oaks, CA: Sage Publications.Hockenbury & Hockenbury. Psychology. Worth Publishers, 2010. Ψ (''psi''), the first letter of the Greek word ''psyche'' from which the term psychology is derived (see below), is commonly associated with the science. A professional practitioner or researcher involved in the discipline is called a psychologist. Some psychologists can also be classified as behavioral or cognitive scientists. Some psychol ...

Wilhelm Wundt
Wilhelm Maximilian Wundt (; ; 16 August 1832 – 31 August 1920) was a German physiologist, philosopher, and professor, known today as one of the fathers of modern psychology. Wundt, who distinguished psychology as a science from philosophy and biology, was the first person ever to call himself a psychologist. He is widely regarded as the "father of experimental psychology"."Wilhelm Maximilian Wundt" in ''Stanford Encyclopedia of Philosophy''. In 1879, at the , Wundt founded the first formal laboratory for psychological research. This marked psychology as an independent field of study. By creating this laboratory he was able to establish psychology as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Emotion
Emotions are mental states brought on by neurophysiology, neurophysiological changes, variously associated with thoughts, feelings, behavioral responses, and a degree of pleasure or suffering, displeasure. There is currently no scientific consensus on a definition. Emotions are often reciprocal determinism, intertwined with mood (psychology), mood, temperament, personality psychology, personality, disposition, or creativity. Research on emotion has increased over the past two decades with many fields contributing including psychology, medicine, history, sociology of emotions, and computer science. The numerous theories that attempt to explain the origin, functional accounts of emotion, function and other aspects of emotions have fostered more intense research on this topic. Current areas of research in the concept of emotion include the development of materials that stimulate and elicit emotion. In addition, positron emission tomography, PET scans and functional magnetic re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Journal Of Experimental Psychology
The ''Journal of Experimental Psychology'' was a bimonthly peer-reviewed academic journal published by American Psychological Association. The journal, established in 1916, contained articles relating to experimental psychology. Beginning in 1975, three independently edited and distributed sections were split off with an additional section being added in 1995. The ''Journal of Experimental Psychology'' was renamed '' Journal of Experimental Psychology: General''. History The first issue of the journal was published by the Psychological Review Company, Princeton, New Jersey Princeton is a municipality with a borough form of government in Mercer County, in the U.S. state of New Jersey. It was established on January 1, 2013, through the consolidation of the Borough of Princeton and Princeton Township, both of w ....

Face Animation Parameter
A Face Animation Parameter (FAP) is a component of the MPEG-4 Face and Body Animation (FBA) International Standard (ISO/IE14496-1 developed by the Moving Pictures Experts Group. It describes a standard for virtually representing humans and humanoids in a way that adequately achieves visual speech intelligibility as well as the mood and gesture of the speaker, and allows for very low bitrate compression and transmission of animation parameters. FAPs control kefeature pointson a face model mesh that are used to produce animated visemes and facial expressions, as well as head and eye movement. These feature points are part of the Face Definition Parameters (FDPs) also defined in the MPEG-4 standard. FAPs represent 66 displacements and rotations of the feature points from the neutral face position, which is defined as: mouth closed, eyelids tangent to the iris, gaze and head orientation straight ahead, teeth touching, and tongue touching teeth. These FAPs were designed to be closel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
MPEG-4
MPEG-4 is a group of international standards for the compression of digital audio and visual data, multimedia systems, and file storage formats. It was originally introduced in late 1998 as a group of audio and video coding formats and related technology agreed upon by the ISO/IEC Moving Picture Experts Group (MPEG) ( ISO/IEC JTC 1/SC29/WG11) under the formal standard ISO/IEC 14496 – ''Coding of audio-visual objects''. Uses of MPEG-4 include compression of audiovisual data for Internet video and CD distribution, voice (telephone, videophone) and broadcast television applications. The MPEG-4 standard was developed by a group led by Touradj Ebrahimi (later the JPEG president) and Fernando Pereira. Background MPEG-4 absorbs many of the features of MPEG-1 and MPEG-2 and other related standards, adding new features such as (extended) VRML support for 3D rendering, object-oriented composite files (including audio, video and VRML objects), support for externally specified ...

Avatar (computing)
In computing, an avatar is a graphical representation of a User (computing), user or the user's Player character, character or persona. Avatars can be two-dimensional Computer icon, icons in Internet forums and other online communities, where they are also known as profile pictures, userpics, or formerly picons (personal icons). Alternatively, an avatar can take the form of a three-dimensional model, as used in online worlds and video games. The term ' () originates from Sanskrit, and was adopted by early computer games and science fiction novelists. Richard Garriott extended the term to an on-screen user representation in 1985, and the term gained wider adoption in Internet forums and MUDs. Nowadays, avatars are used in a variety of online settings including social media, virtual assistants, instant messaging platforms, and digital worlds such as ''World of Warcraft'' and ''Second Life''. They can take the form of an image of one's real-life self, as often seen on platforms li ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Charles E
Charles is a masculine given name predominantly found in English and French speaking countries. It is from the French form ''Charles'' of the Proto-Germanic name (in runic alphabet) or ''*karilaz'' (in Latin alphabet), whose meaning was "free man". The Old English descendant of this word was '' Ċearl'' or ''Ċeorl'', as the name of King Cearl of Mercia, that disappeared after the Norman conquest of England. The name was notably borne by Charlemagne (Charles the Great), and was at the time Latinized as ''Karolus'' (as in ''Vita Karoli Magni''), later also as '' Carolus''. Some Germanic languages, for example Dutch and German, have retained the word in two separate senses. In the particular case of Dutch, ''Karel'' refers to the given name, whereas the noun ''kerel'' means "a bloke, fellow, man". Etymology The name's etymology is a Common Germanic noun ''*karilaz'' meaning "free man", which survives in English as churl (< Old English ''ċeorl''), which developed its de ...

Virtual World
A virtual world (also called a virtual space) is a computer-simulated environment which may be populated by many users who can create a personal avatar, and simultaneously and independently explore the virtual world, participate in its activities and communicate with others. These avatars can be textual, graphical representations, or live video avatars with auditory and touch sensations. Virtual worlds are closely related to mirror worlds. In a virtual world, the user accesses a computer-simulated world which presents perceptual stimuli to the user, who in turn can manipulate elements of the modeled world and thus experience a degree of presence. Such modeled worlds and their rules may draw from reality or fantasy worlds. Example rules are gravity, topography, locomotion, real-time actions, and communication. Communication between users can range from text, graphical icons, visual gesture, sound, and rarely, forms using touch, voice command, and balance senses. Massively mult ...

Albert Mehrabian
Albert Mehrabian was born in 1939 to an Armenian family living in Iran. He is Professor Emeritus of Psychology at the University of California, Los Angeles.UCLA CollegeProfessor Emeritus, Department of Psychology, UCLA Although he originally trained as an engineer, he is best known for his publications on the relative importance of verbal and nonverbal messages. He also constructed a number of psychological measures including the Arousal Seeking Tendency Scale. Mehrabian's findings on inconsistent messages of feelings and attitudes (the "7%-38%-55% Rule") are well-known, the percentages relating to relative impact of words, tone of voice, and body language when speaking. Arguably these findings have been misquoted and misinterpreted throughout human communication seminars worldwide. Attitudes and congruence According to Mehrabian, the three elements account differently for our liking for the person who puts forward a message concerning their feelings: words account for 7%, ton ...

Animated Character
Character animation is a specialized area of the animation process, which involves bringing animated s to life. The role of a character animator is analogous to that of a film or stage actor and character animators are often said to be "actors with a pencil" (or a mouse). Character animators breathe life in their characters, creating the illusion of thought, emotion and personality. Character animation is often distinguished from creature animation, which involves bringing photorealistic animals and creatures to life. Origins Winsor McCay's '' Gertie the Dinosaur'' (1914) is often considered the first example of true character animation. Later, Otto Messmer imbued Felix the Cat with an instantly recognizable personality during the 1920s. In the 1930s, Walt Disney made character animation a particular focus of his animation studio, best showcased in productions such as ''Three Little Pigs'' (1933), ''Snow White and the Seven Dwarfs'' (1937), ''Pinocchio'' (1940), and ''Dumbo'' ...

Body Language
Body language is a type of communication in which physical behaviors, as opposed to words, are used to express or convey information. Such behavior includes facial expressions, body posture, gestures, eye movement, touch and the use of space. The term body language is usually applied in regard to people but may also be applied to animals. The study of body language is also known as kinesics. Although body language is an important part of communication, most of it happens without conscious awareness. Body "language" must not be confused with sign language. Sign languages are ''literally'' languages: they have (their own) complex grammar systems, and they also are able to exhibit the fundamental properties that are considered to exist in all (''true'') languages. Body language, on the other hand, does not have a grammar system and must be interpreted broadly, instead of having an absolute meaning corresponding with a certain movement, so it is not a language, and is simply termed ...
