Emotional Expression

Emotional Expression

Emotional expression encompasses how individuals convey their emotions through verbal communication and non-verbal cues. These non-verbal actions include facial expressions, body language, and physical gestures, such as frowning or smiling. Among these, facial expressions play a crucial role in emotional expression and are understood universally, indicating a biological basis for how humans communicate emotions.

Facial Feedback Hypothesis

Facial Feedback Hypothesis

Charles Darwin proposed that facial expressions are an evolutionary adaptation for communication. He argued that these expressions are not influenced by culture but are universal across species. For example, a snarling expression with exposed teeth signals a threat in many animals, including humans. Darwin also suggested that displaying an emotion can intensify the feeling. Smiling, for example, could enhance one's sense of happiness. This idea laid the foundation for understanding the role of...

Therapeutic Communication

Therapeutic Communication

Communication is a lifelong learning process. Through therapeutic communication, nurses can collect relevant assessment data, provide education and counseling, and interact during nursing interventions. Sending and receiving messages occur through verbal and nonverbal communication techniques and can happen separately or simultaneously.
Verbal communication depends on language or a prescribed way of using words so that people can share information effectively. The critical aspects of verbal...

Channels of Non-Verbal Communication

Channels of Non-Verbal Communication

Non-verbal communication plays a critical role in human interaction, influencing how individuals perceive emotions and psychological states. It operates through four primary channels: facial expressions, eye contact, body language, and touch. These non-verbal cues help convey meaning beyond spoken language and are often culturally influenced.Facial Expressions and Emotional RecognitionFacial expressions are among the most powerful and universal forms of non-verbal communication. Research has...

Labeling Emotion

Labeling Emotion

Emotional labeling is a cognitive process that involves identifying and naming one's emotions, such as anger, fear, happiness, or sadness. It allows individuals to recognize and express their internal emotional states, a critical aspect of emotional regulation and communication. Labeling emotions requires more than mere recognition; it also involves drawing upon memory and contextual cues to understand the current situation and apply a corresponding emotional label. For instance, feeling...

Physiological Theories: James-Lange Theory of Emotion

Physiological Theories: James-Lange Theory of Emotion

The James-Lange theory of emotion, proposed by William James and Carl Lange in the late 19th century, asserts that emotions are the result of physiological reactions to external stimuli. Contrary to the traditional view, which suggests that emotions directly arise from the perception of stimuli, this theory proposes that emotions occur as a consequence of the body's responses to such stimuli. According to this framework, an emotional experience is a cognitive interpretation of physiological...

Area of Science:

Computer graphics
Human-computer interaction
Affective computing

Background:

Gaze is a crucial, yet under-researched, nonverbal cue for emotional expression.
Virtual characters require sophisticated models to convey human-like emotional states.

Purpose of the Study:

To introduce the Expressive Gaze Model (EGM), a hierarchical framework for generating emotionally expressive gaze in virtual characters.
To detail the components of the EGM, including the Gaze Warping Transformation (GWT).

Main Methods:

The EGM integrates eye movement models with head and torso dynamics.
The Gaze Warping Transformation (GWT) generates emotionally modulated head and torso movements during gaze shifts.
The framework composes simple behaviors into complex, emotionally expressive gaze patterns.

Main Results:

The EGM has been successfully applied to generate various types of gaze shifts.
The model allows for the creation of expressive gaze with and without explicit emotional behaviors.
Demonstrated the capability of the EGM to produce nuanced emotional expressions through gaze.

Conclusions:

The Expressive Gaze Model provides a robust method for enhancing emotional realism in virtual characters.
The EGM facilitates the generation of diverse and emotionally congruent gaze behaviors.
Further research can leverage the EGM for more sophisticated virtual character animation and interaction.
