EmotionCan

EmotionCan refers to a proposed standardized representation for encoding and exchanging emotional state information in digital systems, including interactive agents, animation pipelines, and multimedia content. The term is used in discussions of affective computing to describe a portable, machine-readable way to convey perceived or intended affect without prescribing a particular platform.

A typical EmotionCan model combines quantitative axes with qualitative labels. Commonly, valence and arousal are used to represent relative pleasantness and intensity, sometimes extended with dominance or power. A discrete emotion label (such as joy, fear, or sadness) and an intensity value may accompany the axes. Additional fields may capture modality cues (tone of voice, facial expression, gestural cues), context, and the actor's action tendency or coping strategy. The design emphasizes portability and interoperability across devices, software libraries, and content pipelines.

Practically, EmotionCan can be realized as a schema or ontology encoded in a JSON- or XML-based format, with versioning, optional metadata, and security considerations. It is intended to complement existing affective computing tools such as emotion recognition and emotion synthesis, enabling consistent tagging, transmission, and rendering of emotional information.

Potential applications include conversational agents that adjust dialogue and tone, animated characters that display believable affect, and multimedia systems that synchronize music, lighting, and visuals with emotional cues. It is also discussed in contexts such as accessibility and mental health technology.

Status and critique: EmotionCan is a theoretical construct rather than a universally adopted standard. Variability in cultural conceptions of emotion, individual differences, and privacy concerns pose challenges to universal adoption. Critics emphasize the risk of oversimplification and misinterpretation when relying on a fixed representation of affect.
