valósidej

Valósidej is a theoretical concept used in discussions of time perception, real-time processing, and synchronization. It designates the state in which an agent's perception or computation operates with negligible latency relative to external events, creating the impression that observations and actions occur in real time. The term is used primarily in theoretical literature and, occasionally, in science fiction to explore the boundaries between observed reality and computational models.

Etymology and scope: The term functions as a neologism often described as originating from the roots of languages for "real" and "time," and is employed more broadly as a general label in English-language discourse. It does not have a formal standard definition, and different authors describe valósidej in slightly different ways. In common usage, it refers to a latency threshold or a synchrony condition between external states and internal representations that makes processing effectively contemporaneous with events.

Applications: In real-time systems engineering, valósidej is invoked as a framework to discuss how closely an ongoing process must track the current state to be considered real-time. In cognitive science and human-computer interaction, it is used to analyze subjective immediacy of perception. In virtual reality and robotics, the concept helps frame requirements for input–output latency, prediction, and synchronization.

Criticism and limitations: Some observers argue that valósidej is ill-defined or tautological, varying with measurement conventions. Others warn that conflating subjective experience with objective latency can obscure practical engineering criteria. Without standardized metrics, the term remains a heuristic rather than a formal category.
