Illuusiot

Illuusiot is a term used in contemporary art theory and media studies to describe the intentional creation of perceptual illusions through design, technology, and narrative framing. The concept covers visual, auditory, and multi-sensory effects that cause observers to misjudge size, depth, motion, or identity of objects, often to convey a message or evoke a response. It emphasizes deliberate construction rather than incidental perceptual quirks.

The word is a stylized form of illusion and has emerged in critical and design discourse as a way to group a family of techniques rather than a single phenomenon.

Practitioners include digital artists, game designers, interface designers, and VR/AR developers who use perspective tricks, shading cues, timing, and contextual cues to shape perception. Examples include interactive ambiguous figures, depth illusions that shift with gaze, and audio-visual synchrony manipulations that alter perceived space.

In cognitive science, illuusiot intersects with studies of top-down processing and predictive coding, examining how expectations prime perception. Ethical considerations focus on transparency, user autonomy, and the potential for manipulation in advertising and persuasive design.
