Tactility and texture are powerful forms of stimulation for the brain, engaging sensory pathways that influence memory, emotion, and perception. The sensation of touch—whether soft, coarse, elastic, or rigid—can trigger deep psychological responses and shape how we interpret space and presence. In XR design, psychological tactility explores how visual, auditory, and kinetic cues can simulate the feeling of touch without physical contact. By studying how the brain responds to implied textures and motion, creators can craft immersive experiences that feel tangible, even in virtual environments. This approach opens new possibilities for empathy, learning, and embodied interaction.
