TVSS Guide

TVSS Fundamentals

Tactile-Visual Sensory Substitution (TVSS) converts visual information into tactile stimuli so that people with visual impairments can interpret shapes, space, and movement through touch.

Research on sensory substitution supports that the brain can reassign visual information to the tactile cortex, enabling new learning pathways.

From Theory to Tukii

Tukii applies TVSS by translating stories and figures into tactile trajectories on the hand. This connects academic theory with emotional and mathematical learning.

The approach combines auditory storytelling, tactile feedback, and guided practice to improve autonomy and spatial memory.
