Tactile Graphics

Visual information represented in a form that can be perceived through touch, enabling people who are blind or have low vision to access images, diagrams, maps, charts, and spatial layouts. Tactile graphics can be created through embossing, thermoforming, 3D printing, or swell paper (microcapsule paper that raises when heated). Effective tactile graphics require simplification of visual content, clear texture differentiation, appropriate scale for finger exploration, and often accompanying Braille or audio labels. They are essential for STEM education, wayfinding, and understanding spatial relationships that cannot be adequately conveyed through text descriptions alone.
