Tactilization

The process of converting visual or abstract information into tactile representations that can be perceived through the sense of touch. In accessibility, tactilization transforms content such as web page layouts, data visualizations, or text emphasis into patterns of vibration, raised surfaces, or other physical stimuli delivered through tactile displays or refreshable braille devices. Tactilization complements sonification by providing an alternative non-visual channel for conveying spatial, structural, or emphasis information to blind and visually impaired users.
