Tactile Stimulation

Tactile stimulation refers to the use of physical sensations delivered to the skin to convey information, typically through vibrations, pin arrays, textures, or pressure changes. In assistive technology, tactile stimulation is fundamental to braille displays, haptic interfaces, and vibrotactile devices that communicate data through touch. This includes both static patterns (such as raised braille dots) and dynamic effects (such as vibrations indicating transitions or textures representing different interface elements), enabling users who are blind or have low vision to perceive spatial layouts, text content, and interactive feedback without relying on visual output.
