Haptic Graphics

Graphical information presented through the sense of touch, typically on refreshable displays or touchscreen devices. Unlike static tactile graphics (embossed paper or thermoform), haptic graphics can change dynamically and often combine tactile feedback with audio cues. Modern implementations include pin-matrix displays that physically raise and lower pins, and touchscreen-based solutions using vibrotactile motors to simulate tactile textures. Haptic graphics enable blind and visually impaired users to access maps, charts, diagrams, and other visual information that text-to-speech cannot adequately convey, as spatial relationships are perceived directly rather than requiring cognitive translation from verbal descriptions.
