Tactile paving (also called truncated domes, detectable warnings, Tactile Ground Surface Indicators, detectable warning surfaces) is a system of textured ground surface indicator found on footpaths, stairs and train station platforms to assist pedestrians who are blind or visually impaired.

Tactile warnings provide a distinctive surface pattern of truncated domes, cones or bars detectable by long cane or underfoot which are used to alert the visually impaired of approaching streets and hazardous surface or grade changes. There is a disagreement in the design and user community as to whether installing this aid inside buildings may cause a tripping hazard.
