Tactile Walking Surface Indicators

TufTile offers a complete range of tactile walking surface indicators (TWSIs) designed to provide warning, wayfinding, and boundary cues for pedestrians who are blind or have low vision. Designed to be detected underfoot or with a mobility cane, TWSIs can be used individually or together throughout accessible pedestrian environments.
