This invention uses a family of exit-finding aids (100) to enable occupants of rooms or workspaces in buildings, cabins in ships, seats in aircraft cabins, auditoriums, theaters, etc., to know the distance and direction to the nearest exit in each direction by touch as well as by sight; to know so before leaving those spaces; to similarly know the distance and direction to alternate exists along the escape path; to similarly confirm arrival at an exit; and to similarly know the distance and direction to alternative exits from the exit or the escape path if that exit or escape path is unusable. The aids (100) include directional symbols (124, 144) and distance indicating symbols (126, 146).
