Tactiovisual distance-to-exit exit-finding system

摘要

This invention uses a family of exit-finding aids 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 escape paths to each of those exits; to similarly know the distance and direction to alternate exits along the escape path; to similarly confirm arrival at an exit; and to similarly know the distance and direction to alternates to exits that are unusable.
