Abstract:
An interior building sign for assisting sighted and visually impaired or blind persons to locate an escape route from point A to point B includes a first planar sheet printed in a first color with a floor plan corresponding to a building floor on which the sign is to be posted. The floor plan is also printed with two dimensional marks in a contrasting color indicating a route from point A to point B. A second planar sheet of substantially transparent material overlies the first planar sheet, the second planar sheet having three dimensional marks machined or routed thereon in substantially overlying relationship with the two dimensional marks to thereby provide a tactile representation of the route. Signs of similar construction have application in non-emergency situations and in other environments including, for example, convention centers, parks and the like.
