Estimating the term…
A device of any material, shape, size, texture, style, color, configuration, and orientation that is affixed, secured, or is an integral part to a staircase handguide, to a handguide support or frame, or to a sidewall. The device provides anyone, ascending or descending the stairs, with a tactile cue that indicates the pedestrian's approach to a final step in a series of steps. A pedestrian senses the tactile indicator to determine when he or she is at the last step so as to change accordingly his or her walking or motion. This safety indicator is intended for the public at large. A pedestrian without sight, with impaired or limited sight, or with compromised sight (due to power outage, light-source outage, smoke-filled stairwell, temporary blindness, etc.) can negotiate stairs with greatly increased safety, speed, and confidence.
