Abstract
An apparatus, system, and method provides blind and vision impaired (B/VI) persons with improved Detectible Guidance Markers (DGMs) for navigation in a wide variety of environments, providing information regarding the presence, type, direction, and proximity of various navigational obstacles. A representative but non-exclusive example of an invented unitary DGM includes a plurality of tactually-detectable informational members, including a base member and one or more integral directional members configured to be disposed at a surface of a navigational substrate. A discrete number of directional members conveys an obstacle identity, while different lengths of directional members, and characteristics of other informational members, convey a direction and/or a proximity to an obstacle. Additionally, numerous structural alterations to a surrounding substrate surface cooperatively supplement the detectability and information-conveying benefits of a DGM.
