The CLS system provides a means to create thousands of points of interest using georeferencing (Latitude/Longitude) gathered in a variety of ways. In the simplest cases by field-gathering, in the ideal digital capturing from existing sources such as Transit Systems, City GIS systems, other mapping-sources. When made available, the traveler using BlindSquare is automatically apprised of information of value when entering the proximity of the POI’s (Points of Interest). The scope and use-cases are vast. From campus information, to trails (in-city, rural and wilderness, parks and vista’s) where the traveler, even when traveling with persons with sight, is informed and possibly to a degree greater than what’s apparent by sight. Information conveyed, in every instance, is presented in two tiers. Tier 1 - baseline confirmation of current location which can be directionally sensitive. Tier 2 - presented on request, can unlock detailed information matching the degree of benefit to the travelers.
Note: The accuracy of GPS outdoors is typically 5 meters. The practical benefit is improved with cane-detectable identifiers such as sidewalks or other shorelines, and other cane-detectable features like stairways, ramps, railings or tactile street markings such as tiles with truncated domes. The practical benefit is further extended by the use of direction of travel and an accurate heading determined by algorithm.
