GPS (global positioning system) software enables people who are blind or visually impaired to navigate to a desired street address or destination. Unlike GPS hardware, these software packages will generally run on a variety of devices rather than on a single device. Depending on the software, directions may be provided through speech, text, or braille. Additional features may include information on points of interest, altitude, speed, and exact GPS coordinates.

BrailleNote GPS
GPS system that runs on the BrailleNote and VoiceNote electronic notetakers. Allows user to automatically create routes for either walking or riding in a vehicle; understand street layout before traveling to a new city, using the "virtual explore" mode; generate detailed information about speed, direction, and altitude; and calculate the distance and direction to a street address or intersection.
