"Atlas is a talking digital map consisting of most addresses and street intersections, nationwide, with a specially designed user interface to navigate and describe this map data verbally using right left, front back, the clock face, compass or 360 degree headings. Arrow keys are used to navigate around the map while a speech synthesizer announces as much or little information as the user wants to hear."
