Navigation App Gives You Freedom to Explore
Swansea University's Simon Robinson and colleagues have developed a smartphone navigation application that gives pedestrians the opportunity to explore unfamiliar cities without getting lost. The app is designed to provide general directions for reaching a geographical target, but leaves the precise route open to the user. The smartphone will vibrate when it is pointed toward the destination.
The system uses location information and mapping software to constantly analyze the available routes, widen or shrink the field of possible routes, and provide vibrational feedback. "We're not trying to replace turn-by-turn navigation," Robinson says. "But sometimes it's nice not to know exactly where you are."
