MIT Media Labs Invents Digital Walking Maps
"The software was developed by the Media Labs [Europe] team to overcome the shortcoming of normal maps to give you an idea of how long it would take you to get anywhere... The researchers say it could be used in kiosks at hotels or tourist information centres by visitors trying to work how much they can squeeze into their day.The software could also be adapted for use on handheld computers that you can carry around. Combined with a GPS system, it could then tell you exactly where you are and track you as you walk through a city. "
