Microsoft have issued a patent, which is actually quite interesting. It's dubbed "pedestrian route production", which is known to us simple folk as walking directions, and it will automatically adjust the route for the unique conditions encountered by a person going from place to place on foot.
One of its unique features would help pedestrians navigate around, and not through, "unsafe neighborhoods", with the system taking into account violent crime data. The patent states that the system could "construct a direction set that allows the user to take paths that take him to his home in a quickest amount of time while keeping the user relatively safe (e.g., taking the user through neighborhoods with violent crime statistics below a certain threshold)."
The system would also be capable of taking into account user tolerance for unsafe neighborhoods based on past behavior, such as whether the person has "historically cared about safe neighborhoods."
Other features could allow users to avoid open areas that can subject users to harsh temperatures. It sounds like a next-gen GPS or Google Maps, and like Katy Perry and her thoughts on kissing a girl, "I like it".
