Barry Brown is with the Mobile Life Centre in Stockholm，Sweden.He told us about an incident involving a friend who had flown to an airport in the eastern United States.There he borrowed a GPS­equipped car to use during his stay.Mr Brown says，“They just plugged in an address and then set off to their destination.And，then it wasn’t until they were driving for thirty minutes that they realized they actually put in a destination back on the West Coast where they lived.They actually put their home address in.So again，the GPS is kind of ‘garbage in garbage out’．”

　　Mr Brown says this is a common human error，but what makes the problem worse has to do with some of the shortcomings，or failures，of GPS equipment.He says，“One problem with a lot of the GPS units is they have a very small screen and they just tell you the next turn.Because they just give you the next turn，sometimes that means that it is not really giving you the overview that you would need to know that it’s going to the wrong place.”

　　Mr Brown says，“One of the things that struck us，perhaps the most important thing was that you have to know what you’re doing when you use a GPS.There are these new skills that people have developed.There are these new competencies (资格) that you need to have to be able to use a GPS because they sometimes go wrong.This goes against a common belief that GPS systems are for passive drivers who lack navigational skills.”
