Voice guided GPS or A-GPS has become a very common feature for mobile phone as well and is handy while driving. The voice commands tell you the estimated distance of travel and where to take turns. It also guides you through the shortest route possible. It even recalculates the distance if by chance you dont follow the voice command.
Almost all GPS enabled mobile phones these days come with voice command. Also dedicated GPS devices have same features but are faster. A common feature of GPS is a location-based search commonly known as LBS. It enables you to search nearby Point of Interests (POIs) using GPS.
just imagine
GPS technology has a lot of advantages. In the near future mobile phones will also be able to hold/integrate a high-end 3D mapping GPS application. With further evolution, who knows one day your car might drive by itself using GPS and all you would need to do is sit back and relax. Wondering when this would happen? We wish... very soon.
