I have seen some of this all demo on android phones. The app tried to do some indoor mapping based on wifi signals. Once the mapping is done it can help you navigate indoors. Pretty impressive though it needs sufficient wifi signals to be around. I would love these kind of apps to be more improved and accurare.
I can imagine that app helping blind people get around indoor areas, easier.
@Mr. Roques, I agree with you. Such apps/system will definitely help blind people get around indoor areas. It will also help people to easily navigate indoors when they find it difficult to find the destination.
I can imagine that app helping blind people get around indoor areas, easier. I don't know the current state of blind people using smart phones, but with voice integration, I can imagine it helping them go through malls, bus and train stations, etc.
I have read about a similar positioning technology that uses a combination of magnetometers, GPS, accelerometer and an electronic compass for indoor positioning.
The idea is to use GPS tracking outdoors and when the coverage is lost indoors the remaining three technologies work together to keep track of things. Obviously, there is an error margine here but this hybrid approach is a move in the right direction for maintaining accurate tracking when indoors.
I think there is a huge potential for positioning indoors. I have not come across a cheap and an accurate indoor positioning system yet.
The Earth's magnetic field once helped pioneering explorers discover exciting new lands and untold riches. Now, it could stop you getting lost at the shops, thanks to an upcoming smartphone app that uses magnetic fluctuations to map indoor locations, guiding you around places that GPS can't penetrate. Do you find such Apps useful and would you want to download such Apps ?
