Hussain strikes again, with a very interesting presentation on Mobile Navigation.
What do you do if you're on your way to a place that you've never been to before and lose your way? Well.. i go to the nearest rickshaw- walla and say "Uncle .. XYZ Peth kahan hai??" which is not so much fun..and Yes, i say Uncle.
So, a great alternative which we learnt about yesterday is this: Get your cellphone out, point at the nearest building, and receive the info about that building and voila! you know where you are again.
This concept can be extended to pointing to Cinema halls and getting their schedules, booking seats, as well as pointing to restaurants and getting to know the menu and reserving a table!
This is done through satellite communication. The necessary computations to give you the building name are done by a powerful server that receives parameters like latitude, longitude, orientation etc from the satellite. Artificial Intelligence concepts are applied to eliminate the unnecessary elements of your surrounding like ponds etc, and to zero down upon your direction of view.
