Believe the inventions.
I have read information about Global Positioning System or GPS technology. This kind of invention took 4 years of research and analysis. The inventor was Ameen Abdulrasool and his age is only 18. This invention of Abdulrasool helps blind people get around or good mood. Abdulrasool was a University of Illinois student which he claim grand prize including an amount of $50,000 and held at Intel International Science and Engineering Fair in Arizona. $50,000 is not a joke for a young inventor. The invention looks like a black shade. This device is working for blind person needs a sighted person to input a starting and ending point. I have learned a lot in this invention and the young inventor like Abdulrasool.
