Indoor navigation techniques : a comparative analysis between radio frequency and computer vision-based technologies

Abstract

It has always been a human desire to see how far up into the sky their creation can reach. It is like humanity to push further than ever and create things better than anyone before they only dreamt of. This complexity of achievements achieved by human beings, however, brings forward other challenges that need to be faced by present scientists. When human beings started exploring the enormity of the world, the need to navigate around it arose quickly. From early times we see sailors trying to navigate and try to find ways that can lead them to their destination. The early Pacific Polynesians were the first to use the motion of the stars, weather, and the position of certain wildlife species or the size of waves to find the path from one island to another. The use of celestial navigation brought forward a new era were sailors tracked the movement of the stars to find paths to where they need to go. Further, in time the first useful invention to help was the magnetic compass. Evolving in time, the inventions of instruments such as the chronometer, the sextant, and several instruments that map the world around us came by.
