This is from an interview I found on the web. The guy actually took a ultra-sonic sensor and fed the signals down on to his nervous system.
Kevin Warwick is the world’s first cyborg. The English scientist says that it’s time for us to overcome our human “limitations”. In the future and thanks to chip in our brains we will be able to use more than our 5 senses as the implants will stretch our ways of communicating with people and objects. Without any doubt, Warwick is a brave, charismatic borderline-scientist, but he has also risen a lot of criticism. In an interview he reveals why he thinks that humans will become a subspecies in a cyborg world.
