This technological revolution is starting to profoundly change not only how we interact with the world around us, but is allowing us to see, hear, smell, taste and even touch things we never imagined possible before.An artificial intelligence revolution is super-charging sensing technology, promising us eyes with laser precision, ears that can distinguish every sound in a mile's radius and noses than can sniff out the early signs of forest fires before the first flame forms.Evolutionary biologist and broadcaster Professor Ben Garrod is off to meet some of these sensory innovators and technological pioneers - the programmers, robotics engineers and neuroscientists, who are turning our world upside down and inside out.In episode four - we’ll explore touch and what role does it plays for our nearest living relatives.
