The whiz kids at Nike have one-upped the competition once again. Their next product concept entitled "Nike Hindsight" is a pair of futuristic sunglasses with super-peripheral vision. Nike is targeting bicyclists who would benefit from earlier detection of vehicles approaching from the side as well as reducing the amount of head rotation to check behind, but this concept can potentially have a multitude of consumer applications.
The shades use fresnel lenses on both sides of the glasses, which allows the user to detect motion beyond the normal 180º field of view. I could try to explain this in more detail if I was technically capable, but all that matters is if it actually works!
Product design that actually enhances human senses. What will they think of next?
