My brother sent me a link to a really cool invention that enhances your senses with virtual whiskers.
Ever wanted some cat's whiskers or insect antennae? Probably not, but check out this head-mounted haptic device developed by researchers at the University of Tokyo in Japan. It lets a wearer "feel" their surroundings from a distance, roughly as if they had several long whiskers sticking out of the head. At least, that's what the researchers say.
A series of infrared sensors positioned around the device act as invisible whisker or antenna sensors. When these detect an object, a small motor vibrates on the appropriate side of the wearer's head to alert them.
A brilliantly simple idea that will find a myriad of applications.
