An anonymous reader writes: Ph.D. candidates Aisen Caro Chacin and Takeshi Ozu at Japan's Tsukuba University have created a haptic sonar glove that allows wearers to "feel" objects that are out of reach underwater. "IrukaTact" uses sonar to detect items from a distance, and applies increasing pressure to the fingertips as the user moves closer. The glove has been packaged as a DIY kit that could potentially be used to search for victims or sunken objects, as well as for specific hazards, such as sinkholes.
