Hands-Free GPS Device for the Blind Could Make You a SuperheroThe Navigation aid for the Blind headset is a GPS device, which not only works through speech recognition, but also uses obstacle detection technology that alerts the blind of any sleeping bums or other obstructions he could trip over as he is being guided to his destination. In 2003, we reported on a GPS navigation device that led the visually impaired to their impending doom due to an "inaccuracy" of the system. Although this new GPS device is not as cuddly as a guide dog, it is made up of one earpiece and microphone, which would allow the blind a certain anonymity, kind of like Daredevil, in that he would no longer need a cane or furry pet, which would leave both of his hands free ... to fight crime, perhaps?
