The Internet giant has unveiled a prototype phone that brings human sight to mobile technology. The Smartphone uses cameras and motion sensors to give users a 3D map of their surroundings. The sensors can make more than 250,000 three-dimensional measurements a second, updating the device’s position in real time. Gaming enthusiasts will no doubt be jumping up and down at the prospect of augmented reality games on cell phones, but 3D phones could also be revolutionary in helping the blind navigate unfamiliar locations. With Google Glass and now this, the company is showing real vision.
