Google has unveiled a prototype smart phone with "customized hardware and software" that enables it to make 3D maps of a user's surroundings. The device's sensors permit it make over 250,000 3D measurements every second and update its position in real-time. Google said possible applications may include indoor mapping, helping the visually-impaired navigate untried indoor places unassisted and gaming.
It has offered 200 prototypes to developers keen to make apps for it. Google supposed its Advanced Technology and Projects unit developed the phone as part of a project called Project Tango with help from researchers at various institutions. We are physical beings that live in a 3D world. Yet, our mobile plans assume that physical world ends at the boundaries of the screen.
