MojoKid writes Google's Project Tango Android tablet offers a new way to interact with the world through the use of 3D mapping and real-time depth sensing. Combined with custom software and hardware sensors, Project Tango devices are capable of performing over a quarter million 3D measurements per second to create a 3D model of the world we see. There are endless possibilities as Google notes. "What if you could capture the dimensions of your home simply by walking around with your phone before you went furniture shopping? What if the visually-impaired could navigate unassisted in unfamiliar indoor places? And there are obvious big advantages in gaming applications for positioning, augmented reality, etc. Google was offering a first-hand experience with virtual reality gaming using Project Tango at GTC in San Jose today, and the results are pretty impressive. The first demo involved Zombie Gunship Reality, which allows you to take aim at killer zombies from the relative safety of the air. Using an NVIDIA Tegra K1-powered Project Tango dev tablet, you're able to aim your weapon by moving the tablet around in front of you, which provides for a more immersive experience than just tapping/swiping away on the screen alone to move. Google also demoed how a Project Tango device could be used to create a 3D capture of a room or even an entire building, giving users a way to navigate through unfamiliar surroundings without the need for Wi-Fi or GPS hardware.
