Google is an American multinational technology company specializing in Internet-
related services and products. These include online advertising technologies, search,
cloud computing, and software.
Google also have many some research and development sub-companies like Google
ATAP and Google X. These companies work on developing future techs.
Project Tango is a smartphone and tablet project by
Google's Advanced Technology and Projects group
(ATAP), formerly a division of Motorola. The "Project
Tango" prototype is an Android smartphone-like device
which tracks the 3D motion of the device, and creates a
3D model of the environment around it without
using GPS or other external signals.
Project Tango strives to give mobile devices a human-
like understanding of space and motion through
advanced sensors and computer vision.

Advanced Technology and Projects (ATAP)
• Project Tango was introduced by Google initially in early 2013, they described
this as a Simultaneous Localization and Mapping (SLAM) system capable of
operating in real-time on a phone. Google’s ATAP teamed up with a number of
organizations to create Project Tango from this description.
Project Tango was developed by a team led by
computer scientist Johnny Lee, a core
contributor to Microsoft's Kinect.

and movement, that understands and perceives
the world the same way we do.

smartphone before you went furniture shopping?
What if you never again found yourself lost in a
new building? What if you could search for a
product and see where the exact shelf is located
in a store?

IR PROJECTOR :
The IR projector projects a pattern of IR light which
falls on objects around it like a sea of dots. We can't
see the dots because the light is projected in the
Infra-Red color range
RGB-IR CAMERA :
Red Green Blue -Infrared Camera
RGB-IR camera single sensor that captures high-resolution images and video as well as IR
information, enabling depth analysis.
FISHEYE CAMERA :
The fisheye lens enables a 180º FOV used to track objects, while the sensor balances resolution
and frames per second to record black and white images for motion tracking.
• Project Tango devices combine the camera,
gyroscope and accelerometer to estimate
six degrees of freedom motion tracking,
providing developers the ability to track 3D
motion of a device while simultaneously
creating a map of the environment.
• The phone emits pulses of infrared light
from the IR projector and records how it is
reflected back allowing it to build a detailed
depth map of the surrounding space.
Myriad 1 vision processor platform.
The sensors allow the device to make "over a quarter million
3D measurements every second, updating its position and
orientation in real time, combining that data into a single 3D
model of the space around you.“
Myriad 1 low-power computer-vision processor, process the
data and feed it to apps through a set of APIs.
Project Tango’s core functionality is measuring
movement through space and understanding
the area moved through.
Google API’s provide the position and
orientation of the user’s device in full six
degrees of freedom.
Using area learning, Project Tango device can
remember the visual features of the area it is moving
through and recognize when it sees those features
again. These features can be saved in an Area
Project Tango devices can use visual cues to help
recognize the world around them. They can self-
correct errors in motion tracking and relocalize in
areas they've seen before
Project Tango devices are equipped with
integrated 3D sensors that measure the distance
from a device to objects in the real world.
Because the technology relies on viewing infrared
light using the device's camera, there are some
situations where accurate depth perception is
difficult. Areas lit with light sources high in IR like
sunlight or incandescent bulbs, or objects that do
not reflect IR light cannot be scanned well.
By combining depth perception with motion
tracking, you can also measure distances between
points in an area that aren't in the same frame.
When you need directions inside a building or structure that current mapping
solutions just don’t provide.

• Google Tango With NASA
ATAP over at Google announced that they will be partnering with NASA
to build autonomous robots. Using the technology developed for
Project Tango, the Spheres robot will be able to do tasks the astronaut
previously had to do themselves.
• Google Glass
Developers are proposing to connect technology in project
tango with google glass.
