Project Tango is a project by Google that aims to give mobile devices a 3D understanding of space using advanced sensors and computer vision. The Tango prototype is an Android device that tracks its own 3D motion and creates a 3D model of the surrounding environment in real-time. It uses motion tracking, depth perception, and area learning technologies. Potential applications include improved indoor navigation, more efficient shopping, emergency response, augmented reality gaming, and 3D modeling of objects.

7. 
 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.
 Project Tango strives to give mobile devices a human-
like understanding of space and motion through
advanced sensors and computer vision.
OBJECTIVE

8.  A device which tracks the 3D motion of the device, and
creates a 3D model of the environment around it.
 Launched on 20th February 2014.
 by Google’s Advanced Technology and Projects group
(ATAP)
 A mobile device that shares our sense of space and
movement, that understands and perceives the world
the same way we do.

 Depth Perception
 Area Learning
CORE TECHNOLOGIES

10. 
 Motion tracking allows a
device to understand
position and orientation
using Project Tango's
custom sensors. This
gives you real-time
information about the 3D
motion of a device.
Motion Tracking

11. 
 Project Tango devices are equipped with integrated 3D sensors
that measure the distance from a device to objects in the real
world. Current devices are designed to work best indoors at
moderate distances (0.5 to 4 meters). It may not be ideal for
close range object scanning.
 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.
Depth Perception

12. 

13. 
 Using area learning, a 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 Description File (ADF) to
use again later.
 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.

 A mobile device that can see how we see
 NVIDIA Tegra K1 Processor
 Motion Tracking Camera
 4MP 2µm Pixel Camera
 Integrated Depth Sensing

17. 
 There are three cameras that capture a 120-degree wide-
angle field of view from the front.
 An even wider 180 degree span from the back.
 A 4-MP color camera sensor can also be used for
snapping regular pics.
HOW CAMERA WORKS ?

18. 

19. 
 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."
TANGO’S SENSOR

20. 
The phone emits pulses of infrared light and records how it is reflected
back allowing it to build a detailed depth map of the surrounding
space.
3D camera-
It is a device that captures the 3D structure of a scene. Most cameras
are 2D, meaning they are a projection of the scene onto the camera's
imaging plane; any depth information is lost. In contrast, a 3D camera
also captures the depth dimension (in addition to the standard 2D
data).

Things Project Tango can
do .

25. 
 When you need directions inside a building or structure
that current mapping solutions just don’t provide.
 Shopping - who just like to get in and out as quickly as
possible. Having an indoor map of the store in your
hand could make shopping trips more efficient by
leading you directly to the shelf you want.
DIRECTIONS

26. 
 To help emergency response workers such as firefighters
find their way through buildings by projecting the
blueprints onto the screen.
 It has the potential to provide valuable information in
situations where knowing the exact layout of a room can
be a matter of life or death.
EMERGENCY RESPONSE

27. 
 It could combine the room-mapping with
augmented reality. “Imagine competing against a
friend for control over territories in your own home
with your own miniature army.
 Mapping in-game textures onto your real walls
through the smartphone would arguably produce
the best game of Cops and Robbers in history.

 This Technology can be awesome for differently abled People.
