3. OBJECTIVE
 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.

4. INTRODUCTION
 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.

5. CORE TECHNOLOGIES
 Motion Tracking
 Depth Perception
 Area Learning

6. Motion Tracking
 Motion Tracking means that a Tango device can track its own
movement and orientation through 3D space.
 Walk around with a device and move it forward, backward, up, or down,
or tilt it in any direction, and it can tell you where it is and which way it's
facing.
 It's similar to how a mouse works, but instead of moving around on a
flat surface, the world is your mousepad.

7. Depth Perception
 With depth perception, your device can understand the shape of
your surroundings.
 This lets you create "augmented reality," where virtual objects not
only appear to be a part of your actual environment, they can also
interact with that environment.
 One example: you create a virtual character who jumps onto a real-
world table top.

8. Area learning
 Human beings learn to recognize where they are in an environment by
noticing the features around them: a doorway, a staircase, the way to the
nearest restroom. Tango gives your mobile device the same ability. With
Motion Tracking alone, the device "sees" the visual features of the area it is
moving through but doesn’t "remember" them.
 With Area Learning turned on, the device not only remembers what it sees,
it can also save and recall that information. When you enter a previously
saved area, the device uses a process called localization to recognize
where you are in the area. This feature opens up a wide range of creative
applications. The device also uses Area Learning to improve the accuracy of
Motion Tracking.

9. HOW CAMERA WORKS ?
 There are three cameras that capture a 120-degree wide-angle field
of view from the front.
 A depth sensor to calculate the depth of the objects in the
surroundings.
 A fish eye camera which captures 180 degrees wide angle field
view.

12. TANGO’S SENSOR
 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."

13. 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).

15. Things Project Tango can do .
 Directions
 Shopping
 Emergency Response
 Augmented Reality Gaming
 Modeling Objects

16. DIRECTIONS
 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.

17. EMERGENCY
RESPONSE To help emergency response workers such as firefighters find their
way through buildings by projecting the blueprints onto the screen.
AUGMENTED REALITY
GAMING
 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
gaming experience.

21. CONCLUSION
 It makes life simple.
 Takes gaming to the next level.
 This Technology can be awesome for differently abled People.
