What if directions to a new location didn't stop at the street address?

What if you could capture the dimensions of your home simply by walking around with your phone

before you went furniture shopping?

What if you could search for a

product and see where the exact shelf is located in a

super-store?

CONTENTS

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

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.

INTRODUCTION

Motion Tracking Depth Perception Area Learning

CORE TECHNOLOGIES

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

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

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.

Area learning

TECHNICAL SPECIFICATION

A mobile device that can see how we see

NVIDIA Tegra K1 Processor  Motion Tracking Camera  4MP 2µm Pixel Camera  Integrated Depth Sensing

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 ?

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

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).

DEVELOPMENT PHASE

Directions Shopping Emergency Response Augmented Reality Gaming Modeling Objects

Things Project Tango can do .

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

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

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.

AUGMENTED REALITY GAMING

Modeling Objects

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

People.
