INTRODUCTION
Kinect motion technology uses a sensor device
called kinect,a 3D scanner which interprets 3D
scene information from a continuously projected
infrared structured light.
Is used for:
–Xbox 360 console
–Windows PCs
–Robots

ContdKinect was developed by microsoft .
Enables users to control and interact with the
application/game.
–Without the need to touch a game controller .
–Through a natural user interface .
–Using gestures and spoken commands .

3-D depth sensors
Three-dimensional sensors tracks the body within
the play space.
RGB camera
An RGB (640 × 480) pixels
helps identify and takes in-game pictures and
videos.
Multiple microphones
An array of microphones along the bottom, front
edge of the Kinect sensor are used for speech
recognition and chat.
Motorized tilt
A mechanical drive in the base of the Kinect
sensor automatically tilts the sensor head up and
down when needed.

Light Coding With Kinect:
Structured light is a form of active
triangulation.
In structured light,a known pattern
is projected onto the scene, and the
depth is calculated on the basis of the
triangulation between a known reference
pattern and observed reflected pattern.

CASE STUDY
The TurtleBot is a customizable mobile robotic
platform that rides on an iRobot Create platform
.
The TurtleBot uses the Kinect to see the world
in 3D and for detecting and tracking people.

DISADVANTAGES
Sensitive to external infrared source
(sunlight).
Cannot detect crystalline or highly reflective
objects.

RESULT ANALYSIS
Detection and tracking of one or two people
moving in the field of view of the sensor, using
the tracking of parts of the skeleton.
Capture audio with noise and echo
cancellation.
Speech Recognition.

CONCLUSION
This technique aims to provide an
application that uses gestures to interact with
virtual objects in an Augmented Reality
application.
Providing a way for using the gesture-based
interactions to manage operations in a virtual
walkthrough environment is a promising
approach.
