Kinect for Xbox 360, Launch of full body Motion Sensor
Through this article I'm going to write about another new gadjet which is launched by Microsoft. Its a special peripheral device designed for xbox 360 and launched in last Thursday, 4th of November 2010. Its named as "kinect" and it has amazing technology that developers used to detect human motions in three dimensions(3D). It can capture multiple users' full body motion in the same time and analyze it and attach the video to xbox video game characters. This gadget enables people to play video games through the use of body movements.It uses a 3D camera and motion recognision software that lets people play video games through the use of natural body movements and voice commands instead of the popular hand held controlers.
It consists of three main systems to recognize human interfaces.
- RGB camera to identify 2D motions
- Dept sensor and analyze motion to 3D
- Wide range microphone array to identify voices of each person.
RGB camera is a high resolution camera that can capture each user's 2D(2 dimention) motion. This system commonly used to facial recognition and identify facial expressions. The interesting system is depth sensor that they used to get 3D motion full body motion. They used two sensors in parallel to get the real 3D video that similar to human eye. This sensor contains an infrared projector combined with a
monochrome CMOS sensor, which is allow the Kinect sensor to see in 3D under
any ambient light conditions. It has adjustable sensing range. Through the software, it can automatically calibrate the sensor on
gameplay and also the player's physical environment, such as the presence of
furniture. Wide range microphone array used to catch the voice of each person with out low noise disturbance for the software. Gadget runs by its own software that converts the body movements into a signal as same as that old hand controllers produced to main xbox processing unit.
This device based on software
technology developed internally by Microsoft and also a range camera technology
by Israeli developer called PrimeSense, which interprets 3D scene information
from a continuously-projected infrared pattern. PrimeSense developed the method and core software that Microsoft's
forthcoming camera controller uses to read human bodies and gestures,
and had it running on a prototype unit live in the booth. This software licenced to microsoft and PrimeSense only provides the raw tech behind the visual gesture system. Kinect is capable of simultaneously tracking up to six people, including two active players for motion analysis with a feature extraction of 20 joints per player. Full body gaming will be enjoyable for every one. No controlers needed while you are the controller. Kinect official website introduced this as Controller-free gaming generation. So if you have to kick, then kick. If you have to jump, then jump. You already know how to play. All you have to do now is to get off the couch.
