The Xbox 360 is Microsoft's video game console introduced in 2005. It uses a custom IBM multi-core PowerPC processor and ATI graphics card. It has 512MB of RAM and supports up to four wireless controllers. The Xbox 360 introduced Xbox Live for online multiplayer gaming. Later, Kinect was added, using infrared and video cameras to track a user's body movements and voice to control games without a controller. The Xbox One features improvements like an 8-core AMD processor, 8GB of RAM, and enhanced graphics capabilities over the Xbox 360.

2. INTRODUCTION
 Microsoft's video game console, the Xbox 360, has sold over 80
million units worldwide since its introduction in 2005.
 Microsoft rebuilt the Xbox from the ground up. From the name
to the look to hardware and features.
 Xbox 360 is a total media center that allows users to play,
network, rip, stream and download all types of media,
including high-definition movies, music, digital pictures and
game content.

3. INSIDER
 Custom IBM Power PC-based CPU with three 3.2 GHz cores
 Custom ATI graphics processor with 10 MB embedded DRAM
 512 MB 700 MHz GDDR3 RAM
 Detachable and upgradeable hard drive
 12x dual-layer DVD-ROM
 Support for up to four wireless game controllers
 Three USB 2.0 ports
 Two memory unit slots

4. The heart of 360- The CPU
 Microsoft has outfitted the 360 with a 165-million transistor, multi-
core processor running three 3.2-GHz PowerPC cores.
 Multi-core processors offer a combination of tremendous
computing capabilities and efficient power consumption.
 Each core is capable of processing two threads simultaneously.
 With a multi-core processor, the system is powerful enough to pull
off the computational demands needed for an amazing gaming
experience without even breaking a sweat.

5. GPU: Graphics Processor Unit
 Custom-built 500-MHz ATI Graphics Processor card with 10 MB of
embedded DRAM.
 It is built on unified shader architecture.
 Shaders are computer programs that determine the final look of what
you see on the screen when you're looking at computer animation.
 Pixel Shaders
 Vertex Shaders
 Both shader types share the same pipelines.
 48 billion shader operations per second.

6. Xbox 360 Controller
 Wireless controllers
 Support up to four wireless controllers at one time.
 Microsoft created a proprietary technology to deal with
some of the latency and bandwidth issues that can be a
problem for some wireless controllers.
 Some wireless headsets will also work with Xbox.

7. Other 360 features
 Input/output
 Online
 TV Connections
 Audio
 Removable Hard Drive and Storage
 The Disc Drive
 Cooling
 Other Accessories

8. Xbox LIVE
 Xbox LIVE is an online subscription service that allows Xbox
gamers to play video games together and download
additional game content using the internet.
 Xbox LIVE has created a huge online community of gamers
challenging one another worldwide.
 Xbox LIVE on the 360 is divided into two services: Xbox LIVE
Silver and Xbox LIVE Gold.

9. Virtual Reality
 Virtual reality is the creation of a highly interactive computer based
multimedia environment in which the user becomes a participant with the
computer in what is known as a “synthetic environment.”
 Three-dimensional images that appear to be life-sized from the
perspective of the user
 The ability to track a user's motions, particularly his head and eye
movements, and correspondingly adjust the images on the user's display
to reflect the change in perspective

11. KINECT
 Kinect has revolutionized gaming, in that you are able to use
your entire body as the controller.
 3 major functions
• movement tracking
• speech recognition
• motorized tilt of the sensor itself

12. KINECT: 3D Sensing technology
 A company based In Israel known as PrimeSense developed
the 3D sensing technology.
 3 main parts that make it work
• Infrared laser projector
• Infrared camera
• RGB colored camera

13. IR sensing
 IR depth sensor is a monochrome complimentary metal-oxide-semiconductor
(CMOS) camera.
 IR camera used in the Kinect is VGA resolution (640x480) cam refreshing at a
rate of 30Hz.
 Each camera pixel has a photodiode connected to it, which receives the IR
light beams being bounced off objects in the room.
 The voltage produced by the photodiode is directly
proportional to the distance the object.

14. Role of software
 Using statistics, probability, and hours of testing different
natural human movements the programmers
developed software to track the movements of 20
main joints on a human body.
 This is how Kinect can differentiate a player.
 Kinect has the capabilities of tracking up to six
different players at a time.

15. Color camera
 The depth sensing and the color camera work together to
develop an accurate digital image of how your face
looks.
 8- bit color camera, also VGA resolution, detects and
stores the skin tone of the person.
 Storing these images of your face and skin tone color is
how the Kinect can recognize you when you step in front
of the projected IR beams.
 Another added feature of the color camera is it takes
videos or snapshots .

16. Xbox one improvements
 Xbox One is larger than the Xbox 360.
 The Xbox 360 has a PowerPC-based CPU - it's a triple-core 3.2GHz
processor. The Xbox One has an eight-core processor based on the AMD
Jaguar chip series.
 The Xbox 360 has 512MB of RAM, the Xbox One has 8GB of RAM.
 Xbox One version looks far more detailed than Xbox 360.
 Xbox 360 obviously has a much, much stronger games library than the
newborn Xbox One.
 The Xbox One predictably, costs a lot more.
