What's in it?

New generation gaming experience

Beyond High-end visuals and makes game

play real by facilitating PHYSICALinvolvement

Offers reality experience

Player feels fully involved through physical

gestures & movements

Motion Capture

TechnologyProcess of recording movement andtranslating that movement onto a Digitalmodel.

Used in Military, Entertainment, sports,medical applications and for robotics.

Also in Film-making, It refers to recording

actions of human actors and using thatinformation to animate Digital charactermodels in 2D or 3D computer animation.

Motion Capture System

Where actor is performing and the motioncapture system can capture the props aswell as actors performance.

A computer processes the data anddisplays the movements of the actor,providing the desired camera positions.

Camera movements and stage driven byCamera Operator (having main roll inthat).

Having 200 or more cameras.


5/26

How to catch that Motion?

Here, Performer wears markers near eachjoint to identify the motion by the positions.

Markers can be : LED Marker, Magnetic orReflective or Combination of these all.

But, this is all terms of making digitalcharacters and with giving realityexperience.

You have enjoyed it in the movie AVTAR.

Devices in Motion Gaming

Motion sensing MEMS such as :

Accelerometer

Gyroscope

Magnetometer

This all are fully involved in any Motioncontrollers & Game pads.

The combination of MEMS and gamingsoftware can create an experience where theuser feels that he/she is a part of the game.

Motion Sensing MEMS

Accelerometer will detect linearacceleration. So it provide signal aboutmovements in all dimensions.

Gyroscope will detect angularacceleration and can provide accurateinformation about tilt, turn, rotation ormovements around an axis- even vertical

axis.

Magnetometer uses the earths magneticfield to a implement a compass ordirections into games.

Turn to Motion Gaming

ConsolesIdea of using accelerometer as the userinterface in mainstream gaming was takenby Nintendo Wii consoles controller.

Wiimote, which resembles a remote andhas a three-axis accelerometer andgyroscopes to detect motion.

Motion Gaming Market

The console gaming market is mainlycovered by

Microsoft Xbox Nintendo Wii

Sony PlayStation


11/26

Wii Remote

"Wiimote", is the primary controller forNintendos Wii console.

Motion sensing capability, which allowsthe user to interact with and manipulateitems on screen via gesture recognitionand pointing through the use ofaccelerometer and optical sensor

technology.


12/26

How Wii mote works?

Using Motion Sensing Technology

Mainly using Accelerometer is measuring

the strength and forces applied on WiiRemote

Uses Data converter, converts that analogforces into digital data

And for measuring direction moves, thereis a Sensor Bar

How..? I have a video for that.

PlayStation Move

Is a motion-sensing game controllerplatform for the PlayStation 3 (PS3) videogame console by Sony Computer

Entertainment (SCE).

PlayStation Move uses the PlayStation Eyecamera to track the wands position andinertial sensors in the wand to detect its

motion.


15/26

PlayStation Eye

Is a digital camera device, similar to awebcam, for the PlayStation 3.

The technology uses computer vision andgesture recognition to process imagestaken by the camera. This allows playersto interact with games using motion andcolour detection as well as sound through

its built-in microphone array.


16/26

PlayStation Eye

Is capable of capturing standard videowith frame rates of 60 hertz at a 640480pixel resolution, and 120 hertz at 320240

pixels, which is "four times the resolution"and "two times the frame-rate thanEyeToy.

Has "two times the sensitivity" of the

EyeToy


17/26

What is with Move?

Inertial sensors built into it, including anaccelerometer and a gyroscope that sensemotion on three axes.

They have added the illuminated ball onthe end of the controller and the cameraperipheral to help the system trackcontroller movement better.

The ball colour could be changed toidentify player 1 from player 2, 3, or 4.


18/26

How they work?

Sensors inside the controller, a three-axislinear accelerometer and a three-axisangular rate sensor (Gyroscope), are used

to track rotation as well as overall motion.

Magnetometer is also used for calibratingthe controller's orientation against theEarth's magnetic field to help correct

against cumulative error (drift) by theinertial sensors.

Inertial sensors can be used for deadreckoning in cases which the camera

tracking is insufficient.

Microsoft Kinect

Kinect (originally known by the codename Project Natal), is a "controller-freegaming and entertainment experience" by

Microsoft for the Xbox 360 video gameplatform, and may later be supported byPCs via Windows 8.

Provides full-body 3D motion capture,

gesture recognition, facial recognition andvoice recognition capabilities.

22/26

How it works?

The Kinect sensor's microphone arrayenables the Xbox 360 to conduct Activenoise control, allowing for things such as

headset-free party chat over Xbox Live.

The depth sensor consists of an infraredlaser projector combined with amonochrome CMOS sensor, and allows the

Kinect sensor to see in 3D under anyambient light conditions.
