Abstract

Motion Gaming goes beyond high-end visuals and makes game play real by

facilitating physical involvement in a game. Motion sensing provides a new

generation gaming experience that actively responds to the players physical

movements. The aim of the gaming application is to produce an immersive,

augmented reality experience through the integration of the virtual with the real

world.

Some Important Terms: Accelerometer, Gyroscope and Magnetometer.

i. Introduction

Motion gaming technology uses

motion sensing devices combined with

the advanced software technology to

translate physical gestures through

controllers, joysticks and game pads

into movements which are seen on-

screen, at the same time. Motion

gaming technology relies on

movement of the users body and

limbs as inputs to interact with the

game as opposed to use of buttons

either through a keyboard, joystick or

game controller. It offers a realistic

experience, which adds to the thrill of

playing games. Motion gaming started

with the Nintendo Wii consoles

controller, the Wiimote.

ii. Motion Capture Technology

Motion capture, motion tracking, or

mocap are terms used to describe the

process of recording movement and

translating that movement onto adigital model. It is used in military,

entertainment, sports, medical

applications and for validation of

computer vision and robotics. In

filmmaking it refers to recording

actions of human actors, and using

that information to animate digital

character models in 2D or 3Dcomputer animation. When it includes

face, fingers and captures subtle

expressions, it is often referred to as

performance capture.

In motion capture sessions,

movements of one or more actors are

sampled many times per second,

although with most techniques (recent

developments from Weta use images

for 2D motion capture and project into

3D) motion capture records only the

movements of the actor, not his/her

visual appearance. This animation data

is mapped to a 3D model so that the

model performs the same actions as

the actor. This is comparable to the


5/15

5

older technique of rotoscope, such as

the 1978 The Lord of the Rings animated

film where the visual appearance of

the motion of an actor was filmed,

then the film used as a guide for the

frame by frame motion of a hand-

drawn animated character.

Camera movements can also be

motion captured so that a virtual

camera in the scene will pan, tilt, or

dolly around the stage driven by a

camera operator, while the actor isperforming and the motion capture

system can capture the camera and

props as well as the actor's

performance. This allows the

computer generated characters, images

and sets, to have the same perspective

as the video images from the camera.

A computer processes the data anddisplays the movements of the actor,

providing the desired camera

positions in terms of objects in the set.

Motion tracking or motion capture

started as a photogrammetric analysis

tool in biomechanics research in the

1970s and 1980s, and expanded into

education, training, sports and

recently computer animation for

television, cinema and video games as

the technology matured. A performer

wears markers near each joint to

identify the motion by the positions or

angles between the markers. Acoustic,

inertial, LED, magnetic or reflective

markers, or combinations of any of

these, are tracked, optimally at least

two times the frequency rate of the

desired motion, to sub millimetre

positions.

Now, relating this capture to the

gaming.

iii. Motion Sensing MEMS

The devices used in Motion Gaming

include Motion Sensing MEMS such as

accelerometer, gyroscope and

magnetometer.

An accelerometer can detect linear

acceleration so it can provide a signalabout movement in all three

dimensions.

A gyroscope can detect angular

acceleration and can provide accurate

information about tilt, turn, rotation or

movement around an axiseven the

vertical axis.

A magnetometer uses the earths

magnetic field to implement a compass

or directions into games.

The combination of MEMS andgaming software can create an

experience where the user feels that he

or she is a part of the game. For e.g.

Tennis video games, which were

earlier played by clicking mouse

buttons can be played just as you

would on an actual tennis court.

MEMS can accurately map themovement of a players wrist and send

the signal to the gaming software to

display the same on screen.

iv. Motion Gaming Market

The motion gaming market isprimarily divided into two segments

namely console and mobile gaming.

The console gaming market is

dominated by the Sony PlayStation,

Microsoft Xbox and Nintendo Wii.

These gaming consoles, and the

software for the same, are much in

demand in India and can be found inalmost every electronic shop.

The recent development of motion

gaming on the mobile has brought this

technology within the reach of the

masses. The sensors used for motion

gaming are also being used to

augment existing and upcoming

applications for mobile phones. e.g.

Movement from portrait/landscape, to

advanced navigation (augmented-

reality) or image stabilization. Mobile

devices can act as a remote, joystick,

tennis racket or steering to implement

games, which are triggered by hand

movements.

Indias gaming market of $70 million is

growing significantly at 35% year-on-

year. The introduction of 3G services is

expected to give a boost to the gaming

market in the country. The latestFederation of Indian Chambers of

Commerce and Industry report pegs

the Indian media and entertainment

industry at Rs. 587 billion ($12 billion)

and gaming is estimated to be the

fastest growing sector in this industry,

during the next five years.

v. Mobile Motion Gaming

Motion gaming has become one of the

key differentiating factors in mobile

phones. The emergence of local

players has led to an intensification of

competition and brought down prices.As a result, companies rely on

differentiating factors such as motion

sensing in order to maintain profit

margins.

Most of the latest high-end mobile

phones such as the iPhone 4, Samsung

Galaxy S etc. support accelerometer-

based motion gaming. Game

developers are also developing games

for these platforms taking advantage

of the high processing power on these

devices. The Samsung Galaxy S has a

1GHz processor. Some common games

using this technology are car racing

games such as Need for Speed: Shift.

The iPhone 4 has an integrated motion

sensor, which can be used to run third-

party applications, games and even

motion sensing ads. Sega Super

Monkey Ball has been one of the most

successful iPhone games in this

category.

However, there are also some failures

like the Sony Ericsson F305, which

looks like the Wii controller and comes

equipped with an accelerometer but

fails miserably because its almostimpossible to follow what youre

doing. If you swing the phone to bowl,

you cant see where the ball is going.

LG Cookie, amongst the cheapest

touchscreen phones around, also offers

a decent motion gaming experience.

Moreover, Nokia is gearing up to enter

this segment with an announcementthat most devices coming later this

year will include an accelerometer.

Currently, the Nokia N79, N82, N85,

N95, N95, N96 and the 6210 Navigator

are equipped with the technology.

vi. Console Motion Gaming

A console manufacturer is a company

that manufactures and distributes

video game consoles. It is also known

as a first-party video game publisher.

Some of the most recognized console

manufacturers include:

Microsoft newest major player in the

market, releasing the Xbox and Xbox

360 consoles.

Nintendo historically the bestknown console manufacturer; also the

longest running company in the

market, and long-time dominant

market leader of the handheld console

market.

Sony Computer Entertainment

found worldwide success with its first

console, the Sony PlayStation.

Here, Primary motion controller for

this gaming consoles.

Wii Remote

The Wii Remote , sometimes

unofficially nicknamed "Wiimote", is

the primary controller for Nintendo's

Wii console. A main feature of the Wii

Remote is its motion sensing

capability, which allows the user to

interact with and manipulate items on

screen via gesture recognition and

pointing through the use of

accelerometer and optical sensor

technology. Another feature is its

expandability through the use of

attachments. The attachment bundled

with the Wii console is the Nunchuk,

which complements the Wii Remote

by providing functions similar to those

in gamepad controllers. Some other

attachments include the Wii Classic

Controller, Wii Zapper, and the Wii

Wheel, originally used for Mario Kart.

The Wii Remote assumes a one-

handed remote control-based design

instead of the traditional gamepad

controllers of previous gaming

consoles. This was done to make

motion sensitivity more intuitive, as a

remote design is fitted perfectly for

pointing, and in part to help the

console appeal to a broader audience

that includes non-gamers. The body of

the Wii Remote measures 148 mm

(5.83 in) long, 36.2 mm (1.43 in) wide,

and 30.8 mm (1.21 in) thick. The Wii

Remote model number is RVL-003, a

reference to the project codename

"Revolution".

The controller communicates

wirelessly with the console via short-

range Bluetooth radio, with which it is

possible to operate up to four

controllers as far as 10 meters (approx.

30 feet) away from the console.

However, to utilize pointer

functionality, the Wii Remote must be

used within five meters (approx.

16 feet) of the Sensor Bar.

Sensor Bar

The controller's symmetrical design

allows it to be used in either hand. The

Wii Remote can also be turned

horizontally and used like a

Famicom/NES controller, or in somecases (like Excite Truck, Sonic and the

Secret Rings, Mario Kart Wii, and Sonic

and Sega All-Stars Racing) a steering

wheel. It is also possible to play a

single-player game with a Wii Remote

in each hand, as in the Shooting Range

game contained in Wii Play.

The controller was made slightly

longer, and a speaker was added to the

face beneath the centre row of buttons.

The "B" button became more curved

resembling a trigger. The "Start" and

"Select" buttons were changed to plus

"+" and minus "", and the "b" and "a"

buttons were changed to 1 and 2 to

differentiate them from the "A" and "B"

buttons. Also, the symbol on the

"Home" button was changed from a

blue dot to a shape resembling a

home/house, the shape of the power

button was made circular rather than

rectangular, and the blue LEDs

indicating player number are now

labelled using small Braille-like raised

dots instead of Arabic numerals, with

"1" being "", "2" being "", "3" being

"", and "4" being "". Also, the

expansion port was redesigned, with

expansion plugs featuring a smaller

Snap-On design.

PlayStation Move

PlayStation Move (This Changes

Everything) is a motion-sensing game

controller platform for the PlayStation

3 (PS3) video game console by Sony

Computer Entertainment (SCE). Based

on a handheld motion controller

wand, PlayStation Move uses thePlayStation Eye camera to track the

wand's position, and inertial sensors in

the wand to detect its motion.

First revealed on June 2, 2009,

PlayStation Move launched in

mainland Europe and most Asian

markets on 15 September 2010, in

Australasia on 16 September 2010, in

North America and the UK on 17

September 2010, in Japan on 21

October 2010. Hardware available at

launch included the main PlayStation

Move motion controller, a

supplementary PlayStation Move

navigation controller, and an optional

PlayStation Move charging station.

The primary component of PlayStation

Move, the PlayStation Move motion

controller is a wand controller which

allows the user to interact with the

PlayStation 3 through motion and

position in front of the PlayStation Eye

webcam.

They have added the illuminated ball

on the end of the controller and the

camera peripheral to help the system

track controller movement better

The PlayStation Eye is a digital

camera device, similar to a webcam,

for the PlayStation 3. The technology

uses computer vision and gesture

recognition to process images taken by

the camera. This allows players to

interact with games using motion and

colour detection as well as sound

through its built-in microphone array.

It is the successor to the EyeToy for the

PlayStation 2, which was released in

2003.

The PlayStation Eye is capable of

capturing standard video with frame

rates of 60 hertz at a 640480 pixel

resolution, and 120 hertz at 320240

pixels, which is "four times the

resolution" and "two times the frame-rate" of the EyeToy, according to Sony.

The PlayStation Eye also has "two

times the sensitivity" of the EyeToy,

with Sony collaborating with sensor

chip partner Omni Vision

Technologies on a sensor chip design

using larger sensor pixels, allowing for

more effective low-light operation.

Now, again back to Move, The

PlayStation Move motion controller

features an orb at the head which can

glow in any of a full range of colours

using RGB light-emitting diodes

(LEDs). Based on the colours in the

user environment captured by the

PlayStation Eye webcam, the system

dynamically selects an orb colour that

can be distinguished from the rest of

the scene. The coloured light serves as

an active marker, the position of which

can be tracked along the image plane

by the PlayStation Eye.

A pair of inertial sensors inside the

controller, a three-axis linear

accelerometer and a three-axis angular

rate sensor, are used to track rotation

as well as overall motion. An internal

magnetometer is also used forcalibrating the controller's orientation

against the Earth's magnetic field to

help correct against cumulative error

(drift) by the inertial sensors. The

inertial sensors can be used for dead

reckoning in cases which the camera

tracking is insufficient, such as when

the controller is obscured behind theplayer's back.

The controller face features a large

ovoid primary button (Move), small

action buttons ( , , , ), and a

regular-sized PS button, arranged in a

similar configuration as on the Blu-ray

Disc Remote Control. On the left and

right side of the controller is a Select

and Start button, respectively. On the

underside is an analog trigger (T). On

the tail end of the controller are the

wrist strap, USB port, and extension

port.

The motion controller features

vibration-based haptic technology. In

addition to providing a tracking

reference, the controller's orb light can

be used to provide visual feedback,

simulating aesthetic effects such as the

muzzle flash of a gun, or the paint on abrush.

Microsoft Kinect

Kinect for Xbox 360, or simply Kinect

(originally known by the code name

Project Natal), is a "controller-free

gaming and entertainment experience"

by Microsoft for the Xbox 360 video

game platform, and may later be

supported by PCs via Windows 8.

Based around a webcam-style add-on

peripheral for the Xbox 360 console, it

enables users to control and interact

with the Xbox 360 without the need to

touch a game controller , through a

natural user interface using gestures,

spoken commands, or presented

objects and images. The project is

aimed at broadening the Xbox 360's

audience beyond its typical gamer

base.

Kinect was launched in North America

on November 4, 2010, in Europe on

November 10, 2010, in Australia, NewZealand and Singapore on November

18, 2010 and in Japan on November 20,

2010. Purchase options for the sensor

peripheral include a bundle with the

game Kinect Adventures and console

bundles with either a 4 GB or 250 GB

Xbox 360 console and Kinect

Adventures.

Kinect is based on software technology

developed internally by Rare, a

subsidiary of Microsoft Game Studios

owned by Microsoft and range camera

technology by Israeli developer

PrimeSense, which interprets 3D scene

information from a continuously-

projected infrared structured light.

The Kinect sensor is a horizontal bar

connected to a small base with a

motorized pivot, and is designed to be

positioned lengthwise above or below

the video display. The device features

an "RGB camera, depth sensor and

multi-array microphone running

proprietary software", which provides

full-body 3D motion capture, facial

recognition and voice recognition

capabilities. Voice recognition

capabilities will be available in Japan,

the United Kingdom, Canada and the

United States at launch, but have been

postponed until spring 2011 in

mainland Europe. The Kinect sensor's

microphone array enables the Xbox

360 to conduct acoustic source

localization and ambient noise

suppression, allowing for things such


13/15

13

as headset-free party chat over Xbox

Live.

The depth sensor consists of an

infrared laser projector combined witha monochrome CMOS sensor, and

allows the Kinect sensor to see in 3D

under any ambient light conditions.

The sensing range of the depth sensor

is adjustable, with the Kinect software

capable of automatically calibrating

the sensor based on gameplay and the

player's physical environment, such asthe presence of furniture.

According to information supplied to

retailers, the 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.

Through reverse engineering efforts, ithas been determined that the Kinect

sensor outputs video at a frame rate of

30 Hz, with the RGB video stream at 8-

bit VGA resolution (640 480 pixels)

with a Bayer colour filter, and the

monochrome video stream used for

depth sensing at 11-bit VGA resolution

(640 480 pixels with 2,048 levels ofsensitivity). The Kinect sensor has a

practical ranging limit of 1.2 3.5

metres (3.911 feet) distance when

used with the Xbox software.
