1.INTRODUCTION OF WII

The WII is a video game console made by Nintendo. It first came out on

November 19, 2006 in North America. It plays video games made for the WII

and the Nintendo GameCube. As a seventh-generation console, the WII

primarily competes with Microsoft's Xbox 360 & play -station 3.Nintendo, the

company that made the WII, says they want to focus more on new ways to

play games. The WII uses a controller, called the WII Remote , that is very

different from the controllers of other video game consoles. It can be held with just one hand, and uses technology that senses the player's movements.

By making the WII, Nintendo says they are trying to change the way

video games are looked at and played. The WII was made for all people of any

age or interest. By making it easier to play, Nintendo thinks that they can get

people who do not normally play games to start playing. As of October 2010,

the WII leads the generation over the PlayStation 3 and Xbox 360 in

worldwide sales, and in December 2009 broke the record for best-selling

console in a single month in the United States.

WII already has a strong lineup of games in production, with many more

to follow. Familiar characters like Mario and Link will make appearances, as

well as new franchises. Instead of just focusing on better graphics like their

rivals, Nintendo are focused on delivering an improved, fun playing

experience with better interactivity. The WII will also retail at a much lower

price than the other consoles. All in all the WII is an exciting breakthrough in

gaming.

2.MOTION SENSING

This is the one type of technology which is used in the WII. Motion can be

detected by: sound, reflection of transmitted energy & vibration. motion

detectors, have sensors that detect movement & send a signal to a sound device

that produces an alarm or switch on an image recording device. There are

motion detectors has cameras connected to a computer which stores and

manages captured images. A simple calculation for motion detection by a fixed

camera compares the current image with a reference image and simply counts

the number of different pixels. Since images will naturally differ to reference

image it knows something is changed.

A forum, "2010 Motion Sensing Technology," was organized by

Digitimes and sponsored by Epson on September 16, 2010 to discuss the

growing market for motion sensors and their new applications. Industry

experts and academic researchers were invited to present their views of the

market and technology trends at the forum, which took place at Grand Victoria

Hotel in Taipei.

There are many types of motion sensors available in the market, mostly

used to detect changes in external conditions. In terms of detection technology

and applications, they can be divided into inertia sensors, optical sensors,

environmental sensors, pressure sensors, and so forth. Up until recently,

motion sensors have been used mainly in automotive and specialized industrial

applications. However, new applications and broader market opportunities for

motion sensors have emerged since 2006 when the devices were first utilized

in the Nintendo WII console.

3.REMOTE

REMOTE is a part of the WII gaming system. It act a important role in the

WII console system.

8/3/2019 Wii Report


The WII Remote sometimes unofficially nicknamed "WII mote", 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 viagesture 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 Nunchu, which complements the WII Remote by providing

functions similar to those in gamepad controllers.

Nintendo announced a free accessory for the WII Remote the WII

Remote Jacket, on October 1, 2007. The removable silicone sleeve wraps

around the WII Remote to provide users a better grip and cushioning. The

cushioning intends to keep the WII Remote protected in case it is accidentally

dropped or thrown. Nintendo started shipping consoles, separately-packaged

controllers, and the controller included in the game WII Play with the jacket on

October 15, 2007.

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 ft) away from the console.

4.CONSOLE

It is the main processing unit of the WII gaming system. It is

based on MOTION SENSING technology.

The WII Console is a cutting-edge piece of technology in the video

game world.

8/3/2019 Wii Report


The console, originally named the “Revolution”, was r enamed the

“WII” because the WII sounds like “we” which makes it a multiplayer oriented

system. The system has four wireless controllers with gyroscope technology.

Gyroscope technology is a fancy name for motion sensor technology. There

has never been a video game console that has used motion-sensor technology.

This system enables the user to actually act out the moves in the game. For

example, in a sword-fighting game the user swings the controller as if they

were swinging the sword.

The whole purpose behind the WII was to initiate the race for new

technology in the video game industry, as well as create a system in which the

individuals are actually playing the game, rather than sitting in a couch moving

only their thumbs. The main feature of the WII console is the WII remote, and

the wireless internet. . The WII console itself cannot only play single as well

as double layered WII discs, but also Game cube discs. The larger part of this

report will be written on the WII controller, as well as the sensor bar.

The controller itself has accelerometers, which according to which way

the controller is swung, activates capacitors on either side of an electric field,

which pick up the signal from the sensor bar. The WII console refers to the box

that plays the discs. The console has several different parts to it. There is an

area where the player can load either a double-layered disc, (a disc with more

information on it), and also a single layered disc. An interesting feature to the

WII is the fact that it can also play Game cube games. Essentially the system is

double compatible; it can play both WII games and Game cube games. The

system itself also has four Game cube controller ports, for multiplayer action

as well as two memory card slots for Game cube.

5.ACCELEROMETER

An accelerometer is a device that measures proper acceleration, the

acceleration experienced relative to freefall.

Single- and multi-axis models are available to detect magnitude and direction

of the acceleration as a vector quantity, and can be used to sense orientation,

acceleration, vibration shock, and falling. Micro machined accelerometers are

increasingly present in portable electronic devices and video game controllers,

to detect the position of the device or provide for game input.

An accelerometer measures proper acceleration, which is the

acceleration it experiences relative to freefall and is the acceleration felt by

people and objects.

8/3/2019 Wii Report


Put another way, at any point in space time the equivalence

principle guarantees the existence of a local inertial frame, and an

accelerometer measures the acceleration relative to that frame. Such

accelerations are popularly measured in terms of g-force.

An accelerometer at rest relative to the Earth's surface will indicate

approximately 1 g upwards, because any point on the Earth's surface is

accelerating upwards relative to the local inertial frame (the frame of a freely

falling object near the surface). To obtain the acceleration due to motion with

respect to the Earth, this "gravity offset" must be subtracted and corrections for

effects caused by the Earth's rotation relative to the inertial frame. The reason

for the appearance of a gravitational offset is Einstein's equivalence

principle, which states that the effects of gravity on an object are

indistinguishable from acceleration.

When held fixed in a gravitational field by, for example, applying a

ground reaction force or an equivalent upward thrust, the reference frame for

an accelerometer (its own casing) accelerates upwards with respect to a free-

falling reference frame. The effects of this acceleration are indistinguishable

from any other acceleration experienced by the instrument, so that an

accelerometer cannot detect the difference between sitting in a rocket on the

launch pad, and being in the same rocket in deep space while it uses its engines

to accelerate at 1 g. For similar reasons, an accelerometer will read zero during

any type of free fall.

This includes use in a coasting spaceship in deep space far from any

mass, a spaceship orbiting the Earth, an airplane in a parabolic "zero-g" arc, or

any free-fall in vacuum. Another example is free-fall at a sufficiently high

altitude that atmospheric effects can be neglected.

6.SENSOR BAR

The WII Sensor bar, which is technically an array of infrared LED.The relative

movement of the infrared LED will be used for cursor position update. The

infrared camera is generally used in the SENSOR BAR. The WII sensor bar is

a device for the Nintendo WII. It detects the motions of the WII

Remote and Nunchuk via Bluetooth technology. The WII's sensor bar coupled

with the WII Remote allows the game to sense acceleration and to determine

where the player is pointing.

The WII Remote senses light projected from the bar, contrary to what a

standard light gun can perform. Five LED lights are positioned on both sides

of the sensor bar, with a total of ten in all. Because of the viewing angle of the

WII Remote, being too far away from the sensor bar will result in a disruption

and possibly disconnection.
