=My Device (APOLV)= The device of use is the PS2 video game controller.

//(adopted by Sam Meneses)//

Purpose
The purpose of this device is to be able to control what you do while using your playstation 2. You control everything that goes on dealing with your playstation 2. You use the controller for many different purposes. You may be a guy running. Using the joysticks to move him while using one of the 4 action buttons to make him do specific actions, or use it to scroll through the menus of the game.

Energy
The energy the PS2 controller uses is electrical energy. When you press a button it sends a signal through the wire in the controller to the game system.

Controls
The playstation 2 controller consists of 19 different controls. There are 4 main action buttons, which are located on the right side of the controller in a diamond position. The 4 buttons are the triangle located on the top, circle on the left the X button on the bottom, and square on the right. There is also a directional pad on the left. You can choose to move up down left or right. You can also hold more then one of them at a time and your character will obey your command. There is a start button usually meant for pausing the game located in the middle, along with a select button that doesn't have a big pupose other then in sport video games. An analog button is also in the middle used for switching between using the analog sticks and directional pad. There are 2 joysticks located near the bottom of the controller so you can have a more 360 degree control. You can also click those in and they may serve as action buttons. On the top left and top right of the controller there are four more buttons used as secondary action buttons. Not every button has the same pupose for each game either. Different games have different controls and different settings so be heads up.

The PS2 controller is a controller made completely of plastic. From all of the buttons in the controller to the shell of the controller. The PS2 controller also has many wires in itself. There are also sensors and magnets to sense whether you're pressing buttons or making a movement on the joystick.

Science
The science in the PS2 controller is electicity and motion. Electricity is used when the controller sends a signal through to the console. There is also motion used because the person has to move his fingers and make other motions to send signals to his PS2.

Design
A typical controller has a typical "winged shape" as described by many different websites. The 4 action buttons are located on the right of the controller. The directional pad is located on the left of the controller. The secondary action buttons are located on top of the controller. The 2 360 degree joysticks are located at the bottom. Finally, the start, select, and analog control are located in the middle of the controller.

Evolution
The PS2 controller has evolved from a few different types of controllers. The first one being the Atari joystick. It had one stick in the middle to go up down left and right. Next came the nintendo controllers which was really small and had two buttons with a the directional pad. Then came they playstation 1 controller. The PS2 evolved just a bit from that.

Competitors
There is the Xbox and Xbox 360 controller. These are made for the Xbox or Xbox 360 device. This console is very similar to the playstation. They all run on the same puspose, except the Xbox and Xbox 360 have a different button, color, and shape scheme from the playstation 2 controller.

Partners
The Playstation 2 controller is hooked up to the main console. This console has 2 other wires connecting to it. A power wire to get power for the console, and AV cables. You hook the cables into the back of your TV so you can see the visual and hear the audio. You can also say the TV is a partner to the PS2.

Siblings
The playstation 2 controller is the second generation of 3 playstation generations. The First playstation was built much similar except came in a gray color and didn't have analog sticks. The controller was for the original playstation. The playstation 3 controller has an extremely similar look and feel as a playstation 2 controller. The major differences are the playstation 3 controller will usually come wireless, meaning it doesn't have to plug directly into the console, and it also has a headset port where you can plug a headset into your controller and interact with other people while being plugged into the internet.
