KEYBOARD : A keyboard is a human interface device which is represented as a layout of buttons. Each button, or key, can be used to either input a linguistic character to a computer, or to call upon a particular function of the computer. Traditional keyboards use spring-based buttons, though newer variations employ virtual keys, or even projected keyboards. Examples of types of keyboards include: Computer keyboard Kier Chorded keyboard LPFK
POINTINGDEVICES : A computer mouse A pointing device is any human interface device that allows a user to input spatial data to a computer. In the case of mice and touch screens, this is usually achieved by detecting movement across a physical surface. Analog devices, such as 3D mice, joysticks, or pointing sticks, function by reporting their angle of deflection. Movements of the pointing device are echoed on the screen by movements of the pointer, creating a simple, intuitive way to
HIGH-DEGREE of FREEDOMINPUT DEVICES : Some devices allow many continuous degrees of freedom as input. These can be used as pointing devices, but are generally used in ways that dont involve pointing to a location in space, such as the control of a camera angle while in 3D applications. These kinds of devices are typically used in CAVEs, where input that registers 6DOF is required.
COMPOSITE DEVICES(P-1) : Input devices, such as buttons and joysticks, can be combined on a single physical device that could be thought of as a composite device. Many gaming devices have controllers like this. Technically mice are composite devices, as they both track movement and provide buttons for clicking, but composite devices are generally considered to have more than two different forms of input.
COMPOSITE DEVICES(P-2) : Game controller A game controller is a device used with games or entertainment systems to provide input to a video game, typically to control an object or character in the game. A controller is usually connected to a game console or computer by means of a wire or cord, although wireless controllers are also widespread. Input devices that have been classified as game controllers include keyboards, mice, game pads, joysticks, etc. Special purpose devices, such as steering wheels for driving games and light guns for shooting games, are also game controllers. Devices such as mice and keyboards can be emulated with a game pad through the use of programs such as JoyToKey.
GAME PAD (or Joypad) A gamepad (also called joypad or control pad), is a type of game controller held in two hands, where the fingers (especially thumbs) are used to provide input. Gamepads generally feature a set of action buttons handled with the right thumb and a direction controller handled with the left. The direction controller has traditionally been a four- way digital cross (also named a joy pad, or alternatively a D-pad), but most modern controllers additionally (or as a substitute) feature an analog stick. Some common additions to the standard pad include shoulder buttons placed along the edges of the pad, centrally placed start, select, and mode buttons, and an internal motor to provide force feedback. Gamepads are the primary means of input on all modern video game consoles except for the Wii (though the Wii Remote can function alternately

IMAGING & VIDEO INPUTDEVICES(P-1): Video input devices are used to digitize images or video from the outside world into the computer. The information can be stored in a multitude of formats depending on the users requirement. digital camera Webcam Image scanner Fingerprint scanner Barcode reader 3D scanner Laser rangefinder
IMAGING & VIDEO INPUTDEVICES(P-2): Medical Imaging Computed tomography Magnetic resonance imaging Positron emission tomography Medical ultrasonography
AUDIO INPUT DEVICES: In the fashion of video devices, audio devices are used to either capture or create sound. In some cases, an audio output device can be used as an input device, in order to capture produced sound. Microphone MIDI keyboard or
