Write different types of input devices and their functions with Figure.

What are the different types of input devices which you are using in daily life? Give these types of input devices and their introduction with a sketch diagram.

Introduction of post about the different types of input devices with some figure topic covers following listed below

Introduction of input devices such as; Scanner, Web camera, Mouse, Keyboard, Microphone, Headphone, Sensing remote, MICR, BCR, OMR, Biometric scanner, Light pen, Joystick, Game controller, Infra Shooting gun, Bluetooth receiver, Touch screen with sketch diagram.

Scanner 

The scanner input device is used to capture a hard copy of documents such as photos, document or file, certificate, a part of a book etc. The scanner is a single device but it is attached with mostly printers because this type of combination increases space for other devices and objects on the table and where you are working at that place.

Web camera

Web camera input devices are used to capture your real time position as per frame rate according to the quality of the web camera. The web camera is attached with a mini stand over the monitor. It is suitable to attach the web camera over the monitor because the output of the real time capture is displayed on the monitor of the second person with a small part of our face and position.

Mouse

Mouse input device is a pointing device which is used to point any object in the GUI (Graphical User Interface) form of the operating system where such objects as file, folder, drives etc. The mouse is used with their pad, the pad is made up of leather, rexine or nylon and rubber.

Keyboard

Keyboard input device is used for typing work and operates the operating system of a computer by typing a command. It has so many keys with different functionality of work to perform on the operating system. Keyboard has its own PCB circuit which decides to give the input instructions in a proper form and to control the speed of the input signal.

Microphone 

Microphone input devices are used to take input signals of the audio category to the computer and the operating system can understand the signal received by the transmitter receiver of the microphone. Some microphones are too small in size and very easy to use. 

Headphone

Headphone input device is used to give signal of audio similar to the microphone but there is an additional feature given in the headphone is speaker attached with microphone stick. The headphone wears on your head and the microphone sticks over your mouth for a clear voice to hear.

Sensing remote 

Sensing remote is a type of input device that is used to control television functions and their operating system. The remote has two batteries in a type of pencil battery that is used to power up the remote which is able to send input signals generated through the remote circuit and sent by the remote sensor in front of the remote.

MICR

Magnetic Ink Character Recognition is an input device which is used to read the ink character which includes magnet property. In this device there is a special character reader which senses the magnetic ink printed on the card, mostly some types of cheques.

BCR

The bar code reader is an input device which is used to read the printed on the object. These objects are available in the market and for business purposes such as products in retail shops and shopping malls. These input devices penetrate the beam from the face of the BCR device by pressing a button on the bar code. The bar code looks like a group of lines in a specific space.

 

OMR

Optical mark reader is a machine that takes input from an OMR sheet. These sheets are mostly used for educational purposes which are filled by students for entrance exams and competitive exams. The OMR sheet is filled mostly by the ball ink pen, especially black pen to fill the area of 'abcd' in the sheet; this area is read by the OMR input devices and sent to the computer database.

Biometric scanner

Biometric scanner scans your finger lines to detect your identification. When you  touch a finger which you can store the finger data in the machine it asks to store the data of your finger. After you store finger data in your database in the machine, you can only touch to verify your identification with one touch of your finger from the machine.

Light pen 

It is a pen-like structure connected with the CPU and performed on the monitor screen. It operates the operating system which is only in the form of graphical user interface (GUI). You can use it as a mouse pointing device. Mostly the light pen is used only in the CRT monitors but in some cases there are so many types of monitor LCD and TFTs can work with light pens.

Joystick

Joystick is an input device mostly used in the game, especially the racing game. The racing needs acceleration and moving fast objects such as cars, buses and bikes etc. It has a stick to move the object in the game and also has some buttons for performing actions in the game through the player.

Game controller

Game controllers are used to play every type such as action games, racing games and story games. It has so many buttons on the controller which is divided into two parts: left and right. Left parts have an action performed through the object and right side buttons perform movements of the object in the game. These game controllers are mostly used in gaming platforms which are attached with monitors or smart TVs.

Infra Shooting gun

Infra Shooting gun is a game controller gun which is used to shoot an object in the game by a beam penetrated from the gun. It is a specific tool for the game to perform a different action such as shoot only. It is used only in the game shooting type. For example, a mosquito shooter game.

Bluetooth receiver

The Bluetooth receiver is an input device which receives the output signal generated through the Bluetooth device sender and finally sends it to the computer. In headphone also uses one side calling headphone which includes Bluetooth in calling device.

Touch screen

Touch screen is a both types of devices; input and output. When you touch the screen it gives the input instruction to the operating system of any type of device which you are using a computer and smart mobile phone. After the process of input instruction it gives output on the screen in your device. 

Trackball   

Trackball is a pointing device which is used to point an object and select the object where the object is known as files, folders, drives, icons etc. a trackball is similar to the mouse input device which is also known as a pointing device. On the trackball there is a one ball to roll in the device which is used to move the pointer on the monitor displays on the screen, the pointer is known as a tool which is used to select an object, open menu, delete object etc.
