Examples of Input Devices
Here are some examples of input devices:
keyboard is a common example of an input device because it allows users to input text, numbers, and other characters by pressing keys. It sends signals to the computer which translates the key presses into data that the computer can understand.
A mouse is a handheld input device. It controls the cursor and allows the selection of items on a display screen. As the mouse moves, it sends signals about its movement that the computer translates into on-screen cursor movement to select or interact with elements.
3. Light Pen
A light pen is also an input device. It utilizes a light-sensitive detector to select objects on a computer display screen. When positioned over a desired area, the light pen detects the screen location and sends signals to the computer to act as mouse clicks or selections in that area.
A scanner is an input device because it captures text, images, or objects and converts the information into a digital format that can be used by the computer. The scanner uses light sensors to collect visual information and transform it into models or images on the computer.
A joystick is an input gaming device. It consists of a handheld stick that conveys the physical motions of the player into signals. Which the computer translates into movements or actions in a video game or simulation.
A microphone converts sound waves from a user’s voice or other audio signals into analog or digital signals that the computer receives as input and can interpret for various purposes.
A touchscreen is an input device covering a display screen that allows the user to directly interact with elements on the screen by pressing on them with a finger or stylus, sending signals to the computer to register the selections.
A trackball is an input device consisting of a ball mounted in a base that can be spun in any direction to control the movement of items on a computer display screen. It allows cursor movement and selection similar to a mouse.
A webcam is a video camera and audio input device. It captures images, video, and sound and sends them to a computer in real-time. It allows the user to communicate visually and audibly with others, hold video conferences, and more.
10. Magnetic Ink Reader
A magnetic ink reader reads text or numerical information printed with a special ink containing particles of magnetic material. It converts data from paper checks, bank slips, etc into digital form the computer can process.
11. Barcode Reader
A barcode reader is an optical input scanner. It reads information encoded in the widths, spacings, and depths of printed bars on a label or package and converts it into data the computer system can interpret and process, like product information.
12. OCR – Optical Character Recognition
OCR or optical character recognition software uses an input scanner device. It optically captures and recognizes text characters in images or documents, then converts them into editable computer text that retains all fonts, formats, layouts, and other aspects of the original file.
13. Graphic Tablet
A graphic tablet is an input device enabling precise, pen-like control for drawing, writing, or selecting areas on a computer screen. As the pen moves across the tablet surface, it sends precise coordinates to represent the motions in painting or design programs.
The digitizer input device combines a touch-sensitive tablet with a specialized electronic pen so operators can easily capture and input freehand writing, drawings, or sketches directly into digital document files or images the computer can process. They allow more natural computer inputs than a keyboard and mouse alone.
A touchpad is a flat, touch-sensitive square input device. It allows users to control the computer by moving fingers over its surface instead of needing a mouse or stylus. Multi-touch models recognize multiple finger inputs like pinches or swipes.
Biometric input refers to advanced computer input technologies. It automatically recognizes individuals based on unique biological attributes like fingerprints, voices, retinas, facial patterns, pulses, or brain waves, allowing secure logins.
17. Optical Mark Recognition
Optical mark recognition is a type of input device where an optical scanner detects user responses in predefined areas like bubbles or boxes on paper survey forms, tests, and ballots and converts selected marks into digital data for assessments.
18. Audio Input Device
Audio input devices such as microphones and voice receivers. It allows users to speak to them. It captures the vocal vibrations which computers can translate into input commands to control programs or transcribe into text documents.
Gamepads are handheld gaming input devices with buttons, joysticks, and directional pads tailored for gameplay, and interactions to send signals enabling precise control for complex moves in computer video games.
Headphones allow both audio output for the listener and audio input via an integrated microphone to capture the user’s voice. As a multifunctional peripheral, headphones enable voice communication, voice commands, dictation, or speech recognition.
