This document discusses and classifies other input devices. It describes pens, touch screens, and game controllers as devices for the hand. It also discusses touch screens, bar code readers, image scanners, optical character recognition, and microphones as audiovisual input devices. Pens allow for handwriting input on devices like PDAs and tablets. Touch screens use sensors to allow finger input on screens. Game controllers include joysticks and game pads for computer game input. Bar code readers identify bar codes to input product information into computers. Image scanners and OCR convert images and characters into electronic formats. Microphones input audio, such as for video conferencing.

2. Overview
1. Introduction to Other Intput Device.
2. Classification or Types of Other Intput
devices.
3. Description of the Other Inutput Devices.

3. Introduction
Other input device is just like input device . Other input
devices are important parts of some special purpose computer .
Tapping a handheld computer’s screen with a pen is a much faster
way to input commands than typing on a miniature keyboard.
CPU
(process)
Input Output
A Simple Diagram shows the computer system that how
a input is taken and given the output after data processing.

4. Types of Other Input devices
Other Input devices can be classified in two major types:
1. Device For The Hand
2. Audiovisual Input Devices
Device For The Hand Audiovisual Input Devices

5. Description of the Other Input
Devices
PENS
Data collector & Called it stylus
Deciphers people handwriting with 100% reliability.
Pen is popular for PDAs and tablet PCs task .
Common use is for inputting signatures

6. Touch Screens
Allowing the user fingertip on the computer screen.
Use sensors on the screen’s surface.
Works well in ATM ,restaurants, supermarket & etc.

7. Game ControllersConsidered an input device because a computer game
is a program.
Two type : game pads &
Joystick.
Using a Joysticks rather than a mouse.
Game pad is a small & flat device which use as
joysticks.

?

9. Bar Code Readers
Most widely used input device.
Commonly found in supermarket & department
store.
A light-sensitive detector identifies the bar code
image & identify the product.
Identifying the bar code, it converts the bar patterns
into numeric digits code the computer can
understand

10. Image Scanners and Optical
Character Recognation(OCR)Convert any printed image into
electronic format.
By using Scanner and software
to organize or manipulate the
electronic image.
To translate bitmaps into text,
the OCR tries to match the
character with its own
assumptions.
OCR software is extremely
complex and not always 100%
reliable.

11. Audiovisual Input Devices
Microphones
Input devices to record speech.
Useful for audio & videoconferencing.
For sound input need microphone
and sound card.
Sound card translate audio signals
from microphone.
Use microphone to record voice and
create files on disk.
