INPUT & OUTPUT
By Deepak Singhal
WHAT IS INPUT?
Any data or instructions used by a computer
Input devices Hardware
Keyboards Pointing devices Scanners Other devices
Translates data into a form that the system unit can process
Page 180
WHAT IS OUTPUT? Processed data or information Types of output
Text Graphics Audio & video
Output devices Monitors Printers Other Devices

ROBOT SENSORS
Why do Robots Need Sensors? Makes robots “interesting” Gives the robot capability to goal-seek Protection & Self-Preservation Allows interaction with environment
WHAT SENSORS ARE OUT THERE? Photoelectric (Visible) Infrared (light) Ultrasonic (sound) Color Sensors GPS (location)
BAR-CODING
Why use barcodes? As far back as the 1960s, barcodes were used in
industrial work environments. Some of the early implementations of barcodes included the ability identify rail road cars.
In the early 1970s, common barcodes started appearing on grocery shelves. To automate the process of identifying grocery items, UPC barcodes were placed on products.
Today, barcodes are just about everywhere and are used for identification in almost all types of business
READING BARCODES
One of the most common tools for reading barcodes is the hand held barcode scanner. All of the barcode scanner recommended and sold by ID Automation have built-in decoders that can read several different bar code types.
Most of the scanner sold by ID Automation receive their power from the PC keyboard or USB port so no external power supply is required. When a barcode is scanned, the data is sent to the PC as if it was typed using a keyboard.
BASIC STEPS
BMCA HARDWARE: Pharmacy Scanner Multiple computers Keyboard Mouse Portable scanner
INFORMATION SYSTEMS:System Elements Definitions BMCA Examples
Input Data and information entered into a computer system
Scanned orders, entered orders, scanned barcodes
Process Action of transforming input into output
Pharmacy and nurses verifying orders in the system throughout the process
Output Changes that exit a system and that can activate or modify processing
After scan, software verifies that the medication is correct according to the 5 rights of administration so the medication can be given
Feedback Information from the system that is used to make modifications in the input, processing actions, or outputs
Pharmacy message option, medication error forms
Control Regulates: input via checks, process by completing the operations & detecting errors, and output by ensuring conformity
Pharmacy allergy checks, scanning alerts when wrong medication scanned, wrong time, etc.
WHAT IS RFID?
RFID is an ADC technology that uses radio-frequency waves to transfer data between a reader and a movable item to identify, categorize, track...
RFID is fast, reliable, and does not require physical sight or contact between reader/scanner and the tagged item
RFID OPERATIONS
ARE ALL TAGS THE SAME?

HOW DOES A TOUCH SCREEN WORK?
A basic touch screen has three main components:1 Touch sensor;2 Controller; 3 Software driver.The touch screen is an input device, so it needs to be combined with a display and a PC or other device to make a complete touch input system.
TOUCH SCREEN
StructureResistive touch screens consist of a glass or acrylic panel that is coated with electrically conductive and resistive layers made with indium tin oxide (ITO) .The thin layers are separated by invisible spacers.
