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 Page 190
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.
BMCA Hardware: • Pharmacy Scanner • Multiple computers • Keyboard • Mouse • Portable scanner
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
Are All Tags The Same? Variations: • Memory • Size (16 bits - 512 Kbytes +) • Read-Only, Read/Write or WORM • Type: EEProm, Antifuse, FeRam • Arbitration (Anti-collision) • Ability to read/write one or many tags at a time • Frequency • 125KHz - 5.8 GHz • Physical Dimensions • Thumbnail to Brick sizes • Price ($0.50 to $250)
Portal Applications Bill of Lading Material Tracking
HazMat Smart Label • Low power > long range • 1024 bit memory • Read/write/lock on 8 bits • Advanced protocol • Efficient multi-id Lock data permanently • 12 ms/8 byte read 25ms/byte write • Group select Broadcast write • 40 tags/second Anti-collision

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 • Structure Resistive 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.
