The Optical Mark Reader is a device that "reads" pencil marks on NCS compatible scan forms such as surveys or test answer forms. Tests and surveys completed on these forms are read in by the scanner, checked, and the results are saved to a file. This data file can be converted into an output file of several different formats, depending on which type of output you desire. In other terms it is a special scanning device that can read carefully placed pencil marks on specially designed documents.
 * I am Lisanne Guy and I will be presenting information on how these devices function and their uses: Optical Mark Reader (OMR), Mouse, Document Scanner, Voice Response Unit, Keyboard, Sensors and Pointing Devices. **
 * 1. **** __ Optical Mark Reader (OMR) __ **

Some uses of The Optical Mark Reader (OMR) are: Advantage: A quick and reliable way of inputting large volume of simple data
 * Used in forms, questionnaires, and answer-sheets.

Disadvantage: It can't be used for bulk text/numbers input. A mouse is a small device that a computer user pushes across a desk surface in order to point to a place on a display screen and to select one or more actions to take from that position.
 * 2. **** __ Mouse __ **

Some uses of the Mouse are: A document scanner is a machine that can copy a physical item and transfer an image of it to a computer. There are several types of these machines, including flatbed scanners and sheet-fed scanners. Using such a machine generally requires special software. In most cases, a document scanner is designed specifically to copy images or text on paper.
 * used to tell a computer what to do
 * Controls the coordinates of a cursor on your computer screen as you move it around on a pad.
 * Moving the cursor and choosing things on the screen.
 * 3. **** __ Document Scanner __ **

A document scanner can be a stand alone machine, or it may be part of a larger, multifunction device. These machines allow a document to be copied digitally, and an image of the document to be viewed on a computer. Some of the main parts of a scanner are the glass plate, the scan head, and the cover.

On a flatbed scanner, the cover is lifted and the document is placed faced down on the glass plate. Once the cover is closed and the machine is started, the scan head traces the document from one end to the other. The results are then sent from the document scanner to a computer. If a computer is not available, many of these machines have memories that can store the copied information.

Some uses of the Document Scanner are: The Voice Response Unit (VRU) is a computerized system that voices information for the individual calling in. The VRU is accessed by dialing a toll free number: 1-877-201-4263. The VRU welcomes the caller and asks the caller to enter his/her employee id number followed by his/her password. The password used on the VRU is the same password used with his/her RACF ID. The VRU requires all passwords to be 8 numbers long. The VRU does not recognize alpha or special characters.
 * To scan any documents that you want; regardless of where you are at.
 * To scan Images.
 * 4. **** __ Voice Response Unit __ **

Once the VRU verifies the individual calling in, the VRU will voice the number of outstanding hours of service reports that must be completed promptly. The VRU then instructs the caller to enter selection or press star (*) for the menu.

Some uses of the voice response unit are: The keyboard is the device that's used to input text into a computer.
 * Controls the operation of inbound phone call processing. This software application can be integrated into a complete call center operation.
 * Programmed to respond to the human's requests.
 * Accepts touch-phone keypad selection input from the caller and provides appropriate information in the form of voice answers or a connection to a "live" operator.
 * 5. **** __ Keyboard __ **

Some uses of the keyboard are:
 * Uses an arrangement of buttons or keys, to act as mechanical levers or electronic switches.
 * Used for direct (human) input into computers.
 * Used to type text and numbers into a word processor, text editor or other program.
 * Distinguishes each physical key from every other and reports all key presses to the controlling software.
 * Used for computer gaming, either with regular keyboards or by using keyboards with special gaming features, which can expedite frequently, used keystroke combinations.
 * Used to give commands to the operating system of a computer, such as Windows' Control-Alt-Delete combination, which brings up a task window or shuts down the machine. Keyboards are the only way to enter commands on a command-line interface.
 * 6. **** __ Sensors __ **

A device that detects or measures a physical property and records, indicates, or otherwise responds to it.

Some uses of Sensors are: A pointing device is an input interface (specifically a human interface device) that allows a user to input spatial (i.e., continuous and multi-dimensional) data to a computer. The pointing device is an element of the graphical user interface. It manipulates on screen objects to issue commands. Examples of pointing devices include the mouse, trackball, light pen, pen for graphic tablet, joystick, touch screen, wand, head mounted display, virtual reality glasses, and 3-D mouse.
 * Used in everyday objects such as touch-sensitive elevator buttons (tactile sensor) and lamps which dim or brighten by touching the base.
 * Responds to a physical stimulus (such as heat, light, sound, pressure, magnetism, or motion.)
 * It collects and measures data regarding some property of a phenomenon, object, or material. Typical sensors are cameras, radiometers and scanners, lasers, radio frequency receivers, radar systems, sonar, thermal devices, seismographs, magnetometers and gravimeters. The term "Remote Sensing" indicates that the measuring device is not physically in close proximity with the phenomenon being observed.
 * Detects a physical condition in the world.
 * 7. **** __ Pointing Devices __ **

Some uses of Pointing Devices are:
 * Is an external tool that is used to move objects around and also to select options from menus.
 * Another way to input information into the computer other than through the keyboard.
 * lets you double click on an icon to start a program application; and in the WINDOWS 95 operating system you can use the mouse to drag a file or document to the Recycling Bin to delete a file.
