    • HARDWARE & SOFTWARE OVERVIEW
    • CAPTURING INFORMATION WITH INPUT DEVICES
      • If you need to capture information and/or interact with the computer, use input devices
      • INPUT DEVICES are the tools you use to capture information or commands at the
      • The key is to use the right input device that will capture information at its point of origin .
        • S is the goal when working with TPS input: at the
    •  
      • Keyboards provide a means for the user to input info and commands directly into the computer system (by typing).
      • The mouse inputs data or commands when you click on icons or buttons.
      • Touch-tone input device: data or commands are input using a telephone keypad.
      • Voice recognition system: input data or commands via a person speaking. Captures sound
      • Bar code reader: reads information in the form of vertical bars
      • Magnetic ink character recognition is used to read the pre-printed information at the bottom of checks and deposit slips.
      • Touch screens: users input info by touching the screen (touch-sensitive area)
      • Optical mark recognition: detects the presence or absence of a mark in a pre-determined spot, such as on a scantron or test form.
      • Optical character recognition reads actual numbers or letters (which have been standardized)
      • Image scanners can be used to take something on paper and convert it into a computer-usable form.
      • Digital cameras can be used to input an image/picture of an object, which then can be manipulated by the computer.
      • Trackballs function much like a mouse does, but instead of moving the actual device (like with a mouse), you control the cursor by moving the ball.
      • Virtual reality input devices are used to capture and convey movement.
      • Pointing Sticks are used control cursor movements (most often seen in laptop computers)
    • Radio Frequency Identification (RFID)
      • Uses a in a tag or label to transmit information back and forth between an object and a receiving device.
        • Can be used to inventory, inventory and product .
        • Pay at toll road plazas.
