Mulit-Function Devices

In the Wellesley college libraries, there are multi-function devices (MFDs) that are both copiers and printers. This blog post is a detailed analysis of the MFDs. I worked on this project with Amy Feldman, so we have similar data/information, although our wording is different.

Analysis of the MFDs

The analysis was created using the 7 stages proposed by Donald Norman in The Design of Everyday Things
  • Forming the goal
    • Print: The goal is to print a document from a library computer on an MFD.
    • Copy: The goal is to copy a physical document using an MFD.
  • Forming the intention
    • Print: The person intends to print a document.
    • Copy: The person intends to copy a document.
  • Specifying an action
    • Print:
      • Pressing the print button on the computer
      • Approving the print command
      • Walking over to the MFD
      • Logging into the MFD
        • Press username
        • Type username
        • Press enter
        • Press password
        • Type password
        • Press log in
        • Press ok
      • Approving the print command
      • Pressing the start button
    • Copy:
      • Walking over to the MFD
      • Logging into the MFD
        • Press username
        • Type username
        • Press enter
        • Press password
        • Type password
        • Press log in
        • Press ok
      • Lifting the top off of the copier section
      • Placing the document on the glass in the correct position
      • Closing the copier section
      • Pressing the start button
      • Remove document
      • Press access
      • Press log off
      • Lift top off of copier section
      • Remove original
  • Executing the action
    • Print: Execute the specified actions.
    • Copy: Execute the specified actions.
  • Perceiving the state of the world
    • Print: Seeing paper(s) come out with words and/or images.
    • Copy: Seeing paper(s) come out with words and/or images.
  • Interpreting the state of the world
    • Print: Noting that the paper(s) that came out are connected with the previous actions performed
    • Copy: Noting that the paper(s) that came out are connected with the previous actions performed
  • Evaluating the outcome
    • Print: Comparing the paper(s) that came out with the original electronic document.
    • Copy: Comparing the paper(s) that came out with the original paper document.

    How easily can one:

    • Determine the function of the device?
      • Relatively easily if one is at all acquainted with printers or copiers.
    • Tell what actions are possible?
      • Not particularly easily, as the device is ambiguously covered in various trays, drawers, and buttons.
    • Determine mapping from intention to physical movement?
      • With difficulty, as the device’s screen and buttons do not afford clear understanding of the actions necessary to print or copy documents.
    • Perform the action?
      • Print: With relative difficulty if one is not acquainted with the device and the systems added by Wellesley College.
      • Copy: With relative difficulty if one is not acquainted with the device and the systems added by Wellesley College.
    • Tell what state the system is in?
      • With relative difficulty, as the process takes place completely within the MFD. The MFD does provide feedback in the form of certain sounds, but the user would have to be very, very well acquainted with the MFD in order to determine which sound goes with which state.
    • Determine mapping from system state to interpretation?
      • With difficulty, as the device does not provide good feedback regarding the system state itself, making interpretation difficult.
    • Tell if the system is in the desired state?
      • Somewhat easily, as paper(s) with the desired words and images only come out if the system is in the desired state. However, there is a time lag between achieving of the desired state (by pressing the “Start” button) and hearing the whirring noises that accompany the device’s document production.
    Based on this analysis,

    What is effective about the MFDs?
    The MFDs provide clear feedback about whether or not an action was executed properly, but only after the action is complete. When one perceives the state of the world, interprets the state of the world, and evaluates the outcome, it is immediately obvious whether or not the action was successful.

    What is problematic about the MFDs?
    There are many steps that one must specify and execute in order to print or copy a document. Also, under "perceiving the state of the world," one is not able to sense if an action was executed properly until the paper does or does not come out of the MFD. This is poor feedback and thus problematic.

    Needs Assessment
    Observe (approximately 10-20 minutes of observation)
    • One girl pulled off one of the trays while trying to print
    • People would sometimes ask others how to use the MFDs
    • Some people found the task quite simple and completed it by apparent rote
    • One person got help from others

    Ask
    Methodology: Brief, individual interviews, because we feel that is the most straightforward way to gain personalized perspectives.

    Questions:
    1. What year are you in?
    2. Have you used an MFD?
    3. How often do you use the MFDs per week?
    4. When did you first try to use an MFD?
    5. How would you describe that experience?
    6. How would you rate the ease of use of the MFDs the first time you used one? (scale of 1 to 10, 1 being brushing your teeth, 10 being climbing Mount Everest)
    7. How about now?
    8. How did you first learn how to use an MFD?
    9. If you could change one thing about the MFDs, what would it be?

     *Our sample size is very small, so this data might not be representative of the entire Wellesley College community.

    Try
    Julie (printing): It took me a minute to figure out how to release my document from the queue, even with the instructions. I was not at all sure that I was doing the right things.

    Amy (copying): It took me a while to figure out what the results would be — what size paper, what orientation, and so on. The default “auto” settings are a nice idea, but they don’t tell you what they’re planning, which seems like poor feedback.
