                                                         After several initial mockups, our team decided it
                                                         wasn’t a good design for a user to select an answer
Product Goals:                                           choice using the “tap selection method” . The “tap
                                                         selection method” is summarized below:
♦   Information presented is readable and not
    cluttered                                            ♦   If the answer choice is not highlighted, tap the
                                                             desired answer choice once; the answer choice

                                                         ♦   If the answer choice is highlighted, tap the
                                                             answer choice again; the answer choice is

           unselected and no longer highlighted                (Figure 2) .
        Several issues arose in our design using a “tap se-
        lection method” . First, if the answer to a question
        is several sentences in length, one dilemma we
        faced was, “how will they see the full answer (plus
        the visual image)?” If the user tapped a question
        is several sentences in length, one dilemma we
        faced was, “how will they see the full answer (plus
        the visual image)?” If the user tapped the answer
        choice, the answer choice would be selected . So
        we needed to figure out a new design for the user
        to see the entire answer length .
        When a user first views the answer choices, they’ll
        notice that each answer is horizontally oval-
        shaped . They know exactly the spatial area to
        tap when selecting their answer choice(s) . Thus,
        our team agreed to eliminate the “tap selection
        method”, and use the “one tap” to enable the user
        to see the entire answer (Initial Prototype, slides
        5-7) .                                                 Figure 2: Fantasy Football drag and drop roster feature

        As a result of eliminating the “tap selection meth-    To make it more intuitive and reinforce that the
        od” from our design, another issue that arose was,     drag and drop feature mode is on, an icon was
        “how can the user select their answer choice(s)        added to indicate that the answer is maneuver-
        quickly and without tapping?”                          able .
        One idea we decided to experiment with was
        dragging and dropping your answer choice(s) .
        We designed it where the user can drag and drop
        their answer selections to the black transpar-
        ent area at the bottom of the iPod Touch screen
        (Figure 3) . This concept is not a new multi-touch
        feature on the iPod Touch . The “drag and drop
        method” is an interaction currently used when
        you want to personalize the buttons you want to
        display the most . Tap ‘Edit’ and drag the button
        to the location you want . For example, in the iPod
        Touch guided tour, if you listen to audio books
        and want to get to them faster, drag audio books
        over songs to replace songs . In addition, we found

   Usability Results
      ANSWER KEY: 1. Test Participant 1 response          2. Test Participant 2 Response



   Task 1.1 Questions
   Is it clear and intuitive where to tap to view the entire answer choices?
   1. Yes, I just tapped on the right arrow .
   2. Yes


   Did you have trouble finding your way back to your answer choices from the entire answer description screen?
   1. No, it was clear to press the back arrow .
   2. No, but its annoying for me to keep going back and forth every time I need to see the entire answer choices
      from the answer choice extended view .


   Task 1.2 Questions
   Did you have trouble figuring out how to select a single answer? If so, why?
   1. Yes . I was tapping on the answer several times, but the entire answer would keep showing . At first I thought
      I had to tap twice or three times to make my choice . I was really confused .
   2. Yes, I kept tapping the answer more than once . When I found out that tapping the answer displayed the full
      answer choice description I was lost .


   Was the drag and drop method intuitive?
   1. Not at all . The drag and drop technique confused me . The same motion used for dragging and dropping is
      the same motion used for scrolling up and down the screen . If all your answer choices are on one screen,
      how would you scroll back up the page to see the question again, without selecting or moving one of the
      answer choices?
   2. No

   Any suggestions for making this task easier?
   1. Don’t use dragging and dropping to select an answer . It would be easier to understand if you just press or
      tap the answer to select it . Also don’t change the current functionality of the iPhone features (since the
      iPod Touch is similar) . People are used of features behaving a certain way . Ie . scrolling, tapping to select .
                                                                                                    APPENDICES         | 13




    What I did like was that my answer choices appeared at the bottom of the touch screen . It makes it much
    easier if I’m reviewing the question again . I don’t have to scroll all the way down to see my answer selec-
    tions .
2. My first instinct is to tap the touch screen to select an answer . Its not obvious to have a drag and drop fea-
   ture . My suggestion is to add “drag answers here” at the bottom of the touch screen .


Task 1.3 Questions
Did you have trouble figuring out how to select multiple answers? If so, why?
1. Initially yes, but after I realized and learned how to use the drag and drop feature it was easy . I still do not
   like the drag and drop feature, its not clear when you see all your answer choices .
2. No


Any suggestions for making this task easier?
1. Again, don’t use dragging and dropping to select an answer . It would be easier to understand if you just
   press or tap the answer to select it . Its faster to tap for me, then to drag and drop .
2. To add “drag answers here” text at the bottom of the touch screen .


Task 2.1 Questions
Did you have trouble figuring out how to unselect your answer(s)? If so, why?
1. No
2. No


Any suggestions for making this task easier?
1. None
2. No


Task 2.2 Questions
Is it intuitive to view the rest of the answer explanation by scrolling up?
1. Yes
2. Yes


Is it clear why the selected answers in the black transparent box are certain colors?
14 | APPENDICES




   1. Yes . A red letter means wrong, green means correct . One thing I would like to add is if people are color-
      blind, how will they able to distinguish the colors?
   2. Yes


   Is it clear how to dismiss the answer explanation screen?
   1. No, I was looking for a button to push .
   2. No, I tried to move my pointer finger from left to right to get to the next question .


   After exiting the answer explanation screen, did you expect to see the next question?
   1. Yes
   2. Yes


   After exiting the answer explanation screen, did you expect to see the next question?
   1. To add a next button .
   2. To add some sort of icon to go onto the next screen .
