User Testing: Future Air Food Systems

· · · · · · · · · · · · · · · · · · | Designing Meaningful Interactions

I started this assignment by adapting last week’s project into something a little more user-test friendly.

I started with this:


Stripped out some of the heavy design elements and included more visual clues (icons and graphics) to guide the user.

And ended up with these simpler (but, I believe, better) wireframes:

future air food order -- USER TESTING-01

future air food order -- USER TESTING-02

future air food order -- USER TESTING-04

future air food order -- USER TESTING-05

future air food order -- USER TESTING-06

future air food order -- USER TESTING-07

future air food order -- USER TESTING-08

future air food order -- USER TESTING-10

future air food order -- USER TESTING-09

I converted this into a simple Keynote presentation adding hyperlinks to the button areas. I used this for the Testing, asking users to touch the screen while I navigated the clicking from the background.

I tested 6 potential users and gave them each the same 3 tasks:

  1. Starting from the home screen navigate to the food menu, choose the first salad, add balsamic dressing and add it to the “tray”.
  2. Complete and pay for the order by using payment method 1.
  3. Start to place an order and then ask for an attendant.

Things went fairly well:

I learned a lot about ways to improve the design. The biggest message I received was that people wanted more feedback from the system.  They generally found the design easy to navigate except when it came to calling an attendant. The help page was confusing and the hierarchy of information needs significant work; the demo video and the largest call to action, “Place an order”, distracted the users from locating the call attendant button.

These tests also reiterated to me the importance of simplicity. In general, users seemed to want less choice; fewer ways to navigate through the food menu, for example. Of course, I was also reminded that the users wants to do less work; the fewer things the enter/type, the better.
