Keenly moving the design process of my project forward, I have decided to carry out a process of usability testing. To prepare for this, I’ve produced a paper prototype, depicting each screen of the app, as well as a loading animation, system alert, and a menu.
I’ve also created a “blinder” out of black cardboard, which will focus the usability tester’s attention on the window/screen of the paper prototype. As I’m attempting to prototype for a small-screen interface, this method will also ensure that I account for the display’s size when producing these prototypes.
Prior to carrying out my first Usability Test, I picked up a copy of Carolyn Snyder’s book “Paper Prototyping” at the University’s library, and have found quite a few tips inside.
Firstly, I made sure that I had a short list of tasks, that I would guide the tester into carrying out. I also made sure that I had a suitable camera on hand to record the test, as I would be hosting the test by myself, so would need to carry out the follow of facilitator, computer, and observer. These roles would usually be delegated to members of the research team however.
Next, I prepared a few key speeches, phrases, and questions, which I could rely upon to make sure that the tester remained informed and not led during the test. For example, I have adapted a usability testing script to make sure that I consistently introduce the tester(s) to each test. Any diversion from this introduction could lead to the tester reacting differently in the test itself.
I had to ensure that questions and affirmations that I gave in my facilitator role during the test were unbiased and did influence the testers actions. To do this, I ensured that my questions were open, and ended with “or not” if there were questions. E.g.: “Is this what you would expect the screen to look like, or not?”. I would also make the tester aware that I may not be able to answer the questions that they ask in the test, as to not influence them.
My next blog post will include a timestamped log of the Usability Test, as well as a summary and listed actions.
