Here we created a Low-Fidelity prototype to test what are the necessary functions of our application and what are the most intuitive gestures.
Our low-fi prototype gave an illusion of a floating image. Interviewees can interact with the application using finger and hand gestures. During the interviews, there were always two interviewers and one interviewee. One of the interviewer held the application and interact with the user, and the other interviewer asked questions and took notes. The interviews are designed to test how well the interactions of this application work. We encourage the interviewees to think aloud and let us know what’s on their minds when using the application, and be as honest as possible.
We categorized the interviews into three main tasks: examine the human body, examine a specific body part, and take a quiz.
For task 1, examine the human body, our goal is to have them look at the human body, rotate it, zoom in/out of body parts on the current layer. Our questions included: “As an anatomy student, do you need to take a closer look at certain body parts?”, “Do you need to zoom in at certain parts on the same layer?”, “Say you want to take a look around the head, and take a closer look at the iris of the eye. How would you do that?”
For task 2, examine a specific body part, out goal is to have them look at a specific part inside the body by stripping off layers, zoom into a section and remove layers which float around in space, put layers back if wanted, layers are transparent if they don’t fit in the full zoom window. Our questions included: “Say you’d like to take a closer look at the lobe of the left brain. You can take off layers of the body by system in this application. How do you think you would do that?”
For task 3, take a quiz, our goal is to see what kind of quizzes they would want, and how they would interact with it. We suggested “body flashcards”, which allows users to select a body part to see the name, change it to red if they got the name wrong, change it to green if they got it right. Our questions included: “If you have a test on Thursday and need to study, would you use this application?”, “Would you be likely to use the quizzing app?”, and “How would you open the quizzing function and use it to study?”
