After the lo-fi user testings, we concluded the most commonly adapted gestures and the additional functions that were suggested by our interviewees.
For zooming in/out, most people suggested pinching with two fingers, or grabbing and releasing. For rotating, grabbing the model and turn the hand, sideways swipe with vertical palm, or one finger sideways swipe are the common gestures the interviewees did. For taking off layers, grabbing a layer and groping motion away is the most common gesture among the interviewees. For isolating a body part, some people suggested to use a grabbing motion to select a body part and after the selected body part is highlighted, use a groping motion to take of the layer. Some also suggested to use a menu or a cursor to select a body part, and swipe to the left to peel it off. For navigating to the quiz, most people suggested to go through menu and choose a specific category. Some people prefer to swipe up the menu from the bottom; some people suggested to swipe left from right top corner. And most of them would like to be able to access to the menu anytime to switch a category. For the quiz contents, open-end question, multiple choice, and truth-or-false are all popular among the interviewees. Most of the interviewees expected various question type instead of simply asking the names of body parts. Furthermore, questions such as tracing the pathway of a hormone, where it’s produced, where it’s secreted, and what it influences, etc. are more advanced questions.
Additionally, some interviewees suggested us some functions that they would like to use on our application. Couple of the interviewees suggested that it would be helpful to show names of body parts when they point at them on the application. In addition, they would also want to be able high light the body parts during a group study. Some people also suggested that they would like to be able to search for a specific part of body through a search bar and with maybe physical keyboard. Lastly, a tool bar is also requested by many interviewees. Users would like to be able to easily switch between different functions such as show-name function, or zoom in/out function.
After gathering all the most intuitive functions and gestures, we will be able to design our hi-fi prototype, which will be closer to our real application.
