9. Medium Prototype Details about Me Evaluation

Medium-fidelity prototypes

Welcome interface, Login interface and sign on interface

In the lo-fi prototype, we will improve the logo and interface content.

Recording data interface

In this part, we also continue to improve the matching colour of the details of the interface, but It is important to note that here, we present two sets of designs. However, due to the consideration of the overall interface, for the purpose of simple design, we finally decided to use the four interfaces as the Recording data interface in the group meeting.

Sub-interface

• Homepage: We designed the game interface.
• Diet interface: We improve the diet icon.
• Exercise interface: The game interface is perfected.
• Friend interface: We have perfected the colour of the friend interface.
• Additional interface: It is worth noting that during the design of our lo-fi interface, two sets of solutions emerged. One is to use the previous record diet calorie and food recommendation interface. The other is to increase the ar scan part. The user can click the icon in the upper right corner to enter the are scanning interface. When the user scans the food, the calories of the food will appear on the screen. Which of these two options is chosen is in-depth, and we will decide based on the results of the assessment.

User scenarios

Interaction flow

Evaluation

Test plan goal

Testing if the users are satisfied with the current prototype, the main parts including as following:

• Functionality
• Interface design
• Interaction method
• More users suggestion about this prototype

Test method

• Open question Interview

Test question

First, let the user use the APP, and then observe some unsmooth use flow in the user's use process and record it.

About question Interview

• Can you outline some of the features of this App after use?
• Can you understand the function of this software?
• Are you satisfied with the interface design including color matching?
• Do you think the interaction flow of the app is reasonable?
• Do you think this App is useful to you? Why? If you believe it is useless, please explain why.
• Do you think there is still room for this software to be modified?

Feedback and change Summaries

According to the second cycle users' test, we summarized the feedback from users and gave some changes about the prototype to make the Iterative design 1.Game interface pages a)Three people feedback that they can not understand the game in the app.

2.Exercise interface pages a)The yellow bar on the exercise page can not understand b)exercise model is not clearly show 3.Friends interface pages a)Add more interaction when people b)The friend button should be placed inside the exercise c)Other people's profiles. 4.Homepage a)The navbar should make a change 5. Other a)AR scanning looks unnecessary.

Change

1.The home icon is not at the same level as the other three. We would magnify it later. 2.Many users don’t know how to play the game. Usually, they felt confused about the game's rules and pages’s icons (calories burning bar， teams battle and so on). it is better to add an introduction to the game pages for the purpose of making users easily understand the interactions and game playing.

3.We did evaluations referring to this prototype to test its functionality. Many people campaign that AR scanning function is too boring, which they would rarely use. It is just a calories calculating function that is the same as other normal applications’ data tracking, even though in another form.On the other hand, in the DECO 7350 class the teacher said Ar function seems to be useless in the application. In addition, it is also difficult to implement this function because of technology limits. Hence, we gave up AR function.
