Project 2: Lo-Fi App Design Prototype

Task to do:
1. create a lo-fi prototype 
2. test the app with three testers 

Create lo-fi prototype

I used Figma to make prototype. The reason why I chose figma is that I have studied how to use Figma a little before, so I have a basic understanding and it is easy to use it. Besides, I can also have a deeper understanding of the operation and other special functions of this software.

I have already downloaded a version of the prototype of lo-fi in the proposal stage, so I have enough time for this project 3. I made modifications and changes on the basis of the original and made modifications according to the presented effects and the feedback of the lecturer.

When users enter this page, these pages will be displayed for users to log in or create accounts. If it's the first time users to use it, they will first ask to register their accounts and conduct a simple preference survey, so that they can customize the recipes suitable for them.

REFLECTION


I think this assignment is still within the scope of my ability to handle. I'm talking about the difficulty of homework in time. I think the most important thing I learned in this assignment is how to operate figma to complete my protoptype. There is another part, user testing, which I also find quite interesting. I think it's very interesting that people other than myself and lecturer try out my app and can observe their usage habits and fluency. Of course, this also provides great help for my application design, which can more intuitively see the situation and problems of users when using the application, and facilitate my subsequent improvement and progress. On the whole, this assignment is not difficult for me, but it is very interesting.
