User research & Synthesis
To kick off our research, we created 2 version survey in English and Farsi languages which helped us generate the initial data needed to understand our target audience and their behaviors. We received a total of 127 responses from both surveys.

Key Research Finding:

-Desatisfaction of dermatologist
-Trust in AI feature
-Lack of time
-Forget their routine
-Lack of knowledge about products


* Users Criteria: Users who give a high importance of online skin care
From 127 participants in our survey we interviews 31 of them.
We selected them according their data in survey such as being familiar with skincare routine,familiar with AI and Apps.
Key points in our interview:
1. Personalized Skincare: Discuss how AI can analyze individual skin types and conditions to create personalized skincare routines.
2. Skin Analysis: Explain how AI algorithms can assess skin conditions, including acne, wrinkles, and dark spots, using images or data from various sources.
3. Customer Engagement: Discuss the role of AI in enhancing customer engagement through chatbots, virtual beauty advisors, and product reviews.
4. Consumer Education: Emphasize the importance of educating consumers about AI skincare technologies and how to use them effectively also about skincare products.

At the end of our research and by using all data we created a persona, Betty
Betty, a 30-years-old professional designer who leads her to a busy life. Betty is passionate about skincare and her health. She is a social person who enjoys new technology.

Competitive analysis:

We compared our application with 5 other skincare application/website which all had AI featured and we founded:
1. Almost all of the competitors have :
-AI feature
2. Non of them have
- Videos
3.Most of them do not have
- Review

Increasing Fidelity

Mid to High-Fidelity Prototype

After usability test, we need to update a few things to avoid confusion for the users.
-Home Screen buttons: Updated to give better contrast of the color
-Schedule page:
*Made aesthetic changes to “Plan” and “See week” tabs
*Increased trigger area for closing the scheduler
*Removed shadow on icons so users do not confuse them with clickable buttons


Usability Testing

High-Fidelity Prototype

After we designed High-Fidelity prototype, we conducted a usability testing with 3 users.
Each team members participated together, conducting the test, video & audio recorded.

- Tasks
3/3 users were able to complete the followings;

  1. Set a weekly goal to bike 2x a week

  2. Schedule a bike ride for Tuesday and Thursday

  3. Log today’s 2 hour bike ride

​- Usability Results
The scheduling task presented them with minor issues:

  • 3/3 users had trouble closing the pop-up menu

  • 1/3 users tried to click on the activity icon within the day of the week

Usability Testing:

Our team conducted multiple rounds of testing involving both users and fellow designers. Based on the feedback received from these evaluations, iterative changes were implemented to continually enhance the design


AB Testing:

In pursuit of design excellence, our team conducted 3 A/B tests as part of this project. These tests played a crucial role in refining the user experience and making data-driven design enhancements. They were instrumental in shaping the final website design, showcasing our commitment to user-centric design and continuous improvement.
