What I do    
I'm a full stack-designer and digital artist who uses agile user-centered methodologies in all things I do. I specialize in user experiences, visual design, content marketing, and strategies.

Take5Diet Mobile

Take5diet is a healthy eating control app that helps track your daily fruit and vegetable intake and promote healthier eating. Users can see if they have achieved the recommended 5 a day through weekly or monthly views to better balance the nutrition intakes.

The product's target audience is people who are at the age of 25 and plus and across a wide range of communities (family and friends, neighborhood, grocery store customers, working professionals, stay-home parents, and retired individuals.)
The Goals: 1) Research for accessibility to healthy affordable food. 2) Increase awareness of the impact of a healthy food intake upon physical and mental health among the target audience. 3) Create personalized mobile assistant to help individuals and families to maintain a healthy diet.

The Challenge: discover the potential invisible issues that prevent people from having a healthy eating habit.

Research & Discovery

Field Research & Planning
In order to learn the reasoning behind keeping people away from eating healthily, my teammates and I planned out field research to the local community to help us better understand people's concerns and pain points.
Interviews with Focus Groups and Experts
During the field research to local communities (offices, neighborhood, school parking lots, grocery stores, and on the streets of Financial District), we interviewed working professionals, elementary school parents, nutrition experts, and grocery shoppers. We try to ensure a certain level of diversity as having a fair result of the research.
Sample Interview Questions & Quotes
We prepared interview questions and recorded the answers from participants to use as the reference for defining the common issues among them.
User Persona
Based on the previous research as well as incorporating the needs, goals, and observed behavior patterns, we created user personas to help us better understand the target audience.

Define & Analyze

Organization & Prioritization
After returning from the field research, the team sat down and wrote the findings on sticky notes to review them together.
Issues Discovered
We put the sticky notes on the whiteboard trying to see the bigger picture of the findings.  Then divided them into different categories. From the list, we picked the most frequently mentioned (by participants) three categories to further investigate: Pricing and Payment, Location, Cooking Method. 

Here are the major discoveries we found out during the process: 

  • Limited access to healthy food options (among Mexican communities in San Mateo County)
  • Long-term unhealthy eating habits affect food decision making
  • Limited consumption of healthy food (cross communities and tech employees)
  • Lack of awareness of the impact of a healthy eating habit
  • The financial situation affects food decision making
  • Job type and work hours and perceived time barriers affect eating habits

Ideate & Create

Refine Objectives & Competitive Analysis
After identifying the issues, we refined our objective which is to design a diet tracker mobile application that encourages people to complete daily healthy diet milestones in order to maintain a healthy eating habit.

Additionally, we also researched the similar products (like Weight Watchers, My Fitness Pal, My Net diary, etc) in the market for brainstorming and inspiration purposes.

Brainstorming & Sketches
Based on the previous research and findings, the team decided to put the focus on three key features:
  • Dashboard: provide an overview of basic stats
  • Progress Tracker: food intake meter
  • Nutrition Library: resources and references 

Then the team started brainstorming sessions to discuss user experience flow and share thoughts. We sketched out our ideas on paper as well as on the whiteboard.

Wireframes & Prototype

Low-fi Mockups
Based on the research findings and brainstorming results, I created low-fidelity mockups for stakeholders to review to get further feedback which also gives flexibility for the team to iterate on the design at the early stage and avoid any wastes during the development process.
Baisc Style Guides
Since the team started the product from scratch, when it comes to hi-fi mockups, a proper style guide has to be set up first to ensure the consistency of future implementation.
Hi-fi Mockups
After the style was defined, we moved forward with creating high-fidelity mockups and prototype for another round of usability testing to get feedback and refine the design.

Test & Validate  

Usability Testing
Usability testing is involved in every key stage of the development process to help the team looking for design flaws and pain points to reduce user friction and improve the experience of the product. 

The tools we used for usability testing mainly include pen and paper (paper prototypes) and the online prototyping tool InVision.

A/B Testing
A/B testing is also used by the team when to compare two versions of the design to see which one performs better among users. Create apple-to-apple test by clearly defining fixed elements and variables is the key to a fair and constructive result.
