A Personal Assistant for Kids with ADHD



ADHD is a mental disorder that most often occurs in children. 6.4 million kids in the U.S. aged 4-17 are diagnosed with ADHD. It is characterized by difficulties with attention, hyperactivity, and impulsivity, frequently takes root during childhood, and can significantly impact a child's daily life and educational progress.


The biggest challenge is that when kids are 6-10 years old, they often show clear signs of ADHD when transitioning to classroom environments. This project aims to create a solution to the daily life of kids with ADHD at early stages and also get parents involved effectively in helping their kids.

One experience, multiple controls

MeMoWatch is created to help kids complete daily tasks more efficiently while providing personalized assistance. The device also seamlessly integrates with a mobile app allowing parents to provide guidance and effortlessly keep track of their children's daily progress, even from a distance.

Design Process

During our design process, I focused on defining the unique habits and solving challenges faced by children with ADHD. I also had a chance to design a user experience for multi-platforms, from digital to physical interfaces, including human factors, sizing, materials, colors, typography, etc.

Market Key Findings

Although wearable devices are popular, concerns about their complexity for kids are found. Some therapy devices also use science-based treatment, but users refer to a more user-friendly design.

Emotional Journey:
Keep them motivated

MemoWatch's tone of voice is all about motivating kids to stay on track with their tasks, memorize important steps of a big task, and form consistent habits. By gamifying the process of memorization, MemoWatch makes the journey more engaging, rewarding and motivating.

MemoWatch also aims to be there as a reliable assistant and a friendly companion, always ready to help, talk and share. With MemoWatch, memorizing and completing the tasks become an exciting adventure.

Initial hypothesis from real data

During my first round of research from public data and patient reports, I found a list of functions people need and features that are actually helpful based on time-management-focused product reviews from users and was trying to implement these key functions into the design thinking process.

In-depth conversations with ADHD Patients

I had a chance to talk with 2 ADHD patients who have been diagnosed since their young age. I came up with a list of questions focusing on learning how they have been living with ADHD and the role of technology in the process of assisting with ADHD.

Key Insights

From here, I compared the answers from our conversations with my initial thoughts (from secondary research) and made a deeper step toward understanding my user and designing a better experience in the school environment.

to Final Solution:
Memorizing has never been this fun.

Key Functions

#1: Stay on Track

Each action/routine are now be divided into small steps (with timer for each step) so kids can engage and complete their routine more effectively and enjoyably.


After completing each task, kids will earn points and rewards, such as hero badges, etc. The key is to gamify the experience of focusing & completing the task - which helps kids feel motivated to keep earning points, building achievements & forming memories.

#3: Emergency Assistance

MemoWatch Personal Assistance is always available whenever kids need to contact their parents, or just simply need to talk to someone. Our MeMo AI will provide engaging and comforting responses based on the input.

User Flows:
Minimal, and Fun

I worked on the overall user flows with the goal to craft a quick and easy experience for the kids to achieve the task, but at the same time to create enjoyable and motivating interactions.

The user flows of the linked mobile app is also crafted to be the most convenient for parents to manage the tasks for their kids as well as keep track on their child's situations.

Visual Design

After the first round of prototyping, I was able to test my design with 3 different users from my target age group. A lot of insightful feedback was found, mostly focusing on keep working on the transitions between screens and multimodal interaction-feedback.

Sizing & Materials:
Kid-friendly, first.

Working on the size, I emphasized a strong focus on safety and comfort, this watch is specifically designed to fit kids' wrists while prioritizing safety. A potential material option could be durable rubber: gentle on sensitive skin and highly durable. MemoWatch also features a clear, easy-to-read face & easy-to-focus face for kids to achieve their goals.

User Validation:
"Haptic Feedback helps"

After the first round of prototyping, I was able to test my design with 3 different users from my target age group. A lot of insightful feedback was found, mostly focusing on keep working on the transitions between screens and multimodal interaction-feedback.
