Features designed to encourage users to provide feedback on products and how they work on their pain points.

Everyone’s Alpha-Stim and mental health journey is different - and now you can see yours in real time.

1. Understand & Research

Alpha-stim - we got a problem.

Alpha-Stim is an electrotherapy device prescribed around the world by physicians and other healthcare professionals to effectively treat anxiety, insomnia, depression, along with acute, chronic, and post-traumatic pain.

The sales of the product is declining in 2021. The AS team was having hard time to use the existing database to identify the areas to improve. The executive board made a decision in early 2022 to develop a mobile application that is accompany with the product to fill the gap and hopefully inform how to improve the products.

What Alpha-stim wants to achieve through this application?

Goals

Captures real world data from Alpha-Stim users about their Alpha-Stim sessions and outcomes.

Provides progress analytics back to users, so they can visualize the impact of their Alpha-Stim on their wellbeing.

Unlocks potential for sophisticated analytics and greater insights through future data science on richer datasets.

What do we know about the users and what do they need?

Balancing business goals and user goals.

The key thing for this application design is to find out current problems that users have, in order to design an application that would meet both business and users' goals.

With the high-level direction, the design lead and I laid out the plan for the user research to further identify the problems and user needs building upon what Alpha-stim wants to achieve.

User survey

The reason why choose to do user survey is because the design will be very data and user engaging focus. We wanted to get more quantitative data for the decision making. We sent out surveys with $5 reward to over 200 users and received 63 responses. Below are the results of some key questions:

What would encourage you to take product surveys?

What are the expectations for the products?

What motivates you to use the application, if developed?

What prevents you from using the application, if developed?

User Persona

2. Defining the problems this product is trying to solve for users.

Users need a better tool to track their healthiness and effectiveness of the products.

Problem Statement 1: 

Users don't have a place to log the data to measure the effectiveness of the product.

Problem Statement 2: 

Users are unable to evaluate overall health in addition to the health improvement from using the product.

Problem Statement 3: 

Users can't track results and see overtime changes in physical conditions.

3. Balance the goals of the business and users to guide the product design.

4. Design concept & site flows

Log Session
Quickly log the details of the Alpha-Stim sessions, such as date, time, and current level, and rate how users felt before and after your session. See which settings gave users the best results, letting them personalize your treatment.
Task Assessment
Every 2 weeks, answer a few questions about how users are doing. These clinically validated surveys are the gold standard used by clinicians to gather powerful information about users' mental health and wellbeing.
Daily Check-in
Beyond using the Alpha-Stim, there are other activities that have an impact on mental health. With daily check-ins, users can keep a journal of user activities and mood without having to type a single line.
Progress Analytics
See the progress as users track sessions, activities, and moods. Which Alpha-Stim settings give users the best improvement? How long before users started feeling better? What daily activities boost the mood, and which ones make things worse?

Application structure and UI requirements

Site Map

The application map was created to understand the overall flow of the application and also to understand more from the data perspective - which part provides data and which part collects. This helps data scientists build the data model and pipelines for data collections and services - which is mainly why MDS got brought on.

Screens for General APP Functions

These screens are part of core functionalities that are necessary for an application to work.

Screens to Collect Data from Users

These screens center on functionalities were the user is asked to provide EPII with data about themselves, their stimulation sessions and how they are doing.

Screens to Display Data to Users

These screens center on functionalities to show users their progress and how they are doing. Almost all of these screens are data visualizations / charts.

Wireframes and flows

5. Interaction design

Problem 1: 

Users can't track results and see overtime changes in physical conditions.

Solution:

Use the data logged in by users to provide them with an overview and overtime changes.

Log sessions for different use purposes

Users can log sessions for different use purposes - anxiety, depression, or others, pain, and insomia

Record sessions with overall experience

Users are allowed to rate the overall state before and after using the product for each session.

Problem 2: 

Users are unable to evaluate overall health in addition to the health improvement from using the product.

Solution:

Develop matrix to measure other factors contributing to health to help users monitor their overall health condition.

What are the key factors contributing to overall health?

A follow up questions were sent to the users who took the first survey and mentioned overall health in the comment sections. we received 68% respondences. Among received answers, we identified two factors that users consider as key for their overall health apart from the product treatment: Activities and Mood.

Daily checkin for activities and mood.

Users are allowed to do daily checkin for different health elements such as sleep, self care to better monitor their overall health.

Problem 3: 

Users don't have a place to log the data to measure the effectiveness of the product.

Solution:

Track data logged by users and provide an overview of overtime changes and trends.

Track symptoms overtime changes

Users can view the overtime changes of the session they login in different timeframes and different views. Users can also unlock trends of the logged sessions.

Track health overtime changes

Apart from product sessions, users are also allowed to review the overtime changes in their overall health conditions - with the daily checkin data.

Data Visualization

I worked closely with the data team and design lead on different data visualization to make data more interpretive and intuitive.

6. Usability testing

The testing was conducted among 10 people. Users were asked to complete 3 tasks and review ALL screens.
The design is well received in general. 86% of users were able to complete the tasks given to them without having any barriers.

Virtual Interview

10 people were guided to download the application and completing tasks. Users shared screens during the whole session. I was able to observe and ask questions while they were completing tasks.

After completing tasks, users were asked to review each screen and finish the questions for each screen, including multi-choice questions and open-ended questions (what can be improved for example).

Design Improvements

Landing Screen

7/10 participants mentioned that the analytics were the most interesting part and 5/10 commented it would be nice to see major analytics when they land on the application.

The design team explored multiple design layouts and patterns. The design iterates from four equal entry points to four entry points but with progress analytics as focus.

The design changes was to put emphasis on logged user data to capture user eyes and encourages users to engage more with the app.

Log Sessions

The design for log sessions started with card format including session details and buttons for view and edit.

During the usability testing, users found it very difficult to recognize key information and take action actions from there.

In the design iteration, we changed the card format to column view to provide more overview feeling to users and let users to view and edit session when they get into session detail screen.

Select Pain Points

The pain point selection screen was to allow users to report their pain areas when using the product and logging a session.

The main challenge here is how to make the selection easier for users. The design started with points highlighted on a body. However, users found it difficult to select during the testing sessions.

In the final design, we changed the selection from points to buttons to provide users with smother selections.

WHAT I LEARNED FROM THIS PROJECT?

Balancing the good user experience and meeting the business goals is the most challenging part. How can we engage users to use the application so that the company can collect the data for analytics is the whole spectrum of the product. I did find the user research and usability testing part is really useful in uncovering what user really need from this product. In design, the exploration of different visualizations to better communicate with users also helped me learn a lot.
