Context

Every child deserves tailored care, but large caseloads make it difficult. NLOne helps providers bridge the gap.

NLONE Cloud is a one-stop platform where child disability providers (OTs, PTs, reading specialists) buy, use, and create personalized activities for their children across different skill levels, age ranges, and disabilities.

NLOne helps providers...

Purchase activities from the provider community

Use activities with children during sessions

Create custom activities for their children

Problem & User Research

The current interface was mired with failed interactions, increasing work instead of reducing it.

Let’s conduct a usability test…

Main tasks

  1. Buy an activity

  2. Find and start it

  3. Create a basic addition activity

Success metrics

  1. Errors per task

  2. User rating (How intuitive task felt, 1-10)

Tasks were unfamiliar, overwhelming, and misaligned with their workflow.

= Misclicks during a task

Hidden Checkout Process

An overwhelming interface

Lack of workflow similarity

Solution preview

Redesign that reduced usability errors by 84% and increased user rating by 52%

Decision 1

Using activities should feel simple and focused

When using activities with children, specialists need to quickly work through questions without being distracted by details.

Keep primary actions the main focus

BEFORE

Grading buried under cluttered UI

  • Hidden in a group with 10+ other buttons

AFTER

Grading is largest action

  • In separate section from other buttons

  • On right-hand side for easy access

Visual Design Iterations

Finding the right layout was a process of reducing visual noise, refining grouping, and adjusting touch target sizes.

Decision 2

Creating activities should be flexible + workflow-aligned

How can we provide enough structure for detailed activity creation without constraining what providers can design?

More customization potential, less complexity

BEFORE

Single-page customization

Customization options were jammed in to 1 page, creating overwhelm and limiting customization

AFTER

Step-by-step question creation

Multi-step layout gives more space for customization, while progressively disclosing information.

Remove unnecessary roadblocks

BEFORE

Required categorization

  • Users froze at this step, unsure of how to integrate this with their activity needs

AFTER

Optional categorization

  • Users can quickly skip over categorization if it makes sense for them

User Feedback

Making activity creation more discoverable

There was an 84% reduction in task errors and a 52% increase in user rating. However, usability testing showed activity-making was hard to find...

Increase touch targets (Fitt’s Law)

INITIAL ITERATION

‘My application’ button is too small

  • 3/5 users did not find correct button

FINAL ITERATION

Larger entry-point

  • A separate, larger surface area entry-point in to activity making makes it more noticeable for users

Support users mental models

INITIAL ITERATION

No way to find activity creation from nav

  • Users’ first instinct was to search the navigation bar for a “create activity” section

FINAL ITERATION

Users can select activity creation from main nav

  • Create a direct opportunity to create activities through the menu!

Final Design

An intervention platform that is streamlined, familiar, and intuitive....

Buy activities you need like second nature

Buying an activity feels like other common e-commerve websites.

Work through activities with your child without getting overwhelmed

Make your own activities to match the exact needs of your child

Reflection

What I’ve Learned

Observation > Metrics

While usability data was a good representation of the UX, there were other behaviors (such as staring at a screen before acting) that tell a deeper story.

Go for the big change!

It is easy to want to change as little as possible during a redesign and focus on key painpoints. However, I’ve learned that taking risks and adding your own vision can take a product above and beyond.

Be a proactive leader

Especially in startup environments with high ambuity, it’s important to initiate key design processes, like usability tests and iteration cycles.
