According to the CDC, 61 million adults in the United States live with a disability. Of the people with disabilities, 13.7 percent have a mobility disability with serious difficulty walking or climbing stairs. That's about 8.4 million people in the U.S. who use wheelchairs or mobility aids.
For many of these individuals, accessibility in different environments is a daily challenge that has a profound impact on the way they navigate their daily lives.
People on wheelchairs experience accessibility issues when trying to navigate a public place. Often, they have to call a place of interest ahead to ensure that their accessibility needs are accommodated, i.e. parking spaces, doorways, ramps, seating.
The need to plan ahead with lack of information causes stress, arguments, and tension for wheelchair users.
On the other hand, businesses who do not list their accessibility information are missing out on revenue because of the lack of visibility upon research.
How might we make business information (like restaurants, museums, etc) about accessibility accommodation easier to find for people who use wheelchairs?
RampUp is a mobile app that allows wheelchair users and caregivers discover, rate, and review authentically accessible places near them.
User-Centered Design Process
Usability Testing + Iteration
We believe that a mobile app that provides information about accessibility features of public spaces (restaurants, museums, etc.) for people with physical disabilities (i.e. individuals in wheelchairs) can help them make more informed and confident decisions when choosing a destination.
The following research objectives were what I wanted to uncover during my user interviews:
• Their thought process and habits when planning an activity
• The priorities, concerns, and barriers they run into when planning an activity
• Preferred tools they use to plan and make decisions
User Research Conducted
Nine total participants via user interviews and a survey
Proto Persona: Meet Sarah James
Thought process and habits
Where users most likely go out to
Amenities most important to users
User Persona: Meet Courtney Gryffin

I don’t want to make a scene, it’s embarrassing.
Will the restaurant pick up my call? Will the hostess know what accessibility features I’m referring to?
Is their elevator working or a ramp to the entrance? Is there enough space for me in the restroom or between the aisles for me to get through?
Is the table too low/too high for my reach on the wheelchair?
I put myself in Courtney's shoes and thought about every point in her journey to understand her needs, concerns, and desires to identify opportunities for every moment.
I listed out each step and mapped them out as a flow to break down what it would take for the user to achieve specific tasks.
As a group, we each sketched our own screens to get a more intimate idea on what the layouts and elements will look like before going digital. We reviewed our sketches altogether and curated the best representation of our flow and features from the collection.
Creating detailed wireframes and interaction flows helped make navigating between screens specific to the user tasks straightforward.
I took inspiration from visual accessibility signs seen around the world.
Because low vision is often a co-morbidity that wheelchair users experience, it was important that the interface is high-contrast and Web Content Accessibility Guidelines (WCAG) compliant overall.
Final Visual Design
The high-contrast design with large fonts and familiar elements were based on my learnings from the visual needs of our users.
Seven individual user tests (six female, one male) were conducted over Zoom using a testing plan with outlined tasks based on the user flow.
Participants were asked to share their screen while navigating the high fidelity prototype.
All participants were able to accomplish all tasks with little-to-no issues, but did provide feedback on the flow of the app:
This would make life so much easier when it comes to finding places for our clients. I can target what I want and I can get the information immediately.

It would be nice if I could create a profile with my specific needs. It would be helpful if the app sent pre-programmed messages to the restaurant, because I often have to copy and paste my requirements and sometimes I forget things.
– Caregiver, 57
I really like that you included table heights and aisle width. I think that's an important thing that goes unnoticed.

If I could develop this app further, I would:
