Adapted ride-on cars (ROC) are an affordable, power mobility training tool for young children with disabilities. But weather and adequate drive space create barriers to families’ adoption of their ROC.
CREATE Ph.D. student Mia E. Hoffman is the lead author on a paper that investigates the relationship between the built environment and ROC usage.
With her co-advisors Kat Steele and Heather A. Feldner, Jon E. Froehlich (all three CREATE associate directors), and Kyle N. Winfree as co-authors, Hoffman found that play sessions took place more often within the participants’ homes. But when the ROC was used outside, children engaged in longer play sessions, actively drove for a larger portion of the session, and covered greater distances.
Most notably, they found that children drove more in pedestrian-friendly neighborhoods and when in proximity to accessible paths, demonstrating that providing an accessible place for a child to move, play, and explore is critical in helping a child and family adopt the mobility device into their daily life.
RASSAR – Room Accessibility and Safety Scan in Augmented Reality – is a novel smartphone-based prototype for semi-automatically identifying, categorizing, and localizing indoor accessibility and safety issues. With RASSAR, the user holds out their phone and scans a space. The tool uses LiDAR and camera data, real-time machine learning, and AR to construct a real-time model of the 3D scene, attempts to identify and classify known accessibility and safety issues, and visualizes potential problems overlaid in AR.
RASSAR researchers envision the tool as an aid in the building and validation of new construction, planning renovations, or updating homes for health concerns, or for telehealth home visits with occupational therapists. UW News interviewed two CREATE Ph.D. students about their work on the project:
Augmented Reality to Support Accessibility
CREATE students Xia Su and Jae Lee, advised by CREATE Associate Director Jon Froehlich in the Makeability Lab, discuss their work using augmented reality to support accessibility. The Allen School Ph.D. students are presenting their work at ASSETS and UIST this year.
Congratulations to CREATE Ph.D. student Ather Sharif, Orson (Xuhai) Xu, and team for this great project on transit access! Together they developed UnlockedMaps, a web-based map that allows users to see in real time how accessible rail transit stations are in six metro areas including Seattle, Philadelphia (where the project was first conceived by Sharif and a friend at a hackathon), Chicago, Toronto, New York, and the California Bay Area.
Shown here is a screenshot of UnlockedMaps in New York. Stations that are labeled green are accessible while stations that are labeled orange are not accessible. Yellow stations have elevator outages reported.
Sharif, a UW doctoral student in the Paul G. Allen School of Computer Science & Engineering advised by CREATE Co-Director Jacob O. Wobbrock, said the team also included nearby and accessible restaurant and bathroom data. “I think restaurants and restrooms are two of the most common things that people look for when they plan their commute. But no other maps really let you filter those out by accessibility. You have to individually click on each restaurant and check if it’s accessible or not, using Google Maps. With UnlockedMaps, all that information is right there!”
Whether she’s researching how biofeedback systems can guide gait training in children with cerebral palsy or leading toy adaptation events, Alyssa Spomer is committed to advancing accessible technology.
A Ph.D. student in UW Mechanical Engineering (ME) and advised by CREATE Associate Director Kat Steele, Spomer is the student chair of CREATE-sponsored HuskyADAPT. Her studies have been multidisciplinary, spanning ME and rehabilitation medicine. She uses her engineering skills to understand the efficacy of using robotic devices to target and improve neuromuscular control during walking.
“Delving into how the central nervous system controls movement and how these systems are impacted by brain injury has been such an interesting aspect of my work,” Spomer says. “My research is a mix of characterizing the capacity for individuals to adapt their motor control and movement patterns, and evaluating the efficacy of devices that may help advance gait rehabilitation.”
In her dissertation work, Spomer is primarily evaluating how individuals adapt movement patterns while using a pediatric robotic exoskeleton paired with an audiovisual biofeedback system that she helped design. The Biomtoum SPARK exoskeleton works to sense and support motion at the ankle during walking, using motors worn on a hip belt to provide either resistance or assistance to the ankles during walking. The audiovisual system is integrated into the device’s app and provides the user with real-time information on their ankle motion alongside a desired target to help guide movement correction.
The audiovisual system that Spomer helped design (shown on a screen in the right photo) provides the user with real-time information on their ankle motion alongside a desired target to help guide movement correction.
Inspired by CREATE’s Kat Steele and the Steele Lab
Spomer was drawn to ME by the Steele Lab’s focus on enhancing human mobility through engineering and design. Working with Kat Steele has been a highlight of her time at the UW.
“I really resonated with Kat’s approach to research,” Spomer says. “The body is the ultimate machine, meaning that we as engineers can apply much of our foundational curriculum in dynamics and control to characterize its function. The beauty of ME is that you are able to develop such a rich knowledge base with numerous applications which really prepares you to create and work in these multidisciplinary spaces.”
This winter, Spomer will begin a new job at Gillette Children’s Specialty Healthcare. She’s excited to pursue research that aligns with her Ph.D. work. Her goal remains the same: “How can we advance and improve the accessibility of healthcare strategies to help promote independent and long-term mobility?”
CREATE is pleased to be a financial and advisory sponsor of HuskyADAPT, an interdisciplinary community that is dedicated to improving the availability of accessible technology in Washington and fostering conversations about the importance of accessible design.
HuskyADAPT is led by a team of UW students and six faculty advisors, including CREATE directors Kat Steele, Heather Feldner, Anat Caspi and Jennifer Mankoff. Open to all to join, their three primary focus areas are annual design projects, K-12 outreach and toy adaptation workshops, where volunteers learn how to modify off-the-shelf toys to make them switch accessible. The team also collaborates closely with Go Baby Go!.
Collaboration and diverse perspectives and approaches are at the heart of CREATE’s mission to make technology accessible and make the world accessible though technology.
One program developed by CREATE faculty looks at mobility solutions and ways to eliminate barriers. Hosted by CREATE associate directors Kat Steele and Heather Feldner, the Reimagining Mobility Conversation Hub brings in speakers from a variety of backgrounds and industries to inspire conversations about the future of mobility.
Working at a children’s hospital made me want to grow my knowledge as an engineer. There was just this disconnect of how we thought about technology, how we thought about what was possible, and what was actually available.
Dr. Kat Steele, CREATE Associate Director and Albert S. Kobayashi Endowed Professor of Mechanical Engineering.
How we move around really impacts our social relationships. It impacts our ability to participate in school, in jobs, in social events — it’s really one of our major connections to the world. The end goal of mobility is to engage in our lives and participate meaningfully.

On October 13, 2021 Karen Braitmayer shared images from her experience of— and critical goals for— inclusive architecture. Noting that the best and brightest designers might come in bodies that are different than employers expect, she called for design schools to welcome students with disabilities and for design firms to hire and support the careers of designers with disabilities.
First steps for designers:
Provide options: wider seats, different height soap dispensers, etc.
Learn about building codes and regulations.
Talk to folks who have already figured out how to accommodate for their own disabilities and hack for accessibility.
Architect Karen L. Braitmayer, FAIA, is the founding principal of Studio Pacifica, an accessibility consulting firm based in Seattle, Washington. Her “good fight” has consistently focused on supporting equity and full inclusion for persons with disabilities.
In 2019, she was chosen as the national winner of the AIA Whitney M. Young, Jr. award—a prestigious award given to an architect who “embodies social responsibility and actively addresses a relevant issue”. In the award’s 48-year history, she was the first recipient honored for their work in the area of civil rights for persons with disabilities. Braitmayer was also appointed by President Barack Obama to the United States Access Board, a position she retains today.
Join the Reimagining Mobility conversation
Join us for a series of conversations imagining the future of mobility. Hosted by CREATE Associate Directors Kat Steele and Heather Feldner, we connect and learn from guests who are engaged in critical mobility work – ranging from researchers to small business owners to self-advocates. We will dive deeply into conversations about mobility as a multifaceted concept, and explore how it intersects with other dimensions of access across contexts of research, education, and public policy.
You are looking for your first home – you’d like an open layout, 3 bedrooms, a big garage, lots of light, and easy access for your wheelchair. How many homes fit your criteria? Do the listings consider manual wheelchairs or bulkier powered wheelchairs with larger turning radii? These are just the start of the questions Barry Long would ask when viewing homes.
Barry Long is an advocate for people with disabilities who is helping to make real estate more accessible. In our third Conversation Hub session, Long shared how his passion for relationship building and helping others–combined with experiences as a manual wheelchair user, Dad and real estate broker–evolved into becoming a voting member of the Washington Building Code Council and advocating for standards for real estate listings.
Watch the conversation with Long about opening the door to accessible real estate and get a virtual look inside homes reimagined for inclusive living.
With the goal of making navigating our streets safer and easier for the mobility impaired, Jon Froehlich’s Project Sidewalk turns mapping sidewalks and improving pedestrian accessibility into a virtual game. To complete missions, users “walk” through city streets via Google Street View, labeling and rating the quality of sidewalks and features that make it easier—or tougher—to get around. They identify curb ramps, or lack thereof, assess their positioning, and point out tripping hazards.
Since Froehlich launched Project Sidewalk in Seattle in April 2019, users have mapped roughly a third of the city’s 2,300 miles of sidewalks and labeled nearly 70,000 curb ramps, uneven surfaces, potential obstacles like lamp posts, too.
