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.

Kat Steele, who has been busy advising four out of five of these new PH.D.s, noted, “We have an amazing crew of graduate students continuing and expanding upon much of this work. We’re excited for new collaborations and translating these methods into the clinic and community.”
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.

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?”
We are excited to celebrate the launch of a new research and innovation partnership between CREATE and the UW Institute of Learning and Brain Sciences (I-LABS) focusing on access, mobility, and the brain.
Mobility technology such as manual and powered wheelchairs, scooters, and modified ride-on toy cars, are essential tools for young children with physical disabilities to self-initiate exploration, make choices, and learn about the world. In essence, these devices are mobile learning environments.
The collaboration, led by Heather Feldner and Kat Steele from CREATE, and Pat Kuhl and Andy Meltzoff from I-LABS, brings together expertise from fields of rehabilitation medicine and disability studies, engineering, language development, psychology, and learning. The team will address several critical knowledge gaps, starting with, How do early experiences with mobility technology impact brain development and learning outcomes? What are critical periods for mobility?
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.

The award funds a program that will train four postdoctoral fellows to become leaders in rehabilitation research who can harness advances in physical computing and fabrication to enhance community living and participation with people with disabilities. Each fellow will complete a 24-month training program to build their expertise in physical computing, fabrication, rehabilitation, and disability studies. Training will address a shortage of people qualified to harness, deliver, and advance physical computing for rehabilitation research. The four postdoctoral fellows will participate in research, coursework, and mentoring that expands expertise in using primary and complex adaptation tools, 3D-modeling software, and fabrication machines (e.g., laser cutters, 3D printers) for rehabilitation applications. Their innovative research, publications, presentations, and community resources will amplify the impacts of this training program.
Dr. Kat M. Steele, an associate director of CREATE, presents at NIH’s Rehabilitation Research 2020: Envisioning a Functional Future conference on Friday, October 16, 2020. She will be presenting in the Mobility Across the Lifespan session with Bernadette Gillick, PhD, PT from the University of Minnesota and Levi Hargrove from the Shirley Ryan AbilityLab. This meeting highlights rehabilitation research and informs the congressionally-mandated NIH Research Plan on Rehabilitation Research to inform priorities for the next four years.
Dr. Steele’s talk “Normalcy Fallacy: Reimagining Mobility for Scientific Discovery & Innovation” focuses on examining how our assumptions of “normal” movement can hinder scientific and translational research to support mobility across the lifespan.
Mobility is a central part of accessibility and this new Conversation Hub, hosted by CREATE Associate Directors Kat Steele and Heather Feldner, provides a way to 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.
AccessComputing highlighted several research projects of UW CREATE faculty. An excerpt:
CREATE’s stated mission is “to make technology accessible and to make the world accessible through technology.” CREATE faculty pursue projects along both of these lines. Prof. [Jacob] Wobbrock was part of a team that helped make touch screens accessible by inventing Slide Rule, the world’s first finger-driven screen reader, in 2007. A research team including Profs. Richard Ladner, James Fogarty, and Wobbrock created GestureCalc, an eyes-free calculator for touch screens.
Prof. Jon Froehlich has created Project Sidewalk to use crowdsourcing and machine learning to gather and present outdoor navigation information, particularly the accessibility of sidewalks. Dr. Anat Caspi has a similar project called AccessMap, which provides personalized automated pedestrian routing.
Prof. Jennifer Mankoff conducts research on consumer-grade fabrication technology, such as low-cost 3D printing, and how this technology can be used to meet do-it-yourself or do-for-others accessibility challenges.
Professor Heather Feldner enables children with disabilities to explore the physical world through creative mobility support in her Go Baby Go project. [Kat Steele’s Open-Orthoses projects work with individuals with disabilities to co-design customized devices, rigorously test the devices, and provide open-source designs that accelerate development.]
For these and many other projects, CREATE faculty are already internationally recognized for their contributions to assistive technology and accessible computing; by bringing them together under one organizational roof, CREATE will enable synergies and foster collaborations that enable faculty and students to become more than the sum of their parts.
April 2020.Kat Steele, CREATE Associate Director and the Albert S. Kobayashi Endowed Professor of Mechanical Engineering, received a 2020 Faculty Appreciation for Career Education & Training (FACET) award from appreciative students. Presented by the Career Center @ Engineering, the award recognizes faculty members who have positively impacted their career and professional development.
