Better data sets that capture the varied experience of people with disabilities

Better data sets that capture the varied experience of people with disabilities are crucial to building better accessibility solutions. Mankoff has been involved in multiple pioneering data collection efforts. Most recently, her work capturing fine-grained, longitudinal behavioral data about the experiences of college undergraduates with and without disabilities has allowed her to study the unequal impacts of COVID-19’s changes to society on students with disabilities. She has also collected, and is currently exploring the first data set containing fine-grained end-to-end trip data about over 60 people with disabilities, combined with self reports of successes and failures. In the past, she collected over a year of real-world mouse data from individuals with various impairments, a data set whose size is unparalleled in a community that usually tests ideas on 1-10 individuals in lab settings. With this data, she was able to pioneer pixel based analysis methods that could improve on standard accessibility APIs, achieving a shift from 75% to 89% in accuracy identifying on-screen targets; demonstrate the huge variability within a single user and among many users with impairments that affect desktop computer use; and develop classifiers that could dynamically determine a user’s pointing ability with 92% accuracy on a single sample.

Better understanding of clinical and DIY accessible technology production

The advent of consumer-grade fabrication technology, most notably low-cost 3D printing, has opened the door to increasing power and participation in do-it-yourself and do-for-others accessible technology production. However, such production faces challenges not only at the level of process and policy, but with respect to materials, design tools, and follow-up. As summarized in a 2019 Communications of The ACM article, Mankoff has led the effort to better understand both clinical and DIY stakeholders in this process, and developed better, more usable tools for production. Together, these can enhance the capabilities and participation of all users in today’s  manufacturing revolution.

AccessSIGCHI directorship

Mankoff is the long-time director of AccessSIGCHI, the national group that has helped to improve conference accessibility in one of ACM’s largest professional groups, and is working collaboratively to help set standards and document best practices for use across ACM.

Jacob O. Wobbrock

  • CREATE Co-Director Emeritus

The CREATE community thanks Dr. Jacob O. Wobbrock for three years of leadership as one of our founders and CREATE Co-Director Emeritus. A bright idea was sparked in 2019 at Microsoft’s IdeaGen 2030 discussion panel, where Wobbrock spoke about ability-based design. Wobbrock and panel member Katherine Steele, a CREATE associate director, thought that a center could bring faculty together and make them more than the sum of their parts. He returned to Microsoft with Jennifer Mankoff, Richard Ladner, and Anat Caspi to pitch Microsoft’s Chief Accessibility Officer, Jenny Lay-Flurrie, to support the new center. With additional support from Microsoft President Brad Smith, the center was launched in Spring 2020. Wobbrock, along with Mankoff, served as CREATE’s inaugural co-directors until June 2023.

Research highlights

The Slide Rule project invented the world’s first touch-based finger-driven screen reader for smartphones. The interaction techniques employed by Slide Rule influenced Apple in their creation of VoiceOver, their built-in smartphone screen reader, and subsequently TalkBackon Android. Developed from 2007 to 2008, today Slide Rule has directly influenced products shipping on billions of touch devices. This work was recently honored for its impact.

A new design approach developed from 2008 to 2020 that emphasizes what people can do and seeks to tailor technologies to people’s specific abilities through adaptation, customization, and ability-focused design practice. Interfaces that adapt to their users’ abilities, touch recognizers that model their users’ touch behaviors, and mouse cursors that dynamically adapt their speeds to make pointing more accurate were all projects that came from, and informed, ability-based design, whose 2018 Communications of the ACM article has been influential at major companies, including Microsoft.

Mouse pointing and text entry are still the most fundamental inputs we give desktop and laptop computing systems, but for many users, these bedrock input capabilities are still inaccessible. Since my own doctoral research from 2001 to 2006, I have been inventing and evaluating more accessible means of providing input to computing systems. For example, my ;EdgeWrite technology provided more accessible text input using handheld devices, wheelchair joysticks, touchpads, and trackballs. Recently, my Pointing Magnifier 2 software, originally a research project with Leah Findlater, provides a cursor replacement on Microsoft Windows that has been useful to people with motor or visual impairments, older adults, and graphic designers.

Equity in Transportation Data

All travelers want directions they can trust, but most maps and automated pedestrian routers do not have the data travelers with accessibility requirements need. When we built AccessMap, a personalized, automated pedestrian routing application that takes mobility limitations into consideration, it was clear that municipalities and agencies have not been effective in collecting and maintaining detailed pedestrian-centric map information. Users of AccessMap, currently served in Seattle, Bellingham, and Mt. Vernon, have made it clear with over 35,000 routing requests that people of all abilities require better mobility apps that provide customized information about the pedestrian environment. To scale our efforts, we created the OpenSidewalks data standard along with understandable tools for gathering sidewalk network data, focusing on (1) tools for individual citizen-scientist data entry (2) mass import tools for municipal datasets, and (3) automated computer vision pipelines to map geo-located videos. Our standard and methods for effective data exchange and sharing were recently adopted by King County Metro, Sound Transit, and MVTransit Inc, the largest paratransit operator company with worldwide presence.

The Taskar Center for Accessible Technology (TCAT)

An initiative co-founded by Anat Caspi at the Paul G. Allen School of Computer Science & Engineering to develop, translate and deploy open source, accessible technologies, with a focus on benefiting individuals with motor limitations or speech impairments. TCAT’s translation efforts promote collaborative use of data commons and shared community resources with the recognition that bringing novel accessible technologies to users requires challenging the traditional technology-transfer path. With our partners, we launched the first assistive technology and adapted toy lending library in the Pacific Northwest, serving physical technologies and online resources for others to replicate. Over the past 5 years, TCAT has engaged more than 200 undergraduate and 50 graduate design and engineering students in participatory design and inclusive design practices with our communities of practice, bringing together people of diverse abilities, backgrounds and skill sets towards a common goal of designing for the fullness of human abilities and experiences.

Perkinput

Perkinput is a non-visual text entry method for touchscreens based on Braille developed by Shiri Azenkot, a student of Richard Ladner and Jacob Wobbrock.  The method does not use specific targets but tracks fingers as they type six-dot Braille characters on the screen. Braille can be input with one hand on a small touchscreen or with two hands on a larger touchscreen.  In studies users can type up to 17 words per minute with one hand and 37 words per minute with two hands with high accuracy.  Braille-based text entry is now common on touchscreen devices.

Blocks4All

Blocks4All is an accessible block-based programming environment for young children developed by Lauren Milne, a student of Richard Ladner.  Block-based programming environments like Scratch, Alice, and many others are the most popular for young children to learn computing concepts such as conditional and loops.  Unfortunately, none of these environments are accessible to young screen reader users. Blocks4All is the first block-based programming environment for touchscreen devices that is fully accessible.

AccessComputing

AccessComputing is a National Science Foundation program, founded in 2006 and centered at the University Washington, with the goal of increasing the participation and success of individuals with disabilities in computing fields. It is a joint project with the Allen School, Information School, and the DO-IT center.  To date, it has served more than one thousand students across the United States providing professional development, peer mentoring, industry and research internships, and funding for travel to conferences.  With its 65+ academic, organizational, and industry partners, it has also focused on institutional change, influencing computing departments, organizations, and companies to make sure they are welcoming and accessible to people with disabilities.

Rethinking Mobility Technology for Children with Disabilities

Early in her research career, Heather began challenging her colleagues in rehabilitation medicine and rehabilitation engineering to envision a paradigm shift in how pediatric mobility technology is conceptualized, designed, and implemented for children with disabilities and their families. Drawing on her background in Disability Studies, which examines how the construct of disability is understood in society across multiple contexts, this work underscores the barriers and facilitators of participation for children who use mobility technology. It provides a roadmap for clinicians, engineers, and caregivers to advocate for policy change, improve pediatric mobility technology design, and understand how historical perceptions of disability and assistive technology often serve to perpetuate exclusion and discrimination of children despite legislation protecting individuals’ rights to mobility and technology.

Go Baby Go

A multidisciplinary, grassroots movement of research, education, and community outreach that involves making safety and accessibility modifications to off-the-shelf, battery powered toy ride-on cars so they are accessible to young children with disabilities as an early form of self-initiated mobility and social exploration. Heather has started two Go Baby Go Chapters in Chicago, IL and Seattle, WA, has modified over 500 cars at no cost for children with disabilities and their families as well as rehabilitation clinics across the country, and has taught over 20 workshops and continuing education courses about multidisciplinary collaboration and innovation to reduce mobility disparities in children with disabilities. Heather continues to do Go Baby Go research and outreach, and together with her Seattle chapter co-founder and fellow UW colleague, she is currently re-launching the chapter as a UW Department of Rehabilitation Medicine supported program.

Expanding voice-based interaction

Over the past few years, conversational voice assistants (VAs) such as Amazon Alexa and Google Assistant have become ubiquitous. We have shown that VAs offer tremendous potential to support equal access to information, particularly for blind and low vision users: they are inherently accessible regardless of vision level and, as novice tools, they offer an approachable introduction to audio-based interaction for people unfamiliar with screen readers. However, VAs currently support only a limited set of tasks. In collaboration with researchers at Microsoft, we are investigating how to combine the strengths of screen readers–powerful expert tools–with the approachability of VA interaction. An example is our VERSE web search tool.

Real-time captioning and sound awareness support

With advances in wearable computing and machine learning, Jon Froehlich and I have been investigating new opportunities for real-time captioning and sound awareness support for people who are Deaf and Hard of Hearing (DHH). Our work spans three primary areas: real-time captioning in augmented reality and wearables (ARCaptions), sound awareness support in the “smart home” (HomeSound), and real-time sound identification on smart watches (SoundWatch, website forthcoming). Throughout this work, we’ve engaged with over 250 DHH participants to help identify design opportunities, pain points, and to solicit feedback on our designs.

Large-Scale Android Accessibility Analyses

Fogarty’s research group is leading the largest-known open analyses of the accessibility of Android apps, thus providing new understanding of the current state of mobile accessibility and new insights into factors in the ecosystem that contribute to accessibility failures (ASSETS 2017, ASSETS 2018, TACCESS 2020). For example, our analyses found that 45% of apps are missing screenreader labels for more than 90% of their image-based buttons, leaving much of the functionality of those apps inaccessible to many people. Such results also highlight that pervasive accessibility failures require continued research and new approaches to addressing contributing factors in the technology ecosystem. Our analyses of common failure scenarios has directly led to Google improvements in the accessibility ecosystem (e.g., corrections to Android documentation code snippets that were inaccessible, thus creating many accessibility failures as such snippets were used in apps) and motivated additional research (e.g., our ongoing work on developer tools that better scaffold developer learning about how to correctly apply accessibility metadata).

Runtime Mobile Accessibility Repair and Enhancement

Fogarty’s research group is developing new techniques for runtime repair and enhancement of mobile accessibility. Key to these approaches is a new ability to support third-party runtime enhancements within Android’s security model and without requiring modification to apps (CHI 2017, UIST 2018). We have applied these approaches to accessibility repair (e.g., techniques to allow social annotation of apps with missing screenreader data), but also to enable entirely new forms of tactile accessibility enhancements (ASSETS 2018). These techniques therefore provide a research basis for both improving current accessibility and exploring new forms of future accessibility enhancements.
