Episode Summary
Executive Summary: Kurt Colstead recounts how a sudden nerve injury left him with one paralyzed arm and forced him to confront the everyday barriers built into a two-handed world. He describes adapting clothing, shoes, buckles, driving, and writing tools, ultimately creating a customizable one-handed keyboard setup he shared publicly through his Adapt or Design series.
Main Topics: Sudden injury and diagnosis (Priority: 5/5): Kurt explains how he woke in a daze with a paralyzed right arm, went to the hospital, and learned he had severe brachial plexus damage from a presumed cardiac event. Designing around one-handed life (Priority: 5/5): He details practical adaptations for daily living, including moving wallet/phone access, using holsters and slings, and reorganizing how he carries and reaches essentials. Adaptive footwear and buckles (Priority: 4/5): Kurt compares off-the-shelf and DIY shoe solutions, praises hands-free shoes for expressive engineering, and highlights magnetic buckles as a transformative one-handed fastening mechanism. Unexpectedly accessible designs (Priority: 3/5): He notes that some systems, especially driving controls in a U.S. car with a stick-shift background, turned out to be easier than expected with one working hand. Writing one-handed and keyboard research (Priority: 5/5): Because writing is central to his work, he explores speech-to-text and several one-handed keyboards, evaluating tradeoffs in movement, learning curve, and function density. The Curti and sharing solutions (Priority: 5/5): Kurt ultimately custom-programs his existing keyboard into layered modes, shares the setup online as the 'Curti,' and frames the whole project as a resource for others facing similar challenges. Recovery and long-term adaptation (Priority: 4/5): One year later, he describes partial recovery, reduced pain, and ongoing rehabilitation, emphasizing that adaptation is still unfolding and that age affects retraining.
Key Arguments: A severe injury can rapidly turn ordinary design assumptions into barriers, making accessibility a daily, not abstract, concern. Assistive design is most effective when it preserves familiar habits while reducing effort, rather than forcing a complete break from prior muscle memory. Off-the-shelf assistive products can be brilliant, but they may still carry tradeoffs in cost, learning curve, or aesthetics. Magnetic buckles, lock laces, and hands-free shoes show that good assistive design can be both functional and visually clear. Driving can be unexpectedly workable one-handed because vehicle controls distribute tasks in ways that may favor the left hand in U.S. cars. Speech-to-text helps with messages and email, but it cannot fully replace the iterative, highly edited process of professional writing. A modular, software-based keyboard solution can be more useful than buying a dedicated one-handed device because it preserves fallback functionality and can be shared widely. Publicly documenting adaptive solutions helps other disabled users skip some of the trial-and-error and leapfrog directly to effective tools.
Data Points: Hospital stay: 1 week - Kurt stayed in the hospital while doctors investigated the cause of his arm paralysis. Recovery timeline quoted by doctors: Days, weeks, months, sometimes even years - Doctors explained the brachial plexus injury could involve very long recovery and may be permanent. Number of hands affected: 1 working hand - The injury left him navigating daily life with only his left hand functional for much of the recovery period. Keyboard options tested: 3 - He narrowed one-handed keyboard research to three main contenders: Meltron, Tippy, and Half Quirty. Series title: Adapt or Design - Name of Kurt’s article series about adapting to one-handedness and building assistive solutions. Website resource: Free - He made the Curti keyboard setup instructions and files available at no cost on the 99% Invisible website.
Pivotal Quotes: "I had to go from thinking of it in terms of being an injury to thinking of it in terms of being a disability." — Kurt Colstead: He describes the mental shift after learning the nerve damage was likely permanent. "The world is designed for two-handed people first, right-handed people second, and left-handed people last." — Kurt Colstead: His summary of how everyday products and spaces privilege two-handed use. "I think of it as the best of all worlds." — Kurt Colstead: He explains why programming his existing keyboard into layered one-handed modes was his preferred solution.
Implications: The episode shows that accessibility is often solved through flexible, user-driven design, not just specialized products. Sharing adaptable tools and layouts can expand access, reduce friction, and inspire better mainstream design.
