"I can't just Google it": Technology Needs of Adult Braille Learners

Summary
This extended abstract investigates the overlooked challenges and technology needs of sighted adults who learn braille, specifically Teachers of Students with Visual Impairments (TVIs) and parents of blind children. While substantial research exists on braille learning for blind children, very little has examined how sighted adults navigate braille acquisition — a population that learns braille visually rather than tactilely and faces distinct challenges around retention, practice opportunities, and professional application. The author conducted semi-structured interviews with five participants: four TVIs and one parent of a blind child, all of whom learned braille as sighted adults in the United States. Participants had between 3 and 18 years of braille learning experience and had studied Unified English Braille (UEB) and/or Nemeth Code (the braille code for mathematics and science). The interviews explored their overall learning experiences, resources and strategies used, challenges encountered, and technology usage. The study used thematic analysis to identify patterns across the five interviews, revealing three major themes: difficulty with braille contractions and rules, insufficient exposure and reinforcement for retention, and limitations in existing braille learning tools.
Key findings
All participants found Grade 2 braille contractions and rules particularly difficult to memorize, describing them as "weird," "not intuitive," and "confusing." The large number of contractions and the context-dependent rules governing their application created a significant cognitive burden. Even when participants were taught the principles behind rules, they tended to forget the reasoning over time. Participants reported that insufficient exposure to braille — compared to blind children who encounter it constantly — led to gradual skill decay. TVIs typically only use braille during work, and without regular practice, they forget contractions and revert toward Grade 1 (uncontracted) braille. Multiple participants noted that existing braille learning tools have critical limitations: translation programs are inconsistent across platforms, interactive learning platforms indicate errors without explaining why an answer is wrong, and practice exercises are insufficient in volume. Participants expressed a strong desire for technology that can both identify braille input errors and explain the specific rules or contractions that should be applied, essentially providing the kind of contextual, rule-referenced feedback that a human instructor would give. They envisioned this as a mobile app or chatbot-style tool with gamified practice elements. Additionally, participants highlighted a significant gap in braille resources for math and science (Nemeth Code), where online search tools and even AI assistants like ChatGPT provide inaccurate information.
Relevance
This study highlights an important gap in accessibility education infrastructure: the people responsible for teaching braille to blind children often lack adequate tools and support for their own braille proficiency. The finding that TVIs' braille skills decay without regular practice has direct implications for the quality of braille instruction blind students receive. The paper identifies concrete design opportunities for technology developers — particularly mobile applications that provide explanatory error feedback referencing specific UEB rules, gamified practice for retention, and searchable digital resources for Nemeth Code. The observation that mainstream AI tools like ChatGPT cannot accurately handle braille queries (confusing 6-dot and 8-dot systems) underscores a broader gap in how assistive technology knowledge is represented in large language models. For accessibility practitioners, this research reframes braille literacy as a broader ecosystem challenge: supporting not just blind readers but the sighted educators and family members who facilitate braille learning. Though limited by its small sample size of five participants, the qualitative insights point to an underserved user group with clear, actionable technology needs.
