Summary
This demo paper presents "littleBits go LARGE," a project that adapts littleBits electronic modules — small, magnetic snap-together electronic components designed to simplify electronics for general audiences — to make them more accessible to people with learning disabilities. The work is part of a larger two-year project titled "Interactive sensory objects developed for and by people with learning disabilities," which investigates ways to make museum and heritage sites more exciting and accessible to people with learning disabilities through co-created interactive sensory objects. In workshops, co-researchers with learning disabilities explored the senses through art-based and technology-focused activities, creating interactive objects that relate to cultural understanding and experiences. The researchers adopted littleBits as an accessible introduction to electronics because they require no wiring, soldering, or programming knowledge — components simply snap together with magnets. However, workshops revealed several usability challenges: participants found it difficult to tell input from output sides (the magnets repel when oriented incorrectly but provide no explanation); the modules were physically small and difficult to handle for people with reduced fine motor skills; colour-coding (blue for input, green for output, pink for power) was not intuitive and required memorisation; labels were too small to read; and the function of many modules was unclear from their appearance. To address these issues, the team enlarged the modules (making them physically bigger and easier to handle), added clearer visual indicators of function and direction, and augmented the design to make each module's purpose more obvious and understandable.
Key findings
The project identified five specific usability barriers that littleBits presented for people with learning disabilities: (1) magnetic orientation confusion — modules repel when placed incorrectly but users did not understand why; (2) small physical size — modules were difficult to pick up and manipulate; (3) non-intuitive colour coding — the blue/green/pink system required abstract learning; (4) tiny labels — text was too small to read for many participants; and (5) unclear functionality — it was not obvious what each module did or how it would affect a circuit. The "go LARGE" adaptations addressed these through physical enlargement (making modules easier to handle), enhanced visual design (making functions more self-evident), and clearer input/output indicators. The participatory approach was central — people with learning disabilities served as co-researchers throughout, not just test subjects. They explored different methods of triggering media (clapping, bend sensors, squeeze sensors) and the results were documented through video, photographs, and one-to-one interviews. The project demonstrates that even products marketed as "simple" electronics may present significant barriers for people with learning disabilities, and that making technology accessible to this population requires attention to physical manipulation, cognitive load, and intuitive design beyond what general simplification provides.
Relevance
This paper sits at the intersection of the maker movement, inclusive design, and cultural accessibility. The broader maker and STEM education movements have championed tools like littleBits, Arduino, and Raspberry Pi for democratising technology creation, but people with learning disabilities are frequently excluded from these opportunities. For accessibility practitioners, the paper highlights that "simple" is relative — what is simple for a neurotypical adult may still present significant cognitive and physical barriers for people with learning disabilities. The specific usability barriers identified (abstract colour coding, unclear cause-and-effect relationships, physically small components) are common across many consumer electronics and educational technology products. The co-researcher model, where people with learning disabilities are active partners in design rather than passive recipients, exemplifies best practice in inclusive design. The application context — creating interactive sensory objects for museum and heritage settings — connects to the broader goal of cultural accessibility, ensuring that people with learning disabilities can not only visit museums but actively create and contribute to exhibits. The project also demonstrates the value of tangible, physical computing over screen-based interfaces for this population.
