Summary
This short paper evaluates the Nintendo Wii remote as an alternative web navigation device for people with cerebral palsy, compared to a standard wireless mouse. Despite the abundance of accessibility tools, customizable and inexpensive options for people with motor impairments remain limited, particularly given the wide spectrum of abilities among people with cerebral palsy. The Wii remote connects to a laptop via Bluetooth and can be reprogrammed using freely available software to map any keyboard function to its buttons, motion sensing, and directional pad. Two configurations were tested: Configuration 1 used motion sensing for cursor movement with the directional pad for scrolling, while Configuration 2 used the directional pad for cursor movement with scrolling mapped to buttons. The B-button on the back was disabled in both configurations after pilot testing showed it was frequently pressed accidentally. IBM accessibilityWorks software was also used alongside both devices to provide features like text enlargement and large cursors. Twelve participants (5 male, 7 female) with cerebral palsy completed three web tasks on Facebook, Amazon, and Fandango. Eleven were wheelchair users, most had some visual impairment, and all had prior computer and web experience using a mouse.
Key findings
Six of the nine participants who completed the study showed improved task times using the Wii remote compared to the standard wireless mouse. The tasks covered key aspects of web browsing including social media interaction (Facebook), e-commerce navigation (Amazon), and information search (Fandango). The two configuration options provided flexibility for participants to choose based on their individual motor abilities — an important consideration given the heterogeneity of cerebral palsy. The Wii remote's multiple input modalities (motion sensing, directional pad, numerous buttons) offer more customization possibilities than a standard mouse, and its form factor — designed to be held in one hand — may be easier to grip and control for some users with motor impairments. The use of freely available customization software means the solution is cost-effective and accessible to a broad user base. The study demonstrates that consumer gaming hardware can be repurposed as assistive technology without specialized or expensive equipment.
Relevance
This paper illustrates the potential of repurposing mainstream consumer gaming devices as affordable assistive technology — a concept that remains highly relevant as game controllers continue to evolve with increasingly sophisticated input capabilities (e.g., adaptive controllers from Microsoft and Sony). For accessibility practitioners, the key takeaway is that the wide spectrum of motor abilities within cerebral palsy demands customizable solutions rather than one-size-fits-all input devices. The ability to offer multiple control configurations from a single device addresses this need. The study also highlights the practical reality that many people with motor impairments use standard mice despite suboptimal ergonomics, simply because affordable alternatives are scarce. While the Wii remote is now dated hardware, the principle of leveraging consumer gaming peripherals with customizable button mapping for accessible computer interaction has been validated by subsequent developments like the Xbox Adaptive Controller and PlayStation Access controller.
