Summary
This poster paper investigates the feasibility of using commercially available web-based brain-training software as an affordable alternative to expensive specialized stroke rehabilitation software. The researchers observed and interviewed six stroke survivors at the Cabrillo College Stroke and Disability Learning Center who were using various rehabilitation applications on Windows XP computers and iPads. They found that most of the software these students were using was outdated and had numerous design and usability issues — for example, one Windows app required users to erase their previous answer before entering a new one, and an iOS app was designed for therapists rather than for patient self-use. Based on these observations, the researchers compiled six informal design guidelines for brain-training software targeting stroke survivors. They then built a low-fidelity prototype of a web-based brain-training system with four workout categories (Arithmetic, Memory, Name Match, and Spelling) and tested it with three stroke survivors and two individuals with cognitive impairments to validate and refine the guidelines.
Key findings
The study produced six design guidelines for cognitive rehabilitation software: (G1) interfaces should be easy to use and understand at first glance with no distracting images or sounds; (G2) activities should get progressively harder to support skill rebuilding; (G3) instructions should be clear and easy to understand; (G4) activities should have a timer but no time limit, allowing users to track progress without pressure; (G5) the system should be self-guided, letting users choose which cognitive skills to work on; and (G6) users should be able to see records of their work and progress. Testing the prototype validated these guidelines and revealed additional needs, including the potential for community involvement through competitive scoreboards to increase motivation and engagement. Most participants needed guidance selecting appropriate software for their specific rehabilitation goals (speech, memory, reasoning), suggesting that recommendation or assessment features would be valuable.
Relevance
This research addresses a practical gap in cognitive accessibility: stroke survivors need affordable, accessible tools for cognitive rehabilitation, but existing commercial brain-training software is rarely designed with their needs in mind. The guidelines produced are straightforward and applicable beyond stroke rehabilitation to any software designed for users with cognitive impairments — progressive difficulty, no time pressure, self-directed navigation, clear instructions, and progress tracking. For accessibility practitioners and developers, the paper reinforces that mainstream software cannot simply be repurposed for rehabilitation without careful attention to the specific needs and limitations of the target users. The study is limited by its small sample size and low-fidelity prototype, but it provides a useful starting point for more accessible cognitive training tools.
