Back to Analogue: Self-Reporting for Parkinson's Disease
summary
An iterative comparison of four electronic prototypes (Bluetooth buttons, NFC cube, micro:bit) and a paper diary finds the paper solution wins for daily symptom tracking: a tailored one-page diary used by seven participants for 49 days yields 98.54% compliance, supports optional retrospective entries, ordinal circle-only answers to offset tremor, and an ink gel pen for easier input. The project ships an open-source encoder, PaperStream, and reports five concrete design implications for Parkinson’s self-reporting.
