Itchtector: A Wearable-based Mobile System for Managing Itching Conditions
summary
Smartwatch sensors on both wrists record accelerometer and gyroscope traces from 40 participants across a three-phase study, with 7-hour nocturnal sessions validated against infrared video; an autocorrelation-based algorithm extracts periodic scratch patterns and reports about 88% accuracy with precision ~0.8 and recall ~0.75. Server-side weather and national fine-dust data link scratch frequency to external factors; a web dashboard shows time-lined scratch counts and treatment comparisons but the wrist-only band misses lesions beyond the wrist and can irritate skin.
