Privacy First. Worker Info Remains Private.
Readi is a privacy-first platform, designed to provide insights regarding on-duty fatigue, while keeping private the data that goes into the model. All personal data concerning sleep, demographics, and survey responses remain private by default.
Machine Learning with 4M+ sleeps
Readi’s Machine Learning model is calibrated based on an anonymized and growing database of 4 million sleeps. These sleeps were recorded by wearables worn by shift workers around the world in industrial environments.
Combined with de-identified data on shift schedules, demographics, and survey responses, these data enable an unparalleled ML engine to predict an individual’s sleep history without requiring the use of wearables. The sleep predictions then serve as an input into our Fatigue Prediction model, SAFTE.
SAFTE™ Biomathematical Fatigue Model
The SAFTE Fatigue Model was developed by the Walter Reed Army Institute of Research at the U.S. Army Medical Research Development Command. It has been extensively validated by the U.S. Department of Transportation, Federal Aviation Administration, and numerous other organizations.
The SAFTE Fatigue Model is exclusively available from Fatigue Science and its affiliates.
Deep Analysis of Cumulative Sleep
We know intuitively that a lack of sleep causes fatigue, but knowing one’s sleep quantity is only one of the many factors necessary in order to create an accurate fatigue prediction.
Accordingly, the SAFTE Fatigue Model accounts for a robust array of relevant sleep factors, including acute sleep interruptions, cumulative sleep debt, and the consistency of sleep onset and wake times, and circadian disruptions that influence a change in cognitive function.
ReadiScore: Hour-by-Hour Fatigue Prediction
The ReadiScore is the SAFTE Model’s output, a prediction of hour-by-hour changes in cognitive effectiveness, reaction time, and lapse likelihood throughout the course of the day or night. Fatigue progresses in a predictable manner, and the SAFTE Model considers not only cumulative sleep history, but also factors such as the internal body-clock and and seasonal light exposure based on one’s general geographic location.
Lab-Validated Predictor of Reaction Time and More
Extensive biomathematical research, including work relied on by the U.S. Dept. of Transportation, has found that ReadiScores reliably indicate human impairment in terms of reaction time and the comparable effects of alcohol.
Real-World Validation: Predict Operator Safety & Performance
The ReadiScore has not only been validated in the lab — it has also been proven in real-world industrial environments as a predictor of operator safety and performance. Seven separate studies are shown here, including many using telematics data.
The studies uniformly affirm that operator safety and performance suffers when one’s ReadiScore indicates high levels of predicted fatigue.
