Tools & Software
Apply the SAFTE model to sleep data.
Language: R
Category: Sleep & Fatigue Modeling
License: Non-commercial research use
Overview
SAFTE-R is a package written for R that applies the Sleep, Activity, Fatigue, and Task Effectiveness (SAFTE) model to previously collected sleep data. The SAFTE model is a biomathematical framework that predicts human cognitive performance based on previous sleep patterns.
Intended use: The SAFTE-R package is intended for use by students, scholars, and scientific researchers as a freely available research tool and is not intended to be used, marketed, or sold as a product or as a service for profit.

Background & Attribution
SAFTE-R is based on the original patented model under expired U.S. Patent No. 6,579,233, System and Method for Evaluating Task Effectiveness Based on Sleep Pattern. SAFTE-R was constructed using original functions and algorithms provided by and under the supervision of SAFTE model inventor Dr. Steven Hursh.
This R package should not be confused with similarly trademarked product names, such as SAFTE (Fatigue Science) or SAFTE-FAST (Institutes for Behavior Resources, Inc.).
Scope & Limitations
SAFTE-R is limited to the use of the original patented SAFTE model equations and does not include features specific to the commercial SAFTE-FAST software:
What SAFTE-R does not include
- Scheduling insights
- Auto-Sleep or automated sleep estimation
- Graphical user interface to interact with the data
- Data importing from scheduling systems
- Batch processing of large data sets
- A mechanism to phase-shift the model resulting from shift work or transmeridian travel
- Does not consider geographic location or light exposure based on location or time of year
- Does not include derived performance metrics or subjective alertness scores
- Does not include any improvements to the original model made since the time of the patent
