Visual FAST is an interactive and intuitive graphical tool for determining the factors that cause fatigue rapidly leading to effective mitigations. This tool, known to many as FAST (Fatigue Avoidance Scheduling Tool), was developed for the US Air Force and was the first computerized application of the SAFTE fatigue model. The graphical portrayal of effectiveness remains a gold standard for assessing the performance effects of sleep deprivation and circadian variation.
Visual FAST Interface
- Is based on more than ten years of experience and unsurpassed for performing root cause analysis of the fatigue factors and cumulative fatigue effects.
- Displays Effectiveness as an intuitive graph of predicted performance highly correlated with the factors that cause fatigue reports.
- Is validated to predict changes in actual worker performance and increases in accident risk.
- Includes a Dashboard displaying fatigue factors at any point in the schedule that are the same as those evaluated by the US National Transportation Safety Board.
- Includes easily edited graphed events to reflect the performance effects of schedule changes or "what if" scenarios.
- The Visual FAST graph can also display other useful metrics, like Sleep Reservoir - a measure of cumulative sleep debt - and Lapse Likelihood - a measure of the chances of a lapse in attention reflective of fatigue.
Dr. Timothy F. Elsmore
Author of FAST
The author of the original FAST software was the behavioral psychologist and pioneer of laboratory computer science Dr. Timothy Elsmore.
Dr. Elsmore's efforts in software development started with implementation of a laboratory control system on the Digital Equipment Corporation PDP8 computer and touch-screen interfaces for studying primate behavior.
Tim's most lasting and influential achievement was authorship of the Fatigue Avoidance Scheduling Tool - FAST. His flair for data presentation and interpretation was skillfully applied to design the graphical portrayal of performance changes in FAST. The original program was written for the US Air Force under a Small Business Innovative Research grant to NTI. He was assisted in that process by Drs. Steven Hursh and Douglas Eddy, but the fundamental design decisions and architecture originated with Tim and they have endured to this day in the version integrated with SAFTE-FAST used by airlines and corporations around the world.
His impact on the science of sleep and performance extend beyond FAST. Dr. Elsmore also wrote the software sold by Ambulatory Monitoring Incorporated to analyze and portray actigraph data, ActionW. Again, his data management and graphic skill set the standard for presentation of activity data.
Tim also pioneered the development of mobile performance assessment with the Palm Pilot-based performance assessment battery, ARES. That system was successfully applied in patients to forecast the onset of migraine headaches and was combined with mobile neural assessment to field assess potential concussive brain injury in football players a decade before it became commonplace.
Tim also developed a laboratory simulation of work and multi-tasking with his programs SynWork & SynWin. This system is sensitive to drugs and sleep deprivation, and permits the investigation of executive function and divided attention.

We thank Tim for his innovations and hard work - his impact on operational fatigue and performance research is broad and enduring. Many thousands of workers enjoy a safer work environment because of the visionary work of Dr. Elsmore.
