Vigilance
How it holds over long monitoring periods.
SPARK · Cognitive Safety · Critical workstations
In a control room, on a monitoring post or at a machine, attention has to hold over long hours, often for an event that rarely happens. SPARK measures vigilance, load and fatigue during the shift.
How it holds over long monitoring periods.
When alarms, tasks and decisions pile up.
Across a shift, a night, a rotation.
Shift patterns, workstation design and training are usually decided without a measurement of the operator's state. SPARK adds it.
In training and simulation, each operator sees their own state during a scenario and learns to manage it.
The operator, measured as precisely as the process.
The sensor is worn during a shift or a training scenario. The measurement is aligned on the events of the task and read in the debrief.
An operator monitors a process through the night, with few events to handle.
Vigilance drops in the early hours; in a training scenario, an alarm then arrives while load is already high.
The site reviews the organisation of the shift and trains its operators on that scenario.
Both are possible, during a shift or a training scenario, as agreed with the organisation.
The operator and the people in charge of training, under the rules agreed with the organisation.
