Cognitive load
Phase by phase, as information and decisions pile up.
SPARK · Cognitive Safety · Defence
In a mission, the operator processes a flow of information, decides fast and holds over long hours. SPARK measures the cognitive load, attention and fatigue that go with it, in exercises and simulations, aligned on the course of the exercise.
Phase by phase, as information and decisions pile up.
How it is shared between tasks, and where it narrows.
Over long exercises and successive rotations.
Exercises are debriefed on what was done. The measurement adds what it cost the operator, moment by moment.
Repeated over exercises, it shows how each operator handles load and how that changes with training.
The operator's load, on the same timeline as the mission.
The sensor is worn during exercises and simulations. The measurement is aligned on the course of the exercise and read in the debrief.
An operator goes through a demanding simulation exercise, with information arriving fast.
Load peaks when several sources arrive at once, and attention narrows on one of them.
In the debrief, the instructor works on how attention is shared between tasks.
The use described here is training: exercises and simulations, debriefed afterwards.
Cognitive load, attention and fatigue, phase by phase, aligned on the course of the exercise.
Training centres, simulation units, instructors and human factors teams.
Aviation, industry, driving and critical systems: understanding overload and drops in vigilance.
Emergency vehicles and transport: the driver's load and fatigue across the shift.
The learner and the driver measured under load, for driving schools and road safety.
Control rooms and critical workstations: vigilance and load measured during the shift.
