Mental fatigue is hard to put into words and easy to underestimate. SPARK measures how it builds over a task, a day or a period, from brain activity and physiology.
The moment vigilance starts to drop.
How fatigue accumulates across a task or a day.
Mental fatigue told apart from physical tiredness, brain and heart read together.
Fatigue is usually described with words and questionnaires. A curve measured in real conditions gives a common reference to the person and to those who follow them.
Followed over time, it shows what tires, what restores, and how that changes.
Fatigue, made visible.
The sensor is worn during the activity. The measurement is read afterwards with the person and the professional who follows them. SPARK makes no diagnosis.
A person is measured over a demanding working day.
Vigilance holds in the morning and starts to drop in the afternoon, before the person feels tired.
With the professional who follows them, the person adjusts breaks and the order of tasks.
No. SPARK makes no diagnosis: it measures, and the professional who follows the person interprets.
Brain activity and heart rhythm are read together, so a mental effort is not mistaken for a physical one.
