What is cognitive load?
The cognitive load is defined as the mental load caused by handling, analyzing, and managing in real time both thinking and external information sensed by the human body. Actually, the cognitive load represents the brain capacity to process efficiently information. High cognitive load can lead to human errors due to a decrease of capabilities to manage critical task-related information. Low cognitive load can lead to poor human performance caused by a disengagement in the main task.
Our solutions for cognitive load monitoring
Phasya offers and develops software modules for measuring the level of cognitive load from the analysis of ocular data (e.g. blinks), cardiac data (e.g. heart rate variability), or the combination of both data. According to the available data and their specifications, our software modules can output the level of cognitive load on a scale up to several levels (from low cognitive load to high cognitive load).
Currently, our software modules for cognitive load monitoring are available in prototype versions for test and evaluation purposes.
Cognitive load measurement from ocular data
This software module for measuring cognitive load (prototype version) is based on the analysis of one or several eye features. This module is adaptive to various specifications of ocular data (resolution and sampling rate).
Cognitive load measurement from cardiac data
This software module for measuring cognitive load (prototype version) is based on the analysis of heart rhythm features such as heart rate variability.
Cognitive load measurement from data fusion
This software module for measuring cognitive load (prototype version) is based on the analysis of ocular data and cardiac data. The combination of ocular and cardiac data enables a better accuracy of the cognitive load measurement.
