Measurement of electrical activity : These include Brain, Heart, Muscles.
-
Measurement of eye movements and pupils : Eye movements are determined using Eyetracking technologies, which usually also measure the Pupil diameter in combination.
-
Optical measurement methods : Using NIRS: Infrared spectroscopy the oxygen saturation of the blood can be determined optically.
-
Other procedures : Special procedures can be used to extract Facial expressions and thus the current emotional state of the subject.
BIOSIGNALS
Biosignals are understood as the measurable parameter of the human body over time. Various non-invasive methods are available for research.
