Data export function

Measurement data can be exported as a CSV file and this allows for deeper analysis.

The Valence-Arousal Analyzer estimates the values of Russell’s “Valence” and “Arousal”, which are two axes from EEG, and can represent emotional changes in two-dimensions.

About Emotional 2-D Model

A two-dimensional model of emotion was proposed by James A Rusell in 1980 as “A circumplex model of affect”. This paper has been cited in over 10,000 other papers and is highly reliable emotion model.

Russell’s model consists of two axes: “Valence” for positive-negative and “Arousal” for active-inactive.

Various emotions related to joy, anger, sorrow, and pleasure are plotted on the two-dimensional plane.
