Video clips below show subjects selected from our study in which visual cue-evoked emotional responses were assessed with EEG, ECG, Audio and other data. Results in these experiments demonstrate the correlation of neural activity patterns with the valence (positive, neutral or negative) of the images presented. In combination with ECG and contextual data, this type of analysis enables Acrovirt to generate virtual emotion libraries that is used to predict responses and preferences in real life situations. 



This next section is dedicated to research findings in our field of industry and please note these articles are third party institution studies.
