Area of Science:

Neuroscience
Human-Computer Interaction
Psychology

Background:

Understanding consumer decision-making is crucial for product design.
Emotions and personality traits significantly influence consumer choices.
Electroencephalography (EEG) offers insights into cognitive and emotional states.

Purpose of the Study:

To profile discrete emotions using machine learning on EEG data from video game stimuli.
To identify personality traits influencing video game perception.
To enhance product design through psychological insights.

Main Methods:

Collected EEG signals from players during gameplay across four video game genres.
Cleaned noisy EEG data using a Savitzky-Golay filter.
Selected features using Random Forest and classified emotions with Support Vector Machine, k-Nearest Neighbour, and Gradient Boosted Trees.

Main Results:

Achieved highest emotion classification accuracy of 82.26% with Gradient Boosted Trees.
Successfully classified four discrete emotions: happy, bored, relaxed, and stressed.
Identified that extroversion and neuroticism influence players' video game preferences.

Conclusions:

Machine learning on single-channel EEG data can effectively classify specific emotions during gaming.
Personality traits, particularly extroversion, correlate with preferred video game genres.
Findings provide valuable data for psychologically informed product and game design.
