Abstract: Intention recognition has received extensive attention in the field of Human-Computer Interaction (HCI). Traditional HCI intention recognition methods rely solely on an electroencephalogram (EEG) or eye movement data without making full use of the advantages of the two methods. This paper proposes an HCI intention recognition method that fuses EEG and eye movement data. It collects EEG and eye movement signals for feature extraction and inputs them into the network of machine learning and pattern recognition for intent recognition. Based on the Dempster-Shafer(D-S) evidence theory, the fusion of the decision layer is performed to obtain the final recognition result. In this study, 20 effective subjects are recruited for interactive intention recognition experiments. Results show that the recognition accuracy of the HCI intention recognition method based on EEG and eye movement signals is higher than that of traditional methods. Therefore, it can provide theoretical and technical support for the adaptive design of the HCI interface in aircraft and weapon equipment systems.

Key words: EEG, eye movement, intention recognition, human-computer interaction, data fusion
