Interaction Intention 4

The dataset focuses on four interaction intention states: non-specific intention (NSI), information browsing intention (IBI), active retrieval intention (ARI), and passive retrieval intention (PRI).The dataset provides two main types of processed features.

For EEG signals, phase-locking value (PLV) features are provided to characterize functional connectivity patterns across different frequency bands, including Delta, Theta, Alpha, and Beta. For eye-tracking signals, a comprehensive set of eye-movement features is provided, covering fixation-, saccade-, blink-, and ROI-related measures.Interaction Intentions 4 can be used for multimodal intention decoding, feature-level analysis, cross-subject classification, subject adaptation, and the development of adaptive human-computer interaction systems.
