Integrating Eye Tracking in Acoustic Research: Methods for Sound Localization, Event Detection, Multimodal Sensing,...

Area of Science:

• Auditory Perception and Human-Environment Interaction
• Multimodal Sensory Integration

Background:

• Eye-tracking technology is increasingly integrated with acoustic research.
• Understanding auditory perception and human behavioral responses is crucial.

Purpose of the Study:

• To review recent developments in eye tracking and acoustics.
• To analyze how eye-movement data aids in interpreting auditory events and spatial listening behaviors.
• To explore multimodal human-environment interactions.

Main Methods:

• Structured literature review of studies at the intersection of eye tracking and acoustics.
• Categorization of reviewed studies into four main research areas.
• Analysis of eye-movement patterns and multimodal data.

Main Results:

• Eye-movement patterns indicate auditory attention and perceptual processes.
• Integration with other sensing modalities (physiological, visual, acoustic) enhances interpretation.
• Advances in real-time processing, machine learning, and sensor fusion improve multimodal analysis.

Conclusions:

• Eye tracking is a valuable tool for acoustic research, offering insights into auditory perception and behavior.
• Standardized protocols and adaptive multimodal frameworks are needed for future research and intelligent systems.
• Further development is required to address limitations like variability and environmental interference.
