Continuous Auditory Feedback of Eye Movements: An Exploratory Study toward Improving Oculomotor Control

Area of Science:

• Neuroscience
• Cognitive Science
• Human-Computer Interaction

Background:

• Individuals possess limited metacognitive awareness of their automatic eye movements.
• Smooth pursuit eye movements (SPEM) are crucial for visual tracking but difficult to consciously control.
• Understanding how to improve eye movement control and perception is vital for various applications.

Purpose of the Study:

• To investigate the impact of real-time auditory feedback on eye movement control and perception.
• To explore the potential of auditory feedback for sensorimotor learning in both tracking and production tasks.
• To assess if continuous sonification of eye movements can enhance oculomotor behavior and intrinsic perception.

Main Methods:

• An exploratory study involving a training protocol over 8 days.
• Utilized a visual paradigm enabling endogenous generation and control of SPEM without a visual target.
• Measured the effects of real-time continuous auditory feedback generated by eye movements during tracking and production tasks.

Main Results:

• Real-time sonification of eye movements demonstrated the capacity to modify oculomotor behavior.
• Auditory feedback was found to reinforce intrinsic oculomotor perception.
• Significant inter-individual differences in response to the feedback were observed.

Conclusions:

• Real-time auditory feedback shows potential for altering eye movement dynamics and improving self-perception.
• The observed inter-individual variability suggests further research is needed to optimize sensorimotor learning strategies.
• Future studies should aim to understand and mitigate factors contributing to these differences for broader application.
