Eye-Tracking Metrics Classify Brain Hemisphere Activity with High Accuracy
Research published on arXiv (2604.23562) indicates that pupil size and the length of fixations can successfully differentiate between activities in the left and right brain hemispheres, attaining an F1 score of 0.894. The left hemisphere is responsible for language and math, whereas the right hemisphere engages in creative endeavors such as drawing and music interpretation. Although eye-tracking can unveil cognitive states, the use of ocular metrics to identify lateralized brain functions has been relatively neglected. The findings imply that these measurements are reliable tools for cognitive assessment and neurorehabilitation. Future studies will build upon this methodology.
