Summary

This study tested whether a wearable eye-tracking device could help critically ill patients on breathing machines communicate. Thirty ICU patients tried the device, which lets them call for help or answer questions by moving their eyes. The goal was to see if it was safe, easy to use, and could improve communication for people who cannot speak.
