Blue eyes technology uses Bluetooth and eye movement tracking to enable wireless communication and information gathering. It aims to build machines that can understand emotions, listen, talk, and interact with humans by verifying identity and sensing presence. The technology utilizes expression glasses with an eye movement sensor and conductive jacket to track body signals. It can be used in applications like emotional mice and magic pointing through a central processing unit. While enabling human-machine interaction, it also faces challenges in accuracy and sensor limitations.
