The PC Control With Eye Movement project functions by combining computer vision with physical eyewear prototypes to translate human eye gestures into computer commands. The system utilizes a specialized pair of prototype eyeglasses equipped with mounted eye sensors and a dedicated light source. As the user moves their eyes or blinks, the light source illuminates the eye area, allowing the sensors or a small camera setup to capture these micro-movements. The hardware connects to a PC or laptop running a custom computer vision script built with OpenCV. This software continuously analyzes the video feed or sensor data in real time, detecting shifts in gaze direction or specific blink patterns. Once the script interprets a designated eye movement—such as looking left, right, up, down, or blinking—it translates that visual input into corresponding mouse or keyboard events on the computer operating system. This allows the user to navigate the desktop, select items, and interact with software applications completely hands-free.

Frequently Asked Questions
You will need a lightweight light source and eye sensors (or a compact camera setup) securely mounted to a prototype pair of eyeglasses, wired to your PC or laptop.
The software requirement specifies OpenCV and a custom computer vision script, which are most commonly implemented using Python or C++.
While it falls under an AI/ML platform category, basic OpenCV scripts can rely on traditional image processing techniques like thresholding and contour detection, though machine learning classifiers can be integrated for advanced eye-tracking.
