Story What if a person who cannot speak could still express basic needs using only eye blinks? In this project, we explore the world of Human-Computer Interaction (HCI) and Brain-Computer Interface (BCI) by creating a system that translates eye blinks into spoken words.Mind to Words (M2W) is a communication system designed to help ALS patients and individuals with limited voluntary movement interact with their environment. Using the Neuro PlayGround (NPG) Lite—a powerful, wireless bio-potential sensor—we capture tiny electrical signals from the eyes (EOG) to control a speech-assistance application.This is a completely "hands-free" communication tool. By capturing these bio-potential signals, users can hover through a menu of six essential needs—Water, Food, Washroom, Help, Outing, and Television—and select them to be spoken aloud simply by blinking. This low-cost assistive technology provides a vital voice to those who need it most, turning biopotential signals into meaningful human connection
