Morse Code Detector and Decoder using Eye Blinks

Communication with the outside world or the caretakers is one of the major challenges for the people with disabilities. In this work, the authors propose a realtime algorithm to detect morse code from the eye blinks in a series from a live camera. The proposed algorithm detects eye landmarks and estimates the level of eye-opening using eye aspect ratio (EAR). The low-cost software decodes morse code precisely based on the duration of the eyes closed or opened which in turn is translated to English Language. So, this system is intended to provide an alternative form of communication for people with disabilities and to convey confidential messages.
