Today, 1 in 5 persons over the age of 20 will experience a stroke at some point in their lifetime. If a stroke affects one side of the brain, such as the left, the opposing side of the body, such as the right, will become paralyzed. Hemiplegia is the name for this particular form of unilateral paralysis. These people who are paralyzed can see and hear what is going on around them, but they are unable to converse with them since one side of their body will be totally paralyzed. Their capacity to talk will be diminished if the paralysis affects their facial muscles. These patients must be able to communicate their wants and thoughts because they are unable to talk and perform any bodily tasks on the side of their bodies that is injured. Since “Eye-Blink” is an automatic reflex (though it can sometimes be voluntary), the affected individual can effectively blink the eye on the unaffected side. Therefore, in this research, we developed a system that recognizes a wink and speaks out to convey the person's thoughts and desires. This system's advantages include low cost and ease of transportation due to its compact size. It is also taken into account that it causes some discomfort to the patient because they have to blink their eyes constantly when it is necessary to communicate. Flickering is detected by an infrared sensor and each blink counts a word or phrase describing regular activities like eating, sleeping, drinking, etc. will be given as voice over speaker and can also perform an activity (automation).
