Abstract: This paper presents the review on eye blink detection methods used for the purpose of physically challenged or people suffering from ALS, epilepsy like disease. Brain Computer Interface (BCI) is a methodology which bridges a way for communication with the objects using brain thoughts. This paper will introduce to the other methods of eye blink detection and also to the NeuroskyMindwave which is a revolutionary product to detect Electroencephalogram signal (EEG) which also detects blink of an eye. It gives a glimpse upon the limitations of previous approaches and advantages of proposed product. At the end it will also address the future work which we are doing using this hardware for people suffering from ALS and epilepsy.

Keywords : Neurosky, Mindwave, EEG, eye blinks.
