Brain-Computer Interface: Text Reader for Paralyzed Patients

Abstract

Brain-Computer Interface enables interaction between the human brain and the computer (any computing device). This facilitates to create an application and to interact with the surrounding environment. The use of dry electrodes helped to capture brain signals non-invasively and designing application would be easy as it does not involve the preparation of the subject or individual. This paper shows the experience in designing and developing application prototype using BCI framework and brain signals. The application involves capturing of eye events signals which are then used to control the application. Furthermore, Neurosky Mind-wave Headset, which is an electroencephalograph (EEG) recording device available in the market is used to measure brain activity using one strategically placed dry electrode sensor. Brain activity is recorded non-invasively and is sufficient to control the application.
