Hybrid brain computer interface in wheelchair using voice recognition sensors

Brain computer interface is a direct technological interface between a brain and the computer. It is a fast growing emergent technology in which researches try to build a direct channel between a brain and a computer. In this paper we use a Hybrid BCI in order to provide large number of commands with increased accuracy to the BCI user. BCI can serve as powerful aids for severely disabled people in their daily life. This technology is especially used to help the disabled people to move voluntarily. In BCI wheelchair the movement of the wheel chair is going to be controlled by adding voice recognition sensors in order to give an effective result with less effort. The voice and the brain signals when synchronises with each other then it is converted as a movement in the wheelchair by moving it towards left, right, accelerating, decelerating etc,. In this paper we propose a hybrid brain computer ionterface in wheelchair using voice recognition sensors which can be used by physically challenged persons by reducing the effort for high concentration power.
