Enhancing physical activity based on BCI for physically disabled

Abstract

Elderly and disabled people needs proper care at a right time in order to improve their quality of their life. It is appropriate for them to use a mechanical wheel chair but difficult to use by these people. To provide an easy movement, the designing of intelligent wheel chair is required. Using Brain Computer Interface(BCI), brain wave control wheel chair is controlled directly by the brain. The direct communication between brain and wheel chair is enabled by Brain Computer Interface (BCI). The mobility of these persons can be enhanced by using the Electroencephalogram (EEG) signal based movement of the wheel chair. Mindflex P2369 headset is used for capturing the EEG signal. EEG signal is transmitted by headset wirelessly via Bluetooth. Based on the EEG concentration, the direction of wheel chair can be determined using signal processing techniques. Atmega 328 microcontroller is programmed to act as BCI controller. Depending on the brain concentration values, the control commands will be transmitted and based on the human thoughts, the wheel chair will be moved.
