Part-financed by the European Regional Development Fund III. Future challenges and the work to be done  As can be seen, the Emotiv sensor could be used for developing applications to assist disabled and elderly people.  Based on Emotiv sensor, we have developed a head movement based control of an intelligent wheelchair in an indoor environment.  We will present our experimental results on facial gestures based control of an intelligent wheelchair in an indoor environment during next project meeting. 11
