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.
