M. Tech. Electrical Engineering / For the last 3 decades, interdisciplinary studies on the Brain Computer Interface (BCI) have grown in number. This common interest has been stirred up by recent developments in technology and opportunities seen in BCI. BCI systems provide an interface for communicating and controlling the physical environment, bypassing the normal neuromuscular pathways. They thus constitute an alternative means of control for the large population of people with limited to non-existent muscular abilities. Limitations in existing systems have prevented BCIs from being used in real life applications. New approaches are now being investigated with the aim of exporting BCI to home usage. This study investigates a BCI with realistic performances for practical home usage. It proposes a BCI to be used as a modality in a multimodal control of an exoskeleton.
