ABSTRACT
One of the key components of brain–computer interface (BCI) design is the interfacing paradigm. Progress in BCI research and applications significantly depends on a successful paradigm implementation. BCI paradigm requires simple interpretation and ease of use for end users so that electroencephalogram (EEG) data can be mapped to an application, for example, to drive a prosthetic arm or to send a command to operate an external device. Another remarkable use of the BCI system is to set up a communication network with exterior environment. Such actions necessitate the user to disburse voluntary or involuntary mental or control task without making the subject fatigued or tired. To ensure these criteria, the paradigm design should be leveraged to deliver optimal performance. P300 and SSVEP are two paradigms that have gathered large attentions from BCI communities. Over the last decade, advancement of BCI research has experienced successful design of various hybrid BCI systems. This chapter focuses on the issues and challenges involved during the development of BCI paradigm to harness the advantages associated with recently developed BCI paradigms. In addition, importance of paradigms will be highlighted to open up novel BCI applications for future use, which, in turn, might have a great potential to increase the BCI users to a large extent.
