Abstract: This paper proposes and creates a new generalised view towards BCI with its related application and recent challenges that can notice through the field of application of BCI e.g. designing the new local neural classifier for the recognition of mental tasks from on-line spontaneous EEG signals. The classifier may be embedded in a portable brain-computer interface called ABI, which has been evaluated with young healthy normal persons. Subject’s performance is analyzed off-line and also online with the presence of proper bio feedback. Correct recognition is the challenge; modest rate is largely compensated by few properties of BCI wrong responses, and its decisions making ability with time factor. In this the subject and his/her personal ability and mental strength learn simultaneously from each other. Sometimes subject grasps it rapidly and so one of the subjects achieved excellent control over the system but few facing problems. Training to each subject is having a complex ...

This paper describes a research approach as well as BCI-based applications with various advancements that are useful for recognition of EEG signal patterns and to assist development of a brain–computer interface (BCI) based on recognition of subject-specific EEG patterns. It also reports the various methods that are used in recognition system. There are various types of componenets used in recognition of EEG signals that are recorded from sensory motor areas during mental imagination of specific task then classified online and used for cursor control. Different methods have been evaluated today for EEG feature extraction and classification that aims to develop methods of analysis, recognition of epileptic EEG signals and the identification of different categories of MI (Motor Imagery) task. This review can be helpful to provide clinical information of patients having epilepsy, Neurological disorders, mental or physical problems. In BCI, if the MI tasks are reliably distinguished thr...
