How EEG is used in BCI?
An electroencephalography (EEG)-based brain-computer interface (BCI) is a system that provides a pathway between the brain and external devices by interpreting EEG. EEG-based BCI applications have initially been developed for medical purposes, with the aim of facilitating the return of patients to normal life.
What types of EEG signals information could be used in a BCI system?
Most EEG-based BCIs use the P300 evoked potential, sensorimotor rhythms (SMRs), or the steady-state visual evoked potential (SSVEP). All three BCI types can help to restore basic communication and control to people with severe neuromuscular disabilities.
What are the three mostly utilized features of EEG signals in BMIS?
Three different types of EEG-based BMI are currently in use namely slow cortical potential (SCP)-BMI, sensorimotor rhythm (SMR)-BMI and P300-BMI.
What is signal processing in BCI?
A Brain Computer Interface (BCI) utilizes signals to establish a connection between a person's state of mind and a computer-based signal processing system, which interprets the signals [1]. BCI provides a direct communicational channel between the brain and an external device without involving any muscular activities.
