- © 2022 Elsevier Inc. All rights reserved.Brain-computer interfaces, also known as BCIs, are systems that analyze brain signals and translate them into meaningful information in real-time. These interfaces provide an alternative communication channel to manipulate a computer or a robotic device by modulating the neural activity. This chapter describes a general-purpose P300-based BCI developed for selecting different options presented on a computer screen. This system can be used to send instructions to a robot or any other device that accepts high-level commands representing actions or complex sequences of operations. This chapter includes a detailed description of the processing and classification stages of this BCI, and presents the results obtained from an online evaluation of this interface with 15 healthy participants. The classification accuracy observed in the system evaluation (93.89%) illustrates how computational intelligence and signal processing techniques allow the development of real-time tools for translating brain activity.
