CyberSightings is a regular feature in CYBER that covers the news relevant to the Cyberpsychology community, including scientific breakthroughs, latest devices, conferences, book reviews, and general announcements of interest to researchers and clinicians. We welcome input for inclusion in this column. A brain-computer interface (BCI) is a particular type of human-computer interaction device that allows a direct communication pathway to be established between a brain (or other functional parts of the central nervous systems) and an external object (i.e., a computing device). In classic BCI systems, also classified as unidirectional, the flow of information originating from the brain is used to operate a computer. In the context of biomedical engineering and neuroengineering, BCI systems have been effectively applied to support individuals with motor disabilities. In these assistive systems, electroencephalogram (EEG) signals are recorded from the user's scalp and translated into actions that allow the disabled individual to actuate several operations, such as selecting a letter from a spelling matrix or driving a wheelchair. Further promising applications in the domain of domotic and ambient assisted living are currently under investigation.
