A review of Rapid Serial Visualization Protocol-based BCI

Participants: Fabien Lotte

Rapid serial visual presentation (RSVP) combined with the detection of event related brain responses facilitates the selection of relevant information contained in a stream of images presented rapidly to a human. Event related potentials (ERPs), measured non-invasively with electroencephalography (EEG), can be associated with infrequent target stimuli(images) in groups of images, potentially providing an interface for human-machine symbiosis, where humans can interact and interface with a computer without moving and which may offer faster image sorting than scenarios where humans are expected to physically react when a target image is detected. Certain features of the human visual system impact on the success of the RSVP paradigm. Pre-attentive processing supports the identification of target information  100ms following information presentation. This paper presents a comprehensive review and evaluation of research in the broad field of RSVP-based brain-computer interfaces (BCIs). Applications that use RSVP-based BCIs are classified based on the operation mode whilst protocol design considerations are critiqued. Guidelines for using the RSVP-based BCI paradigms are defined and discussed, with a view to further standardization of methods and experimental evidence gathering to support the use of RSVP-based BCIs in practice. This review in collaboration with Ulster University, UK, was published in Journal of Neural Engineering [13].
