Single cycle analysis and phase weighting of the SSVEP response allowed standard criterion levels to be set across subjects and improved transfer rates in a four-class Brain Computer Interface system.
Single cycle analysis and phase weighting of SSVEP responses can improve transfer rates in Brain Computer Interface systems.
Single cycle analysis of the Steady State Visual Evoked Potential (SSVEP) response allows use of standard significance tests to determine a subject's gaze. This allows standard criterion levels to be set across all subjects rather than individually by empirical analysis. Furthermore once a subject's gaze has been classified it is possible to extract a notion of expected phase to a SSVEP stimulus. This expected phase value can then be used to augment classification of attention to a four class Brain Computer Interface system improving transfer rates.
Wilson et al. (Wed,) conducted a other in Brain Computer Interface (BCI) users. Single cycle analysis and phase weighting was evaluated on Transfer rates in a four class Brain Computer Interface system. Single cycle analysis and phase weighting of the SSVEP response allowed standard criterion levels to be set across subjects and improved transfer rates in a four-class Brain Computer Interface system.
