15 صفحه اولSemi-Supervised Clustering Approach for P300 based BCI Speller Systems
The paper presents a k-means based semi-supervised clustering approach for recognizing and classifying P300 signals for BCI Speller System. P300 signals are proved to be the most suitable Event Related Potential (ERP) signal, used to develop the BCI systems. Due to non-stationary nature of ERP signals, the wavelet transform is the best analysis tool for extracting informative features from P300...
متن کاملA new hybrid BCI paradigm based on P300 and SSVEP.
BACKGROUND P300 and steady-state visual evoked potential (SSVEP) approaches have been widely used for brain-computer interface (BCI) systems. However, neither of these approaches can work for all subjects. Some groups have reported that a hybrid BCI that combines two or more approaches might provide BCI functionality to more users. Hybrid P300/SSVEP BCIs have only recently been developed and va...
متن کاملPossible Sources of Perceptual Errors in P300-based Speller Paradigm
INTRODUCTION Our ability of detecting or identifying stimuli is limited and we are susceptible to different kinds of illusions or ‘mistakes’. Perceptual limits are often investigated by using rapid serial visual presentation (RSVP) experiments. In a typical RSVP experiment stimuli are sequentially presented at a rate of 6 to 20 items per second and observers are asked to detect or identify a ta...
متن کاملIdentifying informative features for ERP speller systems based on RSVP paradigm
This preliminary study focused on identifying informative features in the frequency and spatial domains for single-trial Event Related Potential (ERP) detection for ERP spelling systems. A predefined sequence of letters was presented to subjects in a Rapid Serial Visual Presentation (RSVP) paradigm. EEG data were collected and analyzed offline. A Linear Discriminant Analysis (LDA) classifier wa...
