Adaptive training session for a P300 speller brain-computer interface.
With a brain-computer interface (BCI), it is nowadays possible to achieve a direct pathway between the brain and computers thanks to the analysis of some particular brain activities. The detection of even-related potentials, like the P300 in the oddball paradigm exploited in P300-speller, provides a way to create BCIs by assigning several detected ERP to a command. Due to the noise present in t...
متن کاملA Comparison of P300-speller Stimuli Presentation Paradigms for Brain-computer Interface
Brain-Computer Interface (BCI) exploits the ability of human communication and control bypassing the classical neuromuscular communication channels. The BCI system described in this work is P300 speller. Two different paradigms of the P300 speller were proposed for higher accuracy: (i) the Single display (SD) paradigm that flashes each character individually in one stage and (ii) the Region-bas...
متن کاملSensors selection for P300 speller brain computer interface
Brain-computer interfaces (BCI) are communication system that use brain activities to control a device. The BCI studied is based on the P300 speller [1]. A new algorithm to select relevant sensors is proposed: it is based on a previous proposed algorithm [2] used to enhance P300 potentials by spatial filters. Data recorded on three subjects were used to evaluate the proposed selection method: i...
متن کاملP300 Speller with Enhanced Accuracy in Brain Computer Interface
Communication channel connecting the brain to a computer or other electronic devices is nothing but brain computer interface (BCI). The information extraction from brain is a very demanding task. Brain signals are mixed with other signals or noises coming from a finite set of brain activities that overlap in both time and space. Electroencephalogram (EEG) has been the most popular signal that i...
