A 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 کاملAdaptive 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 کاملAccuracy of a P300 Speller for different conditions: A comparison
When using a Brain-Computer Interface (BCI) as a spelling device, the P300-based BCI is mostly common, because of its high speed and accuracy, compared to other BCI paradigms. During the last years many studies have been performed to optimize the single spelling parameters, the stimulation frequency and stimulation intensity. Also different options for the electrode position and classification ...
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...
