Possible 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 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 ...

15 صفحه اولP300 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...
متن کاملPolyMorph: A P300 Polymorphic Speller
P300 is an electric signal emitted by brain about 300 milliseconds after a rare, but relevant-for-the-user event. Even if it is hard to identify and it provides a low-rate communication channel, it raises the interest of the scientific community because it can be used in cases in which other evoked potentials fail. One of the applications of this signal is a speller that enables subjects who lo...
