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 ...

Abstract English orthography differs from that of other European languages in terms complexity and regularity. This difference may impact the development accurate spelling English, especially when it is learned as a foreign language school. In this study we wanted to explore patterns Spanish speaking children learning at To do so, analyzed errors free narrative task 136 fourth, fifth sixth grad...

The P300 is an endogenous event-related potential (ERP) that is naturally elicited by rare and significant external stimuli. P300s are used increasingly frequently in brain–computer interfaces (BCIs) because the users of ERP-based BCIs need no special training. However, P300 waves are hard to detect and, therefore, multiple target stimulus presentations are needed before an interface can make a...

A brain-computer interface (BCI) is a type of technology that establishes communication channel between user and certain devices in the environment via brain signals user. The UMA-BCI Speller tool allows for easy configuration BCI, permitting it to be manipulated without need much technical knowledge. However, adapting BCI system so can communicate with challenging task. simpler increasingly us...
