Evidence build-up facilitates on-line adaptivity in dynamic environments: example of the BCI P300-speller

Fast online adaptivity with policy gradient: example of the BCI "P300"-speller

سنجش عملکرد سامانه‌های رابط مغز و رایانه P300 Speller به‌ازای ماتریس نمایش ردیف و یا ستون (RCP) و نمایش حروف زبان فارسی

As a Brain computer interface system, BCI P300 Speller tries to help disabled people and patients to regain some of their lost ability with allowing communication via typing. The ability of personalization is one of the most important features in a BCI system, so the typing language as a personalization factor is an important feature in a BCI speller. Most prior researches on P300 Speller has f...

Online Detection of P300 and Error Potentials in a BCI Speller

Error potentials (ErrPs), that is, alterations of the EEG traces related to the subject perception of erroneous responses, have been suggested to be an elegant way to recognize misinterpreted commands in brain-computer interface (BCI) systems. We implemented a P300-based BCI speller that uses a genetic algorithm (GA) to detect P300s, and added an automatic error-correction system (ECS) based on...

Development of a Brain Computer Interface (BCI) Speller System Based on SSVEP Signals

BCI is one of the most intriguing technologies among other HCI systems, mostly because of its capability of recording brain activities. Spelling BCIs, which help paralyzed people to maintain communication, are one of the striking topics in the field of BCI. In this scientific a spelling BCI system with high transfer rate and accuracy that uses SSVEP signals is proposed.In addition, we suggested...

ERPs contributing to classification in the ”P300” BCI

Brain Computer Interfaces (BCI) provide a non-muscular communication channel for people with severe motor impairment. The most commonly used BCI for communication is the so called P300-Speller that received its name from the event-related potential (ERP) P300 which is elicited by the speller (oddball) paradigm. Several researchers reported that it is not only the P300 but also other ERPs that a...
