“…Many efforts have been devoted to the development of the P300 spelling paradigm. On the one hand various parameters of this paradigm have been studied and optimized such as matrix size (Allison and Pineda, 2003 ), stimulus interval (Sellers et al, 2006 ), stimulus color (Takano et al, 2009 ; Zhang et al, 2021 ), and so on (Xue et al, 2019 ). On the other hand, researches on developing novel P300 spellers have evolved considerably in the past two decades.…”

A brain-computer interface (BCI) is a non-muscular communication technology that provides an information exchange channel for our brains and external devices. During the decades, BCI has made noticeable progress and has been applied in many fields. One of the most traditional BCI applications is the BCI speller. This article primarily discusses the progress of research into P300 BCI spellers and reviews four types of P300 spellers: single-modal P300 spellers, P300 spellers based on multiple brain patterns, P300 spellers with multisensory stimuli, and P300 spellers with multiple intelligent techniques. For each type of P300 speller, we further review several representative P300 spellers, including their design principles, paradigms, algorithms, experimental performance, and corresponding advantages. We particularly emphasized the paradigm design ideas, including the overall layout, individual symbol shapes and stimulus forms. Furthermore, several important issues and research guidance for the P300 speller were identified. We hope that this review can assist researchers in learning the new ideas of these novel P300 spellers and enhance their practical application capability.

“…The most frequent control signal used by BCI spellers is brain activity recorded via electroencephalography (EEG) [ 2 ], as the main advantages of this method are that it captures brain signals in a non-invasive way, with a suitable temporal resolution [ 3 ]. Previous BCI spellers based on EEG have used specific signals, such as event-related potentials (ERPs), steady-state visual evoked potentials (SSVEPs), or sensorimotor rhythms (SMRs) (e.g., Zhang et al [ 4 ], Nakanishi et al [ 5 ], and Cao et al [ 6 ], respectively). The EEG signals most commonly used by BCI spellers are the ERPs, and the present work therefore focuses on this signal.…”

A P300-based speller can be used to control a home automation system via brain activity. Evaluation of the visual stimuli used in a P300-based speller is a common topic in the field of brain–computer interfaces (BCIs). The aim of the present work is to compare, using the usability approach, two types of stimuli that have provided high performance in previous studies. Twelve participants controlled a BCI under two conditions, which varied in terms of the type of stimulus employed: a red famous face surrounded by a white rectangle (RFW) and a range of neutral pictures (NPs). The usability approach included variables related to effectiveness (accuracy and information transfer rate), efficiency (stress and fatigue), and satisfaction (pleasantness and System Usability Scale and Affect Grid questionnaires). The results indicated that there were no significant differences in effectiveness, but the system that used NPs was reported as significantly more pleasant. Hence, since satisfaction variables should also be considered in systems that potential users are likely to employ regularly, the use of different NPs may be a more suitable option than the use of a single RFW for the development of a home automation system based on a visual P300-based speller.

“…Literatürde yer alan bir diğer çalışmada ise Qu ve arkadaşları geliştirdikleri üç boyutlu tek karakter flaşlanması esaslı paradigma ile toplam 12 katılımcıyla yaptıkları çevrimiçi deneylerde ortalama %94 SD elde etmişlerdir (Qu vd., 2018). P300 yazım paradigmalarındaki görsel modülasyonları değerlendiren bir çalışmada (Zhang, Jin, Li, Wang, & Cichocki, 2021), toplam 10 kişi ile çevrimiçi ve çevrimdışı deneyler yapılmıştır. Sonuçlar, çevrimiçi oturumda beyaz çerçevedeki kırmızı yüz paradigmasının mavi çerçevedeki kırmızı yüz paradigmasından ve kırmızı çerçevedeki kırmızı yüz paradigmasından daha yüksek ortalama SD sağladığını göstermiştir.…”

In event-related P300 potential-based Brain Computer Interface (BCI) systems, the main focus of the studies is how different stimulus types affect system performance. In a study, a data set was created using classical two-dimensional row-column flashing-based and proposed three-dimensional column flashing-based paradigms. According to the results obtained, the proposed three-dimensional column flashing shows high performance in terms of classification accuracy of stimulus presentation. However, how this paradigm changes the P300 potential has not been demonstrated. In this study, the effect of both paradigms on the event-related P300 potential is discussed using a wavelet transform-based method in terms of both time and frequency space. According to the results obtained, it was observed that the proposed paradigm activated more frequency bands on the P300 potential. In addition, using the proposed method, higher P300 amplitude was obtained in many channels. As a result, more effective P300 signals are received in stimulus presentation using the proposed paradigm, increasing the BCI system performance.
