Abstract

In this paper, we investigate the effect that mental fatigue during repetitive exercises of a visual P300 Speller has on the P300 component, in terms of accuracy, amplitude, latency, signal morphology, and overall signal quality. This work is part of a larger EEG based project and is based on the P300 speller BCI (oddball) paradigm and the xDAWN algorithm, with eight healthy subjects; while using a non-invasive Brain-Computer Interface (BCI) based on low fidelity electroencephalographic (EEG) equipment. Herein, eight channels through the initial task (6 minutes), additional tasks (50 minutes) and final task (6 minutes) states, recorded the subjects’ signal. Our results show that the accuracy was best for the initial task (IT) at 100%, followed closely by the final task (FT) at 98%. In addition, our ANOVA analysis showed that the amplitude exhibited a statistical significance between IT and FT, while the latency did not indicate any statistical difference. This paper provides initial results into the practicability of the aforementioned P300 speller methodology and low-cost equipment to be used repetitively and continually and the effect thereof on accuracy and signal characteristics. Our aim is to assess the effect of prolonged usage and exposure to the aforementioned methodology and equipment, with the aim of broadening its use in a real-world context.
