Background:

Brain Computer Interface (BCI) applications are crucial for assisting individuals with paralysis to communicate.
Motor imagery (MI) based BCIs offer a pathway for restoring communication abilities.

Purpose of the Study:

To propose and evaluate a novel motor imagery based BCI speller using the Oct-o-spell paradigm.
To compare synchronous and asynchronous control methods for BCI spellers.
To assess the impact of an intelligent input method, specifically predictive text entry (PTE), on BCI speller performance.

Main Methods:

Development of a novel motor imagery based BCI speller with the Oct-o-spell paradigm.
Implementation of an intelligent input method, including predictive text entry (PTE) mode.
Comparison of synchronous control against previous asynchronous control in an English word spelling experiment.

Main Results:

No significant differences were observed between synchronous and asynchronous control in classification accuracy, information transmission rate (ITR), or letters per minute (LPM).
Accuracy rates exceeding 70% validated the feasibility of both synchronous and asynchronous control strategies.
The predictive text entry (PTE) mode demonstrated superior efficiency compared to the Non-PTE mode.

Conclusions:

Motor imagery-based synchronous control is a feasible protocol for BCI spellers.
The proposed BCI speller with an intelligent input method, particularly PTE, shows promise for improving communication for individuals with paralysis.
