Finding an Optimal Duty-cycle for a BCI Speller
- In SSVEP BCIs the stimulation frequencies are fixed, but the same cannot be said of duty-cycles. By altering the used duty-cycles the performance and comfortableness of a BCI speller was examined. This study proposes that the most comfortable duty-cycle can often be used without a significant drop in performance, and most of these performance drops can usually be detected prior to the actual spelling. Two different amplification systems were also compared, resulting in no statistically significant difference in performance.
