The ASME-speller: 30-class auditory brain-computer interface speller using stream segregation and the QWERTY layout
Shin'ichiro Kanoh
IntroductionThis study presents the ASME-speller, a novel 30-class auditory brain-computer interface (BCI) speller system that combines auditory stream segregation with the familiar QWERTY keyboard layout to facilitate intuitive and visionfree communication.MethodsIn the ASME-speller, three distinct auditory streams are presented simultaneously, each corresponding to a row on the QWERTY keyboard. The low-, middle-, and high-frequency streams represent the bottom, middle, and top rows, respective
