Abstract
Despite advances in Assistive Technologies, people with severe motor impairments still face barriers to digital communication. Non-invasive BCIs offer a promising solution, but usability, setup complexity, and gel-based EEG caps limit integration. Dry and semi-dry systems improve comfort and portability, yet fixed montages may be suboptimal. This study uses oddball EEG data to compare two montages and assess the effect of electrode positioning on classification performance. Results quantify the impact of montage on decoding and improve BCI design for assistive applicationsI documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
