See lessWhat is an example of a BCI communication device?
An example is the P300 speller, which allows users to select letters on a screen by focusing on them, using brainwave responses to flashing letters.

See lessHow do BCIs help individuals with locked-in syndrome communicate?
BCIs enable these individuals to communicate by translating their brain signals into text or speech outputs via computer interfaces.

See lessWhich type of BCI generally provides higher signal quality, invasive or non-invasive?
Invasive BCIs generally provide higher signal quality and resolution than non-invasive BCIs.
Invasive BCIs generally provide higher signal quality and resolution than non-invasive BCIs.
See lessWhat are the benefits of non-invasive BCIs?
Benefits include reduced health risks, lower costs, and easier implementation compared to invasive methods.

See lessWhat is a non-invasive BCI?
A non-invasive BCI uses external sensors, like EEG caps, to detect brain activity without needing surgical implantation.
