Improvement of performance of Japanese P300 speller by using second display

Yamamoto Y., Yoshikawa T., Furuhashi T.

Journal of Artificial Intelligence and Soft Computing Research

2015

Vol. 5, No. 3

221--226

Brain computer interface (BCI) is a system allows a user to control external devices or to communicate with other people using only his or her thoughts. The P300 speller is one such BCI in which users input letters. For inputting letters via the P300 speller, higher accuracy and shorter input times are needed, especially given densely populated display screens. We propose a new interface with a second display in the P300 speller that the user can switch to and from by selecting the “next” or “back” commands, therby reducing the density of displayed letters and improving the performance of the P300 speller. We show the comparison results in terms of accuracy and input times between the conventional interface and proposed interface.
