The P300-based brain-computer interface (BCI): effects of stimulus rate.
OBJECTIVE Brain-computer interface technology can restore communication and control to people who are severely paralyzed. We have developed a non-invasive BCI based on the P300 event-related potential that uses an 8×9 matrix of 72 items that flash in groups of 6. Stimulus presentation rate (i.e., flash rate) is one of several parameters that could affect the speed and accuracy of performance. W...
متن کاملA P300 event-related potential brain-computer interface (BCI): the effects of matrix size and inter stimulus interval on performance.
We describe a study designed to assess properties of a P300 brain-computer interface (BCI). The BCI presents the user with a matrix containing letters and numbers. The user attends to a character to be communicated and the rows and columns of the matrix briefly intensify. Each time the attended character is intensified it serves as a rare event in an oddball sequence and it elicits a P300 respo...

15 صفحه اولAnalogue P300-based Bci Pointing Device
We present a P300-based system for the twodimensional control of a pointer on a computer screen, inspired by Donchin’s Speller [1]. In our BCI mouse, four unobtrusive rectangles are superimposed on the screen, near its edges, and are used to represent the directions up, right, down and left (Figure 1). The rectangles are flashed in random order at 180 ms intervals. To limit the risk of perceptu...
متن کاملEEG correlates of P300-based brain-computer interface (BCI) performance in people with amyotrophic lateral sclerosis.
The purpose of this study was to identify electroencephalography (EEG) features that correlate with P300-based brain-computer interface (P300 BCI) performance in people with amyotrophic lateral sclerosis (ALS). Twenty people with ALS used a P300 BCI spelling application in copy-spelling mode. Three types of EEG features were found to be good predictors of P300 BCI performance: (1) the root-mean...
