APPARATUS AND METHOD FOR IMPLEMENTING P300 COMPONENT-BASED BRAIN-COMPUTER INTERFACE

摘要

An apparatus, system and method for implementing a P300 component-based BCI are provided. The apparatus may include a display unit to display to a user the P300 component-based BCI, which includes a plurality of items to be selected, an item division unit to divide the plurality of items into N subsets according to usage frequencies of respective items, wherein N is an integer larger than 1, wherein a higher usage frequency the item has, a smaller subset the item belongs to, and a flashing unit to cause N items in the BCI to illuminate each time in a desired (and/or predetermined) frequency so as to make the user aware of, or feel, flashing of the respective items, wherein one item may be randomly selected from each of the subsets to constitute the N items.

主权项

1. An apparatus for implementing a P300 component-based brain-computer interface (BCI), comprising:
a display unit configured to display to a user a P300 component-based BCI, which includes a plurality of items to be selected; an item division unit configured to divide the plurality of items into at least two N subsets according to usage frequencies of each of the plurality of items, wherein a higher usage frequency the item has, a smaller subset to which the item belongs; and a flashing unit configured to cause N items in the BCI to illuminate in accordance with a desired frequency in order to cause at least one flashing of the N items, and
the flashing unit configured to randomly select a respective item from each of the N subsets to constitute the N items.
