Automatic Correction of Finger Movement on Electroencephalography

Abstract:

An experiment of automatic correction of finger movement was designed. In the experiment, participants were asked to quickly point to a target’s position with right thumbstick controlling a handcursor on a screen and electroencephalography(EEG) signals were recorded as well. The relevant eventralated potenial(ERP) components were analyzed by trials data averaging. The results show that a negativity at 150 ms and a positivity at 320 ms were found in jump trials.

Key words:fingermovement automatic correction; eventrelated potential (ERP); doublestep reaching task; electroencephalography (EEG)
