| Abstract(in English) | Brain-machine interface technology has a possibility to be applied to practical neuroprosthesis for disabled persons. For example, the trajectory decoding of the human elbow and wrist has been already achieved in various studies. However, the accurate prediction for trajectory of finger motion is still a challengeable problem. We subdurally implanted 90 electrocorticogram (ECoG) electrodes on the human sensorimotor cortex and predicted three-dimensional trajectories of the thumb, index and middle fingers base on the ECoG signals using a sparse linear regression. A participant put her right hand on a table palm-down, tapping the table with one of her thumb, index and middle fingers as tasks. The average of Pearson's correlation coefficient and normalized root-mean-square error between the predicted and actual trajectories were 0.83-0.90 and 0.24-0.48, respectively. |
