Abstract
This study aims to develop efficient task paradigms for rehabilitation using haptic BCI system. Seven healthy participants performed the five different tasks: active (A), passive (P), motor imagery (MI), passive motor imagery (PMI) and rest (R) mode. During the right hand wrist movement tasks using the haptic device and flash game paradigm, the eventrelated desynchronization and synchronization (ERD/ ERS) on the somatosensory area were obtained during movement period. Machine-learning algorithms were applied to extract significant features. Fisher linear discriminant ratio used to quantify the dissimilarity across the tasks. These results show that the active task is farthest tasks compared to the rest task and the passive, passive motor imagery task and motor imagery task in order. Before the rehabilitation system for brain-damaged subjects, this pilot study helps investigate the efficient paradigm for haptic EEG-based BCI task.
