EEG-Based Control of a Unidimensional Computer Cursor Using Imagined Body Kinematics
Résumé
Brain computer interface (BCI) are systems that can extract information from brainwaves to control a computer or an external device. A computer cursor controlled by brain activity, one of the interesting neuro-prosthetic devices in BCI, was first offered to the patients with spinal cord injury using invasive measurements of brain activities. More recently, techniques based on noninvasive measurements such as Electroencephalography (EEG) have become popular. Here, we investigate the activation and control of a computer cursor in one dimension by engaging brain signals collected using EEG sensors and through a novel paradigm called " imagined body kinematics. " In contrast to the earlier techniques using sensorimotor rhythms, the method here intends to directly extract information of imagined body kinematics from EEG and thus can significantly reduce training time.
