SSVEP BCI control of a prosthetic hand / robotic manipulator arm.

This is a Brain-Computer Interface (BCI) using Steady State Visual Evoked Potentials (SSVEP) to drive a prosthetic hand attached to a robotic manipulator arm. The stimulus display (black box in front of the robot) contains 9 LEDs that each flash at distinct, constant frequencies. Each LED represents a movement direction for the prosthetic hand (i.e. left, right, up, down, diagonal...) When the user attends to a flashing LED, the SSVEP response according to that frequency is elicited over the occipital regions of the brain. The user's EEG brain signals are then decoded and the robotic arm moves in the corresponding direction. In this particular application, the robotic arm is grasping a dry-erase pen, and the user is spelling the word "g.tec". The bio-signal amplifier (shown on the right) is the g.USBamp amplifier from g.tec. The experimental paradigm, communication and decoding software were developed from the Applied Signal Processing in Engineering and Neuroscience Lab (ASPEN Lab) at Old Dominion University.
