Milestone SSVEP EEG Control
No date set
One significant form of EEG-based BCI control which is not currently supported is referred to as Steady-State Visual Evoked Potential (SSVEP):

For SSVEP based control the Brainstorms software will present a set of four checkerboard patterns which correspond to four directions the robot can be instructed to drive (forward, backward, turn left, and turn right). By having the computer display rapidly flash the checkerboard patterns at different frequencies (between 3 and 40 Hz) it is possible to measure the harmonic resonance in the visual cortex (at the back of the head) which matches the specific pattern the user is looking at, and therefore determine the direction they wish to steer.
Such control is envisioned to be easy for the majority of users and require little or no trainting.
This level of control will require access to raw EEG signals as well as implementation of SSVEP algorithms either from scratch or from a third-party Open Source library such as OpenViBE http://openvibe.inria.fr
