Common non-invasive Brain Computer Interfaces often require distracting sensory stimulation. Using a new technique called Rapid Invisible Frequency Tagging, we show that users can control a brain computer interface without perceiving any stimulation. It is fast, computationally lightweight and requires only 7 MEG sensors, which is a potential application for OPMs.
