Methods, systems, and non-transitory computer-readable mediums for SSVEP detection

A system comprising:

• a processor;
• an electronic display;
• a brain activity sensor;
• and
• a memory module having machine-readable instructions that, when executed by the processor, cause the processor to perform operations comprising:
• generating a plurality of icons, wherein each icon has a target frequency unique from each other;
• receiving brain activity data based on an epoch;
• generating a reference signal based on the epoch;
• calculating correlation coefficients between the brain activity data and the reference signal, wherein the correlation coefficients are calculated in a window that is within ±0.5 Hz of the target frequencies, including endpoints;
• determining a confidence score based on the correlation coefficients and the epoch;
• and
• determining a selected icon among the plurality of icons based on the correlation coefficients in response to the confidence score surpassing a threshold confidence score.
