  • Methods, systems, and non-transitory computer-readable mediums for SSVEP detection optimization
    Patent number: 11934576
    Abstract: In accordance with one embodiment of the present disclosure, a method includes measuring brain activity for a target frequency and a second harmonic frequency based on a default value of display parameters for a plurality of icons, determining whether a strength of the target frequency and the second harmonic frequency are below a threshold level, and modifying one or more display parameters in response to the strength of the target frequency and the second harmonic frequency being below the threshold level.
    Type: Grant
    Filed: January 14, 2022
    Date of Patent: March 19, 2024
    Assignees: TOYOTA MOTOR ENGINEERING & MANUFACTURING NORTH AMERICA, INC., UNIVERSITY OF CONNECTICUT HEALTH CENTER
    Inventors: Insoo Kim, Hossein Hamidi Shishavan, Kia Golzari, Muhamed Farooq, Ercan M. Dede
  • METHODS, SYSTEMS, AND NON-TRANSITORY COMPUTER-READABLE MEDIUMS FOR SSVEP DETECTION
    Publication number: 20230225654
    Abstract: In accordance with one embodiment of the present disclosure, a method includes 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.
