摘要： A method for removing artifacts from an electroretinogram, the method comprising: visually stimulating at least one eye of a test subject, and using at least two electrodes to measure electrical responses from the at least one eye of the test subject; recording the electrical responses during, and for a predetermined period of time after, the time at which a visual stimulation is applied, whereby to generate a data set, wherein each electrical response is represented as a sweep comprising a plurality of voltage amplitude values and a plurality of corresponding time values; applying an elevated high pass filter to each sweep, wherein the elevated high pass filter is configured to remove any signal components with a frequency value of

摘要： Biometric information about a person may be collected and analyzed to gain insight into the person's physical and/or emotional conditions. The collection and analysis may be performed using a uniquely designed sensing device that includes multiple sets of sensors configured to collect EEG, EOG, EMG, EDA, and/or PPG signals from the person's head and/or facial areas. The sensing device may include a multi-layered facepad and may be coupled to a VR/AR headset and/or a scalp engagement apparatus to monitor the person's physiological and/or neural reactions to audio/visual stimuli.
