METHOD FOR DETERMINING PREFERENCE, AND DEVICE FOR DETERMINING PREFERENCE USING SAME

摘要

The present invention provides a method for determining preference implemented by a processor, and a device for determining preference using same, the method comprising the steps of: providing image content to a user; receiving electroencephalogram data and gaze data including a series of gaze position data or gaze speed data that is measured while the image content is provided; determining a region of interest of the user with respect to the content on the basis of the gaze data; determining a saccade onset time on the basis of the gaze data; extracting, on the basis of the electroencephalogram data, electroencephalogram data for a time period including the saccade onset time; and determining whether the user prefers the region of interest on the basis of the extracted electroencephalogram data.
