Abstract: Disclosed herein are systems, methods, and computer-readable storage media for improving human learning by providing multi-sensory stimulus. A system narrates a text to a user at a narration pace, while determining a focal point of the user's gaze using both a camera and eye tracking analysis. The system determines a user pace based on a shift in the gaze focal point during narration of the text, then adjusts the narration pace based on the user pace. The adjustment is performed based on a selection of a retention mode and a development mode. The retention mode maintains the narration pace with the user pace for maximal user retention of the text. The development mode increases the narration pace with respect to the user pace for user reading rate acceleration.
