The present invention relates to a real-time interactive cognitive guidance system and method using a Magnetic-Sync Engine (MSE) that monitors a user's cognitive state in real time and pre-projects a target trajectory to compensate for the delay in the brain's visual information processing. The MSE of the present invention calculates a virtual gravitational force corresponding to the distance between the user's input point and the target trajectory to pull the user toward the target path like a magnet, and forms a cognitive highway by projecting a visual guide 0.1 to 0.2 seconds earlier than the expected point the user will reach through pre-pulling timing control. By fusing multimodal sensors such as eye tracking and tactile input, the cognitive load is precisely calculated, and accordingly, the size of the virtual gravitational force and the shape of the trajectory can be varied in real time. Upon successful synchronization, neurofeedback is provided through solfège frequency audio and blooming animation to maximize learning efficiency, and the invention can be applied to various fields such as medical rehabilitation, cognitive training, and precision work education.
