Solution Overview

Problem

Current noninvasive neural stimulation methods are inadequate in effectively inducing and modifying desirable mental states such as attention, relaxation, and sleep through audio modulation, as they lack precise control over modulation characteristics like rate, phase, and waveform.

Innovation Solution

A processing device receives sensor-input values and corresponding modulation-characteristic values to generate and play audio outputs that modulate audio parameters such as tempo, loudness, and spectral features, aligning with user data and environmental inputs to target specific brain activity patterns.

Solution Approach 1:

The system dynamically adjusts audio modulation characteristics (rate, phase, waveform) in real-time based on sensor feedback and mapping relationships, transforming static audio playback into a dynamic, adaptive neural stimulation system that precisely controls brain wave patterns

Inventive Principle:

Solution Approach 2:

The system establishes a feedback loop where sensor inputs (measuring actual brain state or physiological parameters) are mapped to modulation characteristic values, which then adjust the audio output. This closed-loop control enables precise modulation characteristic control by continuously adapting to the user's neural state
