Earphone Brain Wave Sensor Music Playback Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current information processing systems lack an effective method to dynamically adjust music playback based on a user's brain wave state, failing to provide personalized audio experiences that enhance cognitive or relaxation states.
Innovation Solution
An information processing system comprising an earphone device with brain wave sensors and a terminal device that measure and analyze brain waves, controlling music playback to align with desired brain wave states, using a music delivery server to provide tailored music playlists for specific brain wave conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If music playback is controlled based on brain wave state measurement, then the effectiveness of inducing desired brain wave states is improved, but the device complexity increases due to integration of brain wave sensors and control systems
Solution Approach 1:
The patent combines brain wave sensors, music playback functionality, and control systems into an integrated earphone device. The brain wave sensors are embedded in the earphone structure, and the control unit is integrated within the same device, merging multiple functions into a single portable unit that can measure brain waves and automatically adjust music playback accordingly.
Solution Approach 2:
The earphone device serves multiple functions: it acts as a music player, a brain wave measurement device, and a control system simultaneously. The same device that plays music also measures the user's brain wave state and adjusts the playback based on the measured state, making the device universal and reducing the need for separate equipment.
2Ease of operation
If brain wave sensors are integrated into earphone device, then the portability and user experience are improved, but the manufacturing precision requirements increase
Solution Approach 1:
The brain wave sensors are nested within the earphone device structure. The sensors are embedded in the earpad or housing of the earphone, utilizing the existing form factor of the earphone to accommodate the measurement components without requiring separate external equipment.
3Adaptability or versatility
If music playback is dynamically adjusted based on real-time brain wave measurement, then the personalization of audio experience is improved, but the processing power and energy consumption increase
Solution Approach 1:
The control unit processes brain wave signals to determine the user's current state and adjusts music playback parameters accordingly. The system selectively modifies playback based on detected brain wave patterns, applying processing only when state changes are detected rather than continuously adjusting all parameters at maximum intensity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system effectively transitions or maintains the user's brain wave state, enhancing concentration, relaxation, or other desired cognitive conditions through personalized music selection and playback control.
Implementation Method 1
a receiver that receives a specification of a desired brain wave state of a user
Data Source
AI summary
An information processing device includes a receiver that receives a specification of a desired brain wave state of a user, and a controller that controls playback of music causing a brain wave state of the user to transition to or maintain the desired brain wave state.
