A system where live music audio is transmitted to a paired mobile device with more robust processing capabilities, offloading processing from wearable devices to mobile devices and cloud servers, utilizing synchronization applications to monitor timing and generate feedback, thereby overcoming the limitations of wearable devices and enabling real-time movement instructions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If live audio and movement processing is performed on wearable devices, then real-time feedback capability is improved, but computational power and battery life are insufficient
Solution Approach 1:
The patent introduces a mobile device as an intermediary between the wearable device and the processing system. The wearable device captures audio and movement data, transmits it to the mobile device for processing, and receives feedback. This intermediary approach allows the wearable to maintain real-time feedback capability while offloading the heavy computational tasks to the mobile device, resolving the contradiction between real-time processing and limited computational power.
2Productivity
If live audio and movement processing is performed on wearable devices, then real-time feedback capability is improved, but battery life is reduced
Solution Approach 1:
By using the mobile device as an intermediary for processing tasks, the wearable device minimizes its own energy consumption. The mobile device handles the computationally intensive audio and movement analysis, allowing the wearable to operate with lower power requirements while still providing real-time feedback, thus resolving the contradiction between productivity and energy usage.
3Measurement precision
If movement patterns are predetermined and presynchronized with audio, then synchronization accuracy is improved, but adaptability to unknown songs is reduced
Solution Approach 1:
The system performs preliminary processing of audio files to extract beat patterns and tempo information, storing this extracted data for later use. When a song is played, the system retrieves the pre-extracted patterns and synchronizes movements accordingly. This preliminary action allows the system to quickly adapt to unknown songs while maintaining synchronization accuracy, as the heavy pattern extraction work is done in advance rather than in real-time.
Solution Approach 2:
The system dynamically adjusts the synchronization parameters based on the characteristics of each song. Rather than using fixed predetermined patterns, the system extracts and adapts patterns specific to each audio file, allowing it to maintain high synchronization accuracy across diverse and unknown songs. This dynamic approach resolves the contradiction between accuracy and adaptability.

AI summary
A system and method for providing movement indications associated with a first audio information. The system includes an audio input, a storage media, a wearable device, and a processor. The audio input is for receiving the first audio information. The storage media is for storing a plurality of audio informations and a plurality of associated movement patterns. The processor is for matching the first audio information to one of the plurality of audio informations and for returning both a first movement pattern and a first timing information associated with the first audio information. The wearable device has a movement sensor for generating a set of movement measurement that is used for generating a set of movement indications including, at least, a corrective movement indication corresponding to a difference between a movement measurement and the first movement pattern. The wearable can also have a movement indicator for transmitting the set of movement indications.
