Solution Overview

Problem

Existing audio stream playback technologies lack the ability to dynamically adjust the energy level, such as tempo, in real-time based on user preferences, particularly in social settings like parties, which can affect the mood and experience of attendees.

Innovation Solution

A method and electronic device system that allows users to adjust the energy level of an audio stream by sending instructions to a computer server, which manipulates the tempo of the audio stream based on user-selected preferences, such as mood options, and communicates the adjusted stream back to the device for playback.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the audio stream playback system maintains fixed energy level, then the system complexity is low, but the adaptability to user preferences and social atmosphere is poor

Engineering Contradiction:

Improveadaptability to user preferencesVSAvoidsystem complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements dynamic energy level adjustment by allowing the playback system to change the tempo and energy characteristics of audio streams in real-time based on user selections. The system transitions from static playback to dynamic adaptation where the energy level parameter can be modified during playback according to user preferences representing different social atmospheres.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system changes the energy level parameter of the audio stream to adapt to different user preferences. By modifying temporal parameters such as tempo and rhythm characteristics, the system provides different energy levels that match various social atmospheres while maintaining the same audio content.

Inventive Principle:

Principle #35Parameter changes

2Ease of operation

If real-time energy level adjustment is implemented, then the user experience at social gatherings is improved, but the processing time and computational resources increase

Engineering Contradiction:

Improveuser experienceVSAvoidprocessing time

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The system performs preliminary analysis of the audio stream to identify tempo markers and rhythmic patterns before real-time adjustment is needed. By pre-processing the audio data to extract temporal characteristics and energy level parameters, the system reduces the computational burden during actual playback adjustment, enabling faster real-time responses to user preferences.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system implements feedback mechanisms where user selections about desired social atmosphere are continuously monitored and used to adjust the energy level in real-time. The system receives feedback from the user about the current social context and dynamically modifies the playback characteristics accordingly, creating an adaptive loop that improves user experience.

Inventive Principle:

Principle #23Feedback

AI summary

This disclosure concerns the playback of audio, e.g. in the form of music. More particularly, the disclosure concerns the playback of streamed audio. In one example embodiment, there is a method of operating an electronic device for playback of an audio stream. While an audio stream is being played, for example at a user interface of the electronic device, a first request to adjust an energy level (e.g., a tempo) of the played audio stream is received. In response to receiving the first request, the energy level (e.g., the tempo) of the played audio stream is adjusted.
