Pace-Aware Music Playback Using Runner Stride and Tempo Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional music players lack the ability to dynamically adjust music tempo in real-time based on a runner's pace, terrain, and run profile, leading to suboptimal audio experience during exercise.
Innovation Solution
A music player system incorporating pace tracking circuitry that selects songs and adjusts tempo using data from sensors, positioning circuitry, and run profile data to synchronize audio playback with a runner's pace, employing time-stretching techniques to maintain a consistent stride pace.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional music players play music at fixed tempo, then the music playback is simple and stable, but it cannot synchronize with the runner's pace leading to suboptimal audio experience
Solution Approach 1:
The music player dynamically adjusts music tempo in real-time based on detected runner pace, transforming from a static fixed-tempo system to a dynamic adaptive system that responds to changing exercise conditions
Solution Approach 2:
The system uses sensor data and positioning circuitry to detect runner pace, then feeds this information back to the audio processing circuitry to adjust music tempo, creating a closed-loop feedback system that continuously optimizes synchronization
2Ease of operation
If the music tempo is dynamically adjusted to match runner's pace, then the audio experience is enhanced, but it requires real-time pace detection and tempo control increasing system complexity
Solution Approach 1:
The music player integrates multiple functions including pace detection via sensors, positioning for terrain analysis, run profile management, and dynamic tempo adjustment into a single multi-functional device, reducing the need for separate specialized equipment
Solution Approach 2:
The system automatically detects runner pace and adjusts music tempo without requiring manual intervention, allowing the device to self-regulate and optimize audio playback based on real-time exercise conditions

AI summary
An electronic device may comprise audio processing circuitry, pace tracking circuitry, and positioning circuitry. The pace tracking circuitry may be operable to selects a tempo of songs for playback, by the audio processing circuitry based on position data generated by the positioning circuitry, a desired tempo, and whether the songs are stored locally or network-accessible. The position data may indicate the pace of a runner during a preceding, determined time interval. The pace tracking circuitry may control the song selection and/or time stretching based on a runner profile data stored in memory of the music device. The profile data may include runner's distance-per-stride data. The electronic device may include sensors operable to function as a pedometer. The pace tracking circuitry may update the distance-per-stride data based on the position data and based on data output by the one or more sensors.
