Workout Video Playback Speed Control for User-Adaptive Tempo Sync
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Workout videos often have fixed speeds that do not align with individual user abilities, leading to user dropout or injury due to mismatched workout speeds and music tempo, and lack of customizable difficulty levels.
Innovation Solution
An electronic device that identifies workout motion speed and audio tempo to adjust playback speed, ensuring synchronization and user-specific workout intensity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the playback speed of workout video is fixed, then the video content and audio remain synchronized, but the workout speed does not match individual user abilities leading to user dropout or injury
Solution Approach 1:
The patent applies dynamics by making the playback speed adjustable and changeable based on user ability and music tempo. The system dynamically modifies the video playback speed rather than keeping it fixed, allowing the workout video to adapt to different user fitness levels while maintaining coordination with the accompanying music.
Solution Approach 2:
The patent changes the playback speed parameter of the workout video based on detected music tempo and user preferences. By adjusting this key parameter, the system enables users to workout at comfortable speeds while ensuring the video content remains synchronized with the music through coordinated speed adjustment of both video and audio tracks.
2Speed
If the playback speed of workout video is increased to match faster music tempo, then the workout intensity increases, but the video content and audio become desynchronized
Solution Approach 1:
The patent merges the speed control of video and audio together, adjusting both at the same rate. When the playback speed is changed to match music tempo or user ability, both the video content and the accompanying audio are synchronized by applying the same speed adjustment factor to both streams, preventing desynchronization.
3Object-affected harmful factors
If the workout video speed is adjusted to match user ability, then user safety and engagement improve, but the system complexity increases due to speed detection and adjustment mechanisms
Solution Approach 1:
The system uses the music that is already part of the workout video to determine the playback speed. By analyzing the tempo of the existing music track, the system automatically determines the appropriate video speed without requiring external sensors or complex user input, making the safety feature relatively simple to implement.

AI summary
An electronic device, according to one embodiment, comprises a display and at least one processor operatively connected to the display, wherein the at least one processor may play a workout video through the display, identify the speed of a workout move included in the workout video, identify an audio signal that is distinct from the workout video, identify a play speed of the workout video at which the speed of the workout move corresponds to the tempo of the audio signal, and control the play speed of the workout video so that same corresponds to the identified play speed of the workout video.
