Workout Video Speed Control for Tempo-Matched Exercise Pacing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Workout videos have fixed speeds that may not align with individual user preferences, leading to user dropout or injury due to mismatched workout speed and music tempo, and difficulty in finding suitable difficulty levels.
Innovation Solution
An electronic device that adjusts workout video playback speed to match the tempo of separate audio signals, ensuring synchronized motion and audio pacing, and adjusts based on user workout speed to prevent injury.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the workout video speed is fixed, then the video content remains consistent, but the user cannot adjust to their individual workout ability leading to dropout or injury
Solution Approach 1:
The patent implements dynamic speed adjustment by automatically changing the workout video playback speed based on real-time analysis of user motion speed. The system transitions from a fixed-speed video to a dynamically adaptive video that adjusts its tempo to match the user's actual workout pace, thereby improving adaptability while maintaining safety through continuous monitoring and adjustment.
Solution Approach 2:
The system employs feedback mechanisms by capturing the user's workout video, analyzing their motion speed, and using this information to adjust the workout video speed. This closed-loop feedback ensures the video speed continuously adapts to the user's ability, preventing both dropout (by making it fast enough) and injury (by not exceeding safe limits).
2Productivity
If the workout video speed is increased to match faster tempo, then workout efficiency improves, but the user may overexert and get injured
Solution Approach 1:
The system continuously monitors the user's actual workout speed through video analysis and provides feedback to adjust the workout video speed. This ensures the video tempo matches the user's capability, maximizing workout efficiency without exceeding safe limits that could cause injury.
Solution Approach 2:
The patent dynamically changes the playback speed parameter of the workout video based on analyzed user performance. By adjusting this critical parameter in real-time, the system optimizes workout efficiency while preventing overexertion, as the speed increases only to the extent the user can safely handle.

AI summary
An electronic device includes a display and at least one processor operatively connected to the display. 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 target play speed of the workout video at which the speed of the workout move corresponds to the tempo of the audio signal, and control a play speed of the workout video such that the play speed corresponds to the identified target play speed of the workout video.
