Dynamic Playback Speed Control for Multi-User Exercise Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems that synchronize the playback speed of moving images for multiple users exercising together often fail to accommodate varying athletic performances, leading to mismatched exercise experiences and difficulty in simultaneous participation.
Innovation Solution
A system that includes a sensor to measure exercise quantity and an information processing apparatus that adjusts the playback speed of moving images based on individual exercise quantities and attributable ratios, allowing each user to experience a playback speed suitable to their athletic performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a uniform playback speed is used for all users exercising together, then the system is simple to operate, but users with different athletic performances experience mismatched exercise loads
Solution Approach 1:
The playback speed is dynamically adjusted for each user based on their exercise quantity and attributable ratio. The system continuously monitors exercise data and modifies playback speed in real-time, transforming the static uniform speed into a dynamic personalized speed that adapts to each user's athletic performance and exercise intensity.
Solution Approach 2:
Each user is assigned a specific attributable ratio that reflects their individual exercise capacity and role in the group exercise. This creates local quality differences where each user experiences a playback speed tailored to their specific needs, while the overall system maintains synchronization through the weighted aggregation of individual contributions.
2Adaptability or versatility
If the playback speed is adjusted according to each user's exercise quantity, then individual exercise experience is improved, but the system complexity increases
Solution Approach 1:
The information processing apparatus performs multiple functions: it monitors exercise quantity, calculates attributable ratios, determines personalized playback speeds, and aggregates individual contributions. By consolidating these diverse functions into a single multi-functional system, the patent reduces overall complexity compared to having separate systems for each function.
Solution Approach 2:
The system manages complexity by focusing on changing key parameters (exercise quantity, attributable ratio, playback speed) rather than restructuring the entire system. The attributable ratio serves as a configurable parameter that simplifies the relationship between individual exercise performance and group synchronization, making the system more manageable despite its adaptive capabilities.
3Adaptability or versatility
If multiple users exercise simultaneously with different athletic levels, then user participation is enhanced, but synchronizing playback speed becomes difficult
Solution Approach 1:
The system continuously monitors exercise quantity from sensors and uses this feedback to adjust playback speed in real-time. This closed-loop control ensures that users with different athletic levels can exercise simultaneously while maintaining appropriate synchronization, as the system constantly adapts to actual exercise performance rather than relying on pre-set speeds.
Solution Approach 2:
The attributable ratio acts as an intermediary parameter that mediates between individual exercise quantity and group playback speed synchronization. It provides a weighted relationship that allows users with different athletic performances to contribute differently to the overall playback speed, enabling simultaneous participation while maintaining precise synchronization through mathematical weighting.

AI summary
A system includes a sensor configured to output information relating to an exercise quantity of a user who performs exercise while viewing a moving image; and an information processing apparatus including a processor; and a memory that includes instructions, which when executed, cause the processor to execute controlling displaying of the moving image, and playing back the moving image at a playback speed determined based on the information relating to the exercise quantity of each of a plurality of the users output from the sensor, and a attributable ratio of the exercise quantity with respect to the playback speed of the moving image set for each of the plurality of the users.
