Exercise Machine Control via Video Subtitle Encoding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mental health treatments often lack the effectiveness and side-effect-free benefits of combining exercise with therapy or medication, particularly in enhancing mental well-being and reducing symptoms like anxiety and depression.
Innovation Solution
A method to create a video workout program by combining a trainer's workout video with an environmental video, encoding exercise machine control commands into the subtitle stream, allowing the exercise machine to control its movements synchronously with the video, and enabling interactive features like virtual environments and real-time feedback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a trainer performs a workout on a stationary exercise machine in front of a chroma key screen, then the virtual environment can be synchronized with the exercise machine's movements, but the complexity of video production and processing increases
Solution Approach 1:
The chroma key screen is set up in advance during video production, allowing the virtual environment to be pre-synchronized with the exercise machine's movement patterns. This preliminary setup enables automatic synchronization during playback without requiring complex real-time processing, thus maintaining reliability while reducing operational complexity.
Solution Approach 2:
The chroma key screen acts as an intermediary between the physical exercise machine and the virtual environment. By capturing the trainer's movements against the chroma key background, the system creates a bridge that automatically maps physical movements to virtual environment changes, simplifying the synchronization process while maintaining reliability.
2Extent of automation
If exercise machine control commands are encoded into the subtitle stream of the combined video, then the exercise machine can be controlled automatically during workout execution, but the manufacturing precision of the video workout program increases
Solution Approach 1:
The exercise machine control commands are merged into the subtitle stream of the combined video. This integration allows the video to simultaneously serve as both the workout instruction and the control signal source, enabling automatic machine control while maintaining precise synchronization between video playback and machine movements through a single unified format.
3Adaptability or versatility
If the second video moves through a virtual environment synchronized with the trainer's workout speed, then the immersive experience is enhanced, but the device complexity increases
Solution Approach 1:
The virtual environment video is pre-synchronized with the trainer's workout speed during production. By establishing the speed relationship in advance, the system eliminates the need for complex real-time speed analysis and adjustment mechanisms, achieving virtual environment adaptability while keeping the processing system relatively simple.
Solution Approach 2:
The virtual environment video copies the movement patterns and speed of the trainer's workout. This copying approach allows the virtual environment to adapt to different workout speeds without requiring complex analytical systems, as the virtual video simply mirrors the physical workout's temporal characteristics.
Data Source
AI summary
In one aspect of the disclosure, a method includes rendering, by a processor, a virtual environment associating, by the processor, exercise machine control signals with the virtual environment, and displaying, by the processor, the virtual environment on a video wall. The method may include receiving, by the processor, a video of a trainer on an exercise machine in front of the video wall displaying the virtual environment, wherein the exercise machine has one or more parameters which are controlled according to the exercise machine control signals associated with the virtual environment, associating, by the processor, the control signals with the video of the trainer in the virtual environment, and publishing the video with the associated control signals for use on a remote exercise machine.
