Solution Overview
Problem
Existing online training systems for racquet sports fail to provide an immersive and effective experience for remote participants, lacking synchronization and performance monitoring, and do not allow access to world-class trainers from the comfort of home.
Innovation Solution
A system and method for real-time interactive training that includes an in-studio component and user devices connected over a network, enabling demonstration, training, and performance, and results modes, with synchronized video feeds, motion tracking, and feedback mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If online training systems are used for remote participants, then accessibility to world-class trainers is improved, but training effectiveness and immersion are degraded
Solution Approach 1:
The system creates a virtual copy of the in-facility training experience by streaming video feeds from the trainer's location to remote user devices. This allows participants to access world-class trainers remotely while maintaining visual and instructional fidelity through synchronized video transmission and overlay graphics that replicate the on-court experience.
Solution Approach 2:
The system introduces synchronization technology and performance monitoring tools as intermediaries between the trainer and remote participants. These tools include motion tracking cameras, performance metrics display, and synchronized video feeds that mediate the interaction to maintain training effectiveness despite physical separation.
2Measurement precision
If synchronized video feeds and motion tracking are implemented, then performance monitoring capability is improved, but system complexity increases
Solution Approach 1:
The system employs multi-functional devices that serve multiple purposes: user devices function as both video displays and motion tracking cameras, while the synchronization server handles both video streaming and performance data processing. This reduces overall system complexity by eliminating dedicated single-function components.
Solution Approach 2:
The system merges video feed transmission and performance data synchronization into a unified communication protocol. The synchronization server combines multiple data streams (video, motion tracking, performance metrics) into coordinated outputs that are delivered to user devices, reducing the number of separate systems needed.
3Reliability
If real-time feedback mechanisms are added, then training quality is improved, but computational requirements increase
Solution Approach 1:
The system performs preliminary processing of performance data on the user device itself rather than requiring all computations to be performed by the remote server. Motion tracking and performance metric calculations are executed locally, reducing the computational burden on centralized systems and enabling faster real-time feedback.
Solution Approach 2:
The system enables user devices to autonomously process and analyze their own performance data without requiring constant communication with the remote training system. This self-service capability reduces computational requirements for real-time feedback by distributing processing tasks to the edge devices.
Data Source
AI summary
A training system operates to provide an online training system for a racquet sport that includes an instructional portion, a performance portion and a results report. A trainer can create training modules and/or training programs and then launch a training program in which one or more users, utilizing a user system, can participate. A training program consists of one or more training modules. The training modules include targets to indicate the type of swing or shot that the participant is being instructed to make. The system can monitor and track the participant's performance and provide feedback for improvements.
