Basketball Skill Simulation With Anatomical Parameter Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The anatomical differences between amateur and professional athletes make it difficult to accurately compare their performance, as existing methods do not account for variations in hand size, reach, and height, leading to inaccurate assessments of an amateur's skills.
Innovation Solution
A simulation system that adjusts basketball equipment and court dimensions based on the amateur's physical characteristics to simulate performance against a professional athlete, using a head-mounted display, position sensing devices, and a controller to generate a virtual environment for skill assessment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If direct performance comparison is made between amateur and professional athletes, then simplicity of assessment is improved, but measurement precision deteriorates due to anatomical differences
Solution Approach 1:
The patent introduces a simulation system as an intermediary between amateur and professional athlete performance assessments. The system creates a virtual professional athlete with identical anatomical characteristics (height, wingspan, hand size) to the amateur player, allowing skill comparison without direct physical comparison. This mediator eliminates the measurement error caused by anatomical differences while maintaining assessment simplicity.
Solution Approach 2:
The system changes the parameters of the comparison by creating a virtual professional athlete whose anatomical parameters (height, wingspan, hand size) are set to match the amateur player's actual measurements. This parameter adjustment allows for fair skill comparison by removing the confounding variable of anatomical differences, thereby improving measurement precision without complicating the assessment process.
2Measurement precision
If virtual environment simulation is implemented, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent creates a virtual copy of the professional athlete with anatomical parameters copied from the amateur player's measurements. This digital copy allows precise skill comparison in a controlled virtual environment. The copying approach achieves high measurement precision while keeping the system relatively simple, as it only requires capturing basic anatomical measurements and rendering a corresponding virtual model.
Solution Approach 2:
The system replaces physical mechanical comparison (direct competition or side-by-side measurement) with a computational virtual environment. By substituting the mechanical assessment system with software-based simulation, the patent achieves precise measurement control while managing device complexity through digital rather than physical means.
3Measurement precision
If anatomical measurements are collected and processed, then measurement precision is improved, but loss of time increases
Solution Approach 1:
The patent performs preliminary action by collecting and storing anatomical measurements (height, wingspan, hand size) of the amateur player before the actual skill assessment. These measurements are processed in advance to create the virtual professional athlete's anatomical parameters. This preliminary data collection and processing eliminates the need for repeated measurements during assessment, thereby improving measurement precision while minimizing time loss through one-time upfront data gathering.

AI summary
A simulation system in which an amateur player may obtain an assessment of how the amateur players skills compare to those of an average professional athlete or a selected professional athlete that takes into consideration the physical differences between the amateur player and the professional athlete. Measurements of an amateur player are obtained and compared to those of a professional athlete. Such comparisons are used to adjust parameters for a physical or virtual simulation that may be used to assess the abilities of amateur player relative to that of the professional athlete.
