Virtual Reality Sports Tracking System Using 3D Flight Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing virtual reality systems fail to allow users to experience the performance of athletes in live sports videos, limiting the engagement and immersion for viewers.
Innovation Solution
A virtual-reality provision system that acquires tracking data of flying objects from sensors, generates three-dimensional display data to show a virtual flying object, and transmits this data to a virtual-space provision system for display, allowing users to experience the performance from a first-person perspective.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If traditional video broadcasting is used to show sports events, then viewers can watch the performance of athletes, but they cannot experience the performance of the athlete
Solution Approach 1:
The patent creates a virtual copy of the flying object (ball, etc.) in three-dimensional space that replicates the real object's motion trajectory. By generating virtual reality data that copies the physical object's movement, the system enables users to experience the athlete's performance from multiple perspectives without requiring complex multi-camera setups or direct athlete interaction.
Solution Approach 2:
The patent transitions from two-dimensional video broadcasting to three-dimensional virtual reality representation. By adding the depth dimension and enabling spatial navigation, users can view the flying object's trajectory from any angle, gaining experiential insight into the athlete's performance that flat video cannot provide.
2Measurement precision
If sensors and tracking systems are used to capture flying object data, then tracking precision is improved, but device complexity increases
Solution Approach 1:
The patent employs sensors with broad detection capabilities that can track multiple parameters (position, velocity, acceleration) of the flying object simultaneously. This multi-functional approach achieves high measurement precision without requiring separate specialized sensors for each parameter, thereby limiting the increase in device complexity.
3Adaptability or versatility
If three-dimensional display data is generated and transmitted in real-time, then user immersion is improved, but data transmission requirements increase
Solution Approach 1:
The patent divides the three-dimensional display data into essential components (trajectory coordinates, temporal information, spatial relationships) and transmits only these critical elements. By segmenting the data transmission, the system maintains high user immersion through accurate virtual object representation while reducing the overall data volume compared to transmitting complete graphical models or uncompressed video feeds.
Data Source
AI summary
Provided is a virtual-reality provision system having: a tracking data acquisition unit that acquires tracking data on a flying object thrown by an athlete, the data being obtained from sensor information from a sensor that tracks the flying object; a three-dimensional-display-data generation unit that uses the acquired tracking data to generate three-dimensional display data used to display, in a virtual space, a flight video of a virtual flying object corresponding to said flying object; at least one virtual-space provision system that displays the flight video of the virtual flying object in the virtual space by using the three-dimensional display data; and a transmission unit that transmits the three-dimensional display data to the at least one virtual-space provision system.
