AR VR Golf Training System with Real-Time Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing golf training and simulation systems lack immersive augmented reality (AR) feedback during the swing, providing marginal accuracy and lacking fine swing analytics, while also being non-portable and requiring significant space.
Innovation Solution
The system employs stereoscopic video passthrough AR/VR goggles with 6DoF tracking, allowing users to interact with real world sports equipment and providing real-time AR feedback that seamlessly transitions to immersive VR, enabling synchronized simulation and training in mixed reality environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional golf simulation systems use separate monitors for display, then users can focus on the golf tee area, but the system lacks immersive AR feedback during the swing
Solution Approach 1:
The patent uses AR markers placed on the golf ball as an intermediary element. These markers enable the system to track ball motion and provide immersive AR feedback during the swing without requiring the user to shift focus to a separate monitor. The markers serve as a bridge between the physical golf ball and the digital tracking system, allowing precise measurement and real-time visual feedback to be overlaid on the user's field of view.
Solution Approach 2:
The patent replaces the traditional mechanical display system (separate monitors) with an optical-based AR feedback system. Instead of using external displays that require the user to shift attention, the system uses AR technology to project feedback directly into the user's visual field, substituting mechanical display mechanisms with optical overlay technology that maintains immersion.
2Loss of information
If AR feedback is provided during the swing using separate screens, then real-time metrics are available, but the user's eyes must sequence between the ball and display screen
Solution Approach 1:
The patent merges the AR feedback display with the user's natural field of view by overlaying metrics directly on the visual scene containing the golf ball. Instead of separating the feedback display from the target object, the system combines them into a single integrated visual experience, eliminating the need for eye sequencing between separate screens and reducing time loss.
3Adaptability or versatility
If golf simulators use infrared sensors in floor pads to track club motion, then standard golf club motion can be tracked, but the system lacks fine swing analytics and portability
Solution Approach 1:
The patent segments the tracking system into multiple independent components: AR markers on the golf ball for ball motion tracking, cameras for visual capture, and computational algorithms for analytics. This segmentation allows the system to achieve fine swing analytics precision through coordinated data from multiple sources while maintaining compatibility with standard golf equipment, as each component can be optimized independently.
4Ease of operation
If immersive VR environment is used for simulation, then user immersion is enhanced, but user safety may be compromised without real world awareness
Solution Approach 1:
The patent implements periodic transitions between AR and VR modes during the golf swing sequence. The system uses AR during the address and swing preparation phases to maintain real-world awareness and safety, then transitions to immersive VR during the follow-through and ball flight observation phases when safety is less critical. This periodic switching optimizes both immersion and safety at different stages of the activity.

AI summary
A system and method are disclosed for creating a simulation that utilizes Augmented Reality (AR) and Virtual Reality (VR) to enable at least two persons to occupy the same space in a virtual environment. The system and method allow for the use of existing real world devices (e.g., sports equipment), also displaying the real world devices in both AR and VR modes in the same space in a virtual environment. By coexisting in the same virtual space in the simulated environment, a student can literally see the exact stance and movement (e.g., golf swing) of a collocated instructor or coach from his or her own perspective.
