Head-Mounted Display for Golf Ball Trajectory Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Golfers face difficulties in tracking the trajectory and locating golf balls in flight and after landing due to their visibility challenges on a golf course.
Innovation Solution
A system comprising a display device worn on the user's head, equipped with a camera, golf ball tracking system, and processor, which captures and records images to display an enhanced image of the golf ball's trajectory and location, including a comet tail, on a heads-up display, allowing users to view the ball's path and find it easily.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If golfers rely on natural vision to track golf balls, then the system remains simple, but the golf ball is difficult to see and track when flying through the air
Solution Approach 1:
The patent introduces an intermediary system consisting of a camera, processor, and display device that mediates between the golf ball and the golfer's vision. The camera captures the golf ball's position, the processor enhances and processes this information, and the display device presents it to the golfer, thereby solving the visibility problem without requiring direct visual detection by the human eye.
Solution Approach 2:
The system creates a visual copy or representation of the golf ball through the display device. Instead of relying on direct visual detection of the actual golf ball, the system captures images of the golf ball and displays enhanced versions of these images, allowing the golfer to track the ball's trajectory through this intermediary visual copy.
2Ease of operation
If golfers use a display device to track the golf ball, then visibility and tracking improve, but hands-free operation becomes challenging
Solution Approach 1:
The display device is designed to be worn on the head, making it universally applicable and hands-free. This multi-functional device serves as both a camera platform and a display system, eliminating the need for separate handheld devices and enabling golfers to track the ball without using their hands.
Solution Approach 2:
The system transitions from two-dimensional screen viewing to three-dimensional spatial display by projecting the enhanced golf ball image into the golfer's field of view. This dimensional change allows natural head and eye movements to be used for tracking, eliminating the need for hand operations to adjust or point at a screen.
3Loss of information
If enhanced images are displayed to improve golf ball visibility, then tracking accuracy improves, but information overload may occur
Solution Approach 1:
The system extracts only the essential trajectory information from the complex visual scene and displays it as an enhanced image of the golf ball. By isolating and highlighting the relevant information (the ball's position and path) while filtering out extraneous details, the system prevents information overload while maintaining complete trajectory data.
Solution Approach 2:
The enhancement is applied locally to the golf ball region rather than to the entire visual field. The processor identifies the golf ball's position and applies enhancement algorithms specifically to that local area, preserving trajectory information while avoiding the complexity of processing and displaying enhanced information across the entire scene.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables golfers to track the golf ball's trajectory and locate it efficiently by overlaying enhanced images onto their real-world view, providing hands-free comparison with ideal trajectories and displaying launch and flight information.
Implementation Method 1
The golf ball tracking system may include a golf ball having a signal emitter. A signal receiver may be disposed on the display device and configured to receive a signal emitted by the signal emitter.

AI summary
The application relates to a system for helping a user navigate and/or determine distances between the user and landmarks. The system comprises a user tracking system (206) to track the location of the user; and a display device configured to be worn on a user's head and including a display system (208) configured to display images to the user. The system further comprises a processor configured to control the user tracking system (206) and the display system (208). The processor is configured to determine a distance between the location of the user and a landmark; and display the distance between the location of the user and the landmark on the display device.
