Augmented Reality Sonar Overlays for Moving Fish Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Anglers and watercraft operators face challenges in accurately determining the location of moving targets, such as fish, and navigating complex environments due to the need to frequently look at displays and process complex charts, leading to potential user errors and difficulty in making quick decisions.
Innovation Solution
Augmented reality devices are used to present live sonar images superimposed on the surrounding environment, allowing users to maintain visibility of their surroundings while providing transparent sonar information, with features like target highlighting, speed and direction vectors, and hazard representations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the angler looks at the display on the watercraft to determine fish location, then the sonar information is obtained, but the fish have likely moved away by the time the angler reaches the fishing location
Solution Approach 1:
The patent introduces an augmented reality device as an intermediary between the sonar system and the angler. The device overlays sonar images directly onto the angler's field of view, allowing real-time fish location tracking without requiring the angler to look away at a separate display. This eliminates the time delay while maintaining accurate fish location information.
2Loss of information
If the angler frequently looks at the display to track moving fish, then the latest sonar information is obtained, but the surrounding environment becomes less visible
Solution Approach 1:
The patent merges the sonar display with the view of the surrounding environment by overlaying sonar images directly onto the augmented reality device's display. This allows the angler to see both the sonar information and the environment simultaneously in a single field of view, eliminating the need to switch between separate displays and maintaining awareness of both fish location and environmental context.
3Loss of information
If complex charts and maps are reviewed for navigation, then navigation information is obtained, but the process is tedious and prone to user error
Solution Approach 1:
The augmented reality device serves as an intermediary that processes complex navigation charts and maps into simplified visual overlays. The device presents navigation information directly in the context of the surrounding environment, showing recommended travel paths and target locations overlaid on the actual view, which eliminates the need to interpret complex standalone charts and reduces user error.

AI summary
An augmented reality system is provided including an augmented reality device comprising a display configured to allow a user to view a portion of a surrounding environment through the display. The portion of the surrounding environment corresponds to a current viewpoint of the user such that the user would otherwise see the portion if the device was not present. The system includes processor(s) and memory device(s) comprising computer program code configured, when executed by the processor(s), to cause the processor(s) to determine a position and line of sight of the device, receive a live sonar image, correlate the position and line of sight to a corresponding portion of the image, and cause presentation of the image on portion(s) of the display so that the portion of the surrounding environment and the corresponding portion of the image are both visible in the display from a user's perspective.
