Display Interface for Fish Counting, Recording, and Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fish counting systems lack intuitive user interfaces for instructing video recording and fish counting operations, making it difficult for users to effectively manage and analyze fish data.
Innovation Solution
A display device with a main screen featuring selectable instruction items for recording and analysis, allowing users to intuitively control video recording and fish counting through a display control program.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional fish counting system is used, then fish counting functionality is provided, but the user interface is not intuitive and users cannot easily recognize or control video recording and fish counting operations
Solution Approach 1:
The display screen is segmented into multiple functional regions: a video display region showing real-time fish footage, and a separate display region showing counted fish numbers. This spatial segmentation allows users to simultaneously view both the video feed and counting results without confusion, making the system's capabilities immediately recognizable and easier to operate.
Solution Approach 2:
A display control unit is introduced as an intermediary between the processing unit and the display unit. This mediator selectively outputs and displays different information (video frames, counted fish numbers, or both simultaneously) based on control signals, enabling intuitive user interaction by presenting information in a comprehensible format rather than raw data streams.
2Adaptability or versatility
If video recording and fish counting are integrated, then comprehensive fish management is achieved, but the system complexity increases
Solution Approach 1:
The display unit is designed with multi-functionality to display different types of information (video frames, counted fish numbers, or both) based on the same hardware resources. The display control unit manages these different display modes, allowing the system to perform both video recording and fish counting functions through a unified interface, thereby increasing versatility without proportionally increasing device complexity.
3Measurement precision
If fish counting analysis is performed on recorded video, then accurate fish population data is obtained, but processing time increases
Solution Approach 1:
The system performs preliminary actions by continuously capturing and storing video footage of fish during the observation period. This recorded video serves as pre-processed data that can be analyzed later for fish counting, eliminating the need for real-time processing and allowing accurate counting to be performed on already-captured footage, thus reducing processing time while maintaining accuracy.

AI summary
A display device is used for a number-of-fish counting system for counting the number of fish. The display device is provided with a display unit that displays a plurality of selectable instruction items on a main screen. The plurality of instruction items include a recording instruction item that instructs a processing device of the number-of-fish counting system to execute or stop recording of video of fish, and an analysis instruction item that instructs the processing device to count the number of the fish by analyzing the fish on the basis of the recorded video.
