Display Device Object Tracking for Automatic Zoom Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices, such as smart TVs, lack the ability to automatically track and enlarge specific objects, like a soccer ball, during fast movements, leading to user inconvenience.
Innovation Solution
A display device and control method that allows users to specify an object, automatically track its movement, and adjust the screen enlargement accordingly, with features like guide lines and automatic zoom-out/zoom-in based on object position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the screen enlargement function is performed on videos with frequent object movement, then the user can enlarge the screen to watch objects closer, but the zoom screen must be moved continuously to track object position changes, causing user inconvenience
Solution Approach 1:
The system automatically tracks the selected object and adjusts the zoom screen position without requiring manual user intervention. The object detection module continuously monitors object positions and the zoom control module automatically repositions the enlarged view to follow the object's movement, making the system self-adjusting and eliminating the need for users to manually track moving objects.
Solution Approach 2:
The system implements a feedback loop where the object detection module detects object positions in real-time, feeds this information back to the zoom control module, which then adjusts the zoom screen position accordingly. This closed-loop feedback mechanism ensures continuous accurate tracking of moving objects while maintaining the enlarged view on the display.
2Adaptability or versatility
If the zoom screen is moved continuously to track object position changes, then the user can follow the object movement, but the operation becomes complex and time-consuming
Solution Approach 1:
The system performs self-adjustment by automatically detecting object positions and repositioning the zoom screen without user intervention. The object detection module continuously monitors the display for object position changes and the zoom control module autonomously adjusts the enlarged view to follow the object, eliminating the need for complex manual control operations.
Solution Approach 2:
The system performs preliminary actions by pre-configuring the zoom function and object detection capabilities before actual use. When an object is selected, the system is already prepared to automatically track and adjust the zoom screen position in real-time, eliminating the need for users to perform complex control sequences during object tracking.
3Ease of operation
If manual tracking of moving objects is required, then the user can control the zoom position, but the user experience deteriorates due to continuous adjustment requirements
Solution Approach 1:
The system automatically performs the time-consuming task of continuous zoom position adjustment by detecting object movement and autonomously repositioning the enlarged view. This self-service mechanism eliminates the need for users to continuously manually adjust the zoom screen, significantly reducing the time and effort required to track moving objects.
