Display Device Pointer Control for Local Text Search
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of digital TV services face inconvenience when searching for specific text on the screen, requiring manual input and selection of search criteria, leading to inefficiencies and imprecise results.
Innovation Solution
A display device equipped with a user input interface and controller that allows direct text recognition and search functionality by positioning a pointer on the desired text, extracting and analyzing the text for search operations, and providing search results without manual input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual text input and search function execution are required, then search functionality is provided, but user convenience and search efficiency deteriorate
Solution Approach 1:
The system automatically extracts text from the area where the pointer is positioned without requiring manual input from the user. The controller detects the pointer position, extracts the corresponding text, and executes the search function automatically, allowing the system to serve itself rather than requiring user intervention for text input
Solution Approach 2:
The text extraction is performed in advance as part of the search initiation process. When the user positions the pointer and triggers the search, the system has already prepared the search text by extracting it from the pointer position, eliminating the need for subsequent manual text entry
2Measurement precision
If search is performed on the entire screen, then comprehensive search coverage is achieved, but search precision and relevance deteriorate
Solution Approach 1:
The search function focuses on a specific local area rather than the entire screen. By extracting text only from the area where the pointer is positioned, the system applies different search scopes to different regions of the display, making the search both precise and contextually relevant to the user's intent

AI summary
The present invention relates to a display device which directly executes searching related to text displayed on a screen, the display device comprising: a display unit for displaying content; a user input interface unit for receiving a control signal of a pointer being displayed on the content; and a control unit for, when a search command is received, controlling the display unit to display a search result of the text displayed on an area where the pointer is located.
