Depth-Based GUI Navigation for Mobile Search Interfaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The usability of search functions in mobile environments is not adequately considered, leading to suboptimal user experiences when applying PC search functionalities to mobile devices.
Innovation Solution
A display apparatus and controlling method that utilize a tree structure to organize domains, allowing for a depth-based GUI representation, user interface for command reception, and controller-driven navigation between domains, including search, application, and user history domains, enhancing user interaction by providing a structured and intuitive search interface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If PC search function is applied to mobile environment, then search capability is provided, but usability is not considered
Solution Approach 1:
The search interface is segmented into multiple depth levels (first GUI for top-level domains, second GUI for sub-domains) allowing users to navigate systematically through organized categories rather than facing a single overwhelming search field, thus improving mobile usability while maintaining search capability
Solution Approach 2:
The patent introduces a depth dimension to the search interface by organizing domains hierarchically across multiple GUI levels. This dimensional organization transforms the flat PC search model into a structured mobile-friendly interface where users can explore sub-domains systematically
2Adaptability or versatility
If multiple domains and sub-domains are displayed, then comprehensive search coverage is provided, but screen loading complexity increases
Solution Approach 1:
The comprehensive domain structure is segmented across multiple depth levels and GUI screens. Instead of loading all domains simultaneously, the system divides them into manageable groups (first GUI for top domains, second GUI for sub-domains) that are loaded and displayed progressively based on user navigation, reducing initial screen complexity while maintaining comprehensive coverage
Solution Approach 2:
The domain hierarchy is pre-organized into a structured tree format with defined depth levels and relationships. This preliminary structuring allows the system to efficiently manage and load only the relevant portion of domains at each GUI level, avoiding the need to load the entire domain structure at once

AI summary
A display apparatus is provided. The display apparatus includes a display configured to display at least one of a first Graphic User Interface (GUI) representing a domain which provides an execution screen according to a depth, a user interface configured to receive a user command, and a controller configured to, when one of the at least one of the first GUI is selected according to the user command, display at least one of a second GUI representing a sub domain which is available in a domain represented by the selected first GUI, and when one of the at least one of the second GUI is selected, provide an execution screen corresponding to the sub domain based on sub domain information which is mapped with the selected second GUI.
