Drag-and-Drop Screen Object Management for Digital TV
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current image display devices lack an intuitive and user-friendly method for controlling and organizing multiple applications and services, particularly in digital TV systems, which hinders ease of use and interactivity.
Innovation Solution
A method and device for controlling a screen display that allows objects to be dragged and dropped between areas, enabling intuitive reorganization and management of applications, enhancing user interaction and service access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional menu navigation methods are used in digital TV systems, then system stability is maintained, but ease of operation deteriorates due to lack of intuitive control
Solution Approach 1:
The patent replaces traditional mechanical menu navigation (using remote control buttons and hierarchical menus) with a drag-and-drop graphical interface. Users can directly manipulate application icons and objects on the screen by dragging them to desired positions, eliminating the need for complex menu traversal and button sequences. This substitution of mechanical navigation with intuitive graphical manipulation directly improves ease of operation.
Solution Approach 2:
The drag-and-drop interface enables users to directly reorganize and manage applications without requiring system-mediated menu selections or complex command sequences. Users take direct control of interface elements, dragging them to desired locations and dropping them into target areas, allowing self-service reorganization of the user interface without system intervention or complex navigation protocols.
2Adaptability or versatility
If multiple applications are displayed simultaneously, then adaptability improves, but screen space management becomes complex
Solution Approach 1:
The patent implements a dynamic screen layout where application icons and objects can be freely moved and repositioned by users. The interface adapts to user preferences through drag-and-drop operations, allowing applications to be arranged in different configurations based on usage frequency and user preference. This dynamic reorganization capability enables multiple applications to coexist on screen without fixed positional constraints, improving adaptability while simplifying screen space management.
Solution Approach 2:
The screen is divided into independent draggable objects and drop target areas, allowing users to manage multiple applications as separate, movable units. Each application icon can be independently positioned and organized into different functional groups or areas, enabling flexible screen space management that adapts to the number and type of applications being used simultaneously.
3Ease of operation
If drag and drop operation is implemented, then ease of operation improves, but device complexity increases due to additional control mechanisms
Solution Approach 1:
The patent replaces complex mechanical control sequences (multiple button presses, menu navigations) with a simple drag-and-drop graphical operation. The control mechanism leverages the display device's native graphical interface capabilities rather than requiring additional hardware controls or complex software protocols, implementing intuitive manipulation directly through the existing display and touch/cursor interface.

AI summary
Provided are a method of controlling a screen display and an image display device using the same. The method includes: displaying a first object and a second object on a screen; as the first object displayed in a first area is dragged toward the second object, displaying a second area including the second object as a drop position of the first object; and as the first object is dropped in the second area, moving the first object to the second area and displaying the moved first object.
