Touch Screen Icon Management via Dynamic Drag
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile terminals display numerous menu icons, which hinder user convenience and cause confusion, as existing solutions fail to effectively facilitate the identification and selection of specific icons.
Innovation Solution
A terminal equipped with a touch screen and a control unit that allows touch-available icons to move between outer and inner areas of the screen via a touch-drag operation, enabling users to easily display and select menu icons by sliding them across the screen.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If numerous menu icons are displayed on the screen to provide various functions, then the functionality and versatility of the terminal is improved, but the user convenience and ease of operation deteriorates due to clutter and confusion
Solution Approach 1:
The menu icons are made dynamically movable between inner and outer areas of the screen through touch-drag operations. This dynamic repositioning allows the interface to adapt to user needs while maintaining clarity, resolving the contradiction between providing numerous functions and ensuring ease of operation.
Solution Approach 2:
The patent introduces a spatial dimension by dividing the screen into inner and outer areas. Icons can be moved between these areas, effectively utilizing screen space more efficiently and reducing clutter in the main viewing area while maintaining access to all functions.
2Ease of operation
If all menu icons are displayed simultaneously on the screen, then user access to various functions is improved, but power consumption increases and screen clutter worsens
Solution Approach 1:
Menu icons are extracted from the main inner area and placed in the outer area when not currently needed. This extraction reduces screen clutter and power consumption while maintaining the ability to access all functions through the touch-drag mechanism.
Solution Approach 2:
The display state of menu icons is made dynamic, allowing them to be moved between inner and outer areas based on usage needs. This dynamic behavior enables the system to consume less power by not continuously rendering all icons in the main display area.
3Ease of operation
If menu icons are made movable between inner and outer areas via touch-drag, then ease of operation and user convenience are improved, but device complexity increases
Solution Approach 1:
The user directly manipulates the menu icons through touch-drag operations to move them between inner and outer areas. This self-service approach eliminates the need for complex automated control systems, as the user's direct interaction simplifies the control mechanism while improving ease of operation.

AI summary
A terminal can include a touch screen, and a control unit to control at least one touch-available icon to appear on the touch screen in a first direction of a first touch-drag on the touch screen, in response to a touch input to one of the at least one touch-available icon, execute a specific function such that an execution image related to the executed specific function is displayed on the touch screen. Further, the control unit of the terminal can receive a message while the specific function is being executed, receive a second touch-drag in a second direction on the touch screen, and control a message window for the received message to appear on the touch screen.
