Focus GUI Movement Direction Determination in Electronic Apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulty in predicting the movement direction of a focus GUI on a UI screen with multiple GUI items, especially when wheel inputs are received in a vertical direction, leading to confusion about whether the focus GUI moves horizontally or vertically.
Innovation Solution
An electronic apparatus and method that determine the movement direction of a focus GUI based on the direction in which a GUI item is movable, identifying possible movement directions from arrangement information, and prioritizing horizontal movement when both horizontal and vertical directions are possible.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the focus GUI is allowed to move in both horizontal and vertical directions based on wheel input, then the navigation flexibility is improved, but the user predictability and ease of operation deteriorates due to confusion about movement direction
Solution Approach 1:
The system dynamically determines the movement direction of the focus GUI based on the arrangement information of GUI items. When GUI items can be moved in multiple directions, the system adapts the focus GUI movement to match the permissible direction, making the behavior predictable while maintaining navigation flexibility.
Solution Approach 2:
The system changes the movement parameter (direction) of the focus GUI based on the arrangement information of GUI items. By identifying whether GUI items can be moved horizontally, vertically, or in both directions, the system adjusts the focus GUI movement accordingly, resolving the contradiction between flexibility and predictability.
2Ease of operation
If the focus GUI movement direction is determined by wheel input direction alone, then the operation simplicity is improved, but the user confusion increases when GUI items can move in multiple directions
Solution Approach 1:
The system introduces arrangement information as an intermediary factor that mediates between the wheel input direction and the focus GUI movement direction. This intermediary clarifies the relationship by identifying the permissible movement directions of GUI items, eliminating confusion while maintaining operational simplicity.
Solution Approach 2:
The system uses arrangement information about GUI item movement capabilities as feedback to determine the focus GUI movement direction. This feedback mechanism ensures that the focus GUI moves in a direction that is both consistent with wheel input and compatible with the permissible GUI item movement directions, preventing user confusion.
3Ease of operation
If the system identifies possible movement directions from arrangement information, then the user predictability is improved, but the device complexity increases
Solution Approach 1:
The system performs self-service by automatically identifying arrangement information about GUI item movement directions and using this information to determine focus GUI movement. This self-service mechanism improves user predictability without requiring additional user input or complex external processing, managing system complexity internally.

AI summary
An electronic device includes a display and a processor configured to control the display to display a user interface (UI) screen including a plurality of graphical user interface (GUI) items and a focus GUI, identify, based on a wheel input of a user, arrangement information about the plurality of GUI items, identify, based on the arrangement information, a possible movement direction of the focus GUI displayed at a location corresponding to one GUI item among the plurality of GUI items, based on the identified possible movement direction of the focus GUI including both a horizontal direction and a vertical direction, identify a movement direction of the focus GUI as the horizontal direction, and control the display to move the focus GUI based on a manipulation direction of the wheel input and the identified movement direction.
