Dynamic Index Interface for Digital Device Content Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Digital devices struggle to effectively display and manage index information, particularly in scenarios where multiple related contents cannot be shown on a single screen, and there is a need to dynamically adjust the interface based on user input and content properties.
Innovation Solution
A digital device equipped with a display unit, touch sensor unit, and processor that allows the interface to change shape and index order based on slide touch inputs, enabling the display of contents in different sequences and regions, and adjusting the layout to accommodate user interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If multiple related contents are displayed on one screen, then information density is improved, but display area and visual clarity deteriorate
Solution Approach 1:
The interface is segmented into multiple functional regions: a first region displaying a plurality of objects (index information) and a second region displaying content details. This segmentation allows simultaneous display of multiple contents while maintaining adequate display area for each, resolving the contradiction between information density and visual clarity.
2Ease of operation
If index information is displayed in a fixed sequence, then navigation simplicity is improved, but adaptability to different user preferences deteriorates
Solution Approach 1:
The index order is made dynamic rather than fixed. The processor changes the display sequence of objects in the first region based on detected slide touch inputs, allowing the interface to adapt to user preferences while maintaining simple navigation through touch-based control.
3Adaptability or versatility
If the interface shape is changed based on touch input, then user interaction flexibility is improved, but interface complexity deteriorates
Solution Approach 1:
The shape of the first region is made dynamic, changing from a linear arrangement to a curved arrangement based on slide touch inputs. This dynamic shape adjustment provides flexible user interaction while the curvature parameter controls the degree of change, preventing excessive complexity.
Solution Approach 2:
The interface shape is controlled by changing geometric parameters (curvature radius) rather than fundamentally redesigning the interface structure. This parameter-based approach allows flexible shape adjustment while maintaining interface simplicity through controlled transformation.

AI summary
A digital device and a method for controlling the same are disclosed. The method for controlling a digital device comprises the steps of displaying contents and a first interface scrolling the contents in a first shape; displaying a plurality of objects included in the first interface based on a first index order; detecting a first slide touch input moving in a first direction on the first interface; scrolling a plurality of contents based on the first direction; detecting a second slide touch input moving in a second direction on the first interface; displaying the first interface in a second shape; and displaying the plurality of objects included in the first interface based on a second index order.
