Dynamic Touch Interaction for Mobile Display Detail Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mobile terminals with touch screens face challenges in displaying detailed information for selected areas due to limited screen size, requiring multiple touch input steps to access subordinate content, which is inconvenient and reduces content visibility.
Innovation Solution
A method and apparatus for controlling detailed information display using dynamic touch interaction, allowing users to display subordinate content within a selected area by executing a stipulated touch input with two touch points, which analyzes and recognizes touch inputs to control the display of detailed point-of-interest information based on depth levels, enabling easy access to detailed information without cumbersome inputs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If the screen size is reduced to improve portability, then the mobile terminal becomes more portable, but the visible content area and detail information display are reduced
Solution Approach 1:
The patent introduces a new interaction dimension by using two-finger touch gestures with varying distances to access different depth levels of information. Instead of expanding the physical screen area, the solution creates virtual depth layers through multi-dimensional touch input, allowing users to navigate from overview level to detailed information level without increasing screen real estate.
2Device complexity
If multiple touch input steps are required to access subordinate information, then information hierarchy can be maintained, but user convenience and accessibility are reduced
Solution Approach 1:
The patent implements dynamic touch interaction where the system responds differently based on the real-time state of user input. The two-finger distance dynamically adjusts the level of information displayed, and the interaction continues smoothly as users adjust their finger spacing. This dynamic response eliminates rigid multi-step processes while maintaining clear information hierarchy through continuous feedback.
Solution Approach 2:
The system automatically interprets the user's intent based on the two-finger distance and displays the appropriate level of information without requiring explicit commands or navigation through multiple menus. The touch gesture itself carries the complete instruction set, and the system self-adjusts the displayed content based on the gesture parameters.
3Area of stationary object
If detailed information is displayed for the entire screen, then all content is visible, but the focus on selected areas and subordinate content is lost
Solution Approach 1:
The patent applies different levels of detail to different regions of the display based on user selection. When a user performs a two-finger gesture on a specific area, that local region expands to show detailed information while other areas maintain their overview state. This creates a focused viewing experience where subordinate content receives appropriate attention without requiring the entire screen to display maximum detail.
Data Source
AI summary
A method and apparatus configured to control the level of detailed information displayed for a selected area using a dynamic touch interaction in a mobile terminal including a touch screen, are provided. The apparatus include a memory that stores contents to be output through the touch screen as data, a touch interaction module that analyzes a user's touch input through the touch screen and recognizes a stipulated touch interaction, and a control unit that controls an overall operation of the apparatus according to the user's input through the touch screen. The control unit also controls the level of subordinate detailed information displayed in an area, which is designated by the user through a stipulated touch input, to be displayed when the stipulated touch input is recognized through the touch interaction module, based on the data stored in the memory.
