Mobile Terminal 3D Icon Depth Control via Touch Gestures
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile terminals face challenges in effectively displaying 3D images and managing 3D display levels for object icons, lacking a seamless method to adjust the perceived depth and interaction with users through intuitive touch gestures.
Innovation Solution
A mobile terminal with a touchscreen and controller that allows users to set and adjust 3D display levels for object icons by interpreting touch actions, enabling icons to be projected or recessed based on specific touch patterns, thereby enhancing user interaction and visual representation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If 3D display levels are adjusted for object icons, then visual depth perception is improved, but device complexity increases
Solution Approach 1:
The patent adjusts the 3D display level by changing the Z-coordinate parameter of object icons in the rendering scene. This allows dynamic control of visual depth perception through parameter modification rather than hardware changes, resolving the contradiction between improved visual depth and device complexity
Solution Approach 2:
The patent introduces a Z-axis dimension to the traditional 2D display coordinate system, enabling objects to be positioned at different depths. This dimensional extension achieves enhanced visual depth perception while maintaining the same physical display device, avoiding complexity increases
2Ease of operation
If touch actions are used to control 3D display levels, then ease of operation is improved, but measurement precision deteriorates
Solution Approach 1:
The patent implements feedback mechanisms where the system monitors touch actions and automatically adjusts the 3D display level accordingly. The controller detects touch patterns and translates them into precise Z-coordinate adjustments, providing both ease of operation through intuitive touch and measurement precision through automated control algorithms
Solution Approach 2:
The patent introduces a controller as an intermediary between the touch input and the rendering system. This mediator translates rough touch gestures into precise 3D level adjustments, resolving the contradiction by decoupling the user's ease of operation from the precision requirements of the measurement and control system

AI summary
A mobile terminal and a method of displaying 3D images thereon are disclosed. A display module in a mobile terminal may include a touchscreen and a controller. The touchscreen may be configured to display a plurality of icons and to receive a touch input that sets a 3D display setting for at least one of the icons. The controller may be configured to set the 3D display setting according to a pattern of the touch input. The touch pattern may determine whether the displayed 3D image of the icon is perceived to project or recede into the touch screen and/or a magnitude of a projection or recession.
