Dual-Surface Touch Control for Mobile Terminal Screen Interaction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of mobile terminals face inconvenience in controlling visual information due to the need for repeated and diverse touch inputs to utilize and navigate through various functions on the display.
Innovation Solution
A mobile terminal equipped with a first and second touch sensor on opposite sides, allowing users to perform two-surface touch inputs to select and interact with specific regions of the screen, enabling simpler control of visual information and execution of functions without changing the primary screen information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple different types of touch inputs are applied repeatedly to control visual information, then the user can access various functions and information on the display, but the operation becomes complex and inconvenient
Solution Approach 1:
The patent introduces a new dimension for touch input by placing touch sensors on both the front surface and rear surface of the display. This allows users to perform two-surface touch inputs that correspond to specific regions on the display, enabling direct manipulation of visual information without complex input sequences. The spatial dimension of touch interaction is expanded from single-surface to dual-surface, simplifying the operation while maintaining versatility.
2Ease of operation
If a single touch sensor is used on the display, then the device structure remains simple, but the user cannot perform two-surface touch inputs to selectively access specific regions
Solution Approach 1:
The touch sensing functionality is segmented into multiple independent touch sensors positioned at different locations (front surface and rear surface). Each touch sensor can detect touches independently, and the controller processes these inputs to determine the corresponding display region. This segmentation enables precise region selection through two-surface touches while distributing the complexity across multiple simple sensor units.
Solution Approach 2:
The controller acts as an intermediary that receives touch inputs from multiple touch sensors and translates them into corresponding display region selections. It processes the coordinates from front and rear touch sensors, calculates the overlapping region, and triggers the appropriate display update. This intermediary layer manages the complexity of multi-sensor coordination without requiring complex hardware architecture.
3Adaptability or versatility
If the display shows only primary screen information, then the information presentation remains simple, but the user cannot access additional information or functions without changing the primary screen
Solution Approach 1:
The system prepares secondary images containing additional information or functions in advance, associated with specific regions of the primary screen. When a user performs a two-surface touch on a particular region, the corresponding pre-prepared secondary image is displayed without requiring the user to navigate away from the primary screen. This preliminary preparation of secondary content enables instant access to additional information while maintaining the primary display context.
