Touch Screen Input Control Region Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Digital portable terminals face limitations in size due to the need for separate control buttons, restricting the size of the touch input device on small devices.
Innovation Solution
A touch screen method and terminal design that integrates data input and control functions within a single display area, recognizing different touch manners for inputting data and activating control functions, and providing user guidance through prompts, allowing the touch input area to function as both input and control region.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate control buttons are added to the terminal, then control functionality is improved, but the device size increases
Solution Approach 1:
The patent merges the control region and data input area into a single integrated touch input interface. The display area simultaneously serves as both the control interface (with graphic icons) and the data input region, eliminating the need for separate control buttons while maintaining full control functionality.
Solution Approach 2:
The touch input area is designed to perform multiple functions: it displays graphic icons for control, accepts data input through writing gestures, and responds to different touching manners (single touch, double touch, long press) to activate various control functions. This multi-functional design replaces dedicated control buttons with a universal touch interface.
2Area of moving object
If the touch input device size is increased, then data input capability is improved, but the device becomes less portable
Solution Approach 1:
The control region is merged with the data input area, allowing the entire display area to function as the touch input interface. This integration maximizes the effective touch input area without requiring additional physical space beyond the display itself, thereby improving data input capability while maintaining device portability.
3Device complexity
If the control region is used for both control and data input, then device complexity is reduced, but touch recognition accuracy may deteriorate
Solution Approach 1:
The system dynamically adapts the function of different regions based on the touching manner detected. During data input mode, the control region is dynamically converted into an additional data input area, while during normal operation it serves as the control interface. This dynamic functionality resolution allows the same physical region to serve multiple purposes without compromising touch recognition accuracy.
Solution Approach 2:
The patent changes the operational parameters of the touch input area based on the detected touching manner. Different touching patterns (single touch, double touch, long press, writing gestures) trigger different functional modes, allowing the system to distinguish between control commands and data input actions even within the same physical region, thereby maintaining both simplicity and recognition accuracy.
Data Source
AI summary
A mobile terminal having a touch screen is disclosed. The terminal includes a touch input unit and a control unit. The touch input unit provides a touch input area for inputting data information, a display area for displaying the input data information and a control region for inputting control commands, wherein the touch input area overlaps with the display area and/or the control region. The control unit controls the input and display of the information through the touch input and display area according to the control commands input through the control region.
