Touchscreen Display Region Size Control via Dynamic Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable terminals with touchscreens face challenges in efficiently controlling display region sizes due to differences in operation methods compared to devices with separate input devices, necessitating a solution for intuitive size adjustment and multitouch functionality.
Innovation Solution
A method and apparatus for controlling the size of a display region in a portable terminal with a touchscreen, involving a control unit that determines a size control amount based on touch information during size change events and adjusts the display region accordingly, allowing for single-touch and multitouch operations to modify display size and direction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a touchscreen is used to increase display area by removing separate input devices, then display size is improved, but user interface complexity increases due to different operation methods
Solution Approach 1:
The touchscreen serves multiple functions: it acts as both the display screen and the input device, replacing traditional separate components like keypads and buttons. This multi-functionality allows the device to maintain a larger display area while managing interface complexity through unified interaction paradigms.
Solution Approach 2:
The user interface employs dynamic behavior where the same touchscreen can operate in different modes (touch input, display output, gesture recognition) depending on the operational context. This dynamic adaptability allows the system to handle various operations through a single interface, reducing the perceived complexity despite the multifunctional nature.
2Loss of information
If display region size is increased to show more information, then information display capability is improved, but power consumption increases
Solution Approach 1:
The display region size is made dynamic rather than fixed. The system can adjust the active display area based on the current operational needs and information density requirements. When full display area is not necessary, the system reduces the active display region to minimize power consumption while maintaining adequate information display capability.
Solution Approach 2:
The patent changes the parameter of display region size dynamically. By adjusting this parameter based on operational context, the system optimizes the balance between information display capability and power consumption, displaying larger regions only when necessary for the current task.
