Side Display Region Virtual Key Selection for Mobile Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The user interface for touch input mechanisms in mobile terminals has not evolved significantly despite changes in screen size, ratio, and user environment, making it difficult for users to easily select virtual keys and perform repeated actions while maintaining a grip on the device.
Innovation Solution
A terminal with a side display region and a controller that determines actions performed, displays virtual keys on the side region based on user input, and recognizes touch regions to facilitate input, allowing users to easily select virtual keys and perform actions without releasing the device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If virtual keys are displayed on the main display region, then users can access various functions, but users cannot easily select virtual keys while maintaining a grip on the device
Solution Approach 1:
The display is divided into a main display region and a side display region. The side display region is further segmented into multiple sub-regions that can independently display different virtual keys or interfaces. This segmentation allows users to access frequently used functions on the side display without needing to navigate through the main display, enabling one-handed operation while maintaining grip on the device.
2Area of stationary object
If the display size increases, then more information can be displayed, but the user interface for touch input has not evolved and selection becomes difficult
Solution Approach 1:
Different regions of the display are assigned different functions and interface qualities. The side display region specifically displays virtual keys and controls optimized for thumb or finger access, while the main display region shows primary content. This local quality differentiation ensures that frequently touched elements are positioned in easily accessible areas, maintaining ease of operation despite increased overall display size.
3Area of stationary object
If physical keys are removed to increase display size, then the terminal becomes more modern, but touch input mechanisms become less intuitive
Solution Approach 1:
The interface transitions from a traditional two-dimensional flat display to a more spatial arrangement by utilizing the side display region. Virtual keys are positioned at different locations including the side region, creating a multi-zone input experience that mimics the spatial distribution of physical keys while maintaining the advantages of a large touchscreen display.
