Mobile Terminal One-Hand Mode Screen Layout
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile terminals face challenges in allowing users to efficiently operate the entire touch screen with one hand, as the screen size and hand size limitations restrict the operable area, necessitating a method to utilize the entire screen effectively in one hand mode.
Innovation Solution
A mobile terminal with a controller that divides the touch screen into a view area and a control area in response to user input, allowing the user to switch between modes by adjusting the layout of keypads, application screens, and other interfaces to optimize one-hand operation, including outputting a simple keypad, conversation information, or editing areas on the control area and magnifying the view area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the mobile terminal uses a large touch screen to provide comprehensive functionality, then the screen area is increased, but the operable area with one hand is restricted
Solution Approach 1:
The touch screen is divided into two distinct areas: a view area that displays content and a control area that accepts user input. This segmentation allows the full screen to be utilized while ensuring that the control area remains accessible to one hand, resolving the contradiction between large screen area and one-hand operability.
Solution Approach 2:
The patent introduces a spatial dimensionality change by separating the screen into view and control areas. The control area is positioned in a location that is easily accessible to one hand (typically the bottom or side portion), while the view area occupies the remaining space. This dimensional reorganization enables comprehensive screen utilization without compromising one-hand operation.
2Ease of operation
If the screen is outputted to a partial area only to accommodate one hand operation, then the one-hand operability is improved, but the screen utilization efficiency is reduced
Solution Approach 1:
By segmenting the screen into view area and control area, the patent enables the user to operate the terminal with one hand on the control area while the view area displays content. This segmentation allows full screen utilization without sacrificing one-hand operability, eliminating the need to reduce screen output to a partial area only.
Solution Approach 2:
The control area serves multiple functions including receiving user input, displaying control-related information, and providing access to various applications. This multi-functionality maximizes screen utilization efficiency while maintaining one-hand operability, as the control area consolidates multiple operational needs in a compact, accessible location.
3Illumination intensity
If the default keypad is displayed on the entire touch screen in one hand mode, then the keypad visibility is improved, but the control precision is reduced
Solution Approach 1:
The keypad is segmented and displayed only on the control area rather than the entire touch screen. This segmentation maintains keypad visibility within the accessible control area while improving control precision by limiting the keypad to a region that is easily reachable and operable with one hand, preventing users from needing to reach across the entire screen.
