Dynamic Icon Layout for One-Handed Mobile Device Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of large-screen mobile devices and tablet PCs often need to use one hand to hold the device and another hand to operate application icons or virtual buttons, leading to suboptimal user experience due to the fixed arrangement of these icons or buttons.
Innovation Solution
A terminal device equipped with first and second sensing units, such as gravity sensors or gyroscopes, positioned within the housing to collect acceleration or angular velocity information, which a processing unit uses to determine how the user holds the device, allowing for dynamic rearrangement of application icons or virtual buttons based on the user's holding manner.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple application icons or virtual keys are provided on touch screens, then the functionality of the terminal device is improved, but the ease of operation deteriorates when the user holds the device with one hand
Solution Approach 1:
The patent implements dynamic rearrangement of application icons and virtual buttons based on real-time detection of user holding manner through sensing units. The layout transitions from static to dynamic, automatically adjusting icon positions and sizes according to whether the device is held in one hand or two hands, thereby resolving the contradiction between maintaining comprehensive functionality and ensuring ease of operation
Solution Approach 2:
The patent applies local quality by making different regions of the touch screen have different properties based on holding detection. When one-hand holding is detected, icons in the thumb-reachable area are enlarged and positioned optimally, while other areas are adjusted accordingly. This localized optimization ensures ease of operation in the critical interaction zone while preserving overall device functionality
2Area of stationary object
If the terminal device has a large screen, then the display quality is improved, but the ease of operation deteriorates due to the need to use both hands
Solution Approach 1:
The patent makes the interface layout dynamic by continuously monitoring device orientation and holding manner through gravity sensors and gyroscopes. Based on this data, the system automatically adjusts icon sizes, positions, and densities to optimize one-hand accessibility while preserving the full display area, thus resolving the contradiction between large screen real estate and ease of operation
Solution Approach 2:
The patent utilizes the spatial dimension by analyzing the three-dimensional orientation and rotation of the device through multiple sensing units. By detecting the device's spatial posture and inferring holding manner from orientation data, the system can dynamically adjust the two-dimensional layout of icons and buttons to match the user's physical interaction context, enabling one-hand operation on large screens
