Touchscreen UI Adaptation for Hand Position Comfort
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional touchscreen entry systems are limited in providing additional interfaces to users as they rely solely on touch coordinates, leading to discomfort, especially for left-handed users due to UIs primarily designed for right-handed individuals, where the touchscreen may be hidden by the left hand.
Innovation Solution
An electronic device method that detects a region and position adjacent to a touch input on the touchscreen, adjusting the user interface display based on the relative relation between the touch input, adjacent region, and adjacent position to enhance user comfort and accessibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional touchscreen entry systems recognize only coordinates of touches on the screen, then the system structure remains simple, but the user interface cannot be dynamically adjusted to accommodate different user preferences and hand positions
Solution Approach 1:
The system performs preliminary detection of the user's hand position and body orientation before presenting the user interface. By detecting the adjacent region and position where the user's body or object is positioned relative to the touchscreen, the system proactively configures the UI layout to match the user's natural holding position, rather than requiring post-detection adjustments
Solution Approach 2:
The user interface is made dynamic by continuously adjusting its layout and element positions based on real-time detection of touch input location and adjacent region information. The UI configuration changes dynamically according to the detected hand position, making the interface adaptable to different users and usage scenarios without requiring manual reconfiguration
2Ease of operation
If the user interface is primarily designed for right-handed users, then the design process is simplified, but left-handed users experience discomfort as the touchscreen may be hidden by their left hand
Solution Approach 1:
The system introduces asymmetry in UI layout by detecting the user's hand position and body orientation. Instead of using a fixed symmetric layout optimized for right-handed users, the interface elements are asymmetrically positioned based on the detected adjacent region, creating a customized layout that accommodates both right-handed and left-handed users equally well
Solution Approach 2:
Different regions of the touchscreen are assigned different functions based on the detected user hand position. The system identifies which region is more accessible to the user (adjacent to the user's body or held object) and optimizes the placement of interactive elements in that specific local region, rather than using a uniform distribution across the entire screen
3Ease of operation
If the user interface elements are fixed in position, then the interface design is straightforward, but users cannot access elements comfortably when holding the device in different positions
Solution Approach 1:
The system determines the optimal position for UI elements before displaying them, based on preliminary detection of the user's hand position and device holding orientation. By calculating the adjacent region and position in advance, the system pre-configures the UI layout to maximize element accessibility, rather than adjusting positions after the user has already struggled to reach elements

AI summary
According to an embodiment of the present disclosure, a method and an electronic device for receiving a user input by the electronic device is provided. The method includes receiving a first touch input on a touchscreen, detecting at least part of a region contacted by the first touch input on the touchscreen, a region adjacent to the contacted region, and a position adjacent to the contacted region, after receiving the first touch input, and displaying a user interface on the touchscreen at least partially based on a relative relation between the region contacted by the first touch input, and at least one of the adjacent region and the adjacent position.
