Dynamic Touch Interface Layout for Mobile Terminal Operability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile terminals with touch panel displays face operability issues due to the inability to adjust the positions of operational objects in accordance with the user's holding style, limiting intuitive operation.
Innovation Solution
The information processing terminal includes a display input unit, detecting unit, and control unit that adjust the positions of operational objects based on how the terminal is held, using setting areas for both one-handed and two-handed use, and incorporating touch operations to move icons to optimal positions for enhanced usability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the terminal uses a fixed display layout for operational objects, then the device complexity is reduced, but the ease of operation deteriorates because the positions cannot be adjusted to match different holding styles
Solution Approach 1:
The display layout is made dynamic by automatically detecting the terminal's rotation angle and adjusting the positions of operational objects accordingly. The control unit receives rotation angle information from the rotation detecting unit and dynamically repositions icons and buttons to optimize usability for different holding styles (one-handed or two-handed), transforming a static layout into an adaptive one.
Solution Approach 2:
The system implements feedback by continuously monitoring the terminal's rotation angle through the rotation detecting unit and using this information to adjust the display layout. The control unit processes the rotation angle information and automatically modifies operational object positions, creating a closed-loop system that responds to user holding behavior.
2Ease of operation
If the terminal adjusts operational object positions based on rotation angle, then the ease of operation improves, but the device complexity increases due to additional detecting and control units
Solution Approach 1:
The rotation detecting unit serves multiple functions: it detects the terminal's rotation angle for layout adjustment, identifies whether the terminal is being held one-handed or two-handed, and provides orientation information for optimizing operational object positions. This multi-functionality reduces the need for separate dedicated components for each function.
Solution Approach 2:
The control unit automatically adjusts operational object positions based on rotation angle information without requiring manual user input or configuration. The system self-adapts to different holding styles by processing rotation data and autonomously repositioning icons and buttons, eliminating the need for user intervention in the adjustment process.
3Ease of operation
If all operational objects are moved to the touched setting area, then the ease of operation improves for the touched area, but unnecessary object movement occurs affecting other areas
Solution Approach 1:
Instead of uniformly moving all operational objects to the touched setting area, the system applies local quality by selectively moving only the necessary operational objects to the touched area while leaving others in their original positions. The control unit determines which objects should be relocated based on the touched setting area's position and the terminal's rotation angle, optimizing accessibility without causing unnecessary movements.

AI summary
To provide an information processing terminal capable of solving the problem in which the positions of operational objects cannot be adjusted in accordance with the holding style so as to improve operativity. A display input unit has a display screen and receives a touch operation made to the display screen. A detecting unit detects a position at which the touch operation has been made on the display screen. A control unit displays operational objects or icons on the display screen. The control unit also moves icons to an icon gathering area in accordance with the number of detected areas among a plurality of setting areas set up in the display screen, or the setting areas including an operated position detected by detecting unit 2.
