Touch Screen Object Selection via Dynamic Repositioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable mobile terminals with touch screens face challenges in accurately selecting objects due to overlapping or adjacent items on limited screen sizes, leading to touch faults and poor user experience.
Innovation Solution
A display processing method that determines a touch point and a predetermined area, then moves overlapping or adjacent objects to new positions, ensuring the edge extension areas do not intersect, thereby facilitating user selection by increasing the distance between objects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If multiple objects are displayed on a limited-size touch screen, then the information density is improved, but the accuracy of object selection deteriorates due to overlapping or adjacent objects
Solution Approach 1:
The patent applies dynamics by making the object positions changeable and adjustable. Objects can be moved from their original positions to new positions dynamically, allowing the interface to adapt to user interaction needs. This resolves the contradiction by enabling high information density in the initial state while allowing dynamic separation when selection accuracy is needed.
Solution Approach 2:
The patent changes the position parameter of objects on the touch screen. By modifying the coordinates and spatial relationships of objects, the system maintains high information density while enabling accurate selection through parameter adjustment. Objects are moved based on calculated positions that optimize both density and selectability.
2Ease of operation
If objects are moved to increase distance between them, then the ease of selection is improved, but the area occupied by objects increases
Solution Approach 1:
The patent utilizes multi-dimensional spatial arrangement and projection techniques. Objects are positioned in a way that considers multiple dimensions of the touch screen space, optimizing both separation distance and area utilization. This allows improved selection ease without excessive area occupation by efficiently using available screen real estate across different spatial dimensions.
Solution Approach 2:
The system adjusts positional parameters of objects to optimize the balance between selection ease and area occupation. By calculating optimal positions that maintain reasonable distances while minimizing total area used, the patent resolves the contradiction between ease of operation and area efficiency.
3Measurement precision
If the touch screen size is increased to reduce object overlap, then the object selection accuracy is improved, but the portability of the terminal deteriorates
Solution Approach 1:
Instead of increasing screen size, the patent makes the object arrangement dynamic. Objects can be repositioned and adjusted based on interaction context, providing selection accuracy comparable to larger screens while maintaining the compact form factor required for portability.
Solution Approach 2:
The patent changes the positional parameters of objects to optimize selection accuracy within the constrained screen size. By adjusting coordinates, distances, and spatial relationships, the system achieves accurate selection without increasing the physical dimensions of the touch screen, thus preserving terminal portability.

AI summary
A display processing method that is applied in a portable mobile terminal, to display multiple objects on a touch screen of the portable mobile terminal. The method includes obtaining a touch point that is a point created when an operating object contacts/almost touches the touch screen; determining a preset area with the touch point being the center; determining a first object and a second object, among multiple objects, each intersecting with the preset area on at least one point; determining a first information of the movement of the first object, the first information indicating moving the first object from a first position to a second position, the first position being the original position of the first object displayed on the touch screen; and moving the first object from the first position to the second position according to the first information.
