Touch Area Positioning for Overlap Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In electronic apparatuses with touch panel displays, the touch areas at the corners of objects become excessively close during contraction, leading to overlap and difficulty in individual operation, especially when the image is reduced further.
Innovation Solution
The solution involves setting multiple touch areas that change their intervals and display positions dynamically during expansion and contraction operations, ensuring the touch areas do not overlap by recalculating their coordinates to maintain a predetermined gap, thereby improving operability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the image is contracted by narrowing the touch areas, then the display size is reduced, but the touch areas become adjacent or overlap making individual operation difficult
Solution Approach 1:
The patent applies dynamics by making the touch area positions adjustable and adaptive. When contraction is detected, the system dynamically repositions touch areas to prevent overlap while maintaining the contracted display size. This allows the system to adapt the touch area configuration based on the current display state, resolving the contradiction between small display size and operability.
Solution Approach 2:
The patent changes the parameter of touch area position based on the contraction state. By detecting the interval between touch areas and adjusting their positions accordingly, the system maintains optimal operability across different display sizes. This parameter adjustment ensures that touch areas remain separable and operable even when the display is highly contracted.
2Length of moving object
If the touch areas are moved close together to reduce display size, then the contraction function is achieved, but the touch areas become excessively close and may overlap
Solution Approach 1:
The patent implements feedback by continuously monitoring the interval between touch areas and adjusting their positions based on this feedback. When the interval becomes too small, the system detects this condition and repositions the touch areas to maintain a reliable distinction. This feedback mechanism ensures that touch areas remain operable while achieving the desired contraction.
Solution Approach 2:
The patent applies preliminary action by proactively adjusting touch area positions before overlap occurs. By detecting when touch areas approach each other too closely, the system preemptively repositions them to maintain adequate separation. This preliminary adjustment prevents overlap and ensures continuous operability during contraction operations.

AI summary
A control device for an electronic apparatus including a touch panel display, in which it receives touch operations by setting a predetermined area as a touch area, a display size of an object displayed on the touch panel display is changed by setting a plurality of expanding touch areas as operations with respect to a function of expansion and contraction, and touch-operating intervals of the plurality of expanding touch areas, and the display position of the touch area is changed so as to widen the intervals when a touch operation for narrowing the intervals between the plurality of expanding touch areas more than a predetermined amount is performed.
