Dynamic Magnified View Window for Touch Panel Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Touch panel electronic devices face challenges in selecting small characters due to difficulty in recognizing the selected portion, as it is often hidden under the finger, and existing magnification technologies have fixed sizes that do not adapt to finger movement.
Innovation Solution
An electronic device with a magnified view window that dynamically enlarges in size based on the movement of the touched position, allowing a broader area to be displayed, including the post-moving touched position, facilitating easier recognition of the selected portion by adjusting its size and position accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a fixed-size magnified view window is displayed to show the selected portion, then the selected portion becomes visible, but the window size cannot adapt when the finger moves to a new position
Solution Approach 1:
The magnified view window dynamically changes its size based on the movement of the touched position. When the user moves their finger to a new position, the system calculates the movement distance and adjusts the window size accordingly, transforming the static fixed-size window into a dynamic adaptive window that responds to user interaction.
Solution Approach 2:
The system changes the size parameter of the magnified view window based on the touched position movement. By calculating the Euclidean distance between the first touched position and the second touched position, the system adjusts the window size parameter to provide an appropriate magnified view of the selected area.
2Loss of information
If the magnified view window size is enlarged to show more area, then the selected portion remains visible during finger movement, but the device complexity increases
Solution Approach 1:
The system implements feedback by continuously monitoring the touched position changes and automatically adjusting the magnified view window size in response. The calculation unit computes the movement distance between the first and second touched positions, and the display unit responds by enlarging or shrinking the window accordingly, creating a closed-loop adaptive system.
Solution Approach 2:
The magnified view window system serves itself by automatically adjusting its own size based on the touched position movement without requiring additional user input. The system uses the finger movement data to self-regulate the window dimensions, making the adaptation process autonomous and reducing overall system complexity.
