Target Element Zoom Focal Point Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in zooming in on elements within a web page without losing their orientation due to changes in the layout, as existing zoom operations often relocate the focal point within the display area.
Innovation Solution
A target element zoom component that performs a focal point zoom operation using an appropriate zoom factor, allowing the target element to remain within the display area with the focal point retained, which is determined via two-finger tap input on a touch-enabled device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a user zooms in on an element on a web page, then the element becomes larger and easier to see, but the element changes its location relative to the web browser window causing users to lose their place and become disoriented
Solution Approach 1:
The patent applies local quality by making different parts of the interface behave differently during zoom operations. Specifically, the focal point area maintains its position while other elements can adjust, creating a localized stability zone that preserves user orientation while still allowing magnification of the target element.
Solution Approach 2:
The system performs preliminary action by calculating and setting the focal point position before the zoom operation begins. This pre-establishment of the focal point ensures that the element remains anchored at the expected location during zooming, preventing disorientation while achieving magnification.
2Area of moving object
If a zoom operation is performed on a target element, then the element size increases for better viewing, but the layout of the page changes causing the element to relocate within the display area
Solution Approach 1:
The patent implements local quality by applying different transformation properties to different parts of the page layout. The target element and its immediate vicinity undergo magnification while the focal point position remains fixed, creating a localized stable region that maintains position stability for critical elements while allowing overall size increase.
Solution Approach 2:
The system segments the page into different zones with different zoom behaviors: a focal point zone that maintains fixed position, a target element zone that magnifies, and surrounding areas that may adjust accordingly. This segmentation allows the target element to increase in size while the focal point remains stable.
3Ease of operation
If the focal point is retained during zoom operation, then user orientation is maintained, but the zoom factor must be limited to keep the element within the display area
Solution Approach 1:
The patent applies dynamics by making the zoom factor adaptive rather than fixed. The system dynamically calculates the maximum feasible zoom factor based on the element's position, size, and the display area constraints while maintaining focal point stability. This allows the zoom level to adjust automatically, providing both user orientation and adequate zoom capability within available space.
Solution Approach 2:
The system changes parameters dynamically by adjusting the zoom factor based on real-time calculations of element position and display boundaries. Rather than offering fixed zoom levels, the system modifies the zoom parameter adaptively to maximize magnification while keeping the element within the display area and maintaining focal point retention.

AI summary
Various embodiments provide a target element zoom component that is configured to perform a focal point zoom operation on a target element using an appropriate zoom factor. In at least some embodiments, the target element zoom component receives a request to perform a zoom operation at a focal point of a target element in a page displayed in a display area. In at least some embodiments, the request is received via two-finger tap input on a screen of a touch enabled device. The target element zoom component then determines an appropriate zoom factor for the zoom operation. Responsive to determining the appropriate zoom factor, the target element zoom component performs the zoom operation on the page using the appropriate zoom factor so that the target element remains within the display area with the focal point retained.
