Touchscreen Zoom Threshold Logic for Content Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable electronic devices lack an efficient method to seamlessly transition between primary content magnification levels and related additional information items based on user input, often overwhelming users with irrelevant data when zooming out.
Innovation Solution
An apparatus and method that utilize a touchscreen to respond to zoom commands by determining if the magnification level exceeds a threshold, displaying additional information items only when beyond this level, and allowing a single user input (pinch gesture) to correspond to both zoom-in and zoom-out commands, thereby managing content display effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the magnification level is increased beyond a threshold when zooming out, then more additional information items can be displayed, but the screen becomes cluttered with irrelevant data
Solution Approach 1:
The system changes the parameter of magnification level to control the quantity of additional information items displayed. When the magnification level exceeds a threshold during zoom-out operation, the system stops displaying more additional information items, thereby maintaining screen clarity while providing sufficient information at appropriate magnification levels.
2Ease of operation
If multiple separate user inputs are required for zoom-in and zoom-out commands, then precise control is achieved, but user interaction complexity increases
Solution Approach 1:
The touchscreen interface is designed to recognize multiple types of zoom commands (tap, double-tap, pinch gestures) through a single unified interaction mechanism. This allows the same input device to perform multiple functions (zoom-in, zoom-out, adjust magnification level) without requiring separate control mechanisms, thereby simplifying user interaction while maintaining precise control.
3Loss of information
If additional information items are always displayed when zooming out, then information accessibility is improved, but user attention is分散ed
Solution Approach 1:
The system uses magnification level as a control parameter to regulate information accessibility. Additional information items are displayed only when the magnification level exceeds a specific threshold during zoom-out operation. This conditional display mechanism ensures that information is accessible when needed (at appropriate zoom levels) while preventing information overload that would distract user focus at normal viewing magnification.

AI summary
Apparatus comprises at least one processor and at least one memory, having stored thereon computer-readable code, the at least one processor being configured under the control of the computer-readable code to cause primary content to be displayed on a display with a first magnification level, to be responsive to an indication of a receipt of a first zoom command, the first zoom command being for causing alteration of the magnification level from the first magnification level to a second magnification level, to determine if the second magnification level is beyond a threshold magnification level, if it is determined that the second magnification level is not beyond the threshold magnification level, to cause the primary content to be displayed on the display with the second magnification level, and if it is determined that the second magnification level is beyond the threshold magnification level, to cause a first set of one or more additional information items relating to the primary content to be displayed on the display in addition to the primary content.
