Mobile Terminal Display Area Adjustment via Displacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for adjusting the display area of a web page on mobile devices either distort the content or lead to mis-operations, such as confusing hyperlink clicks with page dragging, due to limitations in scrolling and zooming mechanisms.
Innovation Solution
A method and apparatus that utilize a mobile communication terminal's displacement to adjust the display area by obtaining and processing displacement data, calculating new coordinates for the display origin point, and adjusting the page accordingly to prevent exceeding the permitted range, thereby maintaining the original page appearance and preventing mis-operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the browser re-typesets the web page to match the display screen width, then the display area is optimized for the screen, but the web page content becomes modified beyond recognition and confusing
Solution Approach 1:
Instead of re-typesetting the web page to fit the screen (modifying the page), the patent inverts the approach by keeping the page layout intact and adjusting the display area selection to match the screen dimensions. The display area is dynamically determined based on screen width and height, allowing the original page content to remain unchanged while achieving optimal display.
2Loss of information
If the web page is controlled to move by dragging on a touchscreen, then the original appearance is kept, but mis-operations are easily caused by confusion between dragging and clicking
Solution Approach 1:
The patent introduces a displacement sensor as an intermediary device to detect user input. Instead of directly interpreting touchscreen gestures (which can be ambiguous between dragging and clicking), the sensor detects displacement of the terminal device itself, providing clear unambiguous signals for page navigation without interfering with normal touchscreen interactions.
Solution Approach 2:
The patent replaces the mechanical touchscreen dragging operation with a sensor-based displacement detection system. By detecting the physical displacement of the terminal device through acceleration sensors or other displacement sensors, the system substitutes the ambiguous mechanical gesture with a precise sensor measurement, eliminating the confusion between different input types.
3Reliability
If displacement sensing is used to adjust display area, then mis-operations are prevented, but the system complexity increases due to additional sensor integration
Solution Approach 1:
The patent leverages the fact that modern mobile terminals already contain acceleration sensors for other functions (such as screen rotation, step counting, or gaming). By reusing these existing sensors for displacement detection in web page navigation, the patent avoids adding dedicated hardware while achieving reliable operation. The same sensor serves multiple purposes, reducing overall system complexity.

AI summary
The present invention discloses a method, an apparatus, and a terminal for adjusting a display area of a page. The method includes: obtaining displacement of a mobile communication terminal from a first time point to a second time point; and adjusting a display area of a currently browsed page according to the displacement. Through technical solutions of the present invention, a user may adjust the display area of the page through the mobile communication terminal, so as to solve a problem in the prior art that a mis-operation is easily caused when the display area of the page is adjusted in a manner of dragging on a touchscreen.
