Motion Sensing Page Control for Portable Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In portable terminals, controlling a page movement through slide operations on the screen can lead to error operations and shields the display area, making it difficult for users to view or edit content outside the screen area.
Innovation Solution
A display method and device that utilize motion sensing to detect and calculate a second motion vector for the page, allowing it to move on the screen without requiring user touch input, thereby avoiding errors and maintaining visibility of on-screen content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If page movement is controlled according to slide operation on the screen by user's finger, then the page can be moved to view outside display area, but the user's finger cannot leave the screen which changes cursor location easily or causes error operation
Solution Approach 1:
The patent replaces the mechanical touch-based slide operation system with a motion sensing system. The motion sensing unit detects the movement of the portable terminal itself, and the processor translates this physical movement into page scrolling actions, eliminating the need for direct finger contact with the screen while maintaining reliable operation control
2Ease of operation
If page movement is controlled according to slide operation on the screen, then the page can be moved, but it causes shield for the display area and affects the user watching contents of the page within the display area during the moving
Solution Approach 1:
By substituting the touch-based slide operation with motion sensing, the patent eliminates the hand overlaying over the display area. The user holds the terminal stationary while the system detects motion through the motion sensing unit, preventing the hand from shielding the display and allowing full visibility of page contents during movement
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Effectively prevents error operations during page movement and maintains the visibility of on-screen content by using motion sensing to control page movement, enhancing user experience and interaction with portable terminals.
Implementation Method 1
a motion sensing unit, configured to detect a motion vector of the portable terminal

AI summary
There are provided a display method and a display device in a portable terminal, the display method including: in a predetermined display mode, detecting a first motion vector of the portable terminal; calculating a second motion vector of a page currently displayed on a screen of the portable terminal based on the first motion vector of the portable terminal; and controlling the page to move on the screen according to the calculated second motion vector. By adopting the display method and the display device in the portable terminal according to the exemplary embodiment of the present disclosure, a page displayed on a screen of the portable terminal may be controlled to move through a motion sensing operation, thereby avoiding a touch operation for the screen during controlling the page to move.
