Mobile Terminal Page Navigation via Gesture Duration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile terminals lack intuitive user interfaces for navigating electronic documents, failing to replicate the experience of flipping through physical book pages, and thus require a new input method for controlling operations related to electronic documents.
Innovation Solution
A mobile terminal using combinations of touch, drag, and flicking inputs to control page navigation, where the duration and direction of inputs determine the number of pages to turn, simulating the gesture of flipping physical pages, and allowing users to jump or drag through electronic documents.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional key or touch input methods are used for navigating electronic documents, then the mobile terminal can perform basic page navigation functions, but the user interface lacks intuitiveness and fails to provide the experience of flipping physical book pages
Solution Approach 1:
The patent applies the copying principle by replicating the physical book page-flipping experience in the digital environment. The system detects drag gestures on the display screen and responds by animating page turns that visually mimic the physical action of pulling and turning paper pages, complete with realistic effects like page curling and shadow transitions. This creates an intuitive interface that copies the familiar physical interaction pattern.
Solution Approach 2:
The patent replaces conventional mechanical or simple touch input methods with a gesture-based control system that detects drag movements. Instead of using physical buttons or simple tap commands, the system uses touch screen gesture recognition to detect the direction, distance, and speed of user drags, then translates these gestures into corresponding page navigation actions, substituting mechanical input with software-based gesture processing.
2Productivity
If users navigate through electronic documents page by page using conventional methods, then navigation is straightforward, but the process is time-consuming and lacks efficiency for accessing distant pages
Solution Approach 1:
The patent applies dynamics by making the page-turning process adaptive and continuous rather than discrete and static. The system dynamically adjusts the page navigation based on the user's drag gesture characteristics - the distance, speed, and duration of the drag determine how many pages turn and at what speed. This creates a fluid, dynamic navigation experience where users can quickly jump through pages by dragging faster or farther, or navigate page-by-page with slower, shorter drags.
Solution Approach 2:
The system performs preliminary action by preparing and pre-rendering page turn animations and effects before the user completes their gesture. When a user initiates a drag gesture, the system begins processing the page navigation sequence in advance, pre-loading and preparing the visual effects so that the page turning appears smooth and instantaneous rather than delayed, reducing perceived waiting time.
3Adaptability or versatility
If the mobile terminal provides basic touch input functionality, then the device maintains simplicity, but it cannot detect and respond to complex gesture combinations for enhanced document control
Solution Approach 1:
The patent applies universality by designing a gesture recognition system that handles multiple types of interactions through a unified framework. The same touch screen and gesture detection hardware that processes simple taps also detects complex drag gestures, pinch gestures, and swipe gestures for document navigation. This multi-functional approach allows the system to respond to various gesture types without requiring separate dedicated hardware for each input method.
Solution Approach 2:
The patent segments the gesture recognition process into distinct analytical components: detecting the initial touch point, tracking the drag trajectory, calculating drag distance and speed, determining gesture duration, and interpreting the combination of these parameters to trigger specific page navigation actions. This segmentation allows the system to process complex gestures by breaking them down into manageable detection and response stages.

AI summary
A mobile terminal and a method of controlling the operation of the mobile terminal are provided. The method includes displaying an electronic document screen showing one of a plurality of pages of an electronic document on a display module; if a first input that satisfies a predefined condition is detected from the electronic document screen, increasing a page quantity to be turned according to the duration of the first input; and if a second input is detected from the electronic document screen, jumping a number of pages corresponding to the increased page quantity and displaying a subsequent page on the electronic document screen. Therefore, it is possible to navigate to any desired page in an electronic document with convenience.
