E-book Page Turning via Touch Gestures and 3-Axis Sensor
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing e-book interfaces in portable terminals lack ergonomic design for natural page-turning, making it difficult for users to navigate through content similar to turning pages in a physical book.
Innovation Solution
A method and apparatus for turning pages of an e-book in a portable terminal using touch inputs and 3-axis sensors to mimic the experience of turning physical pages, allowing users to input commands through touch down, drag, and touch up gestures on a touch-sensitive screen, and utilizing sensors to detect inclination for page navigation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If key manipulation interface is used for page turning, then basic direction control function is achieved, but user convenience and natural interaction are poor
Solution Approach 1:
The patent replaces the mechanical key pressing system with a touch-sensitive screen that detects finger contact and movement. The touch screen senses the user's finger position and dragging motion, translating these physical gestures into digital page-turning commands, thereby eliminating the need for physical keys and providing a more natural interaction experience.
Solution Approach 2:
The patent creates a visual copy of a physical book page on the display screen, complete with page curvature effects and shadow rendering. This visual replication allows users to interact with the digital content as if it were a physical book, maintaining the familiar page-turning gesture while achieving digital functionality.
2Ease of operation
If traditional key-based page navigation is implemented, then page turning function is achieved, but natural page-turning experience similar to physical books is lost
Solution Approach 1:
The patent replaces the mechanical key pressing system with a touch-sensitive screen that detects finger contact and movement. The touch screen senses the user's finger position and dragging motion, translating these physical gestures into digital page-turning commands, thereby eliminating the need for physical keys and providing a more natural interaction experience.
Solution Approach 2:
The patent introduces an intermediary layer between the user and the digital content - a touch-sensitive interface that captures natural finger gestures and translates them into meaningful navigation commands. This intermediary layer processes the raw touch input, determines the user's intent, and executes the appropriate page-turning action, bridging the gap between physical gesture and digital response.
3Ease of operation
If touch-sensitive screen with gesture recognition is used, then natural page-turning interaction is achieved, but device complexity increases
Solution Approach 1:
The patent makes the touch-sensitive screen serve multiple functions: it displays the e-book content, detects user touch gestures, and provides visual feedback during page turning. By consolidating these functions into a single component, the patent avoids adding separate sensors and control mechanisms, thereby reducing overall device complexity while achieving natural interaction.
Solution Approach 2:
The patent merges the display function and the input sensing function into a single touch-sensitive screen assembly. The screen both shows the book content and detects finger contact, position, and movement, eliminating the need for separate physical keys or additional sensors, thus achieving intuitive control without proportionally increasing complexity.

AI summary
An apparatus and method for turning pages of an electronic-book (e-book) in a portable terminal having an e-book function are provided. The method includes executing the e-book function, displaying a right lateral side of the e-book and driving a 3-axis sensor when a touch down is input in a pre-set right User Interface (UI) active area of the e-book, determining whether an inclination value greater than or equal to a threshold is detected in a left direction, and upon detection of the inclination value greater than or equal to the threshold in the left direction, displaying a next page to a screen on a single-page basis at a speed in proportion to the inclination value detected in the process of detecting the inclination greater than or equal to the threshold in the left direction.
