Touch-Sensitive Display Page Turning Without Dedicated Hardware
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic book readers require dedicated hardware devices or GUI components for page-scrolling operations, which limits operability, especially on small screens and versatile operating systems.
Innovation Solution
An information processing apparatus with a display unit that detects user activations on a visually imperceptible portion of the screen, allowing page switching without dedicated hardware or GUI components, using multi-touch operations to simulate page-turning actions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If dedicated hardware devices (touch sensors, bend sensors) are used for page scrolling, then page scrolling operability is improved, but device complexity increases and hardware cost increases
Solution Approach 1:
The display screen is designed to serve multiple functions: it acts as both the content display area and the input detection area. The same display screen detects both visual content and touch inputs for page scrolling, eliminating the need for separate dedicated hardware sensors and achieving multi-functionality.
Solution Approach 2:
The invention merges the display function and input detection function into a single integrated system. The display screen and touch sensor layer are combined into one component structure, where the display screen serves as both the visual output interface and the touch input interface, reducing overall device complexity.
2Ease of operation
If GUI components (scroll bars) are displayed for page scrolling, then page scrolling functionality is added, but the display area for content is reduced
Solution Approach 1:
The invention extracts the scrolling control functionality from the visible display area and relocates it to an invisible or minimally visible region. By placing the detection area at the edge or corner of the screen where it is visually imperceptible, the main content display area remains fully intact while scrolling functionality is preserved.
Solution Approach 2:
The invention moves the scrolling control interface from the two-dimensional visible display plane to a different spatial dimension - the edge or corner region that is visually imperceptible. This allows users to access scrolling functionality without occupying valuable display real estate, effectively utilizing unused screen perimeter space.
3Adaptability or versatility
If GUI components are displayed on small screens, then page scrolling is enabled, but operability deteriorates due to limited space
Solution Approach 1:
The invention copies the physical book interaction model to the digital interface. By detecting touch gestures at the edge of the screen that simulate the physical action of turning a page, the system provides intuitive page scrolling operation that mirrors real-world book handling, making it naturally adaptable to small screen devices without requiring large GUI controls.
4Adaptability or versatility
If versatile operating systems are used, then system compatibility is improved, but dedicated hardware requirements increase
Solution Approach 1:
The display screen is designed to serve multiple functions across different operating systems and applications. The same touch-sensitive display infrastructure supports both content display and gesture recognition for page scrolling, providing universal functionality that works across versatile operating systems without requiring OS-specific hardware.

AI summary
An apparatus and method provide logic for processing information. In one implementation, an apparatus includes a display unit configured to display content to a user. The display unit includes a display surface, and the content is associated with at least a portion of a first page of an electronic document. A detection unit is configured to detect a first type of user activation associated with a first-type activation position on the display surface. A control unit is configured to determine whether the first-type activation position falls within a predetermined portion of the display screen, which is visually imperceptible to the user. The control unit is further configured to identify a first successive page of the electronic document based on at least the type of user activation, when the activation falls within the pre-determined portion.
