Vertical Movement Sensing for Electronic Document Page Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable terminals with small screens face challenges in displaying electronic documents with multiple pages efficiently, as they struggle to handle large amounts of information and navigating through pages is cumbersome due to limited screen size and the need for page turning functions.
Innovation Solution
A method and system that utilize a display capable of sensing vertical movement, allowing pages to be turned by detecting movement or pressure, enabling the display of corresponding pages based on user interaction, and allowing for transparent display of additional pages for comparison.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If a small screen is used in portable terminals, then portability is improved, but the ability to display electronic documents with large amounts of information or multiple pages deteriorates
Solution Approach 1:
The patent introduces the vertical dimension (Z-axis) for page navigation, allowing users to move pages by approaching or retracting their hand from the screen. This transforms the traditional 2D horizontal scrolling into a 3D vertical interaction, enabling multiple pages to be accessed on a small screen without requiring larger display area.
2Device complexity
If traditional page turning functions are used on small screens, then device simplicity is maintained, but operability deteriorates due to cumbersome navigation
Solution Approach 1:
The patent replaces traditional mechanical or software-based page turning mechanisms (swiping, clicking, keyboard navigation) with a proximity-based sensing system. The display detects the presence and movement of the user's hand in the vertical direction, automatically triggering page transitions without requiring physical contact or complex gesture recognition.
3Loss of information
If multiple pages are displayed simultaneously, then information accessibility is improved, but screen real estate is insufficient
Solution Approach 1:
The patent prepares multiple pages in advance by stacking them vertically in the detection range above the screen. As the user's hand moves through different vertical positions, the system pre-loads and positions corresponding pages for immediate display, enabling smooth transitions between multiple pages without requiring additional screen space.
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
Improves operability by allowing easy navigation and comparison of document pages, enhancing the browsing experience on portable devices by leveraging movement or pressure sensors to manage page display and transparency.
Implementation Method 1
a display configured to sense movement of a movable object in a vertical direction relative to a screen
Data Source
AI summary
An electronic document includes a set of pages. A display is used that is configured to sense movement of a movable object in a vertical direction relative to a screen. In response to sensing movement using the display, a page corresponding to the electronic document is displayed on the screen in accordance with the sensed movement.
