Two-Dimensional Touch Control for Dynamic Scrolling Speed and Display Mode
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image browsing and searching methods require separate operations to adjust scrolling speed and display mode, which can be cumbersome and lead to missed images due to fixed image sizes and speeds.
Innovation Solution
An information display device that allows users to control scrolling speed and display mode through a two-dimensional plane defined by axes, where motion components along these axes determine the speed and mode, enabling simultaneous adjustment of both parameters in a single operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If images are displayed with a fixed size during scrolling, then the display is simple to implement, but the user may miss some display images and requires separate operations to adjust scrolling speed and display size
Solution Approach 1:
The patent combines the control of scrolling speed and display mode into a single unified operation. The reception unit receives one instruction that simultaneously specifies both the scrolling speed and display mode based on the movement amount and direction on the touch panel, eliminating the need for separate operations to adjust each parameter independently.
Solution Approach 2:
The patent introduces a two-dimensional plane for control where the movement amount in the scrolling direction controls speed and the movement amount in the perpendicular direction controls display mode. This dimensional mapping allows users to adjust multiple parameters through a single intuitive gesture on the touch panel surface.
2Productivity
If the scrolling speed is increased to browse more images quickly, then the browsing efficiency improves, but the user cannot take time to check the images thoroughly
Solution Approach 1:
The patent makes the scrolling speed dynamic and adjustable during the browsing process. Users can change the scrolling speed by performing additional touch operations, allowing the system to adapt to the user's current needs - faster scrolling for efficient browsing when time is limited, and slower scrolling when thorough examination is desired.
3Quantity of substance
If the display size of images is reduced to show more images at once, then more images can be viewed simultaneously, but the image quality and detail become harder to discern
Solution Approach 1:
The patent implements dynamic display mode adjustment where the display size can be changed during scrolling based on user input. Users can switch between different display modes (e.g., thumbnail view showing many small images, and detailed view showing fewer larger images) by performing touch operations, allowing flexible adaptation between viewing quantity and image quality requirements.

AI summary
The present invention aims to provide an information display device for easily changing a scrolling speed and a display mode. The information display device receives an instruction for displaying a plurality of contents, via a move operation on a two-dimensional plane defined by first and second axes; determines a moving speed for moving the contents, based on a motion component of the move operation along the first axis, and determines a display mode for displaying the contents, based on a motion component of the move operation along the second axis; and displays the contents in the display mode on a screen, by scrolling through the contents at the moving speed.
