Server-Side Web Content Adaptation for Regional Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for presenting applications to devices lack a mechanism to dynamically change display content for different regions without requiring changes to the computer program on the device side, limiting flexibility and regional adaptation.
Innovation Solution
A system comprising a server that transmits Web content data including display information and application commands to devices, allowing devices to display and execute applications based on user interactions, without needing program changes on the device side, enabling dynamic content adaptation for different regions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If display content of a page for introducing an application is changed on the server side, then the content can be updated flexibly, but the computer program on the device side must be changed in accordance with the change
Solution Approach 1:
The patent introduces a server as an intermediary between the user and the application distribution system. The server stores multiple versions of display content (HTML pages) for different regions and devices, and dynamically selects and transmits the appropriate version based on device information. This mediator approach allows the device program to remain simple while the server handles the complexity of managing region-specific display content variations.
2Adaptability or versatility
If a mechanism is established to provide pages with different display content for each region, then regional adaptation is improved, but the system complexity increases
Solution Approach 1:
The patent adds a new dimension to the system by introducing region-specific HTML page versions stored on the server. Instead of modifying the device program to handle regional variations, the solution creates multiple dimensional versions of the display content (different HTML files for different regions) and selects the appropriate dimension based on device information. This approach maintains simple device programs while achieving regional adaptation through server-side dimensionality.

AI summary
A system includes: a server and at least one device. The server includes a control unit configured to transmit Web content data including display information indicating at least one application that is able to be used by a device and at least one application command to cause the device to perform processing related to the at least one application. The device includes: a Web browser including: a display control unit configured to perform control for displaying a screen based on the Web content data on a display unit; and an execution unit configured to request execution of an application command included in the Web content data in accordance with an operation performed by a user via the screen; and a processing execution unit configured to, based on a request from the Web browser, perform processing related to an application corresponding to the request.
