Document Display Mode Switching for Time-Limited Browsing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Documents with set browsing time limits may be deleted without the user being aware that the limit is approaching, leading to potential loss of important information.
Innovation Solution
An information processing apparatus that switches the display mode of documents with approaching browsing time limits, alerting users by changing the display mode, such as making the document icon semi-transparent or animated, to prompt browsing before the limit expires.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If documents with browsing time limits are displayed in normal mode without alerts, then the display interface remains simple and clean, but users may not notice approaching time limits and documents may be deleted accidentally
Solution Approach 1:
The patent applies color changes to document icons based on the remaining browsing time. When the browsing time limit approaches expiration, the icon color changes to warn users, providing a visual alert without requiring complex additional interface elements or changing the fundamental display structure.
Solution Approach 2:
The system periodically checks the browsing time limits of displayed documents and dynamically adjusts the icon appearance accordingly. This periodic monitoring and updating mechanism ensures users are alerted to approaching time limits without requiring continuous complex processing or permanent interface changes.
2Loss of information
If the system monitors and alerts users about approaching browsing time limits, then document deletion is prevented, but the display processing complexity increases
Solution Approach 1:
The patent uses color changes as a simple visual indicator to alert users to approaching browsing time limits. This approach prevents information loss by making expiration warnings visible without requiring complex alert mechanisms, additional interface elements, or sophisticated processing logic.
Solution Approach 2:
The display system automatically monitors browsing time limits and adjusts icon appearance without requiring user intervention or complex external monitoring. The system serves itself by autonomously detecting time limit status and applying appropriate visual warnings, reducing the need for additional processing complexity.
3Difficulty of detecting and measuring
If document icons are displayed with time limit warnings, then user awareness of browsing deadlines improves, but the visual clarity and simplicity of the interface decreases
Solution Approach 1:
The patent employs color changes on document icons to indicate approaching browsing time limits. This method improves time limit detection by providing clear visual cues while maintaining interface simplicity, as color is an inherent property of the existing icon elements rather than requiring additional interface components or complex visual overlays.
Solution Approach 2:
The warning mechanism applies local quality changes only to specific document icons that have approaching time limits, rather than altering the entire interface. This allows users to detect time limits easily through localized visual changes on relevant icons while the rest of the interface remains simple and unchanged.

AI summary
An information processing apparatus includes a display unit that display's a document in a first display mode by switching a document display mode from a second display mode to the first display mode in a case where the document displayed is a distributed document or a document having been distributed, where the document has not been browsed, and where a browsing time limit set for the document expires within a first predetermined period.
