Dynamic Display Region Management for Multi-User Conference Data Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information processing apparatuses for conferences do not allow logged-in users to access data from users who have logged out, limiting data accessibility and collaboration during and after a conference.
Innovation Solution
An information processing apparatus with a display unit and a display control unit that displays personal and common images in specific regions, allowing logged-in users to access data from users who have logged out by moving images from personal to common display regions based on user operations, and managing access authorities and data deletion based on user presence and effective periods.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If personal display regions are used for each user's data, then data security and user-specific access control are improved, but data accessibility for logged-in users to view logged-out users' data deteriorates
Solution Approach 1:
The display is divided into multiple personal display regions, with each region assigned to a specific user. This segmentation allows data to be organized by user while maintaining security boundaries, as each personal region is initially accessible only to its assigned user.
Solution Approach 2:
Personal display regions can be merged into a common display region when users log out. This merging mechanism allows data from logged-out users to become accessible to remaining logged-in users, resolving the contradiction between security and accessibility by dynamically adjusting region assignments based on user presence.
2Ease of operation
If personal display regions are assigned to each user, then user-specific data management is improved, but device complexity increases
Solution Approach 1:
The display regions are designed to be dynamic rather than static. Personal display regions automatically transition to common display regions based on user login/logout status, eliminating the need for manual reconfiguration and reducing operational complexity despite the multi-user environment.
Solution Approach 2:
The common display region serves multiple functions: it displays data from logged-out users and acts as a shared space for all users. This multi-functionality reduces the need for separate mechanisms to handle different display scenarios, simplifying overall system operation.
3Adaptability or versatility
If data is retained after user logout, then data accessibility is improved, but loss of information control worsens
Solution Approach 1:
The system automatically transfers data from personal display regions to common display regions upon user logout, before any potential loss of control. This preliminary action ensures data remains accessible while maintaining structured control over its display location and access permissions.
Solution Approach 2:
The system provides feedback mechanisms including display notifications when data is moved to common regions, and automatic deletion after a predetermined period. This feedback loop maintains information control by allowing users to track and manage their data's lifecycle from personal to common display regions.

AI summary
An information processing apparatus to which a plurality of users can log in includes: a display unit configured to display an image; and a display controller configured to display personal region images corresponding to the respective users in a plurality of personal display regions at different positions in a display face of the display unit, display common images in the same common display region among the users in the display face of the display unit, and display images of data acquired on the authority to access of a corresponding user in the personal display regions to be movable, respectively, wherein when any of the users logs out, the display controller finishes displaying the image arranged in the personal display region among the data acquired on the authority to access of the user who logs out, and continues to display the image arranged in the common display region.
