Object Display Apparatus Operation Control for Multi-User Interference
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display systems for multiple users face challenges in controlling operations to prevent interference between individual operators' actions, particularly in personal work modes where operators focus on separate objects, leading to potential conflicts and limitations in operation due to overlapping objects.
Innovation Solution
An object display apparatus that determines operation modes (group or personal) based on user interactions, assigns objects to operators, and controls operations to prevent interference by limiting actions that could affect other operators' objects, without dividing the working area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If operators work individually on separate objects without area division, then operability and flexibility are improved, but operations may interfere with each other causing display state conflicts
Solution Approach 1:
The operation control section monitors operations in real-time and provides feedback by detecting conflicts between operations on different objects. When a conflict is detected (e.g., one operator's operation would affect another operator's object display state), the system responds by controlling or limiting the conflicting operation, thereby maintaining display state stability while allowing flexible individual operations.
2Reliability
If working area is divided for respective operators, then operation interference is prevented, but operation contents are limited and flexibility is reduced
Solution Approach 1:
The system virtually segments the working space by assigning specific objects to specific operators without physically dividing the display area. This allows each operator to have dedicated control over assigned objects while maintaining access to the entire display space, preventing interference through logical separation rather than spatial partitioning.
Solution Approach 2:
The operation control section dynamically adjusts operation permissions based on real-time detection of operation conflicts. Rather than static area division, the system flexibly controls operations by detecting when one operator's actions would affect another's objects and selectively limiting those operations, thereby maintaining both independence and flexibility.
3Productivity
If operators focus on separate objects individually, then personal work efficiency is improved, but operations on one object can affect display state of another object
Solution Approach 1:
The operation control section acts as an intermediary between operators' operations and the display state. It monitors operations performed on assigned objects and controls them to prevent harmful effects on other operators' objects, thereby allowing efficient individual work while eliminating operation interference through intermediate control.

AI summary
An object display apparatus includes: a display section; an operating section configured to allow one or more operators to operate objects displayed on the display section; and a work-type determining section configured to set an operation mode to a group mode or a personal mode. The object display apparatus further includes an object assigning section configured to assign a corresponding object to each of the operators, on the operation mode being set to the personal mode; and an operation control section configured to, on the operation mode being set to the personal mode, determine whether an operation performed on one of the objects by one of the operators can affect a display state of another object assigned to another operator, and control the operation with putting a limit on the operation, in response to determining that the operation can affect the display state of the another object.
