Display Controller Setting Reversion for Multi-User Consistency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of display apparatuses, such as projectors, often encounter settings changed by previous users, leading to undesirable viewing experiences due to the need for statistical values to be created for each setting, resulting in potential misuse of settings by multiple users.
Innovation Solution
A display apparatus with multiple input sections and a controller that allows users to switch between setting information, automatically reverting to initial settings when a new input section is selected, preventing the propagation of changed settings from one user to another, and includes features to alert users of inappropriate setting changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If setting values are changed by users in accordance with visual/audio environment and user preference, then user preference satisfaction is improved, but setting values changed by previous users cause problems for next users
Solution Approach 1:
The patent segments setting values into two categories: automatically updated settings (such as contrast, brightness, color temperature) and manually updated settings (such as input section selection, image size). This segmentation allows automatic updates based on statistical analysis while preserving user-specific manual choices, resolving the contradiction between adapting to user preference and maintaining setting consistency.
Solution Approach 2:
The system changes parameters dynamically based on statistical analysis of user behavior. When a setting value exceeds a predetermined number of changes within a predetermined time period, the system automatically updates that setting to the most frequently used value, thereby adapting to user preferences while preventing excessive manual modifications from affecting other users.
2Adaptability or versatility
If statistical values are created for each setting value on a user basis to automatically change setting values, then user-specific settings are improved, but the complexity of creating and managing statistical values increases
Solution Approach 1:
The patent creates a single statistical value that applies universally to multiple setting values rather than creating separate statistical values for each setting. This universal statistical value tracks the frequency of changes across different settings, simplifying the management complexity while still enabling user-specific adaptation for automatically updated settings.
Solution Approach 2:
The system automatically monitors and analyzes setting value changes without requiring manual user input or complex configuration. The statistical value is generated and updated automatically based on usage patterns, and the system self-adjusts by applying the most frequently used setting values, eliminating the need for manual statistical value management.
3Adaptability or versatility
If setting values are automatically updated based on usage frequency, then user preference adaptation is improved, but the ability to maintain appropriate reference values is worsened
Solution Approach 1:
The patent implements dynamic setting management where setting values can automatically update based on statistical analysis of usage patterns. The system monitors change frequency and automatically adjusts settings when thresholds are exceeded, allowing the system to adapt dynamically to user preferences while maintaining stability through predetermined update criteria.
Solution Approach 2:
The system continuously monitors setting value changes and uses this feedback to update statistical values. When the statistical value indicates that a setting has been changed excessively, the system feeds this information back to automatically update the setting to the most frequently used value, creating a closed-loop system that adapts to user preferences while maintaining appropriate reference values.

AI summary
A display apparatus includes a display section that displays an image and a controller that controls the display apparatus based on setting information to cause the display section to display the image and changes the setting information from first setting information to second setting information in accordance with a first instruction. In a state in which the controller has changed the setting information from the first setting information to the second setting information and causes the display section to display a first image based on first image information from the first input section, and when the controller receives a second instruction to cause the display section to display a second image based on second image information from the second input section, the controller changes the setting information from the second setting information to the first setting information and causes the display section to display the second image.
