Adaptive Display Brightness Control for User Distraction Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display devices can distract users by maintaining constant brightness, which may hinder work or other activities, as they do not adapt to the user's status or environment.
Innovation Solution
A control device with a processor that detects the user's status and adjusts the display screen's brightness or reduces brightness changes over time to minimize distraction, by lowering luminance or switching between moving and still images based on proximity and user activity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the display device maintains constant high brightness, then the information display function is ensured, but the user's concentration and work efficiency are hindered due to distraction
Solution Approach 1:
The display device dynamically adjusts brightness based on detected user status (proximity, attention state, work intensity) rather than maintaining a fixed brightness level. The processor monitors user status in real-time and modifies display parameters accordingly, transforming the static display into an adaptive system that responds to user needs.
Solution Approach 2:
The system changes display parameters (brightness, contrast, content type) based on detected user status. When the user is in a high-concentration state or close proximity, the processor reduces brightness or displays still images instead of moving images, thereby adjusting the display output to match the user's current state and reduce distraction.
2Object-affected harmful factors
If the display device lowers brightness to reduce distraction, then user concentration is improved, but the information visibility and display effectiveness are reduced
Solution Approach 1:
The system applies different display qualities to different situations rather than uniformly reducing brightness. When the user is far away or not engaged in concentration-intensive work, the display maintains normal brightness and moving images. Only when specific user status conditions are met (close proximity, high concentration state) does the system adjust brightness or content type, applying quality changes locally to specific contexts.
Solution Approach 2:
The display device dynamically switches between different display modes (normal mode, reduced brightness mode, still image mode) based on real-time user status detection. The processor continuously monitors user position and attention state, adjusting display parameters dynamically to maintain information visibility while reducing distraction only when necessary.
3Adaptability or versatility
If the display device frequently changes brightness to adapt to user status, then user comfort is improved, but the system complexity and processing requirements increase
Solution Approach 1:
The display device performs self-adjustment based on automatic detection of user status. The processor monitors user proximity and attention state through sensors and autonomously decides when to adjust brightness or content type without requiring manual user input or complex external control systems, thereby reducing overall system complexity while maintaining adaptability.
Solution Approach 2:
The system implements a feedback loop where the processor continuously monitors user status (through proximity sensors, attention detection) and adjusts display parameters accordingly. This closed-loop control allows the display to adapt to user needs automatically, with the feedback mechanism being simple enough to avoid excessive system complexity while achieving effective adaptation.
4Use of energy by moving object
If the display device maintains high brightness, then energy consumption is high, but reducing brightness may affect display quality and user experience
Solution Approach 1:
The display device uses periodic action by switching between moving images and still images based on user status. When the user is in a state where distraction should be reduced, the system displays still images which consume less energy than continuous moving images, while maintaining adequate display quality for the context. This periodic switching optimizes energy consumption without permanently degrading display quality.
Solution Approach 2:
The system changes display parameters (brightness level, image type) based on user status and contextual factors. By adjusting these parameters dynamically, the display maintains high quality when needed (normal brightness and moving images when user is engaged or far away) while reducing energy consumption when appropriate (lower brightness or still images when user is close and concentrating), achieving a balance between quality and energy efficiency.

AI summary
A control device includes a processor configured to grasp a status of a user around a display device and lower brightness of a display screen of the display device or reduce a change in brightness of the display screen per unit time in a case where the grasped status of the user is a specific status.
