Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display systems fail to automatically adjust resolution based on user distance and preference, leading to suboptimal viewing comfort and convenience, as they require burdensome user interactions to set display properties.
Innovation Solution
A display system comprising a display device, image sensor, face recognition unit, distance detection unit, and controller that captures user images, recognizes faces, determines distance, and adjusts resolution based on user preference data to optimize visual comfort and convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If display resolution is fixed for all users, then device complexity is reduced, but visual comfort deteriorates due to varying viewing distances and user preferences
Solution Approach 1:
The display resolution is made dynamic rather than fixed. The system automatically adjusts resolution based on real-time detection of user distance and recognition of user identity, allowing the display parameters to adapt to varying viewing conditions and user preferences without requiring manual intervention.
Solution Approach 2:
The system incorporates feedback mechanisms through distance detection units and face recognition units that continuously monitor viewing conditions. Based on this feedback, the controller automatically adjusts display resolution to optimize visual comfort for each user, creating a closed-loop control system that responds to actual usage conditions.
2Ease of operation
If display resolution is manually adjusted for each user, then visual comfort is improved, but ease of operation deteriorates due to burdensome user interactions
Solution Approach 1:
The display system performs self-adjustment of resolution parameters without requiring user intervention. Through automatic face recognition and distance detection, the system identifies the user and viewing conditions, then autonomously configures optimal display settings, eliminating the need for manual adjustment while maintaining high visual comfort.
Solution Approach 2:
The system pre-stores display preference data for multiple users during initial setup. When a user approaches, the system retrieves pre-configured preferences and automatically applies appropriate resolution settings, avoiding the need for real-time manual adjustment and reducing time loss.
3Manufacturing precision
If display resolution is increased for better visibility, then visual comfort improves, but device complexity increases due to additional sensors and control systems
Solution Approach 1:
The image sensor serves multiple functions: it captures images for face recognition, determines user distance through image analysis, and provides input for display parameter adjustment. This multi-functionality reduces the need for separate dedicated sensors, thereby limiting the increase in device complexity while still enabling automatic resolution adjustment.
Solution Approach 2:
The system combines face recognition and distance detection functions into a unified control mechanism. Both functions utilize the same image sensor and controller, merging multiple subsystems into an integrated solution that adjusts display resolution based on the combination of user identity and viewing distance, rather than requiring separate independent systems.
Data Source
AI summary
A display system for improving visual comfort and a method of adaptively adjusting resolution of a display device are provided. The display system includes a display device, a memory, an image sensor, a face recognition unit, a distance detection unit, and a controller. The memory stores face representation data and user preference data. The image sensor captures an image and converts it into an electrical signal. The face recognition unit analyzes that electrical signal to recognize a face image and compares the recognized face image with the face representation data to generate a first signal. The distance detection unit analyzes the electrical signal to determine a distance between the display device and the user to generate a second signal. The controller then generates a parameter based on the first signal and the second signal and adjusts a display resolution of the display device based on the parameter.
