Adaptive Display Adjustment Using User Vision and Distance Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing digital devices lack dynamic and user-specific adjustment of display settings to accommodate individual user preferences and visual capabilities, such as distance from the screen and prescription lenses, leading to suboptimal viewing experiences.
Innovation Solution
A system that adjusts display features based on user and usage parameters, including distance estimation, visual capabilities, and lens detection, using sensors and machine executable code to modify display characteristics like zoom, focus, and brightness to mimic the view through specific prescription lenses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If display settings are fixed for all users, then device complexity is reduced, but user experience and accessibility are worsened
Solution Approach 1:
The system automatically detects user parameters (eye distance, lens type) and adjusts display settings without requiring manual user input. The device serves itself by using sensors to gather data and algorithms to determine optimal display characteristics, eliminating the need for users to manually configure settings while maintaining high adaptability.
Solution Approach 2:
The system dynamically changes display parameters such as zoom level, focus distance, and brightness based on detected user characteristics. By modifying these parameters in real-time according to user-specific data, the system achieves high adaptability while keeping the underlying hardware structure relatively simple.
2Ease of operation
If manual display setting adjustment is provided, then user control is improved, but ease of operation is worsened
Solution Approach 1:
The system performs preliminary detection of user parameters before display adjustment is needed. By pre-detecting eye distance, lens type, and other visual characteristics, the system automatically configures optimal display settings in advance, eliminating the need for users to spend time manually adjusting settings while maintaining full user control when needed.
3Measurement precision
If generic display settings are used, then device complexity is reduced, but measurement precision of user-specific needs is worsened
Solution Approach 1:
The system uses a multi-functional approach where a single sensor suite (camera, depth sensor) serves multiple detection purposes including eye distance measurement, lens type identification, and visual capability assessment. This universal detection system achieves high measurement precision for user-specific needs while avoiding the complexity of separate specialized sensors for each parameter.
