Transparent Display Mode Switching via Eye Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices with transparent screens, such as spectacle-type devices, have non-adjustable transparency, leading to inconvenient frequent takeoff-and-wear and poor user experience due to tedious operation mode switching and reduced display effects.
Innovation Solution
An operation mode switching method that detects a user's eyeball movement to adjust the transparency of the screen, allowing seamless switching between modes without additional user actions, using a detecting member to identify trigger events and judge predefined conditions for switching between high and low light-transmittance modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the transparency of the lens-screen is kept low to improve display visibility, then the display effect is improved, but the user cannot see the real world clearly and must frequently take off the device
Solution Approach 1:
The patent applies dynamics by making the transparency of the lens-screen adjustable rather than fixed. The system dynamically changes the transparency parameter based on user needs, allowing the display to switch between high transparency (for seeing the real world) and low transparency (for improved display visibility). This resolves the contradiction by enabling the transparency to adapt to different usage scenarios.
Solution Approach 2:
The patent changes the transparency parameter of the lens-screen to resolve the contradiction. By adjusting the transparency parameter between different levels, the system can optimize for either display visibility or real-world viewing as needed, eliminating the need for frequent device removal while maintaining both functions.
2Ease of operation
If the transparency of the lens-screen is increased to allow users to see the real world, then the ease of operation is improved, but the display effect deteriorates
Solution Approach 1:
The system dynamically adjusts the transparency parameter based on the selected operation mode. When real-world viewing is needed, transparency is increased; when display viewing is needed, transparency is decreased. This dynamic adjustment resolves the contradiction by ensuring the transparency level matches the current usage requirement.
Solution Approach 2:
The transparency parameter is changed according to the operation mode to resolve the contradiction between ease of operation and display effect. The system selectively adjusts this parameter to optimize for the current task, whether it's viewing the real world or viewing the display content.
3Device complexity
If traditional menu settings are used to adjust transparency and luminance parameters, then the device complexity is reduced, but the ease of operation deteriorates due to tedious gestures
Solution Approach 1:
The system performs self-service by automatically adjusting transparency and luminance parameters based on the detected operation mode without requiring manual user input. The device monitors its own usage context and autonomously optimizes display parameters, eliminating the need for users to navigate through settings menus and perform tedious adjustment gestures.
Solution Approach 2:
The system uses feedback from operation mode detection to automatically adjust display parameters. By monitoring the current operation mode (e.g., transparent mode, display mode, mixed mode), the system provides real-time feedback-based adjustments to transparency and luminance, improving ease of operation while maintaining simple device structure.
4Device complexity
If the device maintains fixed transparency to simplify the device structure, then the device complexity is reduced, but the adaptability deteriorates
Solution Approach 1:
The patent applies dynamics by transforming the fixed transparency structure into a dynamic, adjustable one. The transparency parameter can now change based on the operation mode, enabling the device to adapt to different usage scenarios while maintaining relatively simple overall structure through automated control.
Solution Approach 2:
The transparency parameter is made changeable according to different operation modes, resolving the contradiction between device simplicity and adaptability. The system achieves versatility through parameter adjustment rather than through complex structural changes, maintaining ease of manufacture while gaining adaptability.
