Sightline-Adaptive Hologram Module Positioning for In-Air Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Hologram images in vehicles are position-dependent and sightline-dependent, leading to varying visibility and difficulty in accurate manipulation, especially when the angle between the user's sightline and the hologram is 90 degrees, limiting usability to specific users.
Innovation Solution
A hologram position control apparatus and method that adjusts the horizontal and vertical angles of a hologram display module based on the user's position and sightline, using processors to calculate correction angles and adjust the module's position dynamically to optimize visibility and facilitate manipulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the hologram module position is fixed, then the device complexity is reduced, but the hologram visibility varies according to user position and sightline
Solution Approach 1:
The patent applies the dynamics principle by making the hologram module position adjustable rather than fixed. The module can dynamically change its horizontal and vertical angles based on user position and sightline detection, resolving the contradiction between device simplicity and adaptability to different users.
Solution Approach 2:
The patent changes the operational parameters (horizontal angle and vertical angle) of the hologram module to optimize visibility for different users. By adjusting these parameters based on detected user position and sightline, the system maintains good visibility across various user positions without requiring complete system redesign.
2Adaptability or versatility
If the hologram module position is adjusted based on user position and sightline, then the hologram visibility is optimized for all users, but the device complexity increases
Solution Approach 1:
The patent implements feedback by detecting user position and sightline, then using this information to automatically adjust the hologram module position. This closed-loop control system optimizes visibility for each user while managing complexity through automated adjustment rather than manual configuration.
Solution Approach 2:
The system performs self-adjustment based on detected user characteristics. The hologram module automatically positions itself to provide optimal visibility without requiring manual intervention, reducing the operational complexity despite the increased adjustment capability.
3Illumination intensity
If the hologram is displayed at a fixed angle of 90 degrees to the sightline, then the visibility is best for a specific user, but the usability is limited to that specific user
Solution Approach 1:
The patent applies local quality by optimizing the hologram display angle specifically for each user's sightline rather than using a universal fixed angle. The horizontal and vertical angle adjustments are tailored to each user's position, providing 90-degree optimal viewing conditions locally for each user rather than globally for all users.
