Transparent AR Display Positioning for Unobstructed User Vision
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional transparent display devices obstruct the user's vision when displaying auxiliary information, as they do not effectively integrate virtual and real-world views without blocking the object behind the display.
Innovation Solution
A method and device that utilize a transparent display device with camera units to determine the user's viewpoint and object coordinates, allowing for precise positioning of auxiliary information on the display without obstructing the view, and adjust display brightness based on environmental conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If auxiliary information is displayed on a transparent display device, then information provision is improved, but user vision of the object is blocked
Solution Approach 1:
The patent applies dimensionality change by transitioning from traditional 2D display coordinates to 3D spatial coordinates. The system determines the three-dimensional coordinate location of the viewpoint and object, then maps the auxiliary information to a displaying position on the transparent display device based on these 3D coordinates. This spatial mapping allows the auxiliary information to be positioned in a way that minimizes obstruction of the user's view of the actual object while ensuring the information is still visible and accessible.
2Device complexity
If the display position of auxiliary information is fixed, then device complexity is reduced, but adaptability to different viewing conditions is worsened
Solution Approach 1:
The patent implements dynamics by making the display position of auxiliary information adaptive rather than fixed. The system dynamically determines the displaying position based on the real-time three-dimensional coordinate location of the viewpoint and the object. As the user's viewpoint or the object's position changes, the auxiliary information automatically adjusts its position on the transparent display device to maintain optimal visibility and minimize obstruction, thereby adapting to different viewing conditions without requiring complex manual configuration.
3Loss of information
If the transparent display device is placed in front of the user's view, then information display capability is improved, but transparency and view clarity are worsened
Solution Approach 1:
The patent applies local quality by selectively positioning auxiliary information in specific regions on the transparent display device rather than uniformly displaying it across the entire surface. The system determines the three-dimensional coordinate location of both the viewpoint and the object, then calculates an appropriate displaying position that places the auxiliary information in less critical viewing areas. This localized positioning strategy ensures that the auxiliary information is displayed in regions that minimize interference with the user's view of the actual object, thereby maintaining view clarity while still providing necessary information.

AI summary
An augmented reality display method based on a transparent display device and a device are disclosed. The transparent display device is disposed between a user and an object. The method includes: determining a first three-dimensional coordinate location of a user viewpoint related to the transparent display device; determining a second three-dimensional coordinate location of the object related to the transparent display device; determining a position of the object on a viewing region of the transparent display device according to the first and the second three-dimensional coordinate locations; determining a displaying position of the auxiliary information of the object according to the position of the object; and controlling the device to display the auxiliary information of the object at the displaying position. Accordingly, the technology problem that a vision of the user is blocked when displaying the auxiliary information of the object is avoided.
