Transparent Holographic Display for Multi-User Perspective Rendering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mixed reality technologies fail to present different virtual scenes to users at different locations, resulting in unrealistic virtual scene presentations.
Innovation Solution
An image projection method and apparatus using a transparent holographic display screen with multiple display surfaces and projection light sources, coupled with eye-tracking and input operation sensing, to determine and display movement trajectories and appearance states of virtual interactive objects differently for users on each surface, simulating realistic interactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single virtual scene is displayed for all users regardless of their location, then the display system is simple to operate, but the virtual scene appears less realistic for users at different locations
Solution Approach 1:
The patent applies local quality by rendering different appearance state features for virtual interactive objects based on the specific eye positions of users at different locations. Each user receives a customized virtual scene configuration that matches their viewing perspective, making the virtual scene appear more realistic for each individual user while maintaining the same underlying system architecture.
2Reliability
If different virtual scenes are displayed to users at different locations, then the virtual scene appears more realistic for each user, but the system complexity increases
Solution Approach 1:
The patent segments the display system into independent rendering paths for different users. By determining and displaying different appearance state features for virtual interactive objects based on user eye positions, the system can independently customize each user's virtual scene without requiring complete system redesign, thus managing complexity while improving realism.
3Ease of operation
If the virtual interactive object displays the same appearance state for all users, then the system is easy to control, but the user experience is less immersive and realistic
Solution Approach 1:
The patent implements dynamics by making the appearance state features of virtual interactive objects variable rather than fixed. The system dynamically adjusts these features based on real-time determination of user eye positions, allowing the virtual objects to adapt their appearance to match each user's perspective and enhance immersion while maintaining straightforward control mechanisms.

AI summary
An image display method includes: obtaining an input operation by a first user on a virtual interactive object displayed on a first display surface of a transparent holographic display screen; determining, in conjunction with the input operation, a movement trajectory of the virtual interactive object, a first appearance state feature of the virtual interactive object relative to an eye position of the first user, and a second appearance state feature of the virtual interactive object relative to an eye position of a second user, after a current moment; displaying the virtual interactive object having the movement trajectory and the first appearance state feature on the first display surface of the transparent holographic display screen; and displaying the virtual interactive object having the movement trajectory and the second appearance state feature on a second display surface of the transparent holographic display screen.
