Autostereoscopic Display Windows for Shared 3D Immersion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional autostereoscopic displays provide limited immersive experiences for viewers, especially when multiple persons are involved, as they offer a restricted view of the virtual world and lack interaction capabilities.
Innovation Solution
A system comprising multiple autostereoscopic display devices that work together to create a single virtual 3D-environment, allowing movable virtual windows that adapt to viewer positions, using eye trackers and virtual stereo cameras to ensure each viewer experiences the environment from their perspective.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single autostereoscopic display device is used, then the device complexity is low, but the immersion and view of the virtual world are limited
Solution Approach 1:
Multiple autostereoscopic display devices are merged into a coupled system that presents a unified virtual 3D-environment. The devices work together as an integrated whole, sharing coordinate systems and synchronizing content delivery, thereby enhancing immersion without requiring each individual device to be overly complex
Solution Approach 2:
The coupled display system provides multiple functions: it enables both individual immersive experiences through personal virtual windows and collaborative experiences through shared virtual space. The system adapts to different usage scenarios (single user, multiple users, mobile, stationary) while maintaining a consistent technical framework
2Area of stationary object
If multiple autostereoscopic display devices are coupled to expand the virtual world view, then the immersion and view are enhanced, but the device complexity increases
Solution Approach 1:
The virtual 3D-environment is segmented into multiple virtual windows, with each autostereoscopic display device presenting a portion of the overall environment. This segmentation allows the system to manage complexity by dividing the rendering and presentation tasks across multiple devices while maintaining a cohesive virtual world
Solution Approach 2:
The system transitions from a single-device two-dimensional display limitation to a multi-device three-dimensional virtual space. By adding the spatial dimension of multiple devices arranged in space, the system creates a volumetric virtual environment that expands the viewable area without proportionally increasing complexity
3Adaptability or versatility
If conventional autostereoscopic displays are used, then the setup is simple, but multiple viewers cannot experience the virtual world together
Solution Approach 1:
A synchronization mechanism acts as an intermediary between multiple display devices and viewers. This mediator coordinates the presentation of stereoscopic images across devices, ensures proper timing, and manages the complex interactions required for multi-viewer experiences without requiring each device to independently handle all complexity
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enhances immersion for individual viewers and enables multiple persons to interact within the same virtual 3D-environment by providing an enlarged view and synchronized perspectives across devices.
Implementation Method 1
a screen that comprises a lenticular lens or parallax barrier. This ensures that the autostereoscopic display can simultaneously direct a left eye image exclusively to a left eye of the viewer and a right eye image exclusively to a right eye of the viewer

AI summary
The invention relates to an autostereoscopic display system configured to display a single virtual 3D-environment on at least two autostereoscopic display devices to one or more viewers, wherein each of the autostereoscopic display devices defines a virtual window allowing a viewer to experience a part of the virtual 3D-environment. At least one virtual window is a movable virtual window that is movable within the virtual 3D-environment by moving, in the real world, the autostereoscopic display device that defines the movable virtual window. In this way, the system of the invention allows a viewer to experience the part of the virtual 3D-environment through a movable virtual window from a perspective that constantly corresponds to the actual position of the eyes of the viewer relative to the virtual 3D-environment.
