External Display for Head-Mounted VR Sharing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Virtual reality head-mounted displays isolate users from those around them, leading to social stigma when used in public settings, as only the wearer experiences the virtual environment.
Innovation Solution
A multiple screen head-mounted display system that includes a first transceiver to obtain a first perspective for a user-facing display and a second transceiver to provide a second perspective for an external facing display, allowing observers to share the virtual reality experience by rendering a second scene on an external display that can be wirelessly controlled by observers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a VR headset displays graphics exclusively for the wearer, then the immersive visual experience is improved, but user isolation and social stigma increase
Solution Approach 1:
The display system is segmented into multiple independent display surfaces: a primary display for the wearer and secondary displays for observers. This segmentation allows the virtual environment to be distributed across multiple viewing zones, enabling simultaneous immersive experience for the wearer and shared experience for observers, thereby reducing user isolation while maintaining visual quality.
Solution Approach 2:
Secondary displays positioned between the wearer and observers act as intermediaries, projecting portions of the virtual environment outward. This intermediary mechanism allows observers to view the virtual content without interfering with the wearer's immersive experience, facilitating social interaction while preserving the primary visual experience quality.
2Adaptability or versatility
If an external facing display is added to share the virtual environment, then social acceptance is improved, but device complexity increases
Solution Approach 1:
The external facing display serves multiple functions: it projects the virtual environment for observer viewing, provides contextual information about the virtual scene, and can display interactive controls. This multi-functionality allows a single additional component to address social acceptance needs while managing overall system complexity through functional consolidation.
Solution Approach 2:
The external facing display creates simplified copies or representations of the virtual environment rather than transmitting the full complex scene. By projecting selected portions, simplified views, or key elements of the virtual scene, the system shares the experience with observers while avoiding the complexity of transmitting and rendering complete high-fidelity virtual environments to multiple displays.

AI summary
Devices and methods disclosed herein may include a system for a multiple screen head-mounted display. The system includes a first transceiver to obtain a first perspective of a virtual environment. The first perspective may be used to render a first scene on a user facing display of a head-mounted display. The system further includes a calculator to transform the virtual environment from the first perspective to a second perspective. A second transceiver may provide the second perspective for use to render a second scene on an external facing display of the head-mounted display.
