AR Content Positioning for Shared VR Spectator Interaction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The limited social interactions and disparity in user experiences between primary and secondary users in virtual reality content viewing, particularly when only one user wears a head-mountable display unit, result in unsatisfactory experiences for secondary users.
Innovation Solution
Generating augmented reality (AR) content elements that are synchronized with primary content, allowing secondary users to view relevant information and interact with the content through AR elements displayed in their environment, enhancing engagement and immersion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single HMD is provided for primary user viewing, then the primary user experience is immersive and high-quality, but secondary users experience a significant disparity and dissatisfaction
Solution Approach 1:
The system segments the viewing experience by providing different content representations to different users: the primary user receives the original immersive VR content through HMD, while secondary users receive processed 2D video representations on conventional displays. This segmentation allows each user type to receive optimized content for their specific viewing context, resolving the contradiction between maintaining high primary user experience quality and providing acceptable secondary user experience.
2Adaptability or versatility
If multi-user VR arrangements are provided to support multiple HMDs, then more users can experience immersive content, but device complexity and processing requirements increase significantly
Solution Approach 1:
The system applies local quality by providing full immersive VR rendering only to the primary user's HMD, while secondary users receive processed 2D video representations on conventional displays. This approach maintains high-quality immersive rendering for the single HMD user without requiring the system to handle multiple complex VR rendering pipelines, thereby reducing overall device complexity while still supporting multiple users.
3Adaptability or versatility
If a spectator screen displaying the HMD user's view is provided, then secondary users can view content, but interactivity and engagement are reduced
Solution Approach 1:
The system transitions the secondary user experience from a constrained 2D spectator screen view to a more immersive spatial experience by rendering 3D computer-generated content that can be displayed on conventional displays with enhanced depth perception. This dimensional enhancement allows secondary users to engage with the content more actively, improving interactivity and engagement while maintaining the ability to view the content.

AI summary
A system for generating secondary content for display, the secondary content being augmented reality content corresponding to primary content for display by a first display device, the system including a primary content characterisation unit operable to characterise the primary content, a secondary content generation unit operable to generate, in dependence upon the characterisation of the primary content, secondary content including one or more secondary content elements associated with the primary content, and a content positioning unit operable to position one or more secondary content elements with respect to one or more elements in a real environment, where the user of a second display device is able to view the secondary content elements overlaid upon a view of the real environment at the respective specified positions.
