VR Viewport Segmentation for Nausea Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional techniques for collaborative review and feedback in virtual reality (VR) video are inadequate, as they limit user interaction outside the VR view, cause nausea in shared viewing, and are inefficient for sharing and commenting within content editing applications.
Innovation Solution
The system generates a viewport that allows users to determine the source user's view without nausea, supports asynchronous output, and enables efficient distribution and annotation of VR video within a content editing application, using orientation tracking sensors and collaboration data to synchronize views and annotations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple VR devices share a single view of VR video controlled by one device, then users can view the same content, but this causes nausea to VR devices that do not control the view
Solution Approach 1:
The patent divides the VR video display into multiple independent viewports, each controlled by a different user's device. This segmentation allows each user to have their own navigation control while still sharing the same physical display space, eliminating the nausea caused by watching another user's controlled view while maintaining collaborative viewing capability.
Solution Approach 2:
The patent transitions from a single shared 3D VR view to multiple overlapping 3D VR views displayed simultaneously. By adding the dimension of multiple independent viewpoint layers, the system allows each user to navigate independently in their own viewport while others can observe, preventing nausea while enabling collaboration.
2Ease of operation
If VR video navigation is controlled by head movement in a source device, then the source user can interact naturally with the video, but other users experience nausea because the output does not follow their head movement
Solution Approach 1:
The patent segments the navigation control authority by creating separate viewports for each user. Each viewport is controlled independently by the respective user's head movements, allowing natural interaction for each user while others observe without experiencing nausea from mismatched motion cues.
Solution Approach 2:
The patent introduces viewports as intermediary layers between the source VR video and each reviewing user's display. These viewports act as independent mediation channels, each with its own navigation control, allowing the source user to interact naturally while reviewing users observe without nausea.
3Reliability
If conventional techniques are used to share VR video through remote databases or local storage, then video sharing is possible, but it requires users to navigate away from the content editing interface which is frustrating and inefficient
Solution Approach 1:
The patent merges the video sharing functionality directly into the content editing application interface. Multiple users can view and annotate VR video content without leaving the editing environment, combining collaboration and editing functions in one unified interface, thereby improving productivity while maintaining reliable sharing capability.
Solution Approach 2:
The patent creates a multi-functional system where the content editing application simultaneously provides video editing, sharing, collaborative viewing, and annotation capabilities. This universal interface eliminates the need to switch between applications, improving collaboration efficiency while maintaining robust video sharing functionality.
4Adaptability or versatility
If VR video is viewed in isolated views on separate devices, then each user has their own perspective, but users cannot easily share their views with each other for collaborative review
Solution Approach 1:
The patent merges multiple isolated VR video views into a single shared display space where each user's viewport is visible to others. This allows users to maintain their individual viewing perspectives while simultaneously enabling easy sharing and collaborative review, as all users can see each other's viewports and provide feedback in real-time.
Solution Approach 2:
The patent introduces viewports as intermediary elements that bridge isolated user views with collaborative review needs. Each viewport acts as a mediator that preserves the individual user's perspective while making it visible and accessible to other users for feedback and discussion.

AI summary
Techniques and systems to support collaborative interaction as part of virtual reality video are described. In one example, a viewport is generated such that a reviewing user of a reviewing user device may view VR video viewed by a source user of a source user device. The viewport, for instance, may be configured as a border at least partially surrounding a portion of the VR video output by the reviewing VR device. In another instance, the viewport is configured to support output of thumbnails within an output of VR video by the reviewing VR device. Techniques and systems are also described to support communication of annotations between the source and reviewing VR devices. Techniques and systems are also described to support efficient distribution of VR video within a context of a content editing application.
