VR Video Hotspot Region Tracking and Prompting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In virtual reality panoramic video systems, users often miss highlight content due to random angle switching, leading to a poor user experience as they lack guidance on viewing the entire panoramic image.
Innovation Solution
A VR video processing method and apparatus that uses a cloud device to track user angle changes, create region popularity tables to identify hotspot regions, and provide prompts to guide users towards viewing highlight content, ensuring they do not miss interesting parts of the video.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users autonomously switch angle of view in VR panoramic video, then users can selectively view scenarios of interest, but users may miss highlight content and lack overall understanding of panoramic image
Solution Approach 1:
The system collects viewing data from multiple users, analyzes popularity of different regions, and provides feedback by displaying prompt information that guides users to highlight content. This feedback loop enables users to discover important content they might have missed while maintaining their freedom to explore.
Solution Approach 2:
The system introduces an intermediary mechanism (prompt information display) that mediates between user autonomy and content discovery. The prompt information acts as a guide without forcing users to view specific content, resolving the conflict between freedom of choice and information completeness.
2Loss of information
If the system provides guidance on highlight content, then users can view important parts of panoramic video, but system complexity increases due to tracking and analysis requirements
Solution Approach 1:
The cloud device performs multiple functions: it tracks user viewing data, analyzes popularity statistics, generates prompt information, and transmits guidance data. By consolidating these functions in a centralized cloud system rather than requiring complex local processing in each user device, the solution reduces overall system complexity while maintaining comprehensive guidance capabilities.
3Measurement precision
If real-time tracking of user angle changes is implemented, then highlight content can be identified accurately, but processing time and computational resources increase
Solution Approach 1:
The system continuously collects and pre-processes viewing data in the background, maintaining ready-to-use popularity statistics and prompt information. This preliminary action ensures that when users need guidance, the system can quickly retrieve and display relevant information without requiring time-consuming real-time analysis, thus reducing perceived processing time while maintaining tracking accuracy.

AI summary
Embodiments of the present invention disclose a VR video processing method and a related apparatus. According to the method, a video processing device can divide received video image into a plurality of regions, establish a region popularity table of the video image and update the region popularity table by tracking an angle of view of a user when a video is playing, to collect information about a hotspot region in a panoramic video and send a hotspot region prompt to the user. According to the method, moving of the angle of view of the user can be effectively guided, and the user will not miss highlight content in the panoramic video, thereby improving user experience.
