Multimedia Interacting System Using Video Segments for Virtual Space
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In virtual space systems, the lack of 3D models prevents accurate determination of user interactions and interactive ranges, making it difficult to assess whether users can interact with each other based on video content alone.
Innovation Solution
A multimedia interacting system and method that uses a server to communicate with display devices, receiving video-playing times, identifying unsheltered areas, and transmitting interactive data to determine if users can see each other's avatars or sounds by correlating video times with corresponding tour videos and calculating virtual distances based on field of views.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If video editing techniques are applied to build a virtual space system without 3D models, then the system can be built quickly and easily, but it cannot accurately determine user interaction ranges or obstacles between users
Solution Approach 1:
The virtual space is segmented into multiple video clips, each representing a specific location or viewpoint. By dividing the continuous space into discrete video segments, the system achieves ease of construction through video editing while enabling precise interaction determination by checking relationships between specific video segments.
Solution Approach 2:
The patent creates a virtual copy of physical space using video recordings instead of 3D models. Multiple video clips capture different locations and perspectives, forming a comprehensive virtual representation that enables interaction analysis without requiring complex 3D reconstruction.
2Measurement precision
If 3D models are built to accurately determine user interactions and obstacles, then measurement precision improves, but device complexity and manufacturing difficulty increase
Solution Approach 1:
Instead of creating permanent, complex 3D models, the system uses disposable video clips that can be easily stored, managed, and processed. These video segments serve as temporary representations of space that are sufficient for interaction determination without the overhead of complex 3D model structures.
Solution Approach 2:
The patent replaces the mechanical complexity of 3D model construction and processing with a simpler video-based system. By substituting geometric computations with video playback and comparison, the system achieves accurate interaction determination with reduced computational complexity.
3Measurement precision
If the system processes all video data to determine interactive ranges, then measurement precision improves, but data processing time and bandwidth consumption increase
Solution Approach 1:
The system pre-processes video data during the video clipping stage, organizing spatial relationships and interaction potentials in advance. By preparing video segments with metadata about their spatial context beforehand, the system avoids intensive real-time processing when determining user interactions.
Solution Approach 2:
Instead of processing all video data continuously, the system processes only the specific video clips relevant to current user positions and interaction queries. By selectively processing partial data based on user context, the system maintains precision while minimizing processing time and bandwidth usage.

AI summary
The present disclosure provides a multimedia interacting system. The multimedia interacting system comprises a first display device, a second display device, and a server. The server communicatively connects with the first display device and the second display device. The server is configured to receive a first playback time that the first display device plays a first tour video; obtain an unsheltered area associated with the first tour video based on the first playback time; obtain a second tour video corresponding to the unsheltered area; and transmit an interacting data to the first display device and the second display device if the second display device plays the second tour video.
