VR Motion Data Recording and Reproduction System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing VR content recording and reproduction technologies face challenges when the reproduction device lacks full support for the functions of the recording device, leading to incomplete reproduction of VR content due to different providers and updates, resulting in user inability to view VR content.
Innovation Solution
A system where the recording device stores data related to object motion and available functions, allowing the reproduction device to specify and reproduce only the functions it supports, enabling partial reproduction of VR content based on its capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the recording device stores complete data related to all functions for moving the object, then the reproduction device can reproduce the motion accurately, but the data storage requirement and system complexity increase
Solution Approach 1:
The patent segments the function data into a hierarchical structure with function classes and individual functions. This allows the reproduction device to selectively process only the necessary function data rather than handling all possible functions, reducing processing complexity while maintaining reproduction accuracy for supported functions.
Solution Approach 2:
The patent extracts and stores metadata about available functions separately from the motion data itself. This extraction allows the reproduction device to quickly identify which functions are supported and retrieve only those specific function data, avoiding the need to process complete function sets and reducing overall system complexity.
2Adaptability or versatility
If the reproduction device supports all functions of the recording device, then complete VR content can be reproduced, but the device requirements and cost increase
Solution Approach 1:
The patent implements a dynamic function selection mechanism where the reproduction device adapts to the recording device's capabilities by specifying which functions it supports. This allows the system to flexibly match functions between devices without requiring the reproduction device to permanently support all possible functions, reducing device complexity while maintaining adaptability.
Solution Approach 2:
The patent changes the parameter of function support from a static all-or-nothing approach to a selective parameter-based approach. The reproduction device can specify subsets of supported functions through parameters, allowing it to operate with limited capabilities while still reproducing VR content to the extent of its supported functions.
3Ease of operation
If the reproduction device specifies only supported functions, then it can reproduce VR content with limited functionality, but complete reproduction may not be achieved
Solution Approach 1:
The patent applies partial action by allowing the reproduction device to reproduce only the portion of VR content that corresponds to its supported functions. Rather than requiring complete function support for full reproduction, the system accepts partial reproduction of supported functions, making reproduction feasible on diverse devices while being transparent about the functionality loss.
Data Source
AI summary
In a recording device configured to record a motion of an object in a virtual space, a data structure of data related to the motion of the object recorded by the recording device is used for a process of reproducing the motion of the object in the reproduction device. The recording device includes a controller and a storage. The controller causes the storage to store, in association with the object, the data related to the motion of the object and data related to available functions for a process of moving the object. The data related to the available functions for the process of moving the object is stored in the storage so that the reproduction device is able to specify a function class that is reproducible by the reproduction device.
