Avatar Animation Synchronization Across Diverse Tracking Methods
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video distribution technologies do not effectively utilize tracking devices attached to the body of distributors, such as head-mounted displays and AR glasses, to generate and display animations synchronized with the motion of multiple distributors, leading to inefficiencies in video generation and display across different tracking methods.
Innovation Solution
A computer program and method that utilize multiple tracking devices to generate and display videos of avatars based on motion data from various tracking methods, allowing for synchronized animation of avatars across different terminal devices, including those using first and second tracking methods, and enabling display on a variety of devices like HMDs and smartphones.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple tracking devices with different tracking methods are used to generate motion data from multiple distributors, then the realism and interaction in virtual spaces are enhanced, but the complexity of video generation and synchronization increases
Solution Approach 1:
The patent introduces a server as an intermediary component that receives motion data from multiple terminal devices using different tracking methods, processes and synchronizes the data, and generates coordinated avatar animations. This mediator architecture allows the system to handle complexity centrally while maintaining simplicity at the client level, resolving the contradiction between enhanced realism and system complexity.
Solution Approach 2:
The server is designed with multi-functional capabilities to handle various tracking methods (first tracking method, second tracking method), process motion data from multiple distributors, generate animations for multiple avatars, and manage synchronization. This universal design allows the system to accommodate diverse tracking technologies without requiring separate processing systems for each method.
2Adaptability or versatility
If motion data from multiple distributors using different tracking methods is processed to generate synchronized avatar animations, then the video distribution experience is improved, but the processing time and computational resources increase
Solution Approach 1:
The system performs preliminary actions by pre-processing and normalizing motion data from different tracking methods as they are received, preparing the data in a standardized format before synchronization and animation generation. This preliminary preparation reduces the computational burden during the final rendering phase, thereby reducing overall video generation time while maintaining compatibility with various tracking methods.
3Adaptability or versatility
If terminal devices use different tracking methods (first tracking method and second tracking method), then the versatility of the system is improved, but the difficulty of synchronizing motion data increases
Solution Approach 1:
The server applies parameter changes by transforming motion data from different tracking methods into a unified parameter space. It normalizes timing, coordinate systems, and motion scales across different tracking methods, enabling synchronized avatar animations despite the diversity of input sources. This parameter standardization resolves the synchronization difficulty while preserving support for multiple tracking methods.
Data Source
AI summary
A first video is displayed that is generated based on motion of a user and is represented as viewed from a viewpoint of the user, the user being a user of the terminal device. In combination with the first video, an input object is displayed that functions as a user interface enabling input by the user. The input object that is displayed is caused to change according to the type of the first video that is displayed.
