Motion Data Tagging and Section Replacement for Reuse
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies face challenges in reutilizing previously generated motion data, such as replacing user movements with reference motion data effectively.
Innovation Solution
An information processing apparatus and method that acquires motion data, imparts meta-information to associate with basic movements, and replaces designated sections of motion data with reference motion data using a sensor system and server-based similarity evaluation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If motion data is generated and stored for reutilization, then motion data availability increases, but motion data reutilization capability deteriorates
Solution Approach 1:
The motion data is segmented into multiple sections based on meta-information such as movement type, body part, and time period. This segmentation enables selective replacement of specific sections while preserving others, making the large volume of motion data reusable in different contexts. The imparting unit adds meta-information tags to each section, allowing the replacing unit to efficiently locate and substitute only the required portions.
Solution Approach 2:
Meta-information acts as an intermediary between the stored motion data and the replacement process. The meta-information (including movement type, body part, time period, and section identifiers) enables the system to match and replace appropriate motion sections without directly processing the entire motion data set, thus facilitating reutilization while maintaining data integrity.
2Speed
If motion data replacement is performed without section designation, then replacement speed increases, but replacement precision deteriorates
Solution Approach 1:
The imparting unit performs preliminary action by adding meta-information to the motion data before the replacement process. This pre-tagging of sections with movement type, body part, and time period information enables the replacing unit to quickly locate and precisely replace only the designated sections without manual search, achieving both high speed and high precision replacement.
3Stability of the object's composition
If detailed meta-information is added to motion data, then motion data organization improves, but data processing complexity increases
Solution Approach 1:
The meta-information structure is designed to be universal and multi-functional, serving multiple purposes simultaneously: section identification, movement type classification, body part specification, and time period marking. This unified approach improves motion data organization while avoiding the need for separate processing systems for each type of information, thus limiting the increase in processing complexity.

AI summary
To reutilize motion data.An information processing apparatus, including: an acquiring unit configured to acquire a motion data group indicating time-series data of motion of a user; an imparting unit configured to impart meta-information related to a basic movement in association with motion data with respect to the motion data group acquired by the acquiring unit; and a replacing unit configured to replace the motion data associated with the meta-information corresponding to a designated section indicating a section designated by the user among the motion data group with reference motion data to be a reference.
