Body Motion Part Segmentation for Accurate Input Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies struggle to appropriately specify parts related to a user's body motion, leading to potential misinterpretation of intended motions and insufficient virtual character movements.
Innovation Solution
An information processing device that acquires outline information of a user's body motion and specifies a main part and related parts for correction processing based on this information, using sensors like image sensors or LiDAR to distinguish intended and unintended movements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If motion information of body parts is used without distinction of each part, then the system can capture all body movements, but the accuracy of identifying intended motions deteriorates
Solution Approach 1:
The patent segments body motion into main parts and related parts. The specification unit divides the motion information into two categories: main part motion information (which reflects the user's intended motion) and related part motion information (which reflects incidental movements). This segmentation allows the system to focus on relevant motions while filtering out noise, thereby improving identification accuracy without requiring overly complex analysis of every body part movement.
2Productivity
If all body part movements are recognized as equipment operation, then the system responds to all motions, but erroneous activations increase
Solution Approach 1:
The patent extracts only the necessary motion information for equipment operation. The specification unit identifies and extracts main part motion information that corresponds to the user's intended operation, while excluding related part motion information that represents incidental or unintended movements. This extraction process ensures that equipment responds only to relevant motions, preventing erroneous activations while maintaining responsive operation.
3Measurement precision
If motion information is used without correction, then the processing is simple, but the accuracy of user input recognition deteriorates
Solution Approach 1:
The patent performs preliminary correction of motion information before using it for equipment control. The correction unit pre-processes the motion information by adjusting or filtering related part motion data based on the identified main part motions. This preliminary action ensures that the motion information fed into the equipment control system is already refined and accurate, improving user input recognition without requiring complex real-time processing during operation.

AI summary
An information processing device according to the present disclosure includes: an acquisition unit that acquires outline information indicating an outline of a user who makes a body motion; and a specification unit that specifies, among body parts, a main part corresponding to the body motion and a related part, which is to be a target of correction processing of motion information corresponding to the body motion, on the basis of the outline information acquired by the acquisition unit.
