Wearable Motion Tracking for Full-Body Virtual Mapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current technologies for interacting with virtual environments are limited by the inability to accurately and precisely map a user's full body motions into digital environments, typically only allowing control through hand and head movements.
Innovation Solution
A wearable frame with an array of sensing devices and a control unit that tracks the user's body movements in real-time, transmitting signals to accurately determine the position and orientation of body sections, allowing for precise mapping and manipulation of a virtual avatar.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If hand-held devices are used to control virtual environments, then device complexity is reduced, but measurement precision of body motions deteriorates
Solution Approach 1:
The body is segmented into multiple trackable sections (head, hands, feet, torso) with individual markers or sensors placed on each segment. This allows independent tracking of each body part's position and orientation, achieving comprehensive and precise full-body motion capture without requiring a single complex device.
2Device complexity
If only head and hands are tracked, then device complexity is minimized, but adaptability of body control deteriorates
Solution Approach 1:
The motion mapping system is designed to track multiple body sections simultaneously (head, hands, feet, torso, arms, legs), making it universally applicable to various virtual environment interactions. This multi-functional capability allows the same system to support diverse control scenarios including walking, gesturing, posing, and full-body animations, greatly enhancing adaptability.

AI summary
Devices and methods of real-time mapping of a user's body. The devices and methods involve a user wearing one or more wearable article(s) of a frame such that sensing devices of the wearable article(s) are located on one or more section(s) of the user's body. Signals are transmitted with the sensing devices and received with at least one control unit. Movement of the section(s) of the user's body are determined based on the signal, and motion data are provided to a virtual environment based on the movement of the section(s) of the user's body.
