SYSTEM AND METHOD FOR MOTION CAPTURE - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240280687 titled 'SYSTEM AND METHOD FOR MOTION CAPTURE
- Simplified Explanation:**
Ultra-wideband (UWB) tags can be used in a high-resolution motion capture system without the typical cost and complexity of visually based systems. UWB tags are attached to the user's body parts to track motion, and their positions are determined using inter-tag ranging measurements.
- Key Features and Innovation:**
- Utilizes UWB tags for high-resolution motion capture - Tracks body motion by affixing tags to body parts - Determines absolute positions of tags using inter-tag ranging measurements - Reconstructs skeletal topology from a distance matrix based on UWB protocol signals
- Potential Applications:**
- Virtual reality and augmented reality systems - Biomechanics research and analysis - Sports performance tracking - Physical therapy and rehabilitation monitoring
- Problems Solved:**
- Cost and complexity of traditional motion capture systems - Limited mobility and range of motion tracking - Invasive attachment methods for tracking devices
- Benefits:**
- High-resolution motion capture without visual markers - Accurate tracking of body movements - Non-invasive attachment of UWB tags - Real-time monitoring and analysis of motion data
- Commercial Applications:**
Potential commercial uses include: - Entertainment industry for motion capture in movies and video games - Healthcare sector for rehabilitation and physical therapy applications - Sports industry for performance analysis and training programs
- Questions about UWB-based Motion Capture:**
1. How does UWB technology improve motion capture compared to traditional methods? 2. What are the advantages of using UWB tags for tracking body motion?
Original Abstract Submitted
ultra-wideband (uwb) tags can be used as part of a high-resolution motion capture system that may not require a cost or a complexity that is typically associated with visually based motion capture systems. the uwb based motion capture uses a bundle of uwb tags, which in a possible implementation, can be affixed to body parts of a user to sense motion of the body parts. the absolute positions of each uwb tag can then be determined by reconstructing a skeletal topology from a euclidean distance matrix based on inter-tag ranging measurements using handshake signals of a uwb protocol.
