Real-Time Motion Capture in Your Pocket
MobilePoser, a real-time system designed for full-body motion capture using inertial measurement units (IMUs) present in consumer devices like phones, watches, and earbuds. The aim of MobilePoser is to perform accurate full-body pose and motion estimation using the minimal hardware already available in everyday technology.
Here’s a breakdown:
- Trend and Challenge: Motion capture technology has evolved from requiring specialized equipment to using more accessible IMUs in common devices. However, as the technology relies on lower-quality sensors, challenges like performance degradation, inconsistency over time, and inaccurate translation due to sensor noise arise.
- MobilePoser: To address these issues, MobilePoser integrates deep learning and physics-based optimization. It processes IMU data from any available subset of devices, estimating the user's full-body pose and motion in real time.
- Two Main Modules:
- Physics Optimizer: Refines the results to ensure the estimated body motion follows physical constraints, improving the overall accuracy.
- Applications: MobilePoser can be applied to various fields such as health monitoring, gaming, and indoor navigation by leveraging the ubiquitous use of commodity devices.
In summary, MobilePoser is a cutting-edge solution for motion capture that doesn't require specialized equipment, making it more accessible for real-world applications while maintaining accuracy through advanced AI and physics-based techniques.
