An Introduction to AI Motion Capture

September 5, 2024

AI motion capture is not just the future of fitness technology; it could have a wide-reaching impact on the world of healthcare, well-being, and sports. Gone are the days of multiple cameras, expensive studios, and professional motion-capture suits. We can now undertake accurate motion analysis with nothing more than the phone in your pocket. 

Whether used as part of a fitness tracking app, undertaking health assessments or providing insights on form and injury prevention, it’s changing the game. This post explores everything there is to know about AI motion capture, how it works, how you can use it, and the benefits it can bring to your customers.

What is AI Motion Capture?

AI motion capture takes information from a video and uses artificial intelligence to capture and analyze the person’s movements. It has many uses in healthcare, animation, VR and other applications, and we’re only at the beginning of understanding what this exciting new technology can do.

In years gone by, motion capture needed specialized equipment such as a large studio, multiple cameras, bodysuits with markers, and very powerful computers to pull it all together. It’s an expensive and time-consuming way to go about body tracking, and that’s before any of the analysis takes place.

However, with an existing video, a phone, or another type of camera, such as a webcam, AI motion tracking can capture precise data very quickly.

How Does AI Motion Capture Work?

AI motion tracking starts with a subject who performs a range of movements in front of the camera. These could be anything from exercises to walking, dancing to various postures.

An algorithm like our groundbreaking Motion Operation System (M-OS) analyzes each frame individually. It identifies key points on the subject’s body, such as joints and limbs, and converts them into precise human motion data in real-time. This can then be analyzed against the rest of our dataset to provide instant, accurate insights to the user.

How Can AI Motion Capture Be Used?

There are endless potential possibilities for implementing AI motion tracking and analysis into apps, businesses or other technology. Currently, the fitness, healthcare, wellbeing and insurance industries are finding that it can transform their businesses. Whether it’s increased efficiency, adding value for customers or increasing the efficacy of a product, it’s groundbreaking.

AI Motion Analysis in Fitness Apps

Fitness app developers have found they can offer their users highly personalized experiences through the use of AI, improving customer satisfaction and retention. By using customer data and combining it with their long-term health and fitness goals, AI can provide truly unique workout plans that achieve results. By using AI motion capture, the app can provide form analysis which improves results and reduces the chances of injury.

AI Motion Capture in Healthcare & Rehabilitation

Healthcare providers and professionals can utilize AI to improve treatment rates for patients, transform health assessments, increase efficiency, and provide early indications of upcoming health concerns.

For example, a simple health assessment may no longer need a visit to a health professional if the patient can take a simple video and AI motion capture technology can do the rest. By analyzing patterns of movement and identifying risk factors, preventative care plans can be implemented and regularly assessed. 

If a patient is recovering from an injury, they might not need an in-person physiotherapist if AI can provide instant feedback on the form and efficacy of their rehab exercises. Not only does the patient recover faster, they can reduce the chance of re-injury. 

In fact, the MRC Laboratory of Medical Sciences, Imperial College London, and Great Ormond Street Hospital have developed a way to monitor the progression of movement disorders using AI motion tracking.

AI Motion Capture for Insurance

Health insurance companies can incentivize and empower their customers to live healthy lifestyles through AI motion analysis and tracking. For example, recognizing that they could reduce costs by assisting their (largely elderly) customers to undertake daily exercises, Japanese health insurance company SOMPO used AI motion capture in their app.

Research showed that their customers had little idea of how to exercise. Therefore, SOMPO provided personalized body assessments via the app before devising individual digital health and wellness programs, helping users remain committed to their long-term fitness goals.

AI motion capture and analysis will continue to become more prevalent across multiple industries and sectors. Innovative companies that adopt and implement AI motion tracking may see their investment rewarded with improved customer acquisition and retention, increased efficiencies and a better product.
