Using Motion Capture Technology to Help the Physically Impaired.
SESAY: Hello everyone. The force is definitely with the new Star Wars movie. It became the fastest movie of all time to hit the $1 billion mark at the box office this weekend. It took just 12 days to pass in Jurassic World which hit the mark in 13 days earlier this year. And also to the top spot for Christmas day earning at $153.5 million and it's already the fifth biggest film in U.S. history. Well, the movie hasn't even officially opened in China yet, but some lucky fans got a sneak preview Sunday. The cast walked the red carpet in Shanghai and the film Chinese premiere greeting fan and filing autographs.</s>UNIDENTIFIED MALE, THROUGH AN INTERPRETER: I can't wait to see how wonderful it would be. Because I know it won't be a bad film. I'm expecting it to be amazing. I hope it will bring back the same feeling I had when I watched Star Wars as a child.</s>SESAY: Well most Chinese fans still have to wait a little bit longer for the movie. It officially opens in China on January 9th. Well so much with all the magic in Hollywood from raptors in Jurassic World to aliens Star Wars spanks the motion capture technology. And now it's gaining traction elsewhere to CNN's Anna Stewart with many young girls suffering from cerebral palsy, who hopes that technology can help her walk.</s>UNIDENTIFIED FEMALE: Can you lift his leg up in the air for me? Like that.</s>ANNA STEWART, CNN CORRESPONDENT: Rachelle is 8 years old. She suffers from cerebral palsy.</s>UNIDENTIFIED FEMALE: And again big lift.</s>STEWART: A disorder which affects muscle control making it increasingly hard to walk.</s>UNIDENTIFIED FEMALE: Very good.</s>ALISON DEWDNEY, MOTHER: We are here to assess her walking session and to see if her current splints are doing the job that they should be doing.</s>UNIDENTIFIED FEMALE: Are you ready, steady, and go.</s>STEWART: These small sticky balls will help measure exactly how Rachelle is walking using cutting-edge motion capture technology.</s>DEWDNEY: They come out on the computer screen. They showed the pattern of where her bones for and she's walking.</s>STEWART: Motion capture actually started here in life sciences. But it wasn't long before their movie is record on. Driving the development, making it cheaper and more accessible to healthcare and many other industries.</s>UNIDENTIFIED MALE: Does it look like just apes to you?</s>STEWART: They all look very real and that's because behind every monster there's a real life actor. Today that's me. Nick, I'm all fitted up. I'm ready to go. I don't look how it goes that went for my first Hollywood performance. What's going on?</s>NICK BOLTON, CEO OXFORD METRICS MOTION GROUP: Well I'm sorry about that but first of all but -- so what you got on a series of reflected markers, you have all around your body from and back, heads and feet. And we're filming those movements of those markers from multiple angles. As you can see on the screen here, here's your character (ph) when you move your left arm. It moves, maybe your right arm that moves and so forth.</s>STEWART: This is an exactly blockbuster stuff. The next step is to match the motion capture to a graphic character. Be at beast or maybe a warrior princess.</s>BOLTON: Well motion captures only in people's living realms. They connect sensor from marked off from the x box (ph). Right, that's the motion capture system. We see motion capture automatically, you know, exploring into market base. But actually almost creepy into our lives, you know, in much more soulful (ph) way</s>UNIDENTIFIED FEMALE: Steady and go.</s>STEWART: And as it finds more uses, the technology will get better and cheaper perfect for life science virtual will begin. So hopefully more kids like Rachelle will reap the benefit. Anna Stewart CNN, Oxford.</s>SESAY: Let's hope so. You're watching CNN NEWSROOM live from Los Angeles. I am Isha Sesay.
