Automated motion capture - such as the Motion Analysis Corporation system used at ASMI - often relies on tracking reflective markers in artificial lighting. In other words, sunlight from windows can mess everything up.
At ASMI we wanted to study long toss, which obviously can not be done realistically in our lab. So, after some pilot work and consulting with other biomechanists, we took our indoor lab outdoors. We collected data at night, when there was no sunlight but plenty of stadium lighting. The technology worked really well.
Here is a video of the data collection:
I'm sorry about the ads on the right. I have no control over that. The video might look better (without the ads) if you hit the "full screen" button on the youtube video.
