This cheap solution looks pretty impressive.
Tweets from the team's account share details on their solution called MocapForAll which lets you use cameras from smartphones and webcams for full-body motion tracking. The tech is said to be using deep learning algorithms to track motion.
The new solution requires using at least two cameras but you can also plug in additional ones for better results. A recent Tweet says the app will be available for around $100, with a time-limited free trial.
