Motion capture, or “mocap” for short and also known as performance capture, is a production tool and technique used to track and record the movement of people and convert it into digital data. This data can be applied to digital characters or objects to create lifelike or realistic animation. 

Mocap systems are wearable technology that is most commonly used to track body, face, or hand movements. They can vary between multiple camera tracking set-ups, such as OptiTrack and Vicon, to a single wearable technology with individual sensors, such as Rokoko and Xsens.
