Motion Capture has become more commonly used across many industries to provide accurate and organic movement of humans. One of the driving forces for mocap progress comes from the video game industry. Ever since the Sega Model 2 arcade game - Virtual Fighter 2 in 1994 - motion capture has rapidly increased throughout the years. Motion capture technology is able to provide easier and smoother workflows for both indie game developers and larger games companies.
When it comes to mocap, there are multiple solutions available but it really comes down to what the use-case is and budget. Systems vary in accuracy and price but all require a certain amount of clean up to be done in post. Starting with optical systems, OptiTrack and VICON are the leaders in the industry, providing solutions in animation, movement sciences, virtual reality and robotics. They are most commonly used in AAA games as they provide the highest fidelity tracking available as well as handle batch recordings in a more flexible way.
Inertial suits on the other hand such as Xsens and Perception Neuron, are mostly used in indie games companies as they are more affordable and do not require a large capture volume. They do tend to require more post clean up as the data is easily interfered but with an ideal setup, game developers can achieve smooth and lifelike animations for a fraction of an optical system’s cost.
