Facial motion capture is more challenging than body animation due to the higher resolution required to detect and track subtle expressions made from small movements of the eyes, eye-brows, lips, etc. These movements are often less than a few millimeters, requiring even greater resolution and fidelity and different filtering techniques than usually used in full body capture. The additional constraints of the face also allow more opportunities for using models and rules.

Expression Grabber is STT’s package for facial movement capture. It is a real-time, optical capture system especially designed for today’s facial animation requirements in videogames, movie production, TV commercials, etc. It shares the same user interface as Motion Grabber, which facilitates the learning process while preserving the potential of Motion Grabber.

The full package includes the cameras and software, combining high-performance cameras with easy-to-use software that optimizes the use of the cameras and the available space in the studio.
