Modern tracking technology for full body tracking, also referred to as motion capturing, can be used as an alternative or a complementary method to video recordings (see also Chapter 72. a on documenting with data gloves for a discussion). It offers a high precision of position and orientation information regarding specific points of reference, which can be chosen by the experimenter. Motion tracking can be used to collect movement trajectories, posture data, speed profiles and other performance indices. Disadvantages are: the relatively obtrusive technology that has to be applied to the body of the tracked person, such as reflective markers used by optical tracking systems; data which describes the postures and movements of a stick-like figure rather than of a body with certain masses (for this reason, motion capturing should generally be combined with video recordings); and last but not least the costs of the installation. The following text provides a short introduction to the state of the art of tracking technology that is available for use in laboratories. While some companies do offer high-quality motion capturing services for the film and gaming industries, making use of their services is probably beyond the scope of any modest research project. The following presentation is therefore focused on technology that can currently be found in research laboratories.
