The Ariel Performance Analysis System (APAS) is a video-based 3D motion analysis system. APAS can capture video from multiple cameras simultaneously and perform a biomechanical analysis automatically.

The Ariel Performance Analysis System measures, analyzes, and presents movement characteristics. The system provides a means to quantify motion utilizing input information from any or all of the following media: visual (video), electromyography (EMG), and force platforms.

Professionals whose work involves the measurement, assessment, or improvement of human performance have a computerized, fully-integrated toolkit for biomechanical measurement and analysis. The system models the human body as a mechanical system of moving segments upon which muscular, gravitational, inertial, and reaction forces are applied. It is noninvasive and does not require wires or sensors. Markers are optional.

Areas of successful application for APAS include human performance, injury and rehabilitation assessment, quantification of loss for compensation claims, equipment and product testing and development, determination of potential or actual risks for products and activities in liability litigation, as well as applied research in the areas of orthopedic medicine, therapeutics, and physical training.

The APAS integrates state-of-the-art computer and video processing hardware with software modules that perform data collection, analysis, and presentation. The system is user-friendly, requiring no special knowledge of computers or data processing. At every point during the analysis, the user is presented a menu of functions and options supported with help screens that can be immediately accessed.
