The APAS TutorialsbyGideon Ariel, Ph.D."If at first you don't succeed, try reading the instructions"
The following Tutorials represent all the APAS modules. Text, Images and Video files are utilized to give the reader the best knowledge and experience in using the APAS system. Each month an additional tutorial will be published on our web site at: / , starting with the RealCap Module and sequentially progress to the Capture, Trimming, Digitizing, Transformation, Filtering, Display, Analog, EMG, Delta, Vectors and others. Then additional tutorials will be used for teaching how to analyze a performance in Sports and other human activities. It is like having a Cyber University of Biomechanics at your fingertips. Please feel free to copy the material and download the video files. Use this material in your classroom or your organization to have first hand experience with Biomechanics. Download the APAS system to any notebook or desktop and organize your curriculum to allow students to have a first class experience with this great field. You may teach also other disciplines utilizing this material. Imagine teaching Mathematics, or Biology, utilizing real life situation and use Biomechanics as the tool to teach these disciplines. Woud't children like to learn about displacement and velocity by utilizing Biomechanics to analyze the most recent Olympic events or the European Soccer Championship? The video files are large files and should be played with the MS Media Player. These video files are compressed and this why their quality is not as good for digitizing. However, it allow the teaching process to be practical within reasonable file sizes. Of course, you can create your own files and it will be great if you will share these files with others through the Internet. Capture cards becoming less and less expensive. The I-Omega 60hz capture card can be purchased for $150. You can purchase it through the Internet by linking to http://www.pricewatch.com . This site will link you World Wide to the place to buy any hardware for the least expensive price. This is amazing, when only few years ago this technology would cost Thousands of Dollars. The material will get better and better. In some cases you will find some spelling mistakes or incorrect sentences. This is due to the fact that my native language is not English. My co-workers will take care of that with time. I apologize for that. However, the material is first class and you could not get it anywhere else. I was the first one that started all this electronic Biomechanics. My publications going back to 1968 when I used a Sonar digitizer to digitize the knee joint angle and transmit the coordinates data from a modem at 300 Bauds, in my kitchen in Amherst Massachusetts, to Dartmouth College at Hanover New Hampshire. Dartmouth was the only University in the World to have a Time Sharing system. Also, the Basic Language was invented at Dartmouth College where I learned it from the inventors, Kemney and Kurtz. The original APAS System I was written it in the Basic Language. I will appreciate any feedback and corrections.

The System's inventor, Dr. Gideon Ariel, developed the first on line electronic digitizing system for reducing each picture in a film sequence, and later from a video, into its kinematic components. Since 1971, Ariel Performance Analysis System has assisted medical professionals, sport scientists, and athletes, to understand and analyze movement using its advanced video and computer motion measurement technology. It surpasses all other video systems for quantitative accuracy and scientific excellence for the most cost effective choice in major medical and research and educational institutions around the world. The Ariel Performance Analysis System (APAS) is the most advanced computer-based system for the measurement, analysis, and presentation of movement performance. It is the only technology exist today to allow video as well as markers and none markers system to integrate movement and its components. The study of the motion of living things is known as "Biomechanics" and it has evolved from a fusion of the classic disciplines of anatomy, physiology, physics, and engineering. Biomechanical quantification are based on Newtonian equations and the APAS analytic technique models the human body as a mechanical system of moving segments upon which muscular, gravitational, inertial, and reaction forces are applied. Although the system has primarily been used for quantification of human activities, it has had many industrial, non-human applications. The computerized hardware/software technique provides a means to objectively quantify the dynamic components of movement and replaces mere observation and supposition. The APAS demonstrates significant advantages over other common approaches to movement systems.
The ability to record the activity as a picture has a number of advantages:
Applications of the APAS usage include many areas of interest.
