The Virtual APAS


Imagine that you are sitting in front of a computer screen, connected to the whole World through the Internet, with the ability to link to any other biomechanist, as yourself, to read/view their shared folder for any type of data you wish.

Imagine that in the 2000 Olympic Games in Sydney, you can capture any activity from the TV while sitting in your Easy Chair.  As long as you capture the video feed from different angles which NBC usually shown, as demonstrate above, and as long as you know dimensions of known objects such as the track width or the height of the number markers, and even the size of the athlete, you will be able to calculate accurate 2D and 3D coordinates. Even if the cameras pan, zoom or tilt, the APAS PZT will allow you to calculate the coordinates of the body's joints and then analyze the Kinematics of the movement.  During the Games, make sure you log into our Website at: 
/  and see the results. And if you are willing to share your data, the whole World will enjoy the results which will be given fast and quick.

This is what the Virtual APAS is. The 21st Century in Biomechanics. 

The following are only few of the function that you can perform:

  • Locate and download your favorite Biomechanical Data from one convenient, easy-to-use interface.
  • Software that allows users to share Biomechanical libraries with each other no matter where they are located. APAS-virtual provides a search capability for videos, 3D/2D Files capability for users to communicate in forums of like interest.
  • Each Biomechanist is a download/upload source
  • Each User Computer, when it is on, it becomes a shared directory

The procedures may follow the following scenario:

  • A user records and stores Video file in a specific folder on his or her hard disk
  • A central directory maintained by APAS.com keeps track of which users are logged on, cataloging by title and researcher/biomechanist the activity in each user’s special folder
  • A user searches through the APAS.com directory for a desired activity or sports. Once the activity is downloaded it can be used for further analysis or observation. This file can also be sent to another person as e-mail or attachment
  • Any user folder can be shared with the rest of the World
  • APAS.com monitor and publish the catalogue of activities and sports world wide

So, lets see how its work:

The Virtual Folder Site is at:

Lets connect through wireless to this  site.

My desktop in my office in California is on.  The Biomechanic Share folder contain data base of athletic activities from the the Olympics Games in Atlanta.

In order to connect to this Virtual World first you need to install the Java engine.  You can do it from the following site. (Click Here).

After installing the engine, and you need to do it only once on your computer, you can proceed to the demonstration. (Click Here)


The Wireless APAS and on Hand Held Compuers

  Imagine a Golfer standing on the green and swing his golf club. A video camera taking video of this swing. The video is capture directly to the hard disk in real time. Then a compressed sequence is transmitted automatically through a wireless modem to the local server. From the local server the sequence is digitized by any location in the World through the Internet. The velocity of the Golf Club is determine in few minutes and the results are transmitted back to the server. The server automatically call the cellular web phone which the Golfer carry. He pick the phone click the web bottom and the velocity of the club head as well as other kinematics parameters are shown on the small color screen on his phone.

  The golfer want to retrieve a particular video frame where impact occurred.  He click the frame number and the video frame is transmitted from the server superimposed on the particular stick figure.

  Welcome to the wireless APAS !!! Check the following links:

  You must install the JAVA system first.  JAVA is the modern computer language of the Web and any application which require interactive real time, needs to have JAVA installed.  You can install the Java free of charge from:
