Introduction

APAS/Lite is a subset of the full version of APAS. It is provided as Freeware (costs you nothing)  and allows most functions to be able to perform a complete biomechanical analysis of any movement, human, animals or objects.

For example, refer to the following study: 

KINEMATIC ANALYSIS OF HURDLING PERFORMANCES AT 2000 UNITED STATES OLYMPIC TRIALS

This paper was accepted for presentation in the ISBS meeting in San Francisco (ISBS 2001). This study was conducted entirely with APAS/Lite! If APAS/Lite is good enough for Olympic Performance analysis, it may meet all your requirements.

Some of the differences between APAS/Lite and APAS are:

  1. No support for digital cameras
  2. No support for analog input 
  3. No EMG or Force Plate Analysis
  4. No Trimming module
  5. Some functions in the Filtering Module
  6. Some functions in the Display Module

So, the first question you may ask is: "If I cannot capture video files, what use is APAS/Lite at all?  Without the video, I cannot digitize the raw data".

The answer to this question is relatively simple. You can use any of the "off-the-shelf" programs such as Ulead, Pinnacle, and many others that are included with the capture card to capture and trim your video data. Why would you want to pay thousands of dollars for something that is already included with the purchase of the digital capture card and costs between $25 and $75?  Do you want to be one of the crazy people that purchase Peak Performance, Motion Analysis, Vicon or Qualisys systems and pay hundreds of thousands of dollars to companies that sell you old technology? Then you you find out you have to keep paying these companies for services and maintenance to support their executives driving their Mercedes Benzes and flying first class all around the world....Today all this technology is available for few hundred dollars !!! Don't be a sucker !!!

The APAS Trimmer module has been added to the APAS software to allow more convenience in handling the video, however, this is one of the differences between the APAS/Lite (freeware) and the APAS (paid) software.  Of course you can update APAS/Lite to the full APAS System at any time. This will not cost you much. A full APAS system sells for only $5,000 !!!  We at Ariel Dynamics Inc. spent millions of dollars over the last 30 years in development and R&D to create the APAS System. In fact the APAS system is the first ever commercial Biomechanical System in the World!  It was first introduced 1968, long before the PC. At that time APAS was running on mainframes and mini computers such as Digital Equipment and Data General.

I was the first one to use electronic digitizing.  This involved manually digitizing coordinates from a rear projection film tablet utilizing a Sonar Pen that I developed in 1968. The first available "time-Sharing" at Dartmouth was used to send data through the phone line.  Believe me, at that time it was a kind of miracle. Check here for this invention.  

So, let's get started...
