Why should you select the Ariel Performance Analysis System?
All Motion Analysis Systems were developed for the purpose of analyzing movement
The basic framework for all modern systems consists of hardware and software. All companies provide hardware consisting of either off-the-shelf products OR their own proprietary items which they manufacture. Every company includes software to operate the computer as well as follow the programmed biomechanical instructions to analyze the data and present the results in useful, acceptable formats.
How can a Consumer evaluate the choices presented?
Since all companies engage in marketing efforts to sell their products, consumers must evaluate the efficacy of the product claims against reality NOT because a well-known individual or a sales person makes the claim. Everyone has heard the joke about knowing the sales person is lying if the lips are moving. The Buyer must acquire accurate information in order to differentiate between sales hyperbole and truth. "Caveat emptor" -- "let the Buyer beware" extends beyond the pig in the poke.
Get the BEST for LESS
Your biomechanical system must be ACCURATE, VERSATILE, and FUNCTIONAL. You should demand the best, get the best, and for the best price!! Usually getting the BIGGEST BANG for the BUCK is the consumer's first thought regardless of the product. You want to buy the BEST biomechanical system AND at the BEST price. This document should help to focus on some of the realistic considerations associated with biomechanical systems currently offered.
Remember the old adage that "a fool and his money are soon parted!" Just because a three-piece suit or a "big name" consultant tell you that their product is good does NOT make it true. Conduct an open-minded, point-by-point comparison with the Ariel system. Test their claims against those make by Ariel.
Correct, honest, and accurate information will lead you to only one conclusion:
The Ariel Performance Analysis System (APAS) is the Best !!!

If you desire to use the optional CAPDV software module for real-time video data collection, and the Ariel Analog Module to collect Analog data (EMG and/or force plate) simultaneously, this will require two separate computers. One computer would be used for real-time collection of video data while the second computer would be used for real-time collection of Analog data. Once the data is collected, either data set (video and analog) can be transferred, processed and analyzed on either computer. A single computer is currently not capable of supporting the high demand of collecting video and analog data simultaneously.
There are two general formats for video; PAL (European standard) and NTSC (United States standard). All APAS software supports both PAL and NTSC video. Whether the APAS is PAL or NTSC compatible depends upon the video hardware. All APAS hardware systems sold in the US are provided with NTSC capture cards and cameras. If you require a PAL video format system, Ariel Dynamics can supply PAL compatible capture cards pre-installed in the computer, however, it is very difficult to obtain PAL format video cameras in the United States. Therefore, in this instance, we recommend that the customer purchase the PAL cameras locally.

We at Ariel Dynamics Inc. hope that you have had an opportunity to examine various motion analysis systems. If you did, you will find that the motion analysis system developed by Ariel Dynamics have demonstrated the latest technological advancement. This system was developed originally by one of the pioneer in the fields of motion analysis and modern exercise equipment, Dr. Gideon Ariel. As founder and president of the company, Dr. Gideon Ariel has set standards for the biomechanical industry which has developed since his efforts in the 1960's.
The Ariel Performance Analysis System (APAS) is the most advanced computer-based system for the measurement, analysis, and presentation of movement performance. 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 treats the human body as a mechanical system of moving segments upon which muscular, gravitational, inertial, and reaction forces are applied. Although the system has been used primarily for quantification of human activities, it has had some 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. Except for specific applications requiring EMG or kinetic (force platform) data, it is non-invasive. No wires, sensors, or markers need be attached to the subject.
The ability to record and store the activity as a picture has a number of advantages:
The APAS has been utilized in many areas of interest, study, or work. Applications have included, but are not limited to the following:

Population of users
The Ariel Performance Analysis System (APAS) is considered to be one of the most accurate system available today. Independent studies, by various organizations and institutions, have shown the APAS to be accurate, valid, and reliable at high levels.
For example, a study by MOCO, Inc. performed for NASA, demonstrated that the APAS was as accurate as the Ascension Flock Of Birds. The Flock of Birds system is a very accurate direct measurement position device utilizing wires and transmit-receive electronics.
Additional studies by NASA determined that the Ariel System's accuracy was superior even under constrained conditions such as with data collection under water and wide angle lenses. Another study, published in the Arch. Phys. Med. Rehabil, demonstrated the accuracy of the APAS. Additional studies are available.
Responses from our customers to question by the Biomch-L list on the accuracy of the APAS system, illustrates our customers satisfaction.
The APAS is easy to operate with logical, step-by-step
procedures accompanied by an on-line help screen. However, one of the best ways to
evaluate the ease and simplicity of operating the APAS is to read the manual. The APAS manual describes all the available
functions and how they are performed. Not only will you be convinced that there is no
system as extensive nor as sophisticated but, at the same time, you will discover the ease
with which you can use the APAS.
The APAS is integrated in an off-the-shelf
Pentium/586/686 based computer. No unique, specially-designed hardware is required.
The APAS can be extended to an additional IBM compatible computer for use as a
Workstation. In addition, the Ariel system runs on any notebook computer making it easily
portable. A notebook computer allows data to be acquired anywhere. Regardless of which
computer is selected, the acquired data can be transferred among geographically distant
sites via the Internet or within the Laboratory on any LAN system.
The menu-driven system allows the user to follow on-screen
directions. In case a question arises, pressing the ? key immediately produces a help
screen. In addition, an on-line manual is
available. The Internet interface allows users to communicate through Forums or user
The APAS is a modular system using off-the-shelf computers, A/D boards, VCR, any additional computer peripherals, as well as cameras with speeds of 60 Hz to 10,000 Hz. In other words, there are no specialized, proprietary hardware requirements. If your printer breaks or you want a larger color monitor, you can purchase the new component at any computer or video store. If you damage or break some part, we can ship a replacement within 24 hours and you will need merely to insert it. No other company in the world in this business can perform for you like this.
Also, you may purchase additional modules at different times. All you will have to do is plug it into the system and you ready to resume work.
When upgrading hardware, you will not have to change the
entire system, but only the specific part. The other parts are still good which makes this
is a very flexible and economical system.
The Ariel Performance Analysis System (APAS) was designed
to be portable. The desk top computer, monitors, VCR, and other peripherals can be
arranged on a cart for easy mobility. The notebook computer option affords even greater
versatility. Because the notebook and the cameras are light-weight and readily
transportable they can be taken virtually any place for data collection and analysis. For
example, EMG data can be collected at any site with the notebook and, subsequently, the
data can be transferred to the desktop system. Communication between the main desktop
computer and the notebook or another computer located elsewhere in the world can be
accomplished in seconds via the Windows-95 interface, Internet linkage, and/or through
Local Area Network (LAN). The APAS was designed from its conception for on-line
communication and the Internet provides a natural "central nervous system" as
the interface between local and global integration.
The staff at Ariel Dynamics, Inc. is continuously
developing new options and programs for the APAS. These upgrades frequently involve newly
available electronic technology, new mathematical algorithms, or user requested software.
Customers anywhere in the world can download the new software at no additional cost
directly from our Internet server site. Downloading is a simple process and the upgrading
procedure requires no specialized software or hardware expertise.
Most of our personnel are trained in various fields such as
Exercise Sciences, Biomechanics, Nuclear Physics, Biomedical Engineering, Computer

The Ariel company has always blazed the trail in the area
of Biomechanics. The Ariel company was the pioneer in providing the first computerized
electronic QUANTIFICATION of human and biological motion, the first biomechanical SERVICE
commercially available to industry, and, most recently, the first computerized
biomechanical PRODUCT in the world. INNOVATION, CREATIVITY, KNOWLEDGE,
and effective UTILIZATION of the NEWEST TECHNOLOGY available have maintained
the Ariel company and its products on the leading edge. Other companies merely copy or
struggle to keep the pace. Time after time, however, Ariel technology wins by wide margin.
The APAS is an "Open" system. Any data
collected with the APAS, whether video, kinematic, kinetic, or analog data, such as EMG,
force plate, etc.) can be downloaded to virtually any program. Most formats are supported,
including ASCII, Spreadsheet, DIF, as well as many graphic formats, such as
etc. It is the only system in the world that can interface with other popular programs as
Excel, Lotus-123, Access, Word for Windows, Microsoft Office, Coral, and many more.
The APAS was Internet compatible before the Internet! As early as 1976, data was transmitted through a modem from the Montreal Olympic Game site to our office in Amherst, Massachusetts. The data was analyzed and electronically transmitted to the Olympic Site and the Olympic Committee center. Images were transmitted in ASCII codes and reconstructed at the receiving site. Not only was this a laborious effort and time consuming task but extremely expensive in telephone toll costs! However, Ariel Dynamics will always be able to proudly declare: "We were ahead of our time". Today, of course, the Internet has became the core of our communication system. We are connected with hundreds of customers and produce multi-site research from the US to Denmark, France, Israel, Japan, and other locations. You can link to Dr. Ariel's presentation at the International Society of Biomechanics meeting in Finland to see how Ariel pioneered this field.
Video data can be collected in one country and transmitted
through the Internet to another site for quantification. The resulting analytic results
can be transferred to another country or any site on the Internet for presentation or
data-base compilation. Final results and documentation can be transferred from the various
processing sites via the Internet to headquarters. All interaction via the Internet can be
performed over local telephone, LAN lines, or network service providers for minimal costs.
The APAS is the only system in the world that can accomplished this level of Internet
The software upgrade, as mentioned previously, is provided
to customers without charge. The hardware challenge is slightly more difficult. As
everyone knows, electronic developments are advancing at lightning speed. In most cases,
hardware advances primarily affect the computer's processor and memories. The customer can
purchase virtually any compatible computer, transfer the video boards, frame grabber,
cameras, VCR, etc. from the older system and Ariel Dynamics will make every possible
effort to ensure that the Ariel software and the new hardware components will be
compatible. In those unusual situations, some off-the-shelf computers may not work
correctly at the beginning. In those situations, Ariel Dynamics and its staff will assist
the customer to facilitate the upgrade for little or no additional cost.
As noted previously, hardware improvements and new products
are continuously being introduced to the market. If a customer wants to replace his/ her
equipment, Ariel Dynamics will assist in these efforts and charge only for the hardware
equipment costs. In many cases, a customer can frequently sell his/her equipment to
another organization and replace them with newer models from Ariel Dynamics.
Ariel Dynamics provides an amazing, unique opportunity for their customers. When you purchase an APAS, Ariel Dynamics will install any number of Workstations in your lab or institution. This means that you get more systems for the price of just one APAS. The advantage of this offer is that you could have a master system in your office and provide students or technicians with additional units as workstations. The only different between the main system and the workstations is that analog and video data cannot be collected with the workstations although all other analytic processes can be performed.
In other words, you can purchase just one APAS yet extend the capabilities to multiple computers. With one APAS purchased for the basic price of approximately $20,000.00 (US), extending to 5 additional Workstations reduces the cost per station to approximately $3500.00. No other company can match this offer.
The motivation for Ariel Dynamics to provide this
opportunity is straightforward. Budgetary considerations often prohibit purchasing more
then one system. By providing the ability to increase productivity, more research can be
pursued. When you present your research, perhaps we will benefit from any credit described
in your experiment. In addition, this provides contact with the scientific environment
which is both a corporate and personal interest.
Initially, every effort will be made to repair your system via modem. The majority of problems are resolved in this manner. However, occasionally the customer will need to return his/her equipment.
When a customer has such a repair need, Ariel Dynamics can
send equipment replacements immediately by Federal Express. You will then need to send
your equipment for repair. Service normally requires one day to determine the location of
the damage and replace it. Then your equipment will be returned. This means you will
rarely be down more then 24 hours.
By purchasing the Ariel Dynamics APAS, you join the leaders in your field as well as organizations such as NASA, Olympic Committees, Research Laboratories, and leading Universities around the world. For selected users, see the World Wide Users section on our Web Site. In December 1995, the following International customers purchased the APAS:
. . . and other institutions.
