Ariel Dynamics, based in San Diego, produces computer-based, biomechanics analysis tools and systems primarily for sports. Founded in 1968, its other applications include gait analysis, workplace design, product testing, prosthetic and orthotic fitting, and neurological studies. Its human performance analysis systems and computerized exercise systems are the result of more than 25 years of research are covered by various patents and copyrights. The system quantifies motion so that performance can be corrected or compared to mathematical models. As speed, memory and peripherals of computers have expanded and as the resolution of video cameras has increased, so has the functionality of the system. Ariel Dynamics continues its research to provide clinicians and businesses with improved and relevant motion data.
