APAS demonstrates significant advantages over other common approaches to movement systems:

	First, 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.
	Second, it is portable and rarely requires any modification of the performing environment. Cameras can be transported to the site and positioned so as not to interfere with the subject.
	Third, the scale and accuracy of measurement can be set to the levels required for the activity being performed. Video equipment technology currently available is sufficiently adequate for most applications requiring accurate motion analysis and is normally the least expensive option, particularly when two or more cameras are needed.

Video-based

The ability to record the activity as a picture has a number of advantages:

	It allows the scientist to make intellectual decisions regarding the joint center at each frame rather than using markers attached at the skin's surface.
	Subsequent quantification would be possible since the video can be re-examined at any time.
	Stick figure results can be overlapped with the video pictures for effective result presentations.

Areas of interest

Applications of the APAS usage include many areas of interest.

	Sport or athletic applications have included volleyball, soccer, American football, tennis, track and field events, horse racing and jumping, and golf.
	Medical research is using the APAS to quantify movement in Parkinson patients with and without drugs and before and after surgical procedures.
	Job quantification
	task improvement,
	post-injury assessment
	employment evaluations
	risk assessment,
	worker's compensation
	disability evaluations
	ergonomic evaluations of job tasks
	job standardization can be useful in the workplace.
	Industrial applications include product design, analysis, and improvement as well as such things as manufacturing hardware performances such as piston movement accuracy.
	Artistic endeavors, such as playing the violin, the harp, and the piano, have been examined biomechanically by APAS applications.
	Mammalian research has examined thoroughbred race horse performance, feline locomotion, and monkey jumping performance.
	Forensic analysis have included injuries sustained in football, gymnastics, horse racing, and running shoes.
	Space Research have included number of research studies at NASA.
	Rehabilitative usage include pre- and post-hip replacement functioning, gait analysis, and comparisons of bilateral functions.
