Advantages - Advantages - Ariel Gait Analysis System

You decide how to analyze

APAS/Gait does not dictate how you should run an analysis. You can choose any of the following marker sets: Helen Hayes Hospital, Keith Vaughan, or Chung (Seoul National University). And some other marker sets that can be used with fewer cameras.

APAS/Gait was designed to maximize analysis efficiency and minimize any errors. The system integrates video with markers sets. It allows the investigator to select any of the markers sets available and visually compare results both in the renderer and with the original video.

This allows endless possibilities for visual validation of experiments:

The system does not dictate how you should analyze your data. You are in control and can make it as easy or as sophisticated as you want.

Render and compare in Real-Time

APAS/Gait contains a real-time rendering system. Rendering can be performed in any resolution supported by your hardware and looks great on 65000 colors or more. 

The software will maximize rendering performance on your hardware. It automatically uses interpolation between the different frames to achieve the smoothest possible animation on your hardware.

An example: suppose you play a 2-second sequence containing 100 frames, captured using a PAL system at 50 frames per second. When rendering this animation and setting the total length of the animation to 60 seconds, you would normally achieve a frame rate of about 100/60 = 1.67 frames per second. 

But APAS/Gait uses a different strategy: if your hardware allows you to achieve a full 50 frames per second, the software will automatically interpolate all segment orientations: it will calculate 60 * 50 = 3000 new orientations for each segment: this effect is immediately noticeable to the user. Instead of watching the animation play at a jerky 1.67 frames per second while wasting your system's CPU-time, you will be able to exploit your hardware to the fullest and examine your animations in super-slow-motion at a 50 frames per second frame rate.

Inexpensive

Where the average cost of any gait system is $100,000 and up, APAS/Gait is priced only $1,995 . You can download the system for free and try it for yourself. Try it, use it, and then let us know.
