what are the Scaling Variables ?

do I vary the
-> whole body or according segment
lenght and mass respectively

can I vary the
-> fat percentage
-> age
-> gender

Hello Costa,

In theory, it is up to you to implement any type of scaling you want. But
since you will probably be using the model from the repository, you can use
its integrated scaling methods which are:

Standard

Uniform

Length-Mass

Length-Mass-Fat

You choose which one by including the proper any file.

Also, on a per-segment basis, you can be more specific using the AnyMan.any
file and modify the parameters for your own. You can look at a model such a
GaitVaughan (repos 7.0) or Gait3D (repos 6.2) for examples.

In GaitVaughan, you can see a section such as:

 //Choose between scaling laws

 //#include "..\..\..\Body\AAUHuman\Scaling\ScalingStandard.any"

 #include "..\..\..\Body\AAUHuman\Scaling\ScalingUniform.any"

 //#include "..\..\..\Body\AAUHuman\Scaling\ScalingLengthMass.any"

 //#include "..\..\..\Body\AAUHuman\Scaling\ScalingLengthMassFat.any"

 Scaling = {

   //This is the file which set the segments lenghts

   #include "AnyMan.any"

 };

On top of that, there are a few webcasts on this subject. After you
register/login to the site, you can go to:

HYPERLINK
"http://www.anybodytech.com/196.0.html"http://www.anybodytech.com/196.0.html

And you should be able to find:

Scaling strength in human simulation models

Anthropometric Scaling of Musculoskeletal Models

Also, fairly related to this, there’s the GaitApplication, which helps
scaling a model according to markers (Mocap data):

HYPERLINK
"http://tech.groups.yahoo.com/group/anyscript/files/GaitApplication2/"http:/
/tech.groups.yahoo.com/group/anyscript/files/GaitApplication2/

Finally, although the model repository is an important part of Anybody, it
isn’t in fact a product of Anybody tech itself. It is officially developed
and maintained by the Anybody Research Project. So you can find most
information on publications and model specification, along with the actual
repository, from the their website:

HYPERLINK "http://anybody.aau.dk/"http://anybody.aau.dk/

Hope this gets you started,
