With the use of this tool, you will be able to translate strings written with HamNoSys (Hamburg Notation System) to SiGML
and automatically create an xml script/ file of the given strings.

To let the Avatar animate the desired sign language word, you have to give instructions, to the avatar on how to do particular actions.
This is done with the use of a SiGML file.

Well, you can use the contents of the generated file with the tool that is accesible on following URL: Signing Avatar
