This manual is an introduction to the GARTerBelt toolkit. I, Jesse, am your guide. Coincidentally, I am learning this toolkit along with you, so if things don't make sense then it is because I have no idea what I'm talking about. I will be expanding this documentation as I learn more about the system and about GART and HTK. Bear with me! Feel free to direct questions to jsmith99 at cc dot gatech dot edu.

According to the GARTerBelt release notes, this toolkit is a “work flow program for handling creation and testing of Hidden Markov Models using the GART framework.” GARTerBelt makes GART easier to use by providing a GUI (Graphical User Interface) to aid in the manipulation of the files and data involved in gesture and activity capture and recognition. These files and data can be broken down into the following:

• Libraries: Collections of sample data. They can be imported from disk or exported to disk through GARTerBelt.
• DataSets: Subsets of Library samples matching certain search criteria. They can be imported, exported, or created.
• Prototypes: Base topologies for Hidden Markov Models from which Models are created. They can be created or exported.
• HMMSets: Sets of Hidden Markov Models that were generated from a specific Library/Dataset and Prototype combination. They can be created or exported.

• You must have Eclipse downloaded and installed, as well as the Subclipse SVN plugin for Eclipse.
• If you have not already done so, follow the instructions on checking out the GART repository at the CoC Research Subversion Repositories. If you do not have permissions to check out the repository, then contact the current administrator of the repository. At this time, the administrator is Jung Soo Kim .
• Obtain permissions to check out the GARTerBelt repository from Jung Soo Kim and check it out in a similar manner to the GART repository.
• In the repository, there are three packages: Demo2, Demo3, and Trunk. The verdict is still out on which is the correct package. More to come…
• GARTerBelt should show up in your list of packages in Eclipse.
• Download and install JUnit version 3.8 or higher. It will want to live in the Java ClassPath, which was /usr/share/java on my machine. You should check the classpath before going through all that work, as JUnit 3.8.1.1 was sitting there grinning at me after all that work of trying to install it.
• You are now ready to use GARTerBelt!
