In addition, many groups outside of ICT use some of the toolkit components, most notably [[SmartBody]] and [[Watson]]:
* University of Reykjavik
* German Research Center for Artificial Intelligence
* ArticuLab at Northwestern University
* Telecom Paris Tech
* Affective Computing Research group at MIT Media Lab
* ICSI/UCB Vision Group at UC Berkeley
* Human-Centered, Intelligent, Human-Computer Interaction group at Imperial College
* Worcester Polytechnic Institute
* Microsoft Research
* Relational Agents group at Northeastern University
* Component Analysis Lab at Carnegie Mellon University

Getting Started

Please go to the [[Support]] page for instructions on how to obtain the toolkit. This page will also give you further guidance on how to install and run the provided scenario.

For navigation on this website, please use the menu on the left. Each of the listed sections is described below:
* '''[[Architecture]]''' - Gives an overview of the toolkit architecture, based on the ICT Virtual Human Architecture.
* '''[[Components]]''' - Lists all modules, tools and libraries that make up the toolkit and links to available documentation and third party enhancements.
* '''[[Tutorials]]''' - Lists all available tutorials, including how to run the provided examples and how to create your own virtual human.
* '''[[Projects]]''' - An overview of some projects that use technology included in the toolkit, see also below.
* '''[[FAQ]]''' - Frequently Asked Questions about the toolkit in general and all of its components in detail. Also contains a glossary for often used terms and acronyms.
* '''[[Support]]''' - An overview of available support.
* '''[[Links and Papers|Papers & Links ]]''' - List of links to related sites.

Users

Users can run all the needed components in order interact with Brad, the basic example character provided with the toolkit. After obtaining the toolkit, see the instructions on the [[Support]] page on how to install it. When the installer is done, you get the option to immediately start the Launcher. With the Launcher, it should be as simple as clicking the first Launch button (in the Run Checked row under Run It All), then quickly clicking OK on the Gamebryo settings windows, and waiting for about 30 seconds for all components to launch. Note that Gamebryo needs to be up and running before SmartBody can be launched. When using the Run All functionality, the Launcher will start Gamebryo and wait 15 seconds before loading all other modules. It this is not enough time, launch Gamebryo manually, uncheck Gamebryo in the Launcher and then Run All. When all the non-tool rows in the Launcher are green, it means you are ready to start interacting with Brad. Brad is a very basic character and shows off some, but not all, of the toolkit elements.

Many windows will have popped up, but the only ones you need right now are the Gamebryo window for the graphics, and AcquireSpeech to type in questions. In AcquireSpeech, go to the Player tab, type your question in the Text field, and click the associated Send button or hit enter. Brad should respond to your question by talking back. By default, Brad uses the Text-To-Speech voice that comes with Windows, so depending on your windows version, you might hear a very outdated computer voice, or a woman's voice. Brad is authored to answer all your general questions about the toolkit. Be aware that he only has a general overview of the toolkit; he does not serve as an interactive tutorial or tutor.

In the bin/sbmonitor folder, there is an application called sbmonitor.exe. This tool is the Smartbody Monitor and is used for debugging and interacting with any Smartbody process that it connects to. While the toolkit renderer is running with Smartbody, start the sbmonitor.exe and press the orange button in the top left corner. After a few seconds, you will be connected to the Smartbody process within the toolkit. There are many dialogs and tools that you can use to interact with Smartbody from within the Smartbody Monitor. The Utils tab on the right side of the screen and the menu options under "Tools" on the toolbar provide many options for interacting with Smartbody.

For more detailed instructions, including troubleshooting, on how to run the provided example, please see [[Tutorials:Run Example Domain|here]].

Authors

Authors can create their own virtual humans. They should first get familiar with the basic example character provided with the toolkit: Brad. Brad shows off some of the toolkit elements, in particular natural language interaction and nonverbal behavior. The graphics are simple, the default voice is outdated, and vision and speech recognition are not integrated.

Once you are familiar with the Brad character, you can read up on the technology behind the [[Components]] and some of the [[Tutorials]]. The documentation of these is a work in progress.

Creating a character consists of various elements:
* Natural language, the [[NPCEditor]]. See below for some basic instructions.
* Nonverbal Behavior, the [[NVBG|Nonverbal Behavior Generator]]. You can edit some of the language to behavior rules in C:\vhtoolkit\core\nvb_generator\NVBGenerator\xslt\rule_input_brad.xml. In this file, keywords are associated with certain animations.
* Animations, using a third party application like Maya or 3D Studio Max, in combination with [[SmartBody]] exporters.
* Character and background models, using a third party application like Maya or 3D Studio Max, in combination with [[Ogre]] exporters.
* Textures, using a third party application like Photoshop or Gimp.

Of these, the NPCEditor is the easiest to start with. In the Utterance tab you see questions a human user can ask on the left, and the possible answers on the right. Questions are linked to answers with a certain value from 1 to 6. Usually there are only links with value 6. When you select a question, all answers linked to that question turn green. You can select multiple questions and answers by holding control, thus creating sets of links. If sets are not mapped completely 1 to 1, elements from one set that are only partially linked to elements in the other set will be displayed yellow. If you want to create a 1 to 1 mapping between the sets, select all yellow rows on both sides and set the link value to 6, either by selecting it at the bottom or by using CTRL + 6. Similarly, you can make new links between questions and answers by selecting them and setting the link value. You can add either new questions or answers with the Add button. A new, empty line appears, which you have to select in order to fill in the text field. Be aware that on the answer side, the Compile / Script section might hide the text field. You can drag the compile section down and ignore it.

Try first to extend the Brad data file (called a plist), before you create a completely new character on your own. First, think of a question Brad cannot currently answer. Try out that question and confirm that Brad says something like "I don't know.". Then, add the new question on the left. All components can stay up for this; you can edit the plist in real time. Also create the answer on the right. Be sure to set the Speaker value to Brad. Now, select both question and answer, and make sure no other elements are selected. Hit CTRL + 6, to link them together, and save your file. Ask the same question again, and Brad should now give the answer you just created. From here on you can let your creativity flow. Have fun!

Developers

Developers can extend toolkit components, use toolkit components in their own systems, or use their own components within the toolkit. First, read up on the [[Architecture]] and [[Components]], and read the [[Tutorials:Develop a New Module|tutorial]] on how to develop a new module. The documentation of these is a work in progress.

The toolkit architecture consists of modules communicating by message passing. The [[Messages]] section defines some of these. You can use the [[Logger]] to get more detailed and practical information. Replacing or using a module means adhering to the existing messaging interface.

If you are interested in extending the components within the toolkit, we would love to hear from you. See the [[Support]] page on how to contact us. Note that not all provided software is open source, and that not all open source software is accessible from a repository. [[SmartBody]] is a SourceForge project, accessible [http://sourceforge.net/projects/smartbody/ here].
