This program demonstrates the simple use of the Hidden Markov Model Toolkit (HTK) Java Interface (HTKJI). It allows training gestures take up from a Wii Remote controller. The communication between the Wii Remote controller and the pc is handled by the wiiusej library , which is included in this package. The gesture are trained and recognised by using the HTKJI which is also distributed with this package, but HTK is not included, because its licence doesn't allow it (Thus, it must be downloaded and installed separately.).

 Running the Demonstrator

1. Download the WiiDemo zip-package.
2. Unpack it.
3. Connect the Wii Remote with your pc.
4. Open the Windows command line and enter the WiiDemo directory.
5. Launch the WiiDemo by typing: java -jar WiiDemo.jar
6. Press "Connect Wii Remote".
7. Train gestures:

• Set the workspace where the training files should be placed.
• Set the name of the gesture that should be trained.
• Record (about 15 - 20) gestures. (Note: A button B press event indicates a gesture start and a button B release event indicates a gesture end.)
• Set next gesture name and take up the gesture examples and so on.
• When you finished recording gestures press "Start Training"

8. Recognise gestures:

• Set the workspace where the Markov Models and training files are placed.
• Record a gesture. (Note: A button B press event indicates a gesture start and a button B release event indicates a gesture end.)

The application is published under the terms of the GPLv3 licence.
