Training Project Menu

To access the context menu for a training project, open an existing solution in VGB (File > Open Solution) and right-click on a gesture project in the Explorer.

The Training Project menu displays options for adding clips and building the gesture detector.

Figure 1.  Training Project menu

The following options are available for the training project.

Menu Option	Description
Add Clip	Adds one or more clip files (.xef) to the project. This will create an associated .vgbclip file for tagging metadata, if no such file exists.
Build	Builds the gesture database file (.gba). This trains the gesture detector and outputs a single project database (.gba) which can only be used for analysis or Live Preview testing. This option is disabled when another build or analysis is in progress.
Save	Saves all changes to the project (.vgbproj), including clip references.
Remove	Removes the project from the solution.

Training Project Settings

The training project settings enable you to modify project property values. These values affect gesture training results and performance. Available settings depend on the Machine Learning technology used by the selected gesture project. For more information, see Machine Learning Technologies.

Figure 2.  Training Project Settings

Parameter	Description
Name	Settings property name. The names listed depend on the machine learning technology used by the project. Use Hands Data: When set to true, VGB uses hand states (open/closed/lasso) to train and detect gestures. Ignore Left Arm: When set to true, VGB ignores left arm joints (ELBOW_LEFT , WRIST_LEFT, HAND_LEFT, HAND_TIP_LEFT, THUMB_LEFT) to train and detect gestures. Ignore Right Arm: When set to true, VGB ignores right arm joints (ELBOW_RIGHT , WRIST_ RIGHT, HAND_ RIGHT, HAND_TIP_ RIGHT, THUMB_ RIGHT) to train and detect gestures. Ignore Lower Body: When set to true, VGB ignores leg joints (KNEE_LEFT, KNEE_RIGHT, ANKLE_LEFT, ANKLE_RIGHT, FOOT_LEFT, FOOT_RIGHT) to train and detect gestures.
Value	Assigns the value to the settings property.
Type	Displays the type associated with the settings property.
Export	Export the project property values to a file. Use this control as follows: Click the Export button. The Save As dialog window is displayed. In the File name: box enter the name to use for the file. If the project name is "GolfSwing", the default file name is "GolfSwing.fid".
Import	Import the project property values from a settings file (.fid) that you select. Use this control as follows: Click the Import button to display the Open dialog. Enter the filename in the File name: box (such as "GolfSwing.fid").

Training Project Results

While building, training progress will be displayed in the Output pane for a gesture project. When complete, the resulting database (.gba) can then be loaded in VgbView on the console for live testing (File > Live Preview), or it can be used to analyze the gesture detector against a collection of test clips (for more information, see Analysis Project).
