Subject Preparation tools

You must create a Vicon labeling skeleton template (.vst file), or import an existing one, for each type of subject whose motion is to be captured and analyzed in Nexus. You only need to do this once for each type of subject. Sample .vst file are provided under the Nexus model templates folder (by default, C:\Program Files\Vicon\Nexus2.#\ModelTemplates).

You must then calibrate the .vst file to create a Vicon labeling skeleton (.vsk file) that is scaled for each specific subject of that type. You must do this the first time you intend to capture a new subject and each time you want to use a different marker arrangement on the same subject.

For detailed information about creating and using custom Vicon labeling skeleton templates, see Creating Labeling Skeleton Templates (VSTs).

To enable you to produce .vst and .vsk files, the Subject Preparation Tools pane contains the following sections:

• Subject Select a specific Vicon labeling skeleton template (.vst file) or Vicon labeleling skeleton (.vsk file). The contents of this list depends on the subject nodes enabled for capture (ie displayed with a check mark next to them) in the Subjects Resources pane.
• Subject Capture Enables you to capture a brief trial to obtain subject data. You can use the subject data to build or calibrate a Vicon labeling skeleton template and to manually label a subject.
• Subject Calibration Enables you to manage the subject calibration process to create a Vicon labeling skeleton (.vsk file) for a specific subject.
• Labeling Template Builder Enables you to build a generic Vicon labeling skeleton template (.vst file) for a type of subject (for example, humans, wearing a particular marker set). You subsequently use this .vst file to calibrate a Vicon labeling skeleton (.vsk file) for a specific subject of that type (for example, Jane, wearing the same particular marker set).
