You can use the mouse to manipulate items and manage the way data is visualized in Nexus, and you can combine standard mouse actions with keyboard keys. The following mouse and keyboard combinations are used most frequently in Nexus.
Navigate in the 3D Perspective view:
| Tip |
To open files in Nexus, in addition to loading files as described in Play back data with the time bar, you can drag and drop Nexus files onto a 3D Perspective view (or any other view). File types that you can load in this way include: C3D, ENF, VSK/VST, X1D, X2D, and XCP.
Select objects in the view pane:
Display/hide a section within a pane:
For lists summarizing more Nexus shortcuts and mouse actions, see Hot keys and shortcuts.
For more information on getting to know the Nexus user interface, see:
The Data Management tab of the Communications window enables you to create a hierarchical structure in which to store and manage all the data associated with your motion capture trials. For information on how to do this, see Prepare a data storage location.
| Tip |
To toggle the display of the Data Management tab, press F2.
It also enables you to:
To manage Nexus system connection and real-time data-streaming, click the system connection buttons at the top of the Resources pane:
At the top of the Resources pane, click the tab for the resources you want to manage:
In the System Resources tree or Subjects Resources tree, select the item(s) you want to configure.
Depending on whether you are in Live mode, you can then:
For more information, see Set properties in Vicon Nexus.
You can configure certain aspects of the Nexus system, such as system components and motion capture subjects, by configuring settings in the corresponding Properties section of the user interface.
Required properties for which you must specify a value are indicated in the Nexus user interface with a shaded background.
Some properties settings automatically persist, so Nexus remembers them in subsequent sessions. You must explicitly save other settings using the relevant configuration management controls for that area of the Nexus window.
To set properties in Nexus:
For more information on configuration files, see Manage configurations in Vicon Nexus.
At the left of the View pane toolbar, click the drop-down list and select one of the available views:
At the right of the View pane toolbar, click the buttons to specify the number and arrangement of views displayed:
Depending on the view selected, additional lists and buttons are available to manage the display options.
| Tip |
To display multiple Camera views, in the System Resources tree, SHIFT+click to select multiple cameras and in the View workspace, select Camera view.
At the top of the Tools pane, click the buttons for tools relating to the stage in the workflow that you want to display. The buttons are displayed in the order of a typical Nexus workflow (from left to right) and are enabled appropriately, depending on whether you are in Live or Offline mode (the following image is in Live mode).
To find out more about the motion capture workflow, see Vicon Nexus motion capture workflow.
To explore the time bar:
| Tip |
In addition to using the time bar to view and navigate trials, you can also use it to:
• View data quality as a heat map. For more information, see Review trial data using the time bar.
• Create and manage events (for example, a foot striking a force plate, or a joint attaining a specified angle, etc). For more information, see Add events to trials.
The Nexus menu bar enables you to access common commands.
Access frequently used commands from the Nexus motion capture workflow from the Nexus toolbar.
The Nexus toolbar contains buttons that enable you to save the current trial, close the current trial, and undo and redo actions. In addition it contains the following controls:
Clicking a button on the toolbar executes the defined action for the button. A button is dimmed if it is not available, for example, if it cannot be run at that stage of the workflow or if a customized button has been deleted or renamed.
| Tip |
To display a tooltip that explains why a button is unavailable, hover the mouse pointer over the button.
You can determine how Nexus looks and behaves by creating and editing configurations in the configuration management controls in the Nexus window. To view and select any default configurations that were installed with Nexus, click the dropdown list in the relevant configuration management controls, for example, for View Types:
You can create different configurations to suit different types of motion capture applications and then select the appropriate configuration when required. You can also save configurations for use by multiple users (Shared) or for a specific user (Private), to suit your organization:
The default Nexus toolbar is stored in the Standard.toolbar configuration file in the Shared Nexus configuration folder Toolbars. If you add, delete, or reposition buttons on the Nexus toolbar using the Customize Toolbar dialog box, these customizations are stored in your Private configuration folder.
To manage configurations in Nexus:
|Nexus UI area||Configuration type||Configurations folder\file|
|Capture Tools pane||Motion capture settings||TrialTypes\*.TrialTypes|
|Biomechanics Workflow area of Communications pane||Biomechanics workflow||CaptureWorkflows\*.CaptureWorkflow|
|Sounds dialog box||Sounds settings||AudioSchemes\*.AudioScheme|
|Monitors tab in Communications pane||Event monitors and actions||Monitors\*.Monitors|

When pipelines, view types, monitors, labeling skeleton templates, and configurations are displayed in Nexus (ie, listed in menus, etc), you can immediately recognize whether they are Private, Shared, or System files:
|Shared||Can be viewed by multiple users; can be changed only by the user who was logged on when the file was first created and saved. Shared files are stored in subfolders in:|
|Private||Can be viewed and changed only by the user who was logged on when the file was first created and saved. Private files are stored in subfolders in:|
|System||Cannot be changed (Read-Only) and are upgraded when the next version of Nexus is installed. Stored in subfolders in the Nexus installation folder, whose default location is:|
C:\Program Files (x86)\Vicon)\Nexus2.# or
In addition to the usual resize and close window options, you can slide the Resources and Tools panes to either side of the Vicon Nexus window and or minimize the Communications pane, to give you a larger workspace area.
|To hide the Resources and/or Tools panes||At the top of the Resources or Tools pane, click the UnPin button.|
|To hide the Communications pane||Double-click a tab within the Communications pane; or|
To hide the pane whenever you load a trial, on the Window menu, select the Close Communications Pane on Trial Load option.
|To reveal the Resources and/or Tools panes||Click the text at the top of the tab at the side of the Nexus window.|
|To reveal the Communications pane||Double-click a tab within the Communications pane; or|
To make the pane visible whenever you load a trial, on the Window menu, clear the Close Communications Pane on Trial Load option.
|To return a pane to being locked into place||At the top of the pane, click the Pin button.|
|To undock (float) and dock a pane||At the top of the (pinned) pane, click the Undock or Dock button.|
The View pane cannot be undocked, repositioned, or resized in the Nexus window. However, you can open a separate floating view pane by selecting the New floating workspace command from the Window menu. This floating workspace can be repositioned and resized.
The width of the View pane is affected by resizing panes to the left and/or right of it. The height of the View pane is affected by resizing the panes below it.
