Using Varjo Base

Varjo Base is the software used to control your headset. You can observe what the headset viewer is seeing, quickly access settings and presentation tools, and analyze your project with real-time data.

Overview of Varjo Base

The main window in Varjo Base is divided into different sections as shown in the image.

 

 

 

Hosting a session

The viewer’s experience is displayed prominently in the Headset view.

Below the headset view are tools to record your observations and guide the viewer when needed.

Gaze dot Visualizes the eye tracking feature to see where the viewer is looking. This feature is only accessible if eye tracking is calibrated.
Pointer Turns your mouse cursor into a VR pointer that is visible inside the headset.

 

Using presentation options

The Presentation tab in the Settings panel contains features to ensure that no headset actions are triggered accidentally by the viewer.

Disable headset buttons Disables the headset buttons, so that the viewer can focus on the immersive experience while the presenter controls headset features from Varjo Base.
Disable mouse in headset Disables the mouse in the headset, so the mouse works on your computer only and cannot be used to control System settings in the headset.
Disable notifications in headset Disables notifications in the headset to keep the immersive experience free of distractions.

Note that error messages are still displayed in the headset.

Positional tracking

Tracking lets your VR application know the exact position of your headset and allows you to move around while using the headset.

Note that this section applies to Varjo inside-out tracking and SteamVR™ Tracking only. If you are using a third-party tracking method, contact your tracking technology provider for more information.

 

Device statuses in Varjo Base

The tracking status of your headset is displayed in the status area in Varjo Base. If you use SteamVR™ Tracking, your base stations and optional controllers are also listed in the status area.

Override origin and direction

When using SteamVR™ Tracking, you can override the origin point, direction, and floor level of your room setup in Varjo Base. This can help you temporarily fix tracking-related problems, such as your application starting in the wrong direction or virtual content drifting out of place.

The override feature applies to your headset by default. Other trackables, such as controllers, are affected if your application supports the feature.

Note that this feature is intended to be a temporary fix only. We recommend you carefully check your tracking environment and perform a new room setup in SteamVR to correct problems related to tracking.

 

 

Follow the instructions to adjust your room setup:

  1.  Place your headset in the location where you want to start the scene and point it in the desired direction.
  2.  In Varjo Base, navigate to the System tab and select Override origin and direction. The Override button text will change to Active.
  3.  If needed, set the headset elevation in centimeters under Headset elevation from floor.

While the override setting is active, your application will use the adjusted room setup over the original one.

Return to your original room setup by clicking the Active button.
