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.

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 SteamVR™ Tracking and Varjo inside-out tracking (Beta) only. Contact your tracking technology provider for more information if you are using another tracking method.


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 listed as well.

Room setup is performed when you set up SteamVR™ Tracking for your headset. You can start a new room setup at any time as follows:

  1.  Navigate to the System tab in Varjo Base.
  2.  Make sure that SteamVR™ is selected under Headset tracking.
  3.  Start SteamVR room setup.

Read more about preparing your environment.


Calibrating Varjo inside-out tracking (Beta)


Varjo inside-out tracking (Beta) uses the front-facing cameras on XR-3 to continuously scan the room and keep track of your position while you are using the headset.

Tracking is calibrated when you set up Varjo inside-out tracking (Beta) and a new calibration is started automatically whenever you use the headset in a new environment. The headset can remember where it was last used and no calibration is needed in the same environment.

You can manually start a new calibration at any time as follows:

  1. Navigate to the System tab in Varjo Base.
  2. Under Headset tracking, make sure that Varjo inside-out tracking (Beta) is selected.
  3. Start Varjo inside-out tracking (Beta) calibration.

Override origin and direction

SteamVR™ Tracking

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.


Forward direction and origin

Varjo inside-out tracking (Beta)

When using Varjo inside-out tracking (Beta), you can quickly adjust the forward direction, origin point, and floor level of your tracking environment. This is useful if, for example, you want an application to start in another direction.


You can adjust the tracking setup as follows:

  1.  In Varjo Base, navigate to the System tab and select Forward direction and origin. Alternatively, open the Menu and select the shortcut for Forward direction and origin.
  2.  Move to the location you want to set as the origin point of your tracking environment.
  3.  Face the direction you want the content to appear from.
  4.  If needed, press the up and down arrow keys on your keyboard to align the virtual grid with the floor level. Push Reset with your finger if you want to return the grid to its original level.
  5.  When ready, push Confirm with your finger.
