Calibration and Camera Control
Section 5. Calibration and Camera Control
This section describes how to calibrate ARwall ARFX Scenepacks using the patented XR Sync system and describes how to use the ARwall camera controls once the ARFX Scenepack is up and running.
Section 5.1 XR Sync Calibration
This section describes how to calibrate ARwall ARFX using the patented XR Sync system.
Once the ARwall ARFX Scenepack scene is up and running, calibrate the scene so that the proportions and parallax look correct to the tracked physical camera. To perform calibration in ARwall ARFX Scenepack, do the following:
Press the TAB key on a keyboard or the X button on an Xbox controller, the calibration screen will open. Locate the center of the screen marked by the red crosshairs.
The green triangle/square that appears represents the calibration tracker. The current position is always relative to the last calibration point but should always move in relationship to wherever you move the calibration puck.
Note
The green triangle/square should move when moving one of the trackers connected to the system. This is the tracker previously set as the calibration tracker. If this is not the intended tracker for calibration, either swap the trackers physical positions (on the camera vs next to the screen).
Place the calibration puck flat against the screen and centered on the crosshairs with the green light on the tracker facing up (for 2.0 Trackers) and with the green light on the tracker facing down (for 3.0 Trackers). Both 2.0 and 3.0 Trackers will have the cable pointed up for correct calibration. Press the Calibration button (that was set previously under Hotkeys, by default it should be the C key on keyboard and B button on Xbox controller) while the calibration puck is on the crosshairs, then press TAB (or whichever button was previously set under Hotkeys) to exit the calibration screen.
2.0 Trackers
3.0 Trackers
Note
Feel free to press the Calibration button again if it does not look like it calibrated correctly the first time. Make sure the calibration tracker is positioned in place on the red crosshairs, until it looks like the ARFX Screen looks correctly positioned and does not jump around a lot between calibration button presses. This ensures that you have the most optimal calibration.
It is good practice to recalibrate anytime a lighthouse is moved or bumped, even if very minute. This could cause jitter/jumping of the virtual camera if not recalibrated.
Section 5.2 Camera Control
This section describes how to use the ARwall camera controls for both keyboard and Xbox controller once your scene is launched and calibrated.
Launch your ARFX scene and calibrate. Refer to the Installing ARwall ARFX Scenepacks section and XR Sync Calibration section above for more details.
Move the Hero Tracker (tracker on the physical camera) within the designated play area as dictated by the base stations. The scene should show the correct parallax.
Note
Here is how to tell if you are seeing the correct parallax after calibration:
Move the physical camera left, you should see more of the right side of the virtual scene environment.
Move the physical camera right, you should see more of the left side of the virtual scene environment.
Move the physical camera up, you should see more of the bottom of the virtual scene environment.
Move the physical camera down, you should see more of the top of the virtual scene environment.
Move the physical camera closer to the screen, you should see more of the virtual scene environment.
Move further from the screen, you should see less of the environment.
If this is not what you’re seeing, try to calibrate again and make sure that the base stations can clearly see each other and the trackers. Refer to the Base Station Placement section for more details.
The default virtual camera controls are described in Table 4 below.
Table 4: Camera ControlsAction
Keyboard
Xbox Controller
To move the virtual camera
Use the WASD navigation controls:
W = Forward
S = Backwards
A = Left
D = Right
Left Stick is the Forward, Backwards, Left, and Right control.
To move the virtual camera up or down
Use the following controls:
Q = Down
E = Up
Left Trigger is to move vertically down
Right Trigger is to move vertically up
To rotate/pan the virtual camera left or right
Use the following controls:
Use the left arrow (←) to pan the camera left.
Use the right arrow (→) to pan the camera right.
Right Stick pans the camera
LB (Left shoulder button) rotates 90 degrees leftRB (Right shoulder button) rotates 90 degrees right
To toggle the calibration menu
Use the Tab key:
Press Tab to toggle on/off
X button to toggle on/off
To calibrate the screen (while holding up the calibration puck to the center of the screen crosshairs, so the parallax and camera tracking look correct)

Press C while calibration puck is held in the center of the screen
B button while calibration puck is held in the center of the screen
To toggle focus method
Use the F key:
Press F to toggle on/off the focus method
A button or press down the Right Stick button to toggle on/off the focus method
To toggle focal distance input (also adds focal plane)
Use the P key:

To toggle camera debug info
Use the Z key:
Press Z to toggle on the camera debugging, positional data, rotation data, and FPS
Press the Z key again to remove positional and rotational data, but keeping FPS
Press the Z key again to toggle off camera debugging
Press the View button (looks like 2 rectangles) to toggle on/off camera debug info
To change bookmark or preset camera angle
Use the minus (-) or equal (=) keys:
Press the + key to fly to the next bookmark
Press the – key to fly to the previous bookmark
While in normal mode:
Press D-PAD Right arrow to fly to the next bookmark
To toggle snap mode of the virtual camera
(This forces the virtual camera to snap towards a direction on the virtual environment.)
Use the T key:
Press T to toggle between snap mode and normal mode.
