Calibration

When you connect OVR Nodes, it says “None” under each OVR Node icon. This information tells us that the OVR Node has not been assigned to any positions yet.

You should use the 3-stage dynamic calibration system for OVR Nodes to give more precise data and to assign any position. At first, you have to do all 3 stages of the calibration sequentially, but when you want to improve the experience or assign OVR Nodes from one position to another, you can start from the 2nd or directly from the 3rd stage.

Calibration for Locomotion

1. Calibrate Nodes: In this step, magnetometer calibrations of individual OVR Nodes are made.
2. Manage Node Positions: In this step, you assign positions to your OVR Nodes. The following are the configurations that apply to the position assignment:

   WalkOVR One	1 Chest/Knee
   WalkOVR Twins	1 Left Knee + 1 Right Knee
   WalkOVR Trio	1 Chest/Knee + 2 Knee/Ankle
   WalkOVR Mocap	1 Chest/Knee + 1 Left Knee + 1 Right Knee + 1 Left Ankle + 1 Right Ankle

   
3. Reset Posture: Before going through this step, your OVR nodes must be in the designated locations on your body. In this step, you are asked to put on the headset and stand upright for 3 seconds.

NOTE: If you think that the calibration is corrupted during the game, you can only reset posture instead of doing all the steps.

If decoupling is enabled, you need to turn on Steam VR before resetting posture. If the decoupling is disabled, you can turn on Steam VR after the entire calibration process is complete.

After the 3-step calibration process, your OVR Nodes are calibrated and now you can ready to play the game and enjoy using WalkOVR.

If you are using WalkOVR in Locomotion mode, when you open Steam VR you should see an OVR Node icon representing WalkOVR in Steam VR Status regardless of WalkOVR One/Twins/Trio/Mocap.

After the 3-step calibration process, Connection Status should look like the screenshot below.

Calibration for Mocap

1. Calibrate Nodes: In this step, magnetometer calibrations of individual OVR Nodes are made.
2. Manage Node Positions: In this step, you assign positions to your OVR Nodes. The following are the configuration that applies to the position assignment:

   WalkOVR Mocap

   1 Waist + 1 Left Knee + 1 Right Knee + 1 Left Ankle + 1 Right Ankle

   
3. Reset Posture: Before going through this step, your OVR nodes must be in the designated locations on your body. In this step, you are asked to put on the headset and stand upright for 3 seconds.

NOTE: If you think that the calibration is corrupted during the game, you can only reset posture instead of doing all the steps.

If you are using WalkOVR in Mocap mode, you need to turn on Steam VR before the reset posture. When you open Steam VR, you will initially see only the headset and controllers in Steam VR status.

After the reset posture, you should see an OVR Node icon representing each OVR Node in Steam VR Status, meaning a total of 5 OVR Node icons.

After the 3-step calibration process, your OVR Nodes are calibrated and now you can be ready to play the game and enjoy using WalkOVR.

After the calibration process is done successfully, the Connection Status should look like the screenshot below.

Calibration on OVRLay

OVRLay is a plugin to the OVR Portal desktop software that runs on the SteamVR interface. With this plugin, you can calibrate, and adjust motion profile and controls without taking out the headset.
