Use Your VR Equipment

To get the best and most immersive experience in High Fidelity, we encourage you to use VR equipment, such as the Oculus Rift or HTC Vive. With these HMD devices and hand controllers, you will be able to interact with people in 3D, track body movements, and engage with the objects around you. We support the following VR equipment:

Head Mounted Displays Hand Controllers
Oculus Rift (CV1 and S) Oculus Touch
HTC Vive HTC Vive
Windows MR XBox One Controller

Comfort Mode

Motion sickness is a real problem for many people when they put on a HMD and enter VR. This happens because your eyes experience movement in VR, while your body stands still. If you experience motion sickness and discomfort using VR equipment, you are not alone.

“Comfort mode” is designed to decrease the effects of motion sickness while using High Fidelity. This mode:

  • Disables sharp turns
  • Decreases your field of vision by darkening the edges of the screen
  • Adds a ground plane and grid

All of these features were developed to help you orient yourself when moving around in VR.

To enable comfort mode, go to Menu > Settings > Controls on your tablet. Use the slider to adjust how much of the environment you see in VR.

Change How You Move in VR

You can change many avatar movement settings in VR such as jumping, flying, and leaning behavior. To do so:

  • In Desktop mode, go to Settings > Controls in the menu bar.
  • In VR mode, open your Tablet and go to Menu > Settings > Controls.
Setting Description
VR Movement > Teleporting Enables teleport controls to move seamlessly between positions within a domain.
VR Movement > Walking Enables walking controls to move within a domain.
VR Movement > Strafing Enables strafing controls (to walk sideways).
VR Movement > Jumping and flying Enables jump and fly controls.
VR Movement > Movement Direction

This setting controls which direction you move in:

  • HMD-Relative: Move in the direction your head is pointing.
  • Hand-Relative: Move in the direction your dominant hand is pointing.
  • Hand-Relative (Leveled): Move in the direction your hand is pointing, without taking pitch into account.
VR Movement > Dominant Hand Select ‘Left’ or ‘Right’. Teleport and turn controls move to the controller in the dominant hand.
VR Movement > Rotation Mode

This setting controls how you turn in VR:

  • Snap turn: Rotate your avatar sharply to the left or the right.
  • Smooth turn: Rotate your avatar smoothly as you turn to the left or right.
  • Comfort mode: Enable comfort mode and decrease the field of vision while moving in VR mode.
VR Movement > Control Scheme Selection

This setting determines how you control your walking speed:

  • Default: Your walking speed will remain the same, no matter how far forward you push your controller’s joystick. Fully pushing the joystick forward will make your avatar run.
  • Analog: Your walking speed changes based on how far forward you push your controller’s joystick. Fully pushing your joystick forward will make your avatar run.
  • Analog++: Your walking speed changes based on how far forward you push your controller’s joystick. You can use the slider to change the maximum walking speed in meters/second. Fully pushing your joystick forward will make your avatar run.
VR Movement > Avatar leaning behavior

This setting controls if and when your avatar leans in VR mode.

  • Auto: This is the default setting. Your avatar will lean if you are standing in the real world.
  • Seated: Your avatar will not lean if you are sitting in the real world.
  • Standing: Your avatar will lean if you are sitting in the real world.
  • Disabled: Your avatar can sit on the floor (experimental).
User real world height (in meters) You can change your real world height for better tracking in VR mode.

Motion Capture Using Vive Trackers

You can enhance your High Fidelity experience using full body motion capture (mocap). High Fidelity currently supports mocap using HTC Vive Trackers.

Vive trackers need to be strapped to the body part you wish to track. You can replace the HMD and hand controllers with trackers if you only need to track the movement of your head and hands.

You can set up different mocap systems:

Mocap System Equipment Needed Recommended Straps
Head HMD or 1 Vive Tracker Head strap for Vive Tracker
Hands Hand controllers or 2 Vive Trackers Hand strap for Vive Tracker
Head + Hands + Feet 2 Vive Trackers + HMD + 2 Hand Controllers Foot straps
Head + Hands + Feet + Hips 3 Vive Trackers + HMD + 2 Hand Controllers Hip Strap: Drill a hole in the back of a thick leather belt and attach the tracker using a 1/4” screw.
Head + Hands + Feet + Hips + Chest 4 Vive Trackers + HMD + 2 Hand Controllers Chest straps
Head + Hands + Feet + Hips + Shoulders 5 Vive Trackers + HMD + 2 Hand Controllers Shoulder straps

Note

You can replace the HMD and hand controllers with trackers if you only need to track the movement of your head and hands.

Configure Your Mocap System

  1. Strap your Vive trackers to your body as shown in the image.

  2. Connect your trackers, HMD, and controllers to SteamVR.

  3. In Interface, pull up your HUD or Tablet and go to Menu > Settings > Calibration.

  4. Configure your mocap system by:

    • Selecting the right device for your head and hands. If you’re using a head tracker instead of an HMD, click ‘Use HTC Vive Devices in Desktop Mode’.
    • Selecting the body position of any additional trackers.
    ../../_images/vive-config.PNG
  5. Click ‘Apply and Calibrate’.

  6. Stand in a T-Pose until the timer counts down to zero:

    • Feet together
    • Arms out
    • Head looking straight ahead.
  7. Check to see that each tracker is tracking the corresponding joint on your avatar.

  8. You can also calibrate your trackers without using your tablet. Once you apply your configuration, stand in a T-Pose and hold the following four buttons together for 1 second: Left Trigger, Right Trigger, Left Menu Button, Right Menu Button. You can press the same buttons together for a second to remove your calibration from the trackers.

Note

When you setup your Vive, you choose which way to point the arrow as your reference. During calibration, it is important that you face the same direction. If you can not remember the arrow’s direction, press the Vive System Menu Button and look on the ground for a marker. This is important to make sure your joints are oriented correctly.

Troubleshooting

Issue Troubleshooting Steps
My calibration failed
  • Check if your trackers are properly connected in SteamVR.
  • Have you selected the correct configuration in your tablet and do you have enough number of trackers to support that configuration?
  • If you are performing and not in HMD, did you select to ‘Use HTC Vive in Desktop Mode’?
  • Are any of the trackers blinking? If so, they may need to be paired again.
  • Do you have the correct number of dongles plugged in to your computer? You will need one dongle per tracker. If you are performing with all 7, then you may need a USB hub to handle them.
My sensor is jiggling a lot Make sure the straps on the sensor are tightened.
My sensor keeps losing tracking
  • If it’s the hip tracker, is your shirt is tucked in and not covering the puck? Also make sure your headphone cord isn’t covering the puck.
  • Can the base stations clearly see the tracker?
  • Is the signal from the base station conflicting with another Vive setup nearby?
  • Are you clear of reflective surfaces nearby? (such as picture frames, whiteboards, shiny tables).
  • Is the lighting consistent across the room (minimal outdoor lighting)?
  • Try restarting SteamVR.

Note

Remember to charge your trackers when you aren’t using them so that you don’t have to deal with a low battery tracker negatively impacting your performance.

Gamepad

If your HMD does not come equipped with hand controllers, you can use a gamepad. However, High Fidelity is best experienced with VR equipment or the keyboard in Desktop mode.
