Virtuix Omni Operator Manual | Version 2.4| 7/25/2017
Module 1. Hardware Setup
1.1. Omni Hardware Setup
For a complete Omni installation manual, please refer to the Omni Owner’s Manual.
Omni Cable Routing: Place the cable chokes of the power and USB cables behind the cable clip
inside the PCB control panel per the image below to avoid unplugging of the cables during use.
Multiple Omnis: Connect multiple Omni PCs via a Local Area Network (LAN) for multiplayer
gameplay.
•Connect your PCs via an Ethernet cable and a powered LAN router (even when using only
two PCs, a router may be required).
•You may need to disable your firewall In Windows (go to Settings > Network & Internet >
Windows Firewall -> Turn off Windows Firewall for both private and public networks).
•Use only one pair of Vive base stations (Lighthouse tracking stations) per setup
(more than one pair of base stations will result in interference). One pair of base
station can track up to 5 Vive HMDs and hand controllers.
1.2. Lighthouse Base Station Setup
Lighthouse Positioning: Verify the following key factors when positioning and installing the
Lighthouse base stations:

2
Virtuix Omni Operator Manual | Version 2.4| 7/25/2017
•Avoid interference from a second pair of Lighthouse sensors in the vicinity.
•Avoid reflective materials like mirrors, shiny floors, or shiny wall objects around the Omni.
•Avoid excessive sunlight.
•Mount the base stations as high as possible (the higher, the better) and point them towards
the floor at a 60-degree angle.
Lighthouse Wired Connection: For improved tracking and less interference, connect the two
Vive base stations via the included syncing cable (A/B connection).
1.3. Vive HMD Setup
HMD Cable Routing: For a better user experience, route the HMD cable via the top cable strap,
not the back cable strap:
Vive Deluxe Audio Strap: We recommend purchasing the Vive Deluxe Audio Strap with
integrated headphones that make cable management easier and provide a much better user
experience than regular headphones.

3
Virtuix Omni Operator Manual | Version 2.4| 7/25/2017
HMD Cable Mounting: If using our VR Boom or cable retractor mechanism, provide for the
optimal cable “slack” by attaching the cable to the retractor and to the VR Boom as follows:
Vive VR Covers: We recommend purchasing Vive VR Covers that make the Vive easy to clean
between play sessions. The material on this VR cover can be wiped with antibacterial wipes after
each customer and dries quickly for the next customer.
1.4. Other Hardware Setup
PC Requirements: Ensure that your PC meets our minimum requirements:
•Processor: Intel™ Core™ i5-6600K @ 3.5 GHz equivalent or better
•Graphics card: NVIDIA GeForce™ GTX 1070 equivalent or better
•RAM: 8 GB RAM or more
No Background Processes: Verify that all Windows background processes and unnecessary
programs are shut down: Windows Auto Updates, Virus Scanners, and any other programs not
needed to run the Omni.
TV Connection: Omni Arena and other games based on Unreal Engine 4 may not be displayed
correctly on a TV screen if this TV screen is connected to the PC via DVI or a Display port. We
recommend connecting each TV via HDMI, and if needed connect the HMD via an HDMI-to-DVI
converter to the DVI port of the PC.
Audio: In addition to headphones, we recommend using speakers to project audio to the
audience watching the Omni player. Audio is crucial to attract customers and entertain the
audience. If you need help, please contact us for step-by-step instructions on how to get audio
channeled both through your speakers and headphones simultaneously.
Cleaning Cloth: Have a cleaning cloth by each Omni to clean the Omni Base prior to each use.

Module 2. Software Setup
2.1. HTC Vive Setup
Room Setup: Run HTC Vive room setup by choosing the “Standing” option and setting the
correct height parameters.
Disable Vive Menu Button: The Vive hand controllers have a menu button at the bottom that is
often pressed accidentally by players during gameplay, prompting a menu screen to come up
inadvertently in the game. This is highly disruptive of gameplay and results in confusion and
communication challenges. Disable the Vive menu button as follows:
Enter the SteamVR Settings -> Developer and uncheck the checkbox “Enable VR Dashboard”

5
Virtuix Omni Operator Manual | Version 2.4| 7/25/2017
Disable SteamVR Home Beta: The SteamVR Home functionality may interfere at times with the
Omni software and Omniverse system. We recommend you uncheck the SteamVR Home Beta
checkbox under SteamVR Settings -> General.
Video: Watch our video on how to best set up the Vive: https://youtu.be/cQKUgjrlWx8.
2.2. Omni Connect Setup
Download Omni Connect: Download and install Omni Connect, and download and read our
Omni Connect Quick Start Guide from www.virtuix.com/download.
Omni Connect Profile: Feel free to create a local profile instead of an Omni Online profile (Omni
Online requires an internet connection and is intended for consumer-use).
Pod Connection: Link the Tracking Pods to their designated PC before use via the included USB
cables to sync them to a designated Omni (they will not work otherwise). In a multi-Omni setup,
mark each Pod with a numbered sticker to indicate to which Omni they are linked, and number
each Omni accordingly.
Pod LED: Yellow vs. Green: To emit a wireless radio signal, the Pod needs to be inserted
properly into the shoe cradle. As long as the Pod is active but not emitting a wireless signal, the
Pod will show a blinking yellow light. Be sure to plug the Pod fittingly into the cradle to activate

6
Virtuix Omni Operator Manual | Version 2.4| 7/25/2017
the wireless radio signal, at which time the Pod will show a blinking green light (indicating
proper functioning of the Pod).
Channel Setting: In a multi-Omni setup, set different radio channels for each Omni (see guide).
Forward Only Mode: To accommodate bigger users, use the “Forward Only” functionality in the
Advanced menu (see guide).
Omni Controller Modes: Always leave your Omnis in Gamepad Mode to ensure they work with
Virtuix games (Keyboard mode is intended for home users who want to experiment with legacy
games).
2.3. Omni Game Setup
Navigation Modes: Get familiar and experiment with Coupled (walking direction is fixed to
looking direction), De-Coupled (walking direction is independent from looking direction),
and Soft-Coupled (combination of coupled and de-coupled) modes in our various games.
Coupled Mode: Select and recommend the Coupled navigation mode for novice players,
as this results in the easiest gameplay experience.
Calibration: For De-coupled and Soft-coupled modes (advanced players only), players need to
properly calibrate following the calibration procedures in our various Virtuix games. Ensure the
player is standing still and facing forward while calibrating. Improper calibration will result in a
bad player experience and even motion sickness.
Omni Arena Tutorials: Always place new players in the Tutorial levels first in Omni Arena (Core
Defense and Hard Point).
Omni Arena Multiplayer: For multiplayer gameplay:
•Connect all PCs via a Local Area Network (LAN); see instructions in Section 1.1.
•Designate one PC as the “host” of the multiplayer session by choosing “Create Match” in
the game’s main menu.
•On all other PCs, select “Find Match” to find the host’s game, then double click on the
match name to join the game.
•When a single customer wants to play Omni Arena, try to match him with a second
player for a multiplayer session or have a staff member act as second player on a second
Omni (multiplayer gameplay is more exciting and fun than single-player gameplay)
TRAVR: Training Ops: Use the leaderboards in Training Ops to organize leagues and
tournaments. You can give leaderboards a custom name suitable to your location or event.

Module 3. Omni Operations
3.1. New User Training
Training New Players: Training new players properly on how to walk on the Omni before they
enter VR with the Omni is crucial to a good experience. Giving the proper verbal instructions has
a major impact on a novice user’s ability to walk properly on the Omni, which determines the
quality and fun of his or her Omni experience.
•Watch our “Novice User Training” video here: https://youtu.be/J0K18Fxxqz4.
•Watch a video on how to walk on the Omni here: https://youtu.be/yNuSIh79ETU.
Training Procedure: Through years of experience of getting new players in and out of the Omni,
we have developed a highly effective procedure and script to teach new players how to walk on
the Omni. Practice and memorize this training script for novice players (see Appendix A) and pay
extra attention to the following important steps:
Clean the Omni Base before each use with a cloth.
Have the Harness back straps loosened before a new player enters the Omni.
Adjust the Ring height so that the Harness is positioned slightly above the player’s waist.
Feed the leg straps to the player through his legs.
Once the player is strapped in, pull the back straps for good support.
Stand next to the player, not in front of the player, to demonstrate the walking movement.
Have the player “Hold onto the ring with both hands” before taking first steps.
Show and tell the player to “Take one step forward and put your weight on your forward
foot. Let it slide back by gravity. Be sure to lean forward into your step.”
Hold the metal Harness frame with your hand and push the frame forward while asking the
player to keep walking forward.
At this stage, most players will be leaning forward excessively. Ask the player to “Now look
up and keep walking”, which will help straighten the player’s back.
Pull the back straps one more time for extra support.
Give the player the gun or controllers to practice walking without holding the Ring.
For average users: only focus on forward walking; do not teach backwards walking and
strafing.
For skilled users: explain backwards walking and strafing; explain how the Harness needs to
be in the back of the Ring to recognize backwards and strafing movement.
Ensure the player is not shuffling his feet, leaning backwards (not putting his body weight on
his forward foot), or leaning excessively forward.
Continue to train the player until he is able to walk on the Omni properly and comfortably;
do not stop the training prematurely.

8
Virtuix Omni Operator Manual | Version 2.4| 7/25/2017
Training Script: Provide staff members with a physical copy of the training script (see Appendix
A) and ask them to rehearse this training script.
3.2. Cleaning The Base
Cleaning The Base: Keep the Omni Base clean (free of dust and particles) at all times to ensure
smooth movement. Clean the Omni Base with a dry or damp towel before each gameplay
session. In case of dirt build-up, a deep-clean with water + soap and a rough cleaning sponge is
recommended.
No Wet Wipes: Wet wipes should never be used to clean the Omni Base, as they leave behind a
residue that increases the Base friction. Just use water or a combination of water and soap.
No Petroleum Based Products: No petroleum based products should ever be used to clean the
Base. Water/soap is preferred; silicon spray can be used to restore the Base’s slipperiness in
case of high-friction build-up.
3.3. Best Practices
Clean HMD Lenses: Use a lens cleaning cloth to clean the HMD lenses before each use.
Additionally, the use of Vive HMD covers are a necessity for hygiene reasons.
IPD: The Vive has a turning knob at the bottom right to adjust the distance between the lenses;
the average is a distance of 65mm for a comfortable experience. Be sure to verify the HMD’s IPD
setting before each gameplay session, and adjust this setting back to the average of 65mm in
case players have changed this setting during their session. Suggest to players to adjust the IPD
for their eyes specifically when they have put on the headset by turning the knob on the bottom
right side of headset.

9
Virtuix Omni Operator Manual | Version 2.4| 7/25/2017
Attract Crowds: Have staff walk and run on the Omni during downtimes to attract crowds, and
use audio and visuals to attract players. Hire staff members that are energetic and athletic, love
VR gaming, and love the Omni.
3.4. Safety
Please always adhere to the following safety instructions:
Do not allow any players on the Omni who are pregnant, intoxicated, epileptic, or recovering
from major surgery, illness, or heart attack.
Do not allow any players on the Omni who are taller than 6’5” (195cm) or weigh more than 285
lbs (130 kg).
Instruct players to hold onto the Ring with both hands when entering and exiting the Omni.
Do not allow players to wear the Omni footwear outside of the Virtuix Omni; take off the
player’s Omni footwear as soon as he has exited the Omni.
Please refer to the Omni Owner’s Manual for a complete list of usage instructions and safety
warnings. Failure to follow all usage instructions can result in injuries.

10
Virtuix Omni Operator Manual | Version 2.4| 7/25/2017
Module 4. Troubleshooting and FAQ
The player is moving on the Omni but his movement is not being recognized in the game.
What should I do?
1. Verify that the Pods are inserted in the shoe cradles and are turned on (green light blinking).
Note: the Pods needs to be in the shoe cradles to submit a wireless signal and be detected.
2. If a yellow LED is blinking on the Pod, unplug the Pod from the shoe cradle and plug it back in.
3. If Step 2 did not solve the issue, turn the Pods off and back on.
4. If Steps 2 and 3 did not solve the issue, connect the Pods to the PC via the provided USB cables.
After the connected Pods have been recognized in Omni Connect, disconnect the Pods.
One of the Pods is showing a blinking yellow LED. What should I do?
The yellow LED blinks if the Pod is active but not submitting a wireless signal. The Pod needs to be
inserted in the shoe cradle to submit a radio signal. If your Pod is blinking yellow in the shoe cradle,
unplug the Pod from the cradle and plug it back in so that a blinking green light appears. If the green
light does not appear, turn the Pod off and back on.
The Omni Pods continuously connect/disconnect instead of staying connected. The player’s
walking is stuttering or unresponsive. What should I do?
Change the “Omni Selection” number on the Tools->Advanced screen. This selection changes the
Radio Frequency (“RF”) channels on which the Omni communicates. You may be experiencing RF
interference because of other devices in the area.
The player is walking forward in the Omni, but his character is walking backward. What
should I do?
If the Harness is pushed to the back of the Ring, foot movement will result in backward motion or
strafing. Ensure that the player is not inadvertently pushing the Harness back in the Ring while trying
to walk forward.
To accommodate bigger users, select the “Forward Only” mode in the Advanced Window of Omni
Connect. “Forward Only” mode disables strafing and backward movements, and translates all
movements of the player to “Forward”.
Also make sure the Ring cable is connected between the Ring and the left Tower and reset the
game.

11
Virtuix Omni Operator Manual | Version 2.4| 7/25/2017
The player is playing an Omni game but his speed is not analog. What should I do?
Check that Omni Connect is in Gamepad mode. If it is in Keyboard mode, you may lose analog
speed.
The player is playing an Omni game with De-Coupled movement, but he’s heading in a
direction that is offset from his physical walking direction. What do I do?
The player’s calibration for de-coupled mode is off. Have the player re-calibrate by following the
calibration procedure of the game (the player will likely be prompted to press a button while looking
straight ahead. If you do not see this prompt, try restarting the game and selecting ‘De-Coupled’
from the game options again).
The game is not showing the Vive hand controllers / gun controllers. What should I do?
1. Verify that the player is not covering the sensors with his hands (if so, instruct him not to).
2. Verify that the hand controllers are turned on and charged.
3. Turn the hand controllers off and back on.
4. If Steps 1 and 2 did not solve the issue, re-sync the hand controllers via the sync function in
Steam VR.
The headset is not being tracked properly in the game. What do I do?
1. Verify that the headset is turned on. Plug the headset cable in and out of the control box.
2. If Step 1 did not solve the issue, re-do the room setup process in Steam VR
The player is blocking the HMD or hand controllers’ sensors with his hands, causing visible
tracking loss of head/hands. What should I do?
Advise the player not to cover the HMD or controllers as it affects the tracking, and offer to help
them tighten the HMD if it is loose.
The player height in the game is off (either too close to the floor or too high). What do I do?
Re-do the room setup process in Steam VR (select the “standing only” option and fill in the correct
height measurements).

Virtuix Omni Operator Manual | Version 2.4| 7/25/2017
APPENDIX A.
NEW USER TRAINING SCRIPT
1. Place the correct size of Omni Harness inside and resting on top of the Support Ring,
orientated so that the User can step into it once you have opened the hatch.
2. Be sure the Back Straps are entirely loosened. This is important to avoid that you need
to start fiddling with the straps in the user’s back after he is already inside the harness
(*awkward*).
3. Open the hatch, and have the User step carefully onto the Omni platform and into the
Omni Harness with both hands on the Support Ring, one foot at a time.
4. With at least one hand on the Ring at all times, have the User turn around 180 degrees
so that he/she is facing the instructor and the open hatch, and then close it –ensuring it
is properly locked into place.
5. The Omni Harness should be positioned slightly above the User’s waist when resting on
the Ring. If necessary, adjust the height of the Support Ring.
6. Fasten the Velcro belt around the User’s waist, ensuring it fits snugly.
7. Push each of the thigh straps from behind through the User’s legs, one at a time, so that
the User can grab each thigh strap and click it into the thigh buckle. Say “this is for the
left leg”, “this is for the right leg” as you do this. Explain how to tighten the thigh straps
–“Pull the green tabs out to the side, but they don’t have to be too tight”.
8. Tighten all other straps so they are comfortable but secure. Especially tighten the two
straps in the back of the User, as they will provide maximum support.
9. First Steps Training: Instructor positions himself to the side of the User while facing the
same direction as the User.
a. Do not face the User, but stand next to the User while demonstrating.
b. The instructor’s positioning is to ensure the User can properly see and understand
each movement as the instructor explains and demonstrates how to use the
Omni (as opposed to a mirrored view).
10. Hold the metal frame of the Harness firmly in one hand and push the Harness and
User forward inside the Ring. Keep the User pushed forward against the Ring
throughout the training exercise.
11. Instruct the User to place his front foot near the outer edge of the Omni while putting
his weight on that forward foot.

13
Virtuix Omni Operator Manual | Version 2.4| 7/25/2017
a. “Take one step forward and put your weight on your forward foot, and let it slide
back via gravity.” Encourage the User to take a full step and lean forward on their
forward foot.
b. “Lean forward / shift your weight forward and lean into your gait, placing your
weight on your forward foot.”
c. The User can keep both hands on the Ring during this initial training phase.
d. Instructor needs to physically demonstrate the actions instructed.
e. After the first step the User will proceed to do the same with the other foot.
f. Make sure the User is not shuffling his feet but taking actual steps.
g. The instructor can make the analogy with a bike: “Feels a bit awkward at first, but
after a few minutes the movement will become second nature. It’s a matter of
finding the right balance and getting used to the movement.”
12. Next instruct the User to walk forward normally at a slow and steady pace.
a. Continue to hold the metal frame of the Harness and continue to push the
Harness and User forward against the Ring.
b. If the User has trouble, make sure to mirror the User (standing by his side) and
show him to shift his weight forward / lean forward and put his weight on his
forward foot. Both hands can be on the Ring for extra support.
c. Make sure the User does not attempt to run or let go of the Ring if he needs more
time to practice.
d. After these initial steps, tighten the two straps in the back of the User once
more for maximum support.
e. The User should continue to walk for another 1-2 minutes to get a proper feel for
the Omni.
13. Ask the User to “look up while walking forward” (instead of downwards at his/her
feet). This will automatically straighten the User’s posture.
14. Next the User should be given the controller.
a. Have the User walk for 2-3 minutes while holding the controller.
b. Explain the controller layout (Triggers and Buttons).
15. Do not allow anyone to put on the HMD until he is fully accustomed to walking
comfortably on the Omni. Continue the training as long as necessary.
16. Once the instructor deems the User is ready for Omni VR, give the User the HMD to
start the VR experience.
a. Be sure to hold the controller for the User while he is putting on the HMD, then
hand the controller back to the User.
b. Tighten the two back straps one more time before gameplay.

14
Virtuix Omni Operator Manual | Version 2.4| 7/25/2017
17. During gameplay, ensure the HMD cable is out of the User’s way. Do not let the cable
wrap around his face or neck.
Do the following after each gameplay session:
1. Once play has ended, take the User’s hand controllers and HMD. To ensure the User
exits the Omni safely, adhere to these steps:
a. Ask the User to unclip the buckles on the thigh straps
b. Unfasten the Velcro belt and undo the belt strap.
c. Open the door and ensure the User holds onto the Ring while exiting (but not
onto the Ring door). Ensure the User does not put his weight onto the Ring door
or put his hand between the door and the Ring.
d. Tell the User to step onto the Deck first, and then carefully step off the Omni.
e. Do not let the Harness come out of the Ring.
f. As soon as the User has dismounted, remove the Pods from his Shoes.
g. Do not let the User walk away from the Omni while wearing the Shoes.
2. Prepare the station for the next user:
a. Uncoil the HMD cable and clean / replace the HMD face covering.
b. Check that the HMD is set to an IPD of 65.0mm, in case the user adjusted it (use
the turning knob at the bottom right of the Vive HMD).
c. Wipe down the Base (do not use wet wipes).
d. Loosen the Harness back straps.
