Collaborating For The First Time
Before you start collaborating in XR, some housekeeping tasks are required to ensure the experience runs smoothly for all those involved. This includes preparing your physical environment and setting up each of the XR collaboration tools that you plan on using. These steps will differ depending on the combination of devices and tool(s) you plan on using. In addition to helping you select the best XR tool to suit a variety of specific needs, the XRCollaboration.com website provides some product-specific information on how to go about this setup for different tools and devices, together with approximate estimates of how much time you should allow for those tasks.
Setting Up XR Ecosystem Accounts
The Oculus division of Facebook not only makes HMDs, but they also provide a software distribution platform for applications called the Oculus Store. The Oculus Store enables you to obtain rights to use preview and commercially released applications for Oculus Go, Oculus Quest, Oculus Right and GearVR HMDs.
To get started, you need to create an Oculus account. An Oculus account is required to use Oculus devices, apps and the Oculus store: https://support.oculus.com/259993457969289/
Note: When you create an Oculus account, you'll create an Oculus username that's publicly visible and shared on all your Oculus devices. You can change your username only once every 6 months. So, be mindful about the username that you choose. You can also create or link your Oculus account using Facebook: https://support.oculus.com/1775053542763938/
SteamVR is part of the Steam service by Valve. Steam is the largest digital distribution platform for PC gaming. SteamVR uses the OpenVR SDK to support headsets from multiple HMD manufacturers, including Valve, HTC, Windows Mixed Reality HMD device manufacturers.
Before you start using XR Collaboration tools made available through SteamVR, you'll need to create a Steam account here: https://store.steampowered.com/join/
Then download the SteamVR app: https://store.steampowered.com/about/
SteamVR is free to download, although you'll still need to pay for many of the applications. Here is a direct link to the VR applications available on SteamVR: https://store.steampowered.com/vr/
SteamVR is available on PC and Macintosh but you'll need to have a decently powerful computer to run it. See SteamVR's official store page for current requirements: https://store.steampowered.com/app/250820/SteamVR/
Preparing Your Physical Environment
Upgrade Your Network Connectivity
Whether you are using a video conferencing tool or a XR collaboration tool, you will want to ensure you have a stable and reliable Internet connection. A poor internet connection is likely to interfere with the experience, or even render it entirely useless.

Video Conferencing Tool Requirements
Even though the focus of this publication is on XR Collaboration, we know that some of you will be thinking about the requirements for video conferencing tools so we are providing that information too.
If you are using a video conferencing tool, you will need an internet connection – broadband wired or wireless (3G or 4G/LTE). Minimum bandwidth is 600kbps (up/down) and recommended is 1.5 Mbps (up/down). We generally recommend an average of an additional 60 to 150 kbps for VoIP traffic.
Optimum bandwidth for video conferencing:
- High Definition Video: 2.5 Mbps (Receive) and 3.0 Mbps (Send)
- High Quality Video: 1.0 Mbps (Receive) and 1.5 Mbps (Send)
- Standard Quality Video: 0.5 Mbps (Receive) and 0.5 Mbps (Send)
The actual bandwidth requirements and utilization will vary based on multiple factors, including:
- The make and model of the web camera used.
- The resolution setting of the camera.
- The frames per second (FPS) setting.
- How many cameras are activated in the meeting.
- How many active cameras are on the same network.
- The bandwidth utilization of other meeting activities, such as screen or desktop sharing, Voice over IP (VOIP), etc.
- Whether or not the PC in question is transmitting video, or only receiving.
Issues begin when there is interference within the network that could cause a delay in the transmission of data, which could come in the form of latency, jitter and packet loss:
Acceptable latency for video conferencing is less than 300 milliseconds round trip from one endpoint to another before a noticeable delay – between the speaker and the receipt of their words by the far end participants – is registered. The degree of acceptable latency is influenced by the type of the video conference. It is also desired to have less than 40 ms jitter and 1% or less packet loss.
XR Collaboration Tool Requirements
If you are using a XR Collaboration tool, you will need a good internet connection – broadband wired or wireless (4G/5G). Optimum bandwidth is 1.5 Mbps (up/down). We generally recommend an average of an additional 60 to 150 kbps for VoIP traffic.
Recommended bandwidth and latency for XR Collaboration:
Surprisingly, the bandwidth requirements for XR Collaboration tools are generally much lower than video conferencing tools! This is because most of the content is preloaded before you enter a collaboration “room” or session. A higher bandwidth will result in a faster “startup” time getting into a session. Once a session is started, bandwidth is primarily consumed by voice, annotation, movement tracking for other user avatars and content (2D, 3D) insertion and sharing. Of course, if you start sharing your computer screen into your XR Collaboration tool session, you will need the extra bandwidth for the video streams (see the “Video Conferencing Tool Requirements” section for details). Overall if you have 10Mbps down you should be able to handle anything.
What is more important than bandwidth for XR is the latency of your connection.
Planning a Standing Space
If you are using a VR device and plan to be standing and moving, you will typically need a clear rectangular space in the real world to move around in. Depending on the VR device you are using, you may need to set up tracking sensors (often referred to as “lighthouses”) which are used to track your physical movements and reflect those in the virtual environment. Newer devices often have those sensors built into the device itself, which makes this initial setup a much more straightforward process.
Typically, we recommend a safe area in excess of 3 feet by 3 feet (1 meter by 1 meter). However, some tools will work best with a minimum safe area of 5 feet by 5 feet (1.5 meters by 1.5 meters). The useful “guardian” feature of the Oculus Quest headset streamlines this process by giving users the ability to establish a safe area within any room, which the device will remember and recognize for the duration of the session.
Planning a Sitting Space
If you are going to be engaged in lengthy XR collaboration sessions or are unable to stand, it might be preferable to set up your device while sitting down. In such cases, it is recommended to use a seat which can swivel to reduce the amount of strain when looking around at different areas of your XR environment.
While some devices, such as the HoloLens, are designed to let users wear spectacles underneath the visor, some HMDs are not compatible with prescription glasses or at least don’t allow for room to wear them comfortably. Should you not want to switch to wearing contact lenses when using XR, it is possible to order prescription inserts for various devices such as the Magic Leap 1 or Nreal Light. These usually cost in the range of US $100-250 each but some device makers are offering developer kits with several lenses.
The quality of your voice and the reduction or removal of background noise is very important in your XR Collaboration experience. We recommend that you select a good noise-cancelling, unidirectional microphone and if you will wear it, it should be something that feels comfortable over long periods of time. Some people prefer boom or desktop stand microphones.
Preparing Your XR Environment
Picking a Username
Since you are likely to be using XR collaboration tools in a professional setting, it is a good idea to ensure you select a username for your XR tool that makes you readily identifiable (your first name + last name initial is usually a good approach). See the section titled “Setting Up Your XR Ecosystem” for more details.
Design an avatar that is easily identifiable as you by others. Look at using your own personal face image and/or customize your clothing style where such options are available. Some tools have more sophisticated avatar personalization options than others, so (as per above) you should allow for a learning curve and budget some time to familiarize yourself with the tools available. Plan at least 30-60 minutes for your first time experience to access tutorials, and learn how to navigate the menus and other features. See the section titled “Avatars” for more details.
Don’t Overdo It
As people get used to new XR devices, they may find it very natural and enjoy the experience, or they might not have a tolerance for more than 20–30 minutes at a time (this is especially true with VR, where some people even experience some form of motion sickness). Although “simulator sickness” is more common in content such as movement-intensive games, we do recommend keeping VR meetings to no more than 30 minutes until you get comfortable and then working up to longer sessions.
