1. What is VR?
Virtual reality (VR) makes use of computer technology to create interactive virtual experiences viewed through a headset. Users are placed ‘inside’ a simulated world potentially giving a greater sense of immersion than is experienced through a 'traditional' flat screen.
VR is distinct from 360 video, which is filmed using special cameras, workflow and techniques, but still shares many concepts with traditional video. Making a VR experience is much more akin to making a computer game and might involve programmers, spatial sound experts, technical project managers and more.
This guide is for producers considering making VR experiences for the BBC. It's designed to help you understand the risks and the possibilities of VR production and how the BBC VR Hub can support you.
3. How much does VR cost?
VR can be made for relatively inexpensive mobile devices or powerful computers with high-end headsets. Click 'Choose' to find what you might get for your money.
4. How will I make the experience?
You’ll need to access different skills to traditional TV production to produce a successful VR experience. Depending on the scale of the project, you may need programmers, 3D modellers, motion capture experts, animators, spatial sound experts, VR user experience designers, technical project managers and more.
Consider all of these questions:
- How will people see this experience? What size is that audience?
- What platforms will this experience be made for?
- How will I build this experience technically?
- Is the budget realistic for what I want to produce? Is there time and money built in for prototyping and user testing?
- If you are using a VR company, has it got a good track record in making VR experiences?
- Once I have finished the project, how will I distribute and promote it?
5. What are the creative issues?
Ask why the story is right for VR
Most stories will probably be best told in a different medium, so make sure you have a compelling reason to create a VR experience. If you do have the right story, however, VR can open up exciting creative opportunities.
- With VR you have to let go of control. Allow your audiences to explore the worlds in which they find themselves
- Recognise that the pacing of VR is very different to TV. Some users may want to look around, others will want to be guided by the story
- Consider the level of interactivity. With too little control users miss the chance to affect their world; with too much the story gets diluted
- At each point ask if the interactivity is enhancing the experience or getting in the way of the story
6. What are the UX considerations?
Good user experience (UX) design is essential to creating great VR experiences. In addition to designing the user interface (UI), it's important to consider the range of ways a user can interact, such as gazer control, voice control, gestures and more.
- Be aware that when VR is designed incorrectly it can cause motion sickness in some audiences
- Consider the role of the user in your VR experience. Are they a character in the story or are they an invisible observer?
- Use dialogue, music and sound effects to steer users' gaze within the 360 environment. Spatial audio is important to immerse users and guide them
- Remember that each platform will have its own technical specifications to meet
Try lots of VR experiences, talk to professional VR producers and contact the BBC VR Hub before you begin a production.
7. What tech is involved?
There are numerous devices from the high-end headsets such as Oculus Rift and HTC Vive to the more affordable Samsung Gear VR and Google Daydream. The affordable kit will be available to more people. The high-end headsets require a powerful PC to run and will be prohibitive for some users.
Before you start:
- Identify your audience. Make a decision on hardware based on who you're trying to reach
- Decide where your VR experience will be published - there are numerous options and each has its own requirements and developer specifications
- Ensure your research is up to date. This is a rapidly changing area so get in touch with the VR Hub for the latest advice

VR is a relatively new medium that offers exciting possibilities for telling stories in innovative ways. It’s also a very different way of making content from traditional TV, film or even 360 video. BBC staff should contact the VR Hub for advice before they start. If staff want to explore further possibilities, contact David Johnston from the BBC R&D Reality Labs.
