We talk a lot about VR allowing people to experience environments or realities that don’t yet exist. But with 360 photos for VR, virtual reality becomes more like a modern-day equivalent of Star Trek’s Scotty. Using the latest 360° cameras, VR can be used to ‘beam’ a viewer right into the heart of an existing location, in a fully immersive image.


 

There are several smart commercial applications for using photography visuals through VR, but before getting into the best of these, we’ll take a look at a few things to consider when capturing 360° photos for VR.

Camera basics
While we won’t get into naming names and choosing hardware favorites in this post, suffice to say, a great 360° camera will do exactly what its name suggests, offer 360 degrees of capture ideally with no need for additional image processing or manipulation to stitch footage together. Camera prices range from about $200 to thousands, but you should know there’s usually a pretty direct correlation between price and resolution. The higher the cost, the greater the resolution. But there’s another significant difference – some cameras shoot stereoscopic images, while many cheaper ones are monoscopic. Stereoscopic cameras: will typically be more expensive and less common. They essentially shoot a 3D rendering of your image for the left and right eye – and this is what amps up the VR effect in a VR headset.

 

Monoscopic cameras: are much more common. They create flat 360 degree images that can be viewed on a screen or in a VR headset, but they have more limited immersiveness and change the degree of depth perception. These are the images you’ll see on a YouTube 360 player.


 

Monoscopic cameras are sufficient for images being viewed mostly without a headset, and certainly for beginners. If you plan to use images often on your website, to promote your business or show off your design work, it’s worth investing in a camera where the software does all the heavy lifting to produce a fully spherical image and also make the process of editing and sharing captured footage quick and painless.

Positioning
The best position for the camera in any scene corresponds directly to where you would stand if you wanted to get the best view. Position the camera in the center of a scene so there is plenty to look at in every direction. Set it to the height of an average person (typically 5’7” in North America) so people don’t feel like they’re either floating or have come to the scene without their legs. Remember that 360° cameras capture everything, including adjustable arms on a tripod if they stick out too far. Popular alternatives to tripods for 360° shooting are light stands, as they have small fixture points and no levers to reach into the shot. You also need to ensure you personally don’t feature in any footage being captured, if you don’t want to be seen. Fortunately, most 360° cameras come with the ability to activate them remotely via a mobile app enabling you to find a good spot to disappear.

Some key use cases for 360 Photos for VR:
Remote viewing
The ability to immerse viewers in existing environments via VR is particularly effective where distance is an issue. For overseas real estate investors, the ability to remotely tour potential new property purchases is pretty powerful. Photo VR lets them experience actual room layouts, style, and specifications without going on lengthy and expensive long-distance trips. We contributed to an interesting piece for South China Morning Post on how this growing phenomenon is changing the overseas property buying market in China.

Portfolio demonstrations
By creating VR experiences from 2D designs, virtual reality has dramatically changed how the allure of an unbuilt property can be communicated to a potential buyer. In the same way, capturing 360° imagery of completed projects and allowing potential new clients to view these via VR is a great way to communicate your work. With entire virtual portfolios able to be held on a mobile device, having a lightweight viewer such as a Homido on hand means these types of immersive virtual presentations can also be done anywhere and at any time.  

Comparing Current to Future
Using a combination of 360° imagery and computer rendered designs, those in commercial real estate are now able to demonstrate the current and future look of commercial dwellings in parallel. Using 360 photos for VR, potential tenants or commercial buyers can remotely view properties in their current form. Combine this with a traditional CAD rendering of what could be, or a 360 photo of a similar completed space to help visually transform the space.  



Beyond these few, there are numerous other use cases where 360° imagery used within VR is offering marketers, educators and sales teams unique ways of engaging and informing audiences. From virtual retail stores to virtual training and virtual tourism, the ability to immerse people in real environments that are either too remote, sensitive or dangerous to be easily experienced in person, is having a growing impact on businesses … and it’s only just getting started.

VR has a – rightly deserved – reputation for causing some users to experience nausea. It is even the namesake of a new form of “motion” sickness – VR sickness. The experience is one a lot like sea or car sickness; cold sweats, clammy hands, headaches and, for some, a quick ‘reach for the trash can’. There are various theories about what part of the eye/brain/motion mismatch causes VR sickness and we’ll look at that in this post. But no matter the cause, you should be aware of how nausea (or the fear of it) may impact your clients’ willingness to don a headset when you share VR experiences. And how to solve the issue.  

So what is actually happening?
Virtual reality-induced nausea didn’t enter the fray with the first Oculus Rift. It’s been around since the first astronauts, airline pilots and test drivers began honing their skills in virtual environments. In fact, it used to be called ‘simulator sickness’. It’s caused by a sensory mismatch between the vestibular (the balancing system in your inner ear), the visual (what you are seeing) and/or the kinesthetic (your physical movement).

During a VR experience, a user’s eyes might be transmitting signals to the brain that it’s test driving a new Audi on the Nurburgring. But signals from the inner ear are recording no matching movement and this sensory conflict can trigger illness. According to some experts, this impulse to be sick is brought on by a self-preservation reflex. Mismatched sensory signals make the brain think a poison has been ingested by the body and it acts to get it out. But that’s just a theory. VR-related nausea won’t affect everyone. Based on those who experience motion sickness on boats, planes or in cars, estimates say it will affect around 25% of people. Women are also said to suffer more than men with motion sickness in general. Factors for this include postural sway, whereby women’s smaller bodies may mean they sway more when standing or sitting still, and women typically have a heightened sense of detection when it comes to sensory conflicts.  

How to combat VR Sickness
Anecdotally, regular VR users say they acclimatize quickly and symptoms subside naturally. That’s certainly true in our office, where the team members who have been working with VR for years are surprised when newbies mention VR sickness concerns. But that won’t help your client in their first VR experience. Technology can be part of the solution. To reduce the subtle latencies between what is being seen and what movement is being physically experienced, headsets from companies such as Oculus, HTC, and PlayStation VR all now work with refresh rates of 90 frames per second. This ensures minimal lag and cuts down on numbers experiencing negative symptoms. Mobile headsets like Samsung’s Gear VR or Google Cardboard use smartphones to project the images, so the graphics aren’t as sophisticated as tethered experiences. However, since mobile VR tracks only head movement and not full body motion, the effects of VR motion sickness are typically less. The incongruity between what’s been seen and experienced physically is smaller, which reduces the risk.

Getting around the VR motion sickness problem played a part in our decision to concentrate first on mobile as a method of delivering VR for business applications. The flexibility of mobile lends means it can be used in any setting, including places your viewers feel comfortable. And at Yulio we remove the straps from all of our headsets to enable ‘popping in and out’ of experiences. Communicating new architectural or interior designs doesn’t require prolonged periods of full immersion. In our experience, allowing viewers to immerse themselves in a design as they choose but then easily ‘pop out’, reorienting themselves, leads to drastic reductions in cases of nausea and ensures the experience is both comfortable and effective. When business users can raise the headset to view a window on your designs but know they can immediately remove it if needed, it helps resolve concerns about feeling ill and trapped.

With many different subtle factors leading to people experiencing vr motion sickness, there’s no one miracle cure. A quickly growing base of both entertainment and enterprise users, have meant, however, that technologies used to create, record and view virtual reality content are all being steadily improved with the issue squarely in mind.   Thinking about a headset for your business?
