Virtual Reality Shoot Tips: Distance and Personal Space

By: Stacy McKenzie  – Director of Lucid Studios

Personal space is a major feature of shooting in 3D virtual reality.  When used well it can be an absolute asset for telling your story. If you want to create an intimacy between the subject that you are shooting and your viewer by comfortably putting them closer together in a conversation, personal space is a great place to start. In the reverse, if you want to create tension, depending on the relationship that you want to achieve, you can use an infringement on personal space to do so. To prepare for, and understand, shooting interactions in VR you should keep in mind a few things;

  • Personal space is culturally defined. Some cultures have more personal space and others have less. You should take into consideration the predominating culture of the audience who will be watching your video/film. Also, have a sense personal space norms of the culture that your subjects are either from or are currently in.

  • Who is your camera? In virtual reality the camera can either be an omniscient observer

or a character itself.

This role of the camera will be established relatively quickly into the video/film. By knowing “who” you want the camera (ie. the viewer) to be, you define where your camera is going to be and how it is going to move through the world. I will go into this more in another blog post. Be thoughtful and prepared to use personal space to your advantage to set a tone or move your story along.

  • Know your equipment. Every camera is different. Some of them are able to move freely within a scene, and some of them are locked into a location for better or worse. When you choose your set up and choose your camera, you should do some tests with people and objects to get an authentic “feel” for the distance of things. It helps if you are using a camera that can do a live stream in VR so that you can see how close something feels in the moment. For example; when working with the Lucidcam, I am often shooting scenes in a first person perspective. Even though this camera shoots in full and authentic 180 degrees, there is a feeling that you are actually 6 inches to a foot closer to your subjects that the camera actually is. This might just be part of the process of acclimating to VR, but nonetheless the feeling is there. If I am shooting in the United States (and my characters are in/from the United States), I know that the normal personal space distance to stand from a subject is around 3 feet, and I will make sure that my camera is 3.5, sometimes even 4, feet away as a comfortable baseline.

Once you have a decent grasp on the use of personal space in a scene, you can start applying the same concepts to the viewers interactions with every space and depth in general. You can start manipulating depth to shock the viewer or draw them into details that you want them to notice.

Critical Impact on a Viewer’s Virtual Reality Experience: 360 2D Vs. 3D Cameras

How the Differences in Building 360 2D Vs. 3D Cameras Will Shape VR Adoption?

The definition of Virtual Reality has been evolving over the last couple years. While we are all clear about what a VR headset is and what it needs to do, people often are confused about what VR cameras should be able to do. Is it 360° or 3D or both? There is clearly a hype around 360° 2D consumer cameras right now, but the wave of 3D cameras is not far behind. However, to bring more clarity around why 3D is still behind, this article should explain some of the differences and especially challenges which make building 3D cameras much more difficult than a 360° 2D camera.

2D vs. 3D 360°: More than Just a Couple Lenses

First of all, the amount of camera modules and lenses needed to do 2D 360° is at a minimum two and can go up to four, but 3D needs way more than that. If you imagine that capturing 3D in one direction can only happen with at least two lenses – as we reproduce what a human eye can do in stereo – then you will understand that the most you can achieve in 3D with two wide angle lenses is 180° through and with six lenses is 360°. It is possible to create 360° 3D with four lenses, two facing one direction and two facing the opposite, but then you are sacrificing the sides which will be only in 2D. Many 3D cameras use eight or more lenses to create 360° 3D, because the more lenses you use the better resolution you can achieve with stitching.

Straightforward Vs. Additional Alignment: Manufacturing 2D and 3D

Second, 360° 2D cameras have a more straightforward manufacturing process than any 3D camera for Virtual Reality. In the assembly, two lenses are mounted on sensors back to back, and the key step is the mechanical calibration to precisely align them. However, 3D VR cameras have to go through the same step in manufacturing, but then add an additional software calibration process which guarantees a perfect 3D experience. Every single 3D camera has to go through that process in order to generate 3D data necessary for playback.

Stabilizing Multiple Points: Image Processing in the 2D vs. 3D

Finally, image processing needs for 3D cameras are much higher than for 360° 2D cameras because of stabilization, high dynamic range and calibration. For 360° 2D, you need the stitching software to combine the two lenses, and that happens mostly in real-time. However, for 3D cameras, you need more than just stitching, since you always have two reference points which you need to consider instead of one like in 2D. That means when you stabilize 3D, you are not stabilizing one point, but multiple points in differently shaking images. It can create a huge challenge, as for a perfect 3D effect and depth, you would need to keep the reference points at the same distance. Another impact is on the high dynamic range between two lenses capturing with a slight offset.

Even though you are recording the same direction, the light might be different due to the offset of the lenses. Besides those two you have to also deal with calibration which we briefly discussed above, but not just in manufacturing. What happens when the camera falls on the floor and the lenses get misaligned?

Those are just a few reasons why building 3D cameras is so difficult and needs time to get right. The smallest error can cause a huge impact on the viewer, leaving behind an experience which keeps people away from ever adopting Virtual Reality. Therefore, ramping up 3D cameras have taken an incredibly long time compared to all the 2D 360° cameras in the market. All we can hope is that the computer vision technology for 3D keeps getting better and better over the next couple years to finally take true VR content to the next level.

Consumer Insights of 360 VR cameras

In the last couple of months, many Virtual Reality cameras have come to market which try to put content creation into the hands of consumers. However, sales of these VR cameras have been only moderate with the Ricoh Theta and Samsung 360 leading the pack. Because the unexceptional sales volume surprised us, we have collected the feedback to see what is holding down the pace of purchase.

Most consumers who bought a 360 VR camera mentioned that the big thrill in owning a VR camera  frequently faded after a few weeks, and after only using it a couple of times. This feedback was consistent and widespread and really surprised us because purchasing a VR camera is not only expensive but also requires time and effort to learn how to operate. Therefore we looked carefully at the user experience, storytelling and day-to-day integration to try to determine why consumers are not completely satisfied.

The first barrier is simply getting consumers ready to actually make a purchase. When consumers enter a retail store like Best Buy and walk past the unusual  ball-shaped camera devices, at first glance it does not quite resemble a camera at all, and it’s not very intuitive in terms of how to hold it and see what it captures. The biggest difference between a techie and consumer is the amount of effort he or she is willing to put in to learn a new technology. While a techie would spend hours researching and learning how to operate a 360 VR camera, the average consumer is more impatient and wants the device to directly function. Since the 360-degree camera capture experience is completely different from traditional digital cameras, there is just no obvious reference point for a consumer to know how to easily use it.

The second barrier to purchase or use is related to the 360 content itself which is very different from what consumers are used to — the 16:9 frame. With 360 degrees you pretty much capture everything, meaning you have no option other than to include things you want and things you do not want in the frame. This raises two more problems. First, consumers like presenting themselves from their best side and in the best light, but now they no longer can control that because it would take too much effort to make sure all 360 degrees look great. Second, consumers like telling a story by framing the perfect moment, and now they have to find other ways to direct the viewer’s attention. Given these challenges, it makes more sense that most 360 VR cameras are bought by professionals now. They either have the time and resources to stage 360 degrees or know the ins-and-outs of storytelling with sound and movements in 360 VR.

Lastly, portability and ease of carrying is a huge factor for consumers. Most of today’s pictures and videos are taken with smartphones because it fits into what you are already carrying like your phone in your pocket. However, 360-degree cameras are normally the size of a ball which often does not quite fit into your pocket and requires a bag or a mount in order to carry them around.

The only one which does fit is the Ricoh Theta which is almost the size of a smartphone, but still needs to be connected through wifi to a phone. The best integrated solution would be a 360-degree camera embedded into a smartphone, but since today we don’t want to buy thick or bulky phones, it would have a huge impact on the design of the smartphone.

360-degree Virtual Reality cameras are a great invention, but their value add compared to a standard panorama shot by a smartphone is small compared to the price you pay. We do not know if 360 VR will hit mass consumer adoption, but we know that professional videographers and content creators love capturing and developing commercial experiences with it. Therefore we believe that consumer adoption of 360-degree cameras will be way behind actual 360 content produced for commercialization.

Why 3D cameras will finally take off

For decades humanity has experimented with binocular cameras, trying to reproduce the same sight we have in 3D. One of the first 3D cameras, Verascope f40, came out in 1938. But why hasn’t everybody gotten their own 3D cameras these days to capture their experiences—just as they have with their GoPros?

Three major reasons have kept 3D cameras from mass adoption:  availability of viewing devices; sociability of 3D content; and the maturity of 3D technology.

First, until recently the only way to watch 3D content had been through an expensive 3D TV or a side-by-side view-master. As the Virtual Reality industry has ramped up and more head mount displays saturate the market, viewing 3D content has become easier than ever.  Today viewing videos or images captured with 3D cameras or even VR cameras is possible not only on an expensive HTC Vive or Oculus Rift, but also on anybody’s mobile phone with a Google Cardboard. This has drastically increased the devices available for viewing 3D content.

Second, capturing 3D content and viewing it on a 3D TV would allow you, your friends and family to view it, but sharing it with someone remotely or exciting someone to jump into 3D content creation was not possible. Although Virtual Reality, especially mobile VR, allows you to transfer and watch 3D content easily, it is still an isolated experience. However, when you consider that a 3D TV costs thousands of dollars, you now need only a mobile phone and low-cost Google cardboard to view 3D content. And as I believe that VR headsets will replace mobile phones in the future, the options to consume content created by 3D VR cameras will exponentially increase.

Lastly, one of the challenges 3D technology faces, especially 3D displays, is the angle from which the person watches the video on the screen. If you are not standing directly in front of the screen at a 90° angle, the 3D effect does not work and can cause people to feel uncomfortable viewing it. Many companies have tried to make VR content viewable for everyone. Solutions range from shifting screens to segmented depth calibrations to eye tracking paired with customized playback. However, none of these technologies can currently ensure a comfortable and fast viewing experience for 3D content. This is another area where Virtual Reality headsets provide a much easier solution by literally mounting the screen directly before your eyes and using an accelerometer to adjust the display as you move your head. The additional data coming from the accelerometer provides the feedback needed to directly adjust the 3D, making it comfortable to watch. As VR technology matures, 3D playback will continue to improve.

Affordable and sophisticated VR Headset will improve consumers' experience with VR and bring it closer to the mass.

As we have seen, Virtual Reality can finally provide a scalable platform for 3D content which was never possible before. The more VR is adopted in the coming years, the better the solution for viewing, sharing and displaying 3D content created with 3D cameras. As the VR market becomes saturated with head mounted displays, the market will not be satisfied with purely 2D 360° content, but will demand more and more true 3D content, thus giving 3D cameras the chance to come back from its prematurely-announced demise.  

How about you? What is your opinion on 3D camera?

LucidCam is the easiest-to-use VR camera out there and can enable mass content creation

The camera’s unique technology was created by our founders, Jin and his co-founder and Dr. Rowell, a Stanford Ph.D. in Electrical Engineering who is specialized in computer vision and image processing. LucidCam breaks down expensive Hollywood 3D production camera systems to a small form factor, making it more affordable for the masses and eliminating the long-winded postproduction processes. It leverages binocular lenses to create true depth as well as peripheral vision and utilizes two microphones — essentially mimicking human eyes and ears. It fits into your pocket like a mobile phone so users can capture immersive images and videos anywhere, anytime. With a 180-degree field of view, LucidCam allows users to stick to the traditional point-and-shoot approach, simply pressing the shutter and holding the camera steady to capture everything – no panoramic sweeps required.

We will be bringing a remarkable VR camera to capture great immersive videos. There are so many applications for 3D VR content, but the potential is limited when only a few people have access to the tools. With LucidCam we want to put the power of content creation into your hands, because only then the potential of VR will unfold.

Meet AR… The Sister of VR

Blog by: Micah Blumberg

Micah is a freelance writer with Virtual Reality Media Associates

I’ve talked a lot about Virtual Reality. Now, we’re going to change directions a bit and meet the related Augmented Reality company, Meta.

Right now Meta is about 80 people and they are hiring. They previously secured 23 million dollars, sold 1000 Meta 1 headsets, and now they have just released the Meta 2 headset for 949 dollars, it is a real step forward in the evolution of human tools, one that will lead to the replacement of flat screens like those used for TV, computers, tablets, laptops, and phones. With the Meta 2 development kit you can do holographic telepresence, and you can do work in a remote way that is also very immersive. Meta is a see through device unlike Virtual Reality. You can create new programs for it with a game engine called Unity which runs on Windows. Later this year Meta will support Unity on Mac as well. It’s a stereo 3D display so you can see objects in real 3D. The headset’s sensors measure depth, and recognize gestures. With Meta people can work together from different places, and hand each other data as if they were in the same room.

Will Social Engagement Save VR?

Blog By: Janessa White

The rise of the internet didn’t originate from search engines, news sites or web browsing. In a time where dialup connection and computers were expensive, mass adoption of the World Wide Web was predominantly motivated by forms of social engagement: chat rooms and email.  People were rushing to get online to interact with one another.

Virtual reality right now faces a similar predicament the internet did in its early days: how do you get people to adopt to a new medium? As history has proven, it won’t be through games, films or other forms of entertainment. Until we can incorporate social media and social engagement into the VR space, this industry may remain a bit obsolete on a mass scale.

Geek.com recently published an article ,‘The Dream of Virtual Reality is Dead for Now,’ throwing quite the gut punch to the VR industry. The article’s author, Will Greenwald, states that until higher quality headsets are more affordable, the industry won’t prevail. What he’s missing in his argument is that companies like Oculus predict it will take five or more years for mainstream adoption of VR. Sony, Samsung, Google and other players in the VR industry are all taking similar approaches: they’re in it for the long haul.

How do you turn a singular experience as stark as putting a VR headset on into a communal or socially engaging activity? Harvard professor Mikolaj Jan Piskorski has spent years studying user behavior on social media platforms. What has he concluded? It’s all about pictures, voyeurism and cloaked engagement. Users spend hours online looking at funny photos, gawking at the lives of their friends or acquaintances, getting furious over the latest political debate recap and messaging with friends and family.

How can VR take from Piskorski’s learnings? Perhaps the future of VR is chatrooms like AltspaceVR , where your avatar engages other avatars? Maybe Skype will transform into a virtual arena? Or maybe we’re looking in the wrong place and AR will trump VR by a long haul and we’ll someday wine and dine with holographs of our favorite mythical creatures as teased out by Magic Leap?

An Environment in Altspace VR

If virtual reality is to make the splash we all hope it will, it has to find ways to connect us as humans. Through stories, social media platforms or other forms of human engagement we may find the key to unlocking mainstream VR.
