First Impressions from the New Oculus Rift DK2 3D VR HMD

September 10th, 2014 · 12 Comments · 3D / AR / VR / HMD


It is time to share some first impressions from the new Oculus Rift development kit after playing with it for a while already, sharing this a bit late due to the arrival of the DK2 coinciding with a planned vacation… a vacation without the Rift in the real world and not in the virtual one. I should note that the following first impressions from the second development kit are from someone that has used the first development kit quite a lot, so there will be a lot of comparing between the two. So let us get started…

Starting with what is new, the new Oculus Rift DK2 comes with a 1080p OLED display, something that was really needed in order to improve the level of detail that the older smaller resolution 1280×800 LCD display provided, especially considering the fact that due to the way that the Rift works you only get half of the resolution per eye and not the pixels of the whole screen are actually being used. The new Oculus Rift DK2 also comes with a new better looking design and a bit more complex setup as it includes an extra infrared only camera used to track the integrated active IR led markers in the headset. The headset weights slightly more as it has the external control box that the previous kit had (essentially the screen controller electronics) built inside in the DK2, but the few ore extra grams don’t seem to be a problem. Another interesting improvement is that the new DK2 comes with only two sets of interchangeable lenses instead of the three that the first dev kit had, the lenses are slightly better in terms of optical performance and seem to be slightly larger, however the total FOV of the new DK2 seems to be about 10% smaller as compared to the 110 degrees available with the first dev kit.


The included web camera is something that we don’t like that much. It seems to essentially be a standard web camera with a filter applied to the lens to block the visible light and pass only infrared light. The idea is to track the specially positioned IR leds inside the front and side parts of the headset and use that extra positional information to add extra sense of realism inside the virtual world. The idea is generally good, however the range that the camera operates in is very limited and if you start moving more you can quickly get out of the range and the extra functionality such as leaning or crouching in the virtual world as you do the same in the real world disappears. Other than that the camera tracking is probably used to also help fighting with the drift that the built in sensors for tracking head movement are prone to. The web camera tracking makes things more complex and limits your movements more than it gives you freedom and the advantages are actually not that much, so Oculus should probably think of alternatives to replace the camera-based tracking. If they want a device like the Oculus Rift to be successful and go mainstream it should be easy to setup and use and not complex to setup and use and limiting the experience of the users.


A few words about the display, it was a bit of a surprise to find the screen from a Samsung Galaxy Note 3 inside the Oculus Rift DK2. But it was probably not very easy for the company to find a good and small enough in size 1080p OLED display that will not cost a fortune and even though Oculus is now owned by Facebook the number of produced development kits is not so high as to get a screen specially developed for them. With that said the OLED display inside the new DK2 is definitely a serious improvement over the previously used LCD panel, though it is still not the perfect screen for the Rift. Resolution wise the new display is definitely a serious improvement, though you can still see the pixels zoomed though the lenses, so an even higher resolution screen is needed for the final consumer version in order to really polish the experience. The higher resolution however also causes some concerns about the need for more processing power from the graphics card of the computer used to power the Oculus Rift, so initially there will most likely be some compromise. If you were hoping the 1080p screen to be enough, then you will be left disappointed it is not enough when zoomed through the lenses and split between the two eyes.

What the new OLED display does pretty well, though not perfectly, is to almost eliminate the annoying and nausea inducing for many people motion blur while panning around. The low persistence OLED display does a great job, though we have noticed that in high contrasting scenes where you have dark objects surrounded by light background you can still see some motion blur. For example the standard Oculus demo the stairs inside the house or the trees outside by the wall – depending on the version of the demo you try. The version of the demo included with the SDK apparently is somewhat darker and in it the motion blur is noticeable when looking around the stairs and on the standalone version of the demo that is apparently brighter the motion blur is noticeable when looking around the trees outside. A bit of a disappointment, but not that bad actually to ruin the overall great experience that the bright and high resolution new OLED display provides.

The new lenses, only two sets, seem to offer better optical quality and somewhat different distortion. While the lenses are bigger the actual FOV you get is slightly reduced, but still more than great. The expectations that the larger lenses would also provide a larger sweet spot for viewing without seeing some chromatic aberrations caused by the distortion of the optics ended up in vain however, maybe this needs some more work on the software side responsible for the distortion of the images displayed that need to compensate for the distortion of the optics. The good side is that the standard lens works pretty well for people that are wearing prescription glasses and are nearsighted as if your glasses are not so strong you will most likely have no problem using them instead of having to wear the glasses. The same lens is for people that don’t have problems with their vision and the second lens is for people with worse eyesight apparently, so it is like Oculus decided to “keep” the B and C lenses from the first dev kit in terms of capabilities.

The new DK2 comes with a new mode that may help greatly in the usability of the device as it can output directly to the display of the Rift the compatible applications without actually having the device as an extended or cloned display like you had to before that. This however will work only with applications compiled with the new versions of the SDK supporting the DK2 and since there are also quite a few other differences the applications designed for the DK1 should be updated to be properly used on the new development kit anyway. You can of course still use the Rift as an additional display available to ensure compatibility with older apps and to allow for more flexibility of the use of the device. The new Direct to Rift mode is a good example of the way Oculus should be moving – making things easier and working problem free from the user and not having to bother him with things like moving primary displays or having issues with Vsync and tearing… just open the application and it will automatically appear where it should be – on the display of the Rift.

With all of the above said the new Oculus Rift DK2 is definitely a nice improvement from the first development kit and if it is the first Rift that you get to try you will be really excited and pleasantly surprised from the experience. If you however have tried and used the first DK1 you may not be as excited from the improvements and changes even though they are not small, they are simply not enough to get the DK2 to the level of the product that should be offered to the end user. There is much more work needed to be done and we may need to get a 3rd version of the dev kit next year that will be closer to what the consumer version might be and expect an end user product probably by the end of next year of things continue to progress well.

My Pre-Ordered Oculus Rift DK2 Unit Has Finally Been Shipped

August 8th, 2014 · 12 Comments · General 3D News


The day has started with some good news, the Oculus Rift DK2 that I have preordered has apparently been shipped, so hopefully next week I’ll be able to share some first hand experience with it as well as to compare it to the old dev kit. This time Oculus is apparently shipping the units from UK for orders from Europe, so this should make things easier and faster than last year when they were all shipped from USA. Do note however that this pre-order for the DK2 was made in the first day after the pre-orders have been announced and it has been shipped near the end of the second week that Oculus has beens hipping. So if you have preordered a unit later on it may take some time for your to arrive and if you preorder just now your unit will most likely be shipped sometime in September according to the Oculus website.

The Current Situation with 3D Vision, Something We’ve Already Seen in the Past

August 3rd, 2014 · 12 Comments · Other S3D Tech

It has been a little over 5 years since the start of this blog, even though I has been a stereoscopic 3D enthusiasts for much longer, the reason for the existence of the blog was Nvidia’s 3D Vision. I was really excited when they have announced it and when the first 3D Vision-ready monitors started appearing on the market I was eager to get one as I really did see the potential that the technology had for gaming. And back then since it was something really new and exciting I decided to share my experience, knowledge and other useful information with other users that were just starting and this is how this blog was born.

Now, five years later we are seeing a deja vu as the situation with 3D Vision is pretty much the same as with the Nvidia Stereoscopic 3D Drivers that were available before the birth of 3D Vision. Nvidia did create a market and strong demand for products at first, however they slowly start to neglect things and in a few years they kill the market. This is exactly what is happening with the 3D Vision now as Nvidia hasn’t done almost anything new in many months. The latest bigger things were the announcement of the G-Sync monitors, some with 3D Vision support, that however were greatly delayed to market. The other more recent thing is the addition of “3D Compatibility Mode”, but the more important thing – supporting and pushing game developers to integrate Stereo 3D support in games has been long gone. It is not about fixing games after they have been released, but integrating proper stereo 3D support while they are being developed.

The stereo 3D gaming community can do the fixing with the help of tools like Helixmod wrapper, however even the game modders are giving up on 3D Vision as instead of helping them Nvidia seems to be doing just the opposite. This is really discouraging and if Nvidia does plan to abandon 3D Vision like they did with their old Stereoscopic 3D Drivers, then they should at least open the project and not kill it completely. The people in different stereoscopic 3D gaming communities that are using 3D Vision have asked numerous times that Nvidia works on something or improves another thing in order for 3D Vision to become better and easier to be used, but we have not seen any results. This is really discouraging and many people have just decided that it is enough for them, some of you might of thing this for me as well due to the last few months with no updates here…

I have not given up on stereo 3D and 3D Vision, at least not yet. I was just busy with other things and have decided to get some rest from 3D, not that very much was happening with 3D Vision anyway, and the Facebook and Oculus deal was a bit of surprise and I wanted to see what will come out of it. So far it seems that things are still good and I’m about to get my hands on the pre-order of the DK2 hopefully next week, so all is not lost. However Oculus Rift is not something that can replace 3D Vision, these are two different things, and even though some of their features and functionality do overlap they are still not the same thing. VR with 3D support is an interesting new concept, but for really good results you need content developed especially for the device, meaning that you not only need a good hardware, but good software support as well. At least here Oculus is doing much, much, much better than Nvidia as Oculus Rift is their only product, unlike Nvidia that has many products and technologies and cannot focus solely on 3D Vision. So interesting times could still lay ahead of stereo 3D technology, so we’ll have to wait and see..
