Qualcomm announces new Snapdragon 845 VR reference headset

Qualcomm today revealed a new reference design for a Snapdragon 845 VR headset. The headset uses the similarly named mobile Snapdragon 845 system architecture that the company announced last month, which can be used for both VR and AR.

The Snapdragon 845 headset is capable of displaying two 1024 x 1152 pixel screens at 120 frames per second, which is subpar compared to many existing headsets. (HTC’s Vive Proheadset offers 1400 x 1600 resolution per eye, for instance.)

3D SCANNING ENTIRE ROOMS WITH A KINECT

Almost by definition, the coolest technology and bleeding-edge research is locked away in universities. While this is great for post-docs and their grant-writing abilities, it’s not the best system for people who want to use this technology. A few years ago, and many times since then, we’ve seen a bit of research that turned a Kinect into a 3D mapping camera for extremely large areas. This is the future of VR, but a proper distribution has been held up by licenses and a general IP rights rigamarole. Now, the source for this technology, Kintinuous and ElasticFusion, are available on Github, free for everyone to (non-commercially) use.

The best VR and AR from Sundance 2018, from haptic gloves to alien abduction

The Sundance Film Festival’s New Frontier experimental section featured its first virtual reality experience in 2012, and with every festival, its projects have grown longer and more sophisticated. This year was no exception. The program included more than 20 virtual and augmented reality entries, ranging from simple mobile 360-degree video to multi-person performance art installations.

Many of these pieces came from well-known figures in the VR film and art world, attached to studios like Within, Felix & Paul, and Oculus. But 2018 also saw strong projects from relative newcomers, and a couple of absences, including Nonny de la Peña, who created the first Sundance-selected VR piece and has been featured at the festival multiple times since then. This year, people used familiar formats for more sophisticated storytelling, while others channeled newer ideas like multi-person VR and haptics into crowd-pleasing experiments. Here are some of the best.

The MAYA Principle: Design for the Future, but Balance it with Your Users’ Present

The following is an interesting article talking about a principle called MAYA which describes why some products get adopted successfully and others failed.  MAYA stands for Most Advanced Yet Acceptable and is based on the premise that design needs to be advanced, but not more advanced than what users are able to accept and embrace based on their norms.   This becomes relevant especially when talking about AR and what will users find acceptable in terms of wearing a headset in public.

 

“The adult public’s taste is not necessarily ready to accept the logical solutions to their requirements if the solution implies too vast a departure from what they have been conditioned into accepting as the norm.”

A guide for new HTC Vive owners

If you’re a new HTC Vive owner, here’s a nice guide to help you get started in getting the most out your experience with your headset

Figure out what your IPD is

The first thing you want to try and do is figure out what your inter pupillary distance (IPD) is.  IPD is the distance between the center of your pupils between your eyes and is important to set properly to minimize eye strain and be able to focus on the image in front of you.

The most accurate way you can do this is by going to an eye doctor and asking them to measure it for you.   They have a machine which they can quickly and accurately measure this and tell you the number.   It nice to be able to have an accurate measurement done, but if you don’t have it, there are some alternatives.  For example, you can use a mirror and ruler to help measure your IPD by following the procedure in this link here or an online tool like this one here..  For good measure here’s another link to another reference: Link.  At least one of these should get you going.

On the Vive headset, you can mechanically adjust your IPD setting on the headset using the knob on the side and it shows you the IPD setting in millimeters.  Remember that adjusting IPD is correct for alignment, not focus.

Focus

When you first put the headset on, you should try and adjust the two knobs connected to the headstrap by pulling them outwards and rotating them to bring the screen closer or farther to find the best distance for focus.

In general, bringing the screen closer to your face will increase the field of view (FOV) and the amount of display you can see and may slightly increase the size of the sweet spot for viewing for you.

It is important to note that the screen will have a sweet spot where things will be in focus so you need to align the headset so your eyes are in the sweet spot.  By moving the headset up/down on your face, you can adjust your eye position relative to the screen and you should adjust your straps on the side and top of the headset to hold it in place securely so it doesn’t move around.  The next step will be to adjust the settings within SteamVR to improve the resolution within the headset which will be described a little bit later in this guide.

Face Cushion

The HTC Vive comes with a foam face cover.  One thing you will realize quickly is that it gets soaked with sweat easily so it’s nice to get one of these replacement leather covers instead because it’s easier to clean with alcohol wipes between uses.  There’s lots of choices for these (here’s an example Amazon link) and as I mentioned earlier, the thinner the pad, the closer your face can be to the screen to get a larger field of view (FOV).

Deluxe Audio Strap (DAS)

The standard HTC Vive comes with velcro straps and you need to also use external headphones.  There is a deluxe audio strap option which is much more comfortable to put on because it’s rigid and you can put it on like a welders helmet and you just need to tighten a knob on the back to sit comfortably.  It also has a built in headphones so you can easily take the headset on and off without a lot of fuss.  If you don’t have it already, this is a $99 add-on.  Amazon link

Wrist Straps

Perhaps HTC has improved the quality of the wrist straps, but when I got mine, they were notariously weak and susceptible to breaking.   I thought I was immune and controlled enough that it didn’t apply to me, but let’s just say the controller ended flying across the room and smashing into the wall when the strap broke.   I bought a set of Wii straps and those have worked great since.

Watch out for Sunlight and bright lights

One thing to note is that because you have powerful lenses in the HMD to magnify the screen to get a large field of view, you need to be careful not to let sunlight or very bright lights to shine into your headset.  Basically you can burn out part of the screen if you’re not careful.  Just think about the folks who looked into the sun during the eclipse and burned spots into their retina.

Optimizing the experience while wearing the headset

Now that we’ve covered the physical parts of the headset, the next section will be to discuss how to optimize your experience while wearing it.

There are two pieces of software which are highly recommended you get:

  • OpenVR Advanced Settings Overlay Link
  • Revive – Play Oculus-exclusive games on the HTC Vive Link

OpenVR Advanced Settings Overlay

The OpenVR Advanced Settings Overlay gives you the ability to control many of the settings that you want to be able to adjust while wearing the headset.    Three of the main things that I find it is most useful for:

  1. Fixing the floor calibration.  Sometimes when putting on the headset, the floor height is a little off.  You can tell because if you put your controllers on the floor, they are either floating in the air, or underneath the ground.  The OpenVR advanced settings tool let’s you fix the floor with two clicks of the button.  Without this tool, you’d have to rerun the SteamVR setup tool again so this is indepensible.
  2. Adjusting the supersampling rate and compositor render target multiplier.
    • The default baseline is 1.0 for both of these values and if you want to get higher visual resolution and sharper text you can increase these values.  Note that increasing these values will scale the workload that your CPU and GPU will need process so you want to try and get the best balance between image quality and minimizing dropped frames.
    • In general, adjusting the supersampling rate will increase the general sharpness of the images you are seeing and better to do more of this than increasing the compositor render target.  However, if you increase the compositor render target, you will see things like the text on the SteamVR overlays and some overlaid menus become much clearer.
  3. Adjusting the audio settings.  This let’s you control which audio device is used and let’s you control if the audio you are hearing is mirrored on your PC’s main audio output as well.    Sometimes the audio source selection can be finicky if you power up/down your headset and it doesn’t detect your default audio device, so sometimes you need to switch it back to the HMD when starting up.

Revive

There are some Oculus application store exclusives and Revive enables you to play them through your HTC Vive within SteamVR.  You will need to set up an Oculus account, and once you install Revive, then your Oculus store games will be available to you similar to your native SteamVR games.
