Again: “Breakthrough Glasses-Free 3D Technology on Display at CES 2022”

There have been several interesting 3D solutions including glasses-free, over the years. Unfortunately, the public so far has not been real interested in 3D.

MIAMI, Dec. 28, 2021 /PRNewswire/ — IQH3D will be premiering their glasses-free 3D products at CES Las Vegas 2022 in booth #19274. IQH3D has pioneered a new generation of 3D devices through research and development of Glasses-Free 3D products and advanced software applications that will be on display. Experience the highest quality 3D optics ever produced on a consumer device with the featured product SKYY 10.8″ Streaming 3D tablet. All IQH3D’s devices can be used for viewing 3D content and extraordinary NFT Stereoscopic Digital Art. CES 2022 attendees are invited to visit www.IQH3D.com to learn more about IQH3D’s line of products.

Those that I have seen have looked pretty good, too.

The HP Reverb G2 VR Headset

I just got an HP Reverb G2 VR headset.

I had some difficulties setting it up, plus difficulties getting the controllers paired – and so on. Some of the information at this link will be helpful in overcoming problems you might encounter.

Since I normally use reading glasses, and the G2 has no diopter adjustment, you need to wear your reading glasses or contact lenses when using the system. So far, I have not had success using reading glasses inside the headset – this means I have used it without the reading glass correction – which means a bit much eye strain for now.

I have used the headset in conjunction with MS Flight Simulator in VR mode and this makes an already impressive simulator even better – and yes, it is in 3D then too. For now, the set up each time I launch is a bit time consuming but perhaps I will find some shortcuts.

I expect to have more comments on the G2 in the future. I  have much to learn.

NASA Is Using Red and Blue 3D Glasses to Pilot Mars Rover from Home

Journalists are morons when it comes to 3D:

The quarantine also meant they no longer had access to their special 3D goggles

They literally rave over “VR HELMETS” but tell us that “3D goggles” were unwieldy. Have covered this many, many times.  Many reporters call 3D glasses  “goggles” but then write enthusiastically about VR helmets – this makes no sense what so ever.

“No glasses” 3D Holograms?

Light Field Labs has raised an additional US $28 million in funding to develop and produce free air holographic display technology. They are said to have a working prototype now and the additional funding will enable them to scale up to an actual product.

The aim is to create holographic objects that appear to be three dimensional and float in space without head-mounted gear such as augmented reality or virtual reality goggles.”

The principle people behind the technology had developed the Lytro camera technology. As best I can tell, it may be similar to a digital implementation of a conventional, analog, film-based hologram. In the original hologram technology, you look at a flat image that is, basically, like a window pane. As you move to the left or right, you see the true 3D image visible from that point in space. In the laser-based hologram, the window pane is a film that has recorded light interference patterns.

From the description down the page, here, my interpretation is they have created a currently small window pane that is replicating the light interference hologram concept, but in the digital domain. Obviously, it takes a tremendous amount of computational horsepower and for video, high bandwidth, both of which are becoming available as tech advances.

I presume, also, that this technology can be used to project objects in front of the viewing plane, as is done in stereoscopic 3D. In other words, actors or objects can be appear to be between you and the viewing screen – or behind the screen.

This tech creates true 3D that does not require glasses for viewing.

3D box office revenues have taken a steep dive, with box office sales at their lowest level in eight years. It may finally be time to say sayonara to those bulky tinted glasses.

I would be overjoyed on the day that 3D finally bites the dust. The tinted glasses overly darken the screen, and the rare effects that cater to the technology often only serve to make me woozy.

The reporter writes about films but when it comes to 3D, is a dufus – movie theater 3D glasses are light weight, clear, polarizing filters, not “bulky tinted glasses”. The reporter believes she is wearing tinted glasses when she is not – apparently does not understand the concept of polarized lenses. Since she does not like 3D (sample size n = 1), then no one should enjoy 3D. Wow. If she doesn’t like 3D, then she does not have to watch it, but alas, she wants 3D to be gone because no one should enjoy 3D 🙂
