China using #drones to enforce quarantine

They are being used with sensors to detect people out and about, and to broadcast public health announcements from overhead speakers.

I wonder how long until the AmazonUPSGoogle drone fleets decide to play loud advertising as they fly low over our homes and cities?

“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.

‘Avatar 2’ sequel in 2020 could kick start #3D again

Avatar was a huge success and caused many studios to rush out 3D conversions of existing 2D content – but which were, frankly, terrible conversions.

Certain studios took the time to make high-quality 3D films, but some films that were put into 3D were garbage. As a result, not all 3D was created equal,” says Eric Handler, a media analyst with MKM Partners. “There was a lot that people didn’t want to pay a premium for anymore.”

There’s hope from certain sectors that the release of “Avatar 2” in 2021 could reignite passion for the format. Cameron is planning three subsequent sequels in the coming years, with a fifth installment wrapping things up in 2027.

Olympus says it has no plans to sell its camera business

“For Imaging, however, we currently have no plans to sell the business. The task is therefore to stabilize and strengthen its market position. To achieve that, we are actively running marketing activities, and have already established a clear and exciting product roadmap for the coming months and years. We are actively pursuing future technology developments that will enhance photography and video for creators. Furthermore, Imaging is and will continue to be an important technology and innovation driver for our other businesses.

A few days ago, a Russian blogger posted rumors that Olympus Imaging staff were looking for new jobs and that the camera division would be sold or shut down in January.

Then Bloomberg ran a report that implied the Olympus CEO was not opposed to selling the division, but did so in a unusual way without direct quotes. This only furthered the rumor. (Bloomberg ran a fake news story last year claiming a secret chip was installed on servers at Amazon, Apple and other U.S. companies during manufacturing by agents of the Chinese government, for the purpose of spying. All of the companies and Homeland Security denied any such chip existed.)

Olympus has replied with a statement that it has no plans to sell the business.

The weirdest is that the micro four thirds community that posts to online forums, is the most negative group of people ever met. Those that post frequently focus on gloom and doom and seize upon every poorly source rumor to further their victimization mentality. I do not get this attitude at all.

Olympus is still recovering from their mega accounting scandal in 2011 and like all camera makers, is in the midst of a shrinking market that impacts all camera makers. They have, however, continued to introduce new cameras and lenses and have moved manufacturing to a new factory in Vietnam.

3D theaters continue to increase in number

And while “3D TV” is mostly gone at present, 3D video projectors are very common. Most video projectors support 3D because it is very inexpensive to add 3D to a projection system while it was expensive to put the tech into flat panel TVs.

If you are looking for 3D viewing options at home, 3D projectors are a good option. Another option is 3D computer monitors, which are used in gaming and engineering and other visualization applications.
