The December 2022 issue of IEEE Spectrum is here!

While CES doesn’t officially start until Tuesday, announcements and teasers always begin flowing long before the show. From sifting through those materials, I’ve started to spot a few trends.

Augmented reality will be everywhere, while virtual reality gets less attention

This shift is good news for me. Motion sickness makes it unpleasant to fully immerse myself in a virtual world, while augmented reality (AR) devices, which superimpose digital images on real objects, suit me just fine. CES exhibitors will show off lots of new AR glasses at this year’s show, as well as advances in the underlying technology.

Bosch, for example, is pitching a new optical light drive module, a stack of MEMS mirrors, sensors, processors, and other hardware that can be built into smart glasses to create an AR display. Futurus Technology will introduce a mixed reality car windshield. And Magic Leap promises a live demo of new apps as the well-funded AR startup pivots to focus more on business than consumer applications, at least in the short term.

Holography is back in fashion

Holography seems to come and go, as the technology lurches between enthusiasts’ claims that holography is better than ever before and skeptics’ assertions that it’s still not good enough to be useful.

This year, Looking Glass is demonstrating a 32-inch 8K holographic display, with, the company says, a holographic depth that measures in feet, rather than inches.

Hypervsn plans to demonstrate a livestream of holograms, along with a holographic version of Tetris and various holographic virtual assistants.

And those Bosch AR modules I mentioned previously? The company touts a “holographic element” as one key feature of its technology.

Toileting comes to the Internet of Things

I have never seen so many press releases related to poop! Several companies are touting smart diapers for infants and adults. Monit announced adult diapers that contain five sensors and will notify caregivers via an app that a diaper is soiled and “pinpoint the soiled area” to reveal exactly what the caregiver will find when the diaper is changed. The system apparently uses machine learning to get smarter about… what, I’m not quite sure.  

Meanwhile, Charmin plans to demo several technologies “for a better bathroom experience.” (Sorry, that’s all I can tell you right now, details are under embargo. I’ll just say they definitely push the edge of bathroom technology.)

And Toto, the company whose many-featured toilets brought luxury toilet technology out of Japan, where many of us first encountered it, into high-end homes around the world, says its next-generation toilet has added self cleaning, with ultraviolet light and a titanium dioxide coating on the toilet bowl, which together create a photocatalytic process to destroy lingering microscopic particles of waste—for just US $13,000.

Digging Into the New QD-OLED TVs

Formerly rival technologies have come together in Samsung displays

Sony's A95K televisions incorporate Samsung's new QD-OLED display technology.

Televisions and computer monitors with QD-OLED displays are now on store shelves. The image quality is—as expected—impressive, with amazing black levels, wide viewing angles, a broad color gamut, and high brightness. The products include:

All these products use display panels manufactured by Samsung but have their own unique display assembly, operating system, and electronics.

I took apart a 55-inch Samsung S95B to learn just how these new displays are put together (destroying it in the process). I found an extremely thin OLED backplane that generates blue light with an equally thin QD color-converting structure that completes the optical stack. I used a UV light source, a microscope, and a spectrometer to learn a lot about how these displays work.
