Transparent Displays Are Here, But They're Pretty Useless
An anonymous reader writes: Samsung has debuted the first commercial installation of its 55-inch 'mirror' displays at a salon in South Korea with a transparent OLED screen overlaid over a mirrored surface to allow interaction. The Samsung product rivals an equivalent TOLED from Planar, with both intended for high-end use in the retail display and exhibition space. However both manufacturers are struggling to find practical applications for the much-awaited technology. Transparent displays have been a staple of sci-fi films such as Minority Report for decades, but only, it seems, because they helped to open up scenes which would otherwise have been difficult to film. With the pending advent of AR-based visualization, the innovation of the clear monitor seems not only to have come too late, but also offer limited practical use, even if its current breathtaking prices were to descend to the consumer space.
Until you're checking your ass flab for zits in the mirror and accidentally accept a call from your grandmother.
A HUD would actually help enhance visibility by tracking road markings, signs, and obstacles that are low visibility, as well as alerting you of events happening in your blind spots. Integrating 3D maps and directions would be handy. Putting your speedometer and other dashboard information closer to your view could reduce time you take your eyes off the road.

London: transform any day into a bright sunny summer day. downside: more pub brawls ensue after complicated arguments and tense standoffs arise from disagreements about blustery and sunny.
Canada: images of alberta in february could be replaced by video of the leafs Borje Salming waxing your car which you tacitly know damn well has been under 7 feet of snow since october.
America: imagine a mcdonalds window that makes the food appear to have been cooked from ingredients that came from actual vegetables and known animals. Or a convenient window treatment that could some day make Dick Cheney look like a real person instead of a villain from an episode of captain planet.
Good people go to bed earlier.
They should have linked "AR-based visualization"
Not everyone knows what Armadillo-Rhinoceros-based visualization is. It's pretty much zoo-centric terminology.
I've fallen off your lawn, and I can't get up.
I saw these in Vegas last year. Not at a trade show, in shops being used for serving beer, so obviously the cost isn't atrocious:

And people have been doing smart mirrors for ages, and mirror display TVs. Not sure what the "new" hype is about.
Not so simple as transparent displays. I built a HUD for my car a few years ago, and proper optics are essential to the usefulness of a HUD. Essentially, you need lenses or curved mirrors or specially-tuned diffraction gratings to refocus the image some distance away - preferably many feet ahead of the car, so you don't need to refocus on the windshield.
Having information presented at the same depth distance as your windshield, but in the same general direction you're already looking for at-a-distance viewing, is distracting and hard for the eye/brain system to tolerate.
Here's a pretty good overview of HUD optics.

First off, arcade games have been using these for years. Skip to 45 seconds in for an example (volume warning - it's in an arcade so it's loud): https://www.youtube.com/watch?...
There's another arcade game with little fish bowls that's also transparent. It's really cool just to look at.
Also, many years ago, around 20 or so, I took a calculator apart and removed the back-most layer of the LCD and... voila - it was transparent. This capability has existed for decades (in fact all LCD displays are transparent - it's only the more modern OLED where that hasn't been the case) but there have always been backlights or some other material placed behind them to make them contrast as much as possible.
Better known as 318230.
Citations for any of this? I don't have one so what I'm saying is no more believable, but I do recall a study that showed HUDs were more of a hindrance than a help.
I don't have any citations, but I do have one car that has a HUD. In all honesty, I thought it would be a stupid gimmicky thing, but I wish every car I owned had one now. Granted, mine is fairly simple, but well designed. It displays a digital reading of speed as the largest item. There's a bar graph of the tach across the top, bar graph for fuel along the right side, oil pressure and turn signals. What I found surprising is that the road is not as far in my peripheral vision when I glance at the HUD vs. the instrument panel. Plus, for me at least, my eyes don't really need to refocus (or not as much) to see the speed on the HUD. The numbers are large enough for me to see them.
I saw something on /. a few months ago that mentioned that the amount of information on a HUD can become a big distraction after a certain point. So I can see how it would be a problem if turn by turn directions are up there and radio information, etc. I would think anytime you need to actually read words, or need to more than glance at something, it's going to be an issue.
