After a decade of hardware buttons that aren't, e.g. TV power buttons, I think for most people trust has sailed. It works if the company builds it's brand on it (Purism) but I would not trust a hardware switch from Lenovo or Dell.

Is dell as untrustworthy as lenovo? I do remember the lenovo driver that installed itself from the bios - even on a clean windows install - and would snoop for months and then silently uninstall itself. EDIT: here it is: https://en.wikipedia.org/wiki/Lenovo#Lenovo_Service_Engine However I have not heard much about dell.

Dell has an anti theft ‘solution’ that works the same as this, as do all the major vendors. The fault is with Microsoft for allowing that crap in the first place.

I think that’s a poor approach. While you end up with gaze more in the center of the display, you don’t always have a face directly centered. This alleviates some of the problem, but doesn’t remove it. A better approach that I’ve always wanted is to have four cameras on the corners of the display that generate a real time photogrametric projection of your face. This would mean not only would your camera view be dead…

It would be relatively trivial to automatically keep the face of the person you're talking to centered around the webcam using face detection. As a person moves in frame, your computer will "pan" to keep them centered. Four cameras is intriguing, but also expensive and complicated, and will probably have a very rough time with things like eyelashes, edges of hair, different patterns of reflections on the eyeballs, di…

Photogrammetry doesn't yet properly handle non-diffuse surfaces for the most part. There are some experiments, but they're way behind in other aspects.

And I'm not even talking real-time. So, yeah, uncanny valley or teleprompter it is.

I've owned a Dell XPS13 which was the crappiest product I've bought in a while. So I'd say the problem with Dell is more inablity vs. malicious intent.

What was so bad about it?

We've bought/had replaced half a dozen XPS13s in the last 18 months and all but one have had to be returned, some are on their second replacement. QA seems to be non-existent

Would this be useful for augmented-reality headsets?

Well, you get serious eye strain from focusing too close, so it would need optics to create a virtual image at a comfortable distance that your eyes can focus on.

In reality some lens(es) take the screen's light and bend it so that the angles of the light rays correspond to the light of a screen at that comfortable distance, but your eyes can't tell, just like they can't tell that the things are actually smaller when you look through a good pair of binoculars.

I'm excited for transparent OLED's simply so that laptops and monitors will be able to put the webcam behind the display, ~1/3 from the top. Then videoconferencing software can automatically move the image of the person you're talking to so their eyes are roughly centered on that point. And finally everyone gets to make direct eye contact again!

I think the OLEDs shipping in Samsung's phones are already transparent to a degree. They are able to put light sensor, proximity sensor and finger print sensor behind the screen. The can see through the screen. It's only a matter of time before they are able to put a full camera behind the display.

For a long long time, science fiction movies have used transparent displays to seem more "futuristic." However, actual transparent displays have been underwhelming in practice. This technology is being use by Xaomi to make a "transparent TV"[1] which in theory you will be able to buy. (I realize that not all of these sorts of announcements survive until actual product shipment). It will be interesting to see one of t…

Transparent OLEDs are not that new, they have been around for a while. See this Thermostat by Johnson COntrols.

Tangentially related, the "futuristic" displays in video games and movies and TV often look worse than what we'd see in real life. Sometimes it's a hologram, which would be cool even if the fidelity were a bit shit, but it's interesting that art directors make them pretty bad looking even in fiction, presumably as a cue to the viewer that it's a hologram. Any fiction that portrays holograms as opaque and convincing u…

I've heard, and the art director on the game followed the same philosophy, that art directors tend to make future tech look worse\glitchy on purpose so it's very clear to the audience that it's "tech". Technology that for all intents and purposes works mostly flawlessly looks a little too much like magic to audiences I guess? Like really you'd just want to have a person show up and look like they were there, but that…

I thought the Hologram technology in Blade Runner 2049 was pretty "flawless". The most interesting thing for that movie was that you see different levels of hologram technology.

The hologram that follows the main characters seems to be pretty high tech, and looks flawless. And they show the hologram stuff by having her move through objects.

But when the main characters walks around the city, you see hologram commercials that are the size of buildings. Those don't look lifelike. They're transparent and have limited colors.
