Acer launches a compact SpatialLabs camera for 3D photos and videos

Acer has unveiled the new SpatialLabs Eyes Stereo Camera specifically for those who want to take 3D photos and videos. Users can not only use it to capture 3D content, but also to livestream in 3D on YouTube and other platforms, as well as to make 3D video calls on Teams, Zoom and Google Meet. The company describes the camera as "compact" and "pocket-sized," with dimensions measuring 4 x 2.6 x 0.9 inches.

It has a resolution of 8 megapixels per eye and a built-in selfie mirror encased in a weather-proof shell. The more casual users can take advantage of its Electronic Image Stabilization (EIS) feature, along with its auto and touch focus capabilities. But experienced photographers can customize their output as much as they want to in manual mode, which will allow them to adjust the camera's ISO, white balance and shutter speed settings. 

The camera's 3D livestreaming feature will be enabled by version 3.0 of Acer's SpatialLabs Player, while high-resolution 3D video conferencing will be made possible through the company's SpatialLabs video call widget. It will, of course, be compatible with Acer's range of SpatialLabs devices, including laptops with glasses-free 3D screens. But you can view 3D content captured by the device even on other companies' AR or VR headsets and 3D projectors. 

The Acer SpatialLabs Eyes Stereo Camera will be available in the third quarter of the year with prices starting at $549 or €549 in the US and in Europe, respectively.

Acer's new batch of Predator gaming monitors feature faster OLED screens

Acer has added three new gaming monitors to its Predator lineup, all of which have OLED displays and speedy refresh rates. The models — Predator X27U F3, Predator X34 X5 and Predator X32 X3 — work with NVIDIA's G-SYNC and AMD's FreeSync Premium Pro technologies to prevent tearing, stuttering, ghosting and input lags while you're gaming. They also feature true 10-bit color depth enhanced by a 99 percent coverage of the DCI-P3 color space, which means more color depths, higher contrasts and deeper blacks. The models come with stands with adjustable height that can tilt and swivel, and they're all equipped with two 5-watt speakers.

The Predator X27U F3 is a 27-inch monitor with a 2,560 x 1,440 pixel resolution and a 480 Hz refresh rate. It's outfitted with a USB-C and two HDMI 2.1 ports, and its stand has a tripod mount socket that can support streaming accessories like lights and cameras. The model will be available in the third quarter with prices starting at $1,200. 

Meanwhile, the Predator X32 X3 monitor is a 4K UHD OLED display with a refresh rate of 240 Hz, though you can get that up to 480 Hz if you don't mind gaming in Full HD resolution only. The 31.5-inch monitor also comes with one Type-C and two HDMI 2.1 ports, and it will be available in the fourth quarter of the year for $1,200 and above. 

Finally, the Predator X34 X5 has a 34-inch curved OLED screen with a 1800R curvature and a resolution of 3,440 x 1,440 pixels. It also has a 240 Hz refresh and a 0.03 ms response rate like the Predator X32 X3 model, though it doesn't seem like you can get a speedier refresh rate in exchange for lower resolution. The monitor has two HDMI 2.1 ports, a DisplayPort and USB Type-C port, and it will be available in the fourth quarter for at least $1,100.

Clock Mixes Analog, Digital, Retrograde Displays

Unique clocks are a mainstay around here, and while plenty are “human readable” without any instruction, there are a few that take a bit of practice before someone can glean the current time from them. Word clocks are perhaps on the easier side of non-traditional displays but at the other end are binary clocks or even things like QR code clocks. To get the best of both worlds, though, multiple clock faces can be combined into one large display like this clock build from [imitche3].

The clock is actually three clocks in one. The first was inspired by a binary clock originally found in a kit, which has separate binary “digits” for hour, minute, and second and retains the MAX 7219 LED controller driving the display. A standard analog clock rests at the top, and a third clock called a retrograde clock sits at the bottom with three voltmeters that read out the time in steps. Everything is controlled by an Arduino Nano with the reliable DS3231 keeping track of time. The case can be laser-cut or 3D printed and [imitche3] has provided schematics for both options.

As far as clocks builds go, we always appreciate something which can be used to tell the time without needing any legends, codes, or specialized knowledge. Of course, if you want to take a more complex or difficult clock face some of the ones we’re partial to are this QR code clock which needs a piece of hardware to tell the time that probably already has its own clock on it.

Google is putting more restrictions on AI Overviews after it told people to put glue on pizza

Liz Reid, the Head of Google Search, has admitted that the company's search engine has returned some "odd, inaccurate or unhelpful AI Overviews" after they rolled out to everyone in the US. The executive published an explanation for Google's more peculiar AI-generated responses in a blog post, where it also announced that the company has implemented safeguards that will help the new feature return more accurate and less meme-worthy results. 

Reid defended Google and pointed out that some of the more egregious AI Overview responses going around, such as claims that it's safe to leave dogs in cars, are fake. The viral screenshot showing the answer to "How many rocks should I eat?" is real, but she said that Google came up with an answer because a website published a satirical content tackling the topic. "Prior to these screenshots going viral, practically no one asked Google that question," she explained, so the company's AI linked to that website.

The Google VP also confirmed that AI Overview told people to use glue to get cheese to stick to pizza based on content taken from a forum. She said forums typically provide "authentic, first-hand information," but they could also lead to "less-than-helpful advice." The executive didn't mention the other viral AI Overview answers going around, but as The Washington Post reports, the technology also told users that Barack Obama was Muslim and that people should drink plenty of urine to help them pass a kidney stone. 

Reid said the company tested the feature extensively before launch, but "there’s nothing quite like having millions of people using the feature with many novel searches." Google was apparently able to determine patterns wherein its AI technology didn't get things right by looking at examples of its responses over the past couple of weeks. It has then put protections in place based on its observations, starting by tweaking its AI to be able to better detect humor and satire content. It has also updated its systems to limit the addition of user-generated replies in Overviews, such as social media and forum posts, which could give people misleading or even harmful advice. In addition, it has also "added triggering restrictions for queries where AI Overviews were not proving to be as helpful" and has stopped showing AI-generated replies for certain health topics.

Silent Hill 2 remake hits PS5 and PC on October 8

Bloober Team's remake of Silent Hill 2 is due to hit PlayStation 5 and PC on October 8, and it's looking nice and spooky. It's available to pre-order on Steam and via PlayStation.

It's been less than two years since Konami and Bloober Team announced the Silent Hill 2 remake, though news of its existence leaked a few months beforehand, giving fans plenty of time to catastrophize the entire situation. Today we got the first gameplay trailer for the remake, showcasing familiar hallways lined with bloody nurses, low-light environments crawling with bugs, and other nasty surprises that have always been lurking in the sleepy town of Silent Hill. With modern visuals, lighting and sensibilities, it all looks eerily beautiful.

Bloober Team is the studio behind the Layers of Fear franchise, Observer, Blair Witch and The Medium — all perfectly serviceable psychological horror experiences. Still, there's a lot to live up to here: Silent Hill 2 is a beloved, classic horror game. It hit the PlayStation 2 in 2001 and, more than 20 years on, plenty of fans are anxious to see how the remake will hold up. 

Bloober Team co-founder Piotr Babieno told Engadget in June 2023 that the studio shifted its entire game-making ethos for the Silent Hill 2 remake. Instead of leading with mood and set dressing, they made mechanics the foundation of the on-screen terror, using player input to generate disquiet. The Layers of Fear collection that came out last summer marked the end of Bloober Team's psychological-horror era.

“This year is like closing the era of making psychological horror games,” Babieno said last June. “Right now we are going into Bloober Team 3.0, making mass-market horror.” He continued, “We decided that our next titles should be much more mass-market oriented. We’d like to talk with more people. We’d like to deliver our ideas, with our DNA, not by environment or storytelling, but by action. So all of our future titles will have a lot of gameplay mechanics. They will be much bigger.”

2024 Business Card Contest: A Game for Two

If you want to make a good first impression on someone, it seems like the longer you can keep them talking, the better. After all, if they want to keep talking, that’s a pretty good sign that even if you don’t become business partners, you might end up friends. What better way to make an acquaintance than over a friendly game of tic-tac-toe?

This one will probably take them by surprise, being a 4×4 matrix rather than the usual 3×3, but that just makes it more interesting. The front of the card has all the usual details, and the back is a field of LEDs and micro switches. Instead of using X and O, [Edison Science Corner] is using colors — green for player one, and red for player two. Since playing requires the taking of turns, the microcontroller lights up green and red with alternating single-button presses.

Speaking of, the brains of this operation is an ATMega328P-AU programmed with Arduino. If you’d like to make your own tic-tac-toe business card, the schematic, BOM, and code are all available. Be sure to check out the build and demo video after the break.

Sony's Astro Bot is getting the Mario-like adventure it deserves

Sony’s lovable robo-mascot is getting a new game. During its PlayStation State of Play on Thursday, Sony dropped a trailer for the upcoming PS5 title Astro Bot. The 3D Mario-esque title, a sequel to the beloved pack-in, Astro’s Playroom, arrives on September 6.

The trailer sees our pal Astro wading through puddles full of pink flamingos, grappling across platforms like Bionic Commando and summoning a PS5 console to help fight a giant green alien in a UFO (as one tends to do). In a nod to old-school PlayStation, the trailer even includes a cameo from PaRappa the Rapper.

Sony describes Astro Bot as a “supersized adventure” that spans over six galaxies and 80 levels as you search for your lost crew. You’ll have over 15 new abilities, and, like in its predecessor, it will serve as a showcase for the various sensors and haptics in the DualSense controller.

Astro Bot will be available for pre-order on June 7 ahead of its September 6 release date.

OpenAI says it stopped multiple covert influence operations that abused its AI models

OpenAI said that it stopped five covert influence operations over the last three months that used its AI models for deceptive activities across the internet. These operations, which originated from Russia, China, Iran and Israel, attempted to manipulate public opinion and influence political outcomes without revealing their true identities or intentions, the company said on Thursday. “As of May 2024, these campaigns do not appear to have meaningfully increased their audience engagement or reach as a result of our services,” OpenAI said in a report about the operation, and added that it worked with people across the tech industry, civil society and governments to cut off these bad actors.

OpenAI’s report comes amidst concerns about the impact of generative AI on multiple elections around the world slated for this year including in the US. In its findings, OpenAI revealed how networks of people engaged in influence operations have used generative AI to generate text and images at much higher volumes than before, and fake engagement by using AI to generate fake comments on social media posts.

“Over the last year and a half there have been a lot of questions around what might happen if influence operations use generative AI,” Ben Nimmo, principal investigator on OpenAI’s Intelligence and Investigations team, told members of the media in a press briefing, according to Bloomberg. “With this report, we really want to start filling in some of the blanks.”

OpenAI said that the Russian operation, which it dubbed “Doppelganger”, used the company’s models to generate headlines, convert news articles to Facebook posts, and create comments in multiple languages to undermine support for Ukraine. Another Russian group used used OpenAI's models to debug code for a Telegram bot that posted short political comments in English and Russian, targeting Ukraine, Moldova, the US, and Baltic States. The Chinese network "Spamouflage," known for its influence efforts across Facebook and Instagram, utilized OpenAI's models to research social media activity and generate text-based content in multiple languages across various platforms. The Iranian "International Union of Virtual Media" also used AI to generate content in multiple languages.

OpenAI’s disclosure is similar to the ones that other tech companies make from time to time. On Wednesday, for instance, Meta released its latest report on coordinated inauthentic behavior detailing how an Israeli marketing firm had used fake Facebook accounts to run an influence campaign on its platform that targeted people in the US and Canada.
