Moving Towards Glasses-Free 3D Videoconferencing with Project Starline

0

The first commercial 3D cinema experiences date back more than a century, with the film The Power of Love shown in Los Angeles in 1920. Back then, stereoscopic glasses were already being used to achieve the effect. Today, when we talk about metaverses and mixed reality, it is still necessary to use some glasses to achieve the three-dimensional effect. Unless, of course, Google gets its way and succeeds in making its new glasses-free 3D video conferencing system standard. Enter Project Starline.

In this article, you will read about:

How Starline 3D videoconferencing works

Mainly due to remote work, videoconferencing has become increasingly popular in recent years. The problem is that the 2D visualization of current systems generates cognitive dissonance in the user, the so-called “Zoom fatigue.” Hence, research is being made into other options.

The Starline 3D telepresence project was introduced in 2021, although at that time, an entire booth was required for the user to enjoy the effect. In that first model, a series of infrared cameras and other sensors were used to analyze the speaker’s image and then translate it onto a 3D screen using a light field system. Starline’s basic technology consists of these three phases:

  1. Capturing and 3D mapping of the interlocutor
  2. Compression of data for transmission over networks
  3. 3D monitor display

Of course, installing a booth in a work environment was not a realistic alternative to the current video conferencing, regardless of the 3D perks. Finally, in early 2023, Google announced that it had improved its system so much that it had dispensed with most of the sensors used in the first Starline prototype. According to the developers, using several standard cameras and artificial intelligence software suffices to offer glasses-free 3D video conferencing.

At first glance, the new version of the Project Starline is a simple screen, similar to that of an LED TV, which is equipped with three sensors on the sides and top strip, respectively. It is a working prototype that Google has distributed to partners such as T-Mobile, Salesforce, and WeWork for real-world testing.

Main advantages of 3D videoconferencing

As mentioned, 2D videoconferencing can create fatigue due to the lack of connection to real space. In addition, using virtual or augmented reality glasses for long periods still causes some discomfort due to the weight of the devices and, in some cases, dizziness due to latency issues, i.e., the speed of reaction between what is seen and what is happening.

New 3D videoconferencing systems like Project Starline are expected to improve productivity in professional environments and, more importantly, the human connection between call participants.

Glasses-free 3D video conferencing alternatives

Of course, Google is not the only developer interested in this field. One of the alternatives to Project Starline is the approach of a U.S. company that has designed a booth where the speaker can be shown in full body. It is enough to record the person with a white background and a basic camera – the company indicates that a cell phone can be used – and then transmit the data to the booth, which consists of a 4K screen two and a half meters high and can be installed in any space, be it an office, a shopping mall or an airport.

The developer describes this concept as “holoportation.” Artificial intelligence makes it possible to generate a sensation of depth when looking at the screen. The main drawback of the technology at the moment is that the full-size unit costs seventy-five thousand dollars, which rules it out as a device for everyday use.  

In addition to the technologies above, there are other somewhat less expensive alternatives to improve the usability of videoconferences. One of them transfers the images of the participants to a realistically rendered 3D space so that all of them are integrated into it as if it were a conference room. You can see how it works in this video.

Russia-Ukraine War: Recap of Important Events on Day 1,257 | Latest Updates on Russia-Ukraine Conflict

0

Here is how things stand on Monday, August 4:

Fighting

  • A Russian attack killed three people in Ukraine’s southeastern Zaporizhia region on Sunday, Governor Ivan Fedorov wrote on Telegram.
  • A Ukrainian drone attack sparked a major fire at an oil depot in Sochi in southern Russia, the governor of Russia’s Krasnodar region, Veniamin Kondratiev, said on Sunday. The fire was extinguished hours later after 120 firefighters were deployed, officials said. Russia’s civil aviation authority, Rosaviatsia, briefly halted flights at Sochi’s airport during the fire.
  • Ukraine’s military says it used drones to target several sites inside Russia, including refineries, an airfield and an electronics plant.
  • The governor of the Voronezh region in southern Russia said four people were injured in a Ukrainian drone attack that caused several fires,
  • A Russian attack injured seven people and destroyed dozens of houses and apartments in the southern Ukrainian city of Mykolaiv, Mayor Oleksandr Senkevych said on Telegram early on Sunday.
  • The Ukrainian air force said on Sunday that Russia launched 76 drones and seven missiles against Ukraine. It said 60 drones and one missile were intercepted, but 16 drones and six missiles hit eight different locations across Ukraine.
  • The Russian Ministry of Defence said its air defence units destroyed 93 Ukrainian drones overnight, including one over the Krasnodar region and 60 over the waters of the Black Sea. It did not specify how many drones were fired in total.

Politics and Diplomacy

  • Ukrainian President Volodymyr Zelenskyy announced that Ukraine and Russia have agreed to exchange 1,200 prisoners following negotiations in Istanbul, adding that “work on the lists [of prisoners to be released] is ongoing”. There was no immediate comment from Russia.
  • Zelenskyy announced he had appointed Anatolii Kryvonozhko as Commander of Ukraine’s air force, a role Kryvonozhko has been serving in as Acting Commander for nearly a year.
  • Zelenskyy also said that Ukraine has prepared three new sanctions packages, including sanctions against the captains of Russia’s shadow fleet of oil tankers.
  • China and Russia began joint naval drills in the Sea of Japan in waters near the Russian port of Vladivostok, China’s Ministry of National Defence said in a statement on Sunday. The drills will last for three days.
  • Speaking to a crowd of one million young Catholics on the outskirts of Rome, Pope Leo said: “We are with the young people of Gaza; we are with the young people of Ukraine.”

Today’s stock market: Dow futures fall as recession concerns grow

0

Markets were pointing toward another selloff Sunday evening after startling jobs data delivered a rude awakening to Wall Street bulls.

Futures tied to the Dow Jones Industrial Average fell 47 points, or 0.11%. S&P 500 futures were down 0.17%, and Nasdaq futures slipped 0.23%.

The yield on the 10-year Treasury was flat at 4.216% after plunging Friday on greater expectations for Fed rate cuts. The U.S. dollar was steady against the euro and down 0.09% against the yen.

Gold rose 0.44% to $3,414.10 per ounce. U.S. oil prices dropped 0.67% to $66.88 per barrel, and Brent crude fell 0.72% to $69.17, as OPEC+ announced another surge in production.

After investors marveled at how resilient the economy appeared in the face of President Donald Trump’s tariffs, it turns out conditions were actually much weaker, with job gains over the last three months averaging just 35,000.

Combined with separate indicators showing deterioration in consumer spending, housing, and manufacturing, the overall picture is one of an economy “on the precipice of recession,” according to Mark Zandi from Moody’s Analytics. That followed a similar warning from economists at JPMorgan.

Others had previously sounded the alarm on glaring red flags. But in the days leading up to the jobs report, some top commentators were still trying to explain why doomsday predictions about Trump’s “Liberation Day” tariffs had yet to materialize.

On Thursday, former White House economic adviser Jason Furman attributed it in part to “tariff derangement syndrome.” And last Sunday, Rockefeller International Chair Ruchir Sharma said the negative effects of tariffs were likely being offset by other factors like the AI spending splurge and lower inflationary pressure from housing, cars and energy.

With Wall Street now more attuned to economic risks like Trump’s trade war, the tariffs that will go into effect on Thursday may get more scrutiny. That includes steeper duties on trading partners like Canada and Switzerland.

Meanwhile, the calendar of economic reports thins out in the coming week after several big ones last week. On Tuesday, the trade deficit for June comes out, providing an update on how much tariffs are impacting imports. On Thursday, second-quarter productivity is due.

Earnings season has passed its peak, but several top names will issue quarterly reports. Palantir Technologies reports Monday after securing a $10 billion software and data contract from the Army.

Chip giant Advanced Micro Devices will report on Tuesday—potentially offering hints at Nvidia’s results, which don’t come out until Aug. 27.

Other companies scheduled to release earnings in the coming week include Caterpillar, Disney, and McDonald’s. It will also be a busy time for pharmaceutical and biotech giants like Amgen, Pfizer, and Eli Lilly as Trump weighs steep tariffs on drugs.

Rescuers in Chile discover the body of the final trapped miner

0

Rescuers in Chile have found the body of the last of five workers who had been trapped in the world’s largest underground copper mine after an earthquake on Thursday.

The announcement was made by regional prosecutor Aquiles Cubillos, who said the focus now was on a criminal investigation into the incident at El Teniente mine, run by the state-owned Codelco company.

The four other bodies had been discovered on Saturday and earlier on Sunday during a desperate search in collapsed mine tunnels, about 70km (43 miles) south-east of the capital Santiago.

The overall death toll is now confirmed at six, as another person was killed at the time of the incident on Thursday.

The collapse of some of the tunnels was caused by a 4.2 magnitude tremor on Thursday. Miners had been working deep below the surface.

Codelco has so far named two of the victims – Paulo Marín and Gonzalo Núñez Caroca – but said the others were yet to be identified “by the relevant authorities”.

“We share the anguish this situation causes their families and the entire community,” the copper mining company said.

Rescue teams had been using heavy machinery in an effort to clear the blocked passageways to try to reach the miners.

Codelco said rescue teams had cleared 24m (78.7ft) of blocked passages at the mine.

El Teniente is located high in the Andes mountains in central Chile.

Authorities have said they are investigating whether the cause of the earthquake was mining activity or natural tectonic shifts.

US District Judge rejects Shira Perlmutter’s request for preliminary injunction in Copyright Office dispute

0

A federal judge has denied former Register of Copyrights Shira Perlmutter’s motion for a preliminary injunction that would have restored her to her position while challenging her removal by the Trump administration.

US District Judge Timothy Kelly ruled on Wednesday (July 30) that Perlmutter failed to demonstrate irreparable harm warranting emergency relief.

Perlmutter filed her lawsuit in May, claiming her dismissal was “unlawful and ineffective” after President Trump fired both her and Librarian of Congress Carla Hayden via email.

The administration appointed Deputy Attorney General Todd Blanche as acting Librarian of Congress, who subsequently named Paul Perkins as acting Register of Copyrights.

In his memorandum opinion, Judge Kelly wrote that “the Court’s analysis begins and ends with irreparable harm,” explaining that Perlmutter failed to convince the court that she, the Library of Congress, or the Copyright Office faces irreparable damage from her temporary removal.

The judge noted that the Copyright Office can continue operating under Perkins’ leadership regardless of whether Perlmutter is ultimately reinstated.

“Perlmutter has not shown that the existence of the Copyright Office is at stake, or that her position will likely be irreparably changed without an injunction,” Kelly stated. “Yet again, Perlmutter has not shown that the Copyright Office will grind to a halt without her.”

The ruling represents the second setback for Perlmutter’s legal challenge, following the court’s denial of her temporary restraining order request in May. Judge Kelly had previously indicated skepticism about Perlmutter’s ability to meet the irreparable harm standard required for emergency injunctive relief.

Perlmutter promptly filed notice of appeal to the US Court of Appeals for the District of Columbia Circuit on Thursday (August 1), signaling her intention to continue the legal battle. The appeal comes as the Copyright Office faces questions about leadership continuity, particularly regarding its ongoing artificial intelligence report that Perlmutter had highlighted as urgent work requiring her oversight.

The dispute has broader implications for the music industry, given the Copyright Office’s role in regulating performance rights organizations and overseeing mechanical licensing through entities like The Mechanical Licensing Collective.

The office also plays a crucial role in AI-related copyright policy, an increasingly important area for music rights holders.

Perlmutter’s removal occurred shortly after the Copyright Office published the third installment of its comprehensive report on copyright and artificial intelligence, examining the use of copyrighted works in training generative AI systems. The timing raised questions about potential policy motivations behind the leadership changes.

The case centers on the legal authority to remove the Register of Copyrights, with Perlmutter arguing that Trump lacked the power to dismiss her directly. The administration maintains that the removal was lawful under existing federal statutes.

While the preliminary injunction denial keeps Perlmutter out of office for now, the underlying merits of her lawsuit remain to be decided. The appeal process could extend the legal proceedings for months, potentially overlapping with any decisions about permanent appointments to lead the Library of Congress and Copyright Office.

Boat sinking off Yemeni coast claims lives of over 50 refugees and migrants

0

DEVELOPING STORY,

Rescue operations are ongoing to find dozens more missing, local authorities say.

At least 54 African refugees and migrants have died and dozens remain missing after a boat capsized off the coast of Yemen, according to health authorities in Abyan governorate in the south of the country.

Abdul Qader Bajamil, director of the health office in Zanzibar, said on Sunday that rescue teams had recovered 54 bodies from the beaches there and surrounding areas, while 12 survivors were transferred to Shaqra Hospital.

The boat carrying around 150 people, mostly from Ethiopia, capsized in the Arabian Sea off the coast of Shaqra, in the Abyan governorate, due to strong winds on Saturday evening.

Bajamil noted that authorities were making arrangements to bury the victims in an area near the city, while search operations continued amid difficult conditions.

The waterways between Yemen and the Horn of Africa are a common but perilous route for refugees and migrants travelling in both directions. The area saw a spike in Yemenis fleeing the country after the civil war broke out in 2014.

Houthi rebels and government forces reached a truce deal in April 2022 that has resulted in a decrease in violence and the slight easing of the ongoing humanitarian crisis in Yemen.

Meanwhile, some of those fleeing conflict in Africa, particularly in Somalia and Ethiopia, have sought refuge in Yemen or have sought to travel through the country to the more prosperous Gulf countries. The route remains one of the “busiest and most perilous” migration routes in the world, according to the United Nations’ International Organization for Migration (IOM).

To reach Yemen, people are taken by smugglers on often dangerous, overcrowded boats across the Red Sea or the Gulf of Aden.

According to the IOM, more than 60,000 refugees and migrants arrived in Yemen in 2024, marking a significant drop from the previous year’s total of 97,200.

The decreased numbers come amid increased patrols of the waters, according to an IOM report released in May.

This is a deadly route that has killed hundreds over the past two years. According to the IOM, 558 people died along the route last year.

Over the past decade, at least 2,082 people have disappeared along the route, including 693 known to have drowned, according to the IOM. Yemen currently houses around 380,000 refugees and migrants.

Summer McIntosh Opts Out of 2026 Commonwealth Games to Concentrate on 2026 Pan Pacs

0

By Anya Pelshaw on SwimSwam

Canadian superstar Summer McIntosh will skip the 2026 Commonwealth Games, according to The Sydney Morning Herald. She instead will focus on the 2026 Pan Pac Games.

The 2026 Commonwealth Games are scheduled for July 23-August 2 in Glasgow, Scotland. This is just ten days before the 2026 Pan Pacific Championships begin in Irvine, California on August 12 and run through August 15. Glasgow is eight hours ahead of Irvine, so the time change would have been one obstacle.

McIntosh did swim at the 2022 edition of the Commonwealth Games in Birmingham, England when she was 15 years old. There she swam to gold medals in the 200 IM and 400 IM, setting World Junior records in the process. She also swam to a silver medal in the 400 free, finishing behind Australia’s Ariarne Titmus.

Not only will McIntosh impact Canada’s medal table at the individual level but her absence takes a hit on relays as well. She helped the team to silver medals in the 4×200 free relay and 4×100 medley relay while the 4×100 free relay earned bronze.

Pan Pacs in Irvine will mark McIntosh’s debut at the Pan Pac Championships as the last edition of the meet was in 2018, when McIntosh was just 11 years old.

This past week at the 2025 World Championships, McIntosh swam to four gold medals, winning the 400 free, 200 IM, 400 IM, and 200 butterfly. She also won bronze in the 800 freestyle.

McIntosh is set to change her training base as she will join Bob Bowman in Austin, Texas later this month. Austin is only two hours ahead of Irvine, California. It also is just over a three hour plane ride to get from Austin to Los Angeles, much closer than the trip from Austin to Glasgow.
