Benjamin Warf, a renowned neurosurgeon at Boston Children’s Hospital, stands in the MIT.nano Immersion Lab. More than 3,000 miles away, his virtual avatar stands next to Matheus Vasconcelos in Brazil as the resident practices delicate surgery on a doll-like model of a baby’s brain.

With a pair of virtual-reality goggles, Vasconcelos is able to watch Warf’s avatar demonstrate a brain surgery procedure before replicating the technique himself and while asking questions of Warf’s digital twin.

“It’s an almost out-of-body experience,” Warf says of watching his avatar interact with the residents. “Maybe it’s how it feels to have an identical twin?”

And that’s the goal: Warf’s digital twin bridged the distance, allowing him to be functionally in two places at once. “It was my first training using this model, and it had excellent performance,” says Vasconcelos, a neurosurgery resident at Santa Casa de São Paulo School of Medical Sciences in São Paulo, Brazil. “As a resident, I now feel more confident and comfortable applying the technique in a real patient under the guidance of a professor.”

Warf’s avatar arrived via a new project launched by medical simulator and augmented reality (AR) company EDUCSIM. The company is part of the 2023 cohort of START.nano, MIT.nano’s deep-tech accelerator that offers early-stage startups discounted access to MIT.nano’s laboratories.

In March 2023, Giselle Coelho, EDUCSIM’s scientific director and a pediatric neurosurgeon at Santa Casa de São Paulo and Sabará Children’s Hospital, began working with technical staff in the MIT.nano Immersion Lab to create Warf’s avatar. By November, the avatar was training future surgeons like Vasconcelos.

“I had this idea to create the avatar of Dr. Warf as a proof of concept, and asked, ‘What would be the place in the world where they are working on technologies like that?’” Coelho says. “Then I found MIT.nano.”

Capturing a Surgeon

As a neurosurgery resident, Coelho was so frustrated by the lack of practical training options for complex surgeries that she built her own model of a baby brain. The physical model contains all the structures of the brain and can even bleed, “simulating all the steps of a surgery, from incision to skin closure,” she says.

She soon found that simulators and virtual reality (VR) demonstrations reduced the learning curve for her own residents. Coelho launched EDUCSIM in 2017 to expand the variety and reach of the training for residents and experts looking to learn new techniques.

Those techniques include a procedure to treat infant hydrocephalus that was pioneered by Warf, the director of neonatal and congenital neurosurgery at Boston Children’s Hospital. Coelho had learned the technique directly from Warf and thought his avatar might be the way for surgeons who couldn’t travel to Boston to benefit from his expertise.

To create the avatar, Coelho worked with Talis Reks, the AR/VR/gaming/big data IT technologist in the Immersion Lab.

“A lot of technology and hardware can be very expensive for startups to access as they start their company journey,” Reks explains. “START.nano is one way of enabling them to utilize and afford the tools and technologies we have at MIT.nano’s Immersion Lab.”

Coelho and her colleagues needed high-fidelity and high-resolution motion-capture technology, volumetric video capture, and a range of other VR/AR technologies to capture Warf’s dexterous finger motions and facial expressions. Warf visited MIT.nano on several occasions to be digitally “captured,” including performing an operation on the physical baby model while wearing special gloves and clothing embedded with sensors.

“These technologies have mostly been used for entertainment or VFX [visual effects] or CGI [computer-generated imagery],” says Reks, “But this is a unique project, because we’re applying it now for real medical practice and real learning.”

One of the biggest challenges, Reks says, was helping to develop what Coelho calls “holoportation”— transmitting the 3D, volumetric video capture of Warf in real-time over the internet so that his avatar can appear in transcontinental medical training.

The Warf avatar has synchronous and asynchronous modes. The training that Vasconcelos received was in the asynchronous mode, where residents can observe the avatar’s demonstrations and ask it questions. The answers, delivered in a variety of languages, come from AI algorithms that draw from previous research and an extensive bank of questions and answers provided by Warf.

In the synchronous mode, Warf operates his avatar from a distance in real time, Coelho says. “He could walk around the room, he could talk to me, he could orient me. It’s amazing.”

Coelho, Warf, Reks, and other team members demonstrated a combination of the modes in a second session in late December. This demo consisted of volumetric live video capture between the Immersion Lab and Brazil, spatialized and visible in real-time through AR headsets. It significantly expanded upon the previous demo, which had only streamed volumetric data in one direction through a two-dimensional display.

Powerful impacts

Warf has a long history of training desperately needed pediatric neurosurgeons around the world, most recently through his nonprofit Neurokids. Remote and simulated training has been an increasingly large part of training since the pandemic, he says, although he doesn’t feel it will ever completely replace personal hands-on instruction and collaboration.

“But if in fact one day we could have avatars, like this one from Giselle, in remote places showing people how to do things and answering questions for them, without the cost of travel, without the time cost and so forth, I think it could be really powerful,” Warf says.

The avatar project is especially important for surgeons serving remote and underserved areas like the Amazon region of Brazil, Coelho says. “This is a way to give them the same level of education that they would get in other places, and the same opportunity to be in touch with Dr. Warf.”

One baby treated for hydrocephalus at a recent Amazon clinic had traveled by boat 30 hours for the surgery, according to Coelho.

Training surgeons with the avatar, she says, “can change reality for this baby and can change the future.”

Unsurprisingly, as the reigning World Cup champions, soccer is deeply embedded in Argentina's national identity. Players on the national team are praised as heroes by everyone, from die-hard fans to casual observers. Their trophies bring joy and a sense of triumph to a country that has seen much division and gloom in recent decades.

Sadly, recent victories could be the last blaze of a dying fire. Soccer (or as we call it, fútbol) in Argentina is in decline, exploited by nefarious interests—but President Javier Milei has a plan.

Until recently, domestic soccer clubs in Argentina had to be operated as nonprofits. An executive branch decree changed that, allowing clubs to become publicly traded companies. The change may spur lifesaving investment into Argentine soccer.

For fans of Argentina's national team and domestic league, this is good news.

Consider how many players are leaving Argentina to play elsewhere. In 2022, 5,000 Argentines were playing abroad, most of whom were promising players under the age of 20. Even among the 26 players on the World Cup-winning roster, only one came from a club in the Argentine league. The Argentine Football Association (AFA) is worried that players who start their careers overseas will choose not to represent their national team in international competitions. Even Lionel Messi, a dual national, was tempted to play for the Spanish national team before choosing to play for Argentina. AFA lives in constant fear of having a future world champion slip through their fingers.

What's causing this exodus of talent? While part of it is Argentina's general economic malaise, some, including Spanish La Liga President Javier Tebas, point a finger at AFA's narrow-minded refusal to allow private investment in the national soccer market. Tebas has said the Argentine team won the 2022 World Cup "despite AFA" because their players "were forged in European clubs."

Milei's reforms mean international companies could buy and sell teams, or invest in Argentina's striving clubs. An injection of foreign capital would be a boon not just to the clubs who'd be able to improve their capabilities and keep talented players at home, but also to the Argentine economy overall, as clubs expand and create more jobs with their newfound capital.

AFA leaders and some major teams denounced the reforms as a "privatization of football"—and if you know how the clubs currently work, it's easy to understand their resistance. 

In Argentina, soccer clubs are more than just sports teams. A club is like a church, a provider of all manner of cultural and educational services, a place for communities to share, for families to enroll their children and invest in their future—every young player's dream is to go pro and pay back his parents' sacrifice. While the clubs are already private nonprofits—an organizational model they're very defensive about—in reality, they are run by politicians, celebrities, and businessmen who use them to promote their public image. They keep governance opaque, convoluted, and unaccountable, cementing their power by making deals with barra bravas, powerful hooligan organizations that handle their illegal activities and intimidate opponents into silence—both within the clubs and in electoral politics.

Revenue from the domestic soccer league, such as TV rights money, is dispensed in a pyramid scheme with AFA President Claudio Tapia at the top, doling out favors to keep the clubs economically dependent. About 97 percent of clubs have, at some point, been on the brink of bankruptcy. This causes a vicious cycle: Teams in the league can't afford to keep promising players, who leave for foreign teams with deeper pockets, so the teams perform worse and earn less revenue.

In the late 1990s, Racing Club, one of the historic "Big Five" clubs, went bankrupt and was nearly liquidated. AFA authorized a special rescue plan that allowed insolvent clubs to contract private firms as management in exchange for financial salvage, copying previous experiences of successful entrepreneurial partnerships. Despite the plan's limited scope and the familiar cry of "veiled privatization," it performed so well that several clubs started contracting out their assets and are now faring consistently better than the rest. Meanwhile, fans remain involved by exercising oversight over contractors.

In a microcosm of national politics, mafiosos and oligarchs use populist rhetoric to entrench themselves in power, and then call the private sector to bail them out when reality catches up. In soccer, it's catching up again. Investment is still limited, the player pool is shrinking, clubs are chronically indebted and their services are becoming impoverished and exclusionary. Meanwhile, they're still run by a powerful few but lack transparency or efficiency. A country that's practically synonymous with fútbol should be attracting money and talent from all over the world, not scaring it away. A few conglomerates have expressed interest in Milei's reform, but he'll have to get past attempts at judicial obstruction and silencing of internal dissent by the AFA establishment.

Argentina is the birthplace of many stars in soccer history, but its clubs are suffering from economic stagnation. The private sector can help Argentines reclaim their clubs as social spaces and as points of national pride. Milei's reforms are an opportunity for soccer to become part of the nation's economic recovery. The profit motive, social ethics, and political will of those who love the sport can lead to even more glory.

Despite an authoritarian regime's efforts to obstruct free and fair elections, Venezuelans turned out in large numbers to vote for their president last Sunday, hoping for change amid widespread political repression and a humanitarian crisis. The U.S. is deeply implicated in this turmoil, as the disputed election results underscore significant geopolitical stakes and can have a significant impact on American interests.

A government-controlled electoral commission declared Nicolás Maduro the winner of the election, claiming he received 51 percent of the votes. Yet exit polls and tallies by the opposition indicate that over 70 percent of Venezuelans supported the opposition candidate, Edmundo González.

Governments around the world have denounced the election as fraudulent and demanded evidence of Maduro's claimed victory. Leaders such as Argentine President Javier Milei and Italian Prime Minister Giorgia Meloni have expressed their solidarity with the Venezuelan people's desire for change. 

U.S. Secretary of State Antony Blinken has echoed these concerns, claiming that the election results do not reflect the true will of the Venezuelan people. On Thursday, Blinken affirmed that the U.S. recognizes González as the legitimate winner of the Venezuelan elections.

Even left-wing governments like Brazil and Colombia are pressing Maduro to substantiate his claim of victory, but no such proof has emerged. In a bigger turn of events, the Carter Center, one of the few entities invited to observe the Venezuelan election, condemned the electoral commission for its lack of transparency. 

Protests erupted nationwide in response to the disputed election, with thousands taking to the streets. Several statues of former socialist president Hugo Chávez were toppled in the unrest. Clashes with security forces have resulted in hundreds of arrests and at least 17 deaths. 

Strategic Concerns for the U.S.

Supporting the democratic aspirations of Venezuelans is crucial for U.S. interests. A free Venezuela will address key U.S. policy concerns such as the rise in illegal migration, untapped market opportunities, the growing influence of Iran and China in the region, and security risks for international commerce in the region.

Should Maduro remain in power, migration to the United States from Venezuela is expected to surge. Surveys show that over 40 percent of Venezuelans plan to leave the country if Maduro continues as president. This potential influx of refugees could strain U.S. immigration systems and social infrastructure, posing a major humanitarian and logistical challenge.

American firms will also miss out on substantial business opportunities in Venezuela if Maduro stays in power. The country's vast reserves of oil and uranium represent untapped markets that could enhance U.S. energy security. Investing in Venezuela's oil industry could help diversify energy sources and reduce dependency on unstable or unfriendly regions, leading to more stable energy prices and a reliable supply of oil for the U.S. market. 

Maduro's continued rule will also likely increase the presence of U.S. adversaries such as Russia, Iran, and China in the region. Iran plans to expand trade with Venezuela to $20 billion per year, China is heavily investing in the country, and Russia has signed multiple military agreements with the South American country. As Venezuela continues to distance itself from the democratic world, one can only expect these relationships to strengthen. And having a rogue state relatively close to the U.S. border represents security concerns to American businesses and international trade in general. 

To address these challenges, American policy makers need to adopt a more strategic approach. The current administration has focused on negotiating sanction relief for the Maduro regime in exchange for promises to hold free and fair elections. But this has proven insufficient, producing no positive changes in Maduro's behavior.

A new foreign policy approach should include a reassessment of institutions such as the United Nations and the Organization of American States. For years, these institutions have systematically failed to uphold the rule of law and human rights in Venezuela. Additionally, U.S. policy makers should establish measures to prevent regimes from exploiting international treaties and cooperation agreements. This includes sectors like finance and energy, where regimes have undermined democratic nations' interests. Finally, the methodology and effectiveness of sanctions should be reassessed. Despite a series of sanctions imposed by the U.S. on countries like Venezuela, Russia, and Iran, the International Monetary Fund projects economic growth for all these nations in 2024.

Failure to address these issues risks empowering autocrats around the world, jeopardizing U.S. national security, economic performance, and diplomatic standing.

“I had this idea to create the avatar of Dr. Warf as a proof of concept, and asked, ‘What would be the place in the world where they are working on technologies like that?’” Coelho says. “Then I found MIT.nano.”

Capturing a Surgeon

As a neurosurgery resident, Coelho was so frustrated by the lack of practical training options for complex surgeries that she built her own model of a baby brain. The physical model contains all the structures of the brain and can even bleed, “simulating all the steps of a surgery, from incision to skin closure,” she says.

She soon found that simulators and virtual reality (VR) demonstrations reduced the learning curve for her own residents. Coelho launched EDUCSIM in 2017 to expand the variety and reach of the training for residents and experts looking to learn new techniques.

Those techniques include a procedure to treat infant hydrocephalus that was pioneered by Warf, the director of neonatal and congenital neurosurgery at Boston Children’s Hospital. Coelho had learned the technique directly from Warf and thought his avatar might be the way for surgeons who couldn’t travel to Boston to benefit from his expertise.

To create the avatar, Coelho worked with Talis Reks, the AR/VR/gaming/big data IT technologist in the Immersion Lab.

“A lot of technology and hardware can be very expensive for startups to access as they start their company journey,” Reks explains. “START.nano is one way of enabling them to utilize and afford the tools and technologies we have at MIT.nano’s Immersion Lab.”

Coelho and her colleagues needed high-fidelity and high-resolution motion-capture technology, volumetric video capture, and a range of other VR/AR technologies to capture Warf’s dexterous finger motions and facial expressions. Warf visited MIT.nano on several occasions to be digitally “captured,” including performing an operation on the physical baby model while wearing special gloves and clothing embedded with sensors.

“These technologies have mostly been used for entertainment or VFX [visual effects] or CGI [computer-generated imagery],” says Reks, “But this is a unique project, because we’re applying it now for real medical practice and real learning.”

One of the biggest challenges, Reks says, was helping to develop what Coelho calls “holoportation”— transmitting the 3D, volumetric video capture of Warf in real-time over the internet so that his avatar can appear in transcontinental medical training.

The Warf avatar has synchronous and asynchronous modes. The training that Vasconcelos received was in the asynchronous mode, where residents can observe the avatar’s demonstrations and ask it questions. The answers, delivered in a variety of languages, come from AI algorithms that draw from previous research and an extensive bank of questions and answers provided by Warf.

In the synchronous mode, Warf operates his avatar from a distance in real time, Coelho says. “He could walk around the room, he could talk to me, he could orient me. It’s amazing.”

Coelho, Warf, Reks, and other team members demonstrated a combination of the modes in a second session in late December. This demo consisted of volumetric live video capture between the Immersion Lab and Brazil, spatialized and visible in real-time through AR headsets. It significantly expanded upon the previous demo, which had only streamed volumetric data in one direction through a two-dimensional display.

Powerful impacts

Warf has a long history of training desperately needed pediatric neurosurgeons around the world, most recently through his nonprofit Neurokids. Remote and simulated training has been an increasingly large part of training since the pandemic, he says, although he doesn’t feel it will ever completely replace personal hands-on instruction and collaboration.

“But if in fact one day we could have avatars, like this one from Giselle, in remote places showing people how to do things and answering questions for them, without the cost of travel, without the time cost and so forth, I think it could be really powerful,” Warf says.

The avatar project is especially important for surgeons serving remote and underserved areas like the Amazon region of Brazil, Coelho says. “This is a way to give them the same level of education that they would get in other places, and the same opportunity to be in touch with Dr. Warf.”

One baby treated for hydrocephalus at a recent Amazon clinic had traveled by boat 30 hours for the surgery, according to Coelho.

Training surgeons with the avatar, she says, “can change reality for this baby and can change the future.”

Benjamin Warf, a renowned neurosurgeon at Boston Children’s Hospital, stands in the MIT.nano Immersion Lab. More than 3,000 miles away, his virtual avatar stands next to Matheus Vasconcelos in Brazil as the resident practices delicate surgery on a doll-like model of a baby’s brain.

With a pair of virtual-reality goggles, Vasconcelos is able to watch Warf’s avatar demonstrate a brain surgery procedure before replicating the technique himself and while asking questions of Warf’s digital twin.

“It’s an almost out-of-body experience,” Warf says of watching his avatar interact with the residents. “Maybe it’s how it feels to have an identical twin?”

And that’s the goal: Warf’s digital twin bridged the distance, allowing him to be functionally in two places at once. “It was my first training using this model, and it had excellent performance,” says Vasconcelos, a neurosurgery resident at Santa Casa de São Paulo School of Medical Sciences in São Paulo, Brazil. “As a resident, I now feel more confident and comfortable applying the technique in a real patient under the guidance of a professor.”

Warf’s avatar arrived via a new project launched by medical simulator and augmented reality (AR) company EDUCSIM. The company is part of the 2023 cohort of START.nano, MIT.nano’s deep-tech accelerator that offers early-stage startups discounted access to MIT.nano’s laboratories.

Argentine authorities are working with El Salvador, a pioneering nation in bitcoin adoption, aiming to boost cryptocurrency adoption in Argentina.

High-ranking officials from Argentina's National Securities Commission (CNV), the country's securities regulator, met with El Salvador's National Commission of Digital Assets on May 23 to discuss the use of cryptocurrencies, according to an official announcement by the CNV. The talks focused on El Salvador's experience in adopting bitcoin and its regulatory framework.

"El Salvador has emerged as one of the leading countries, not only in the use of bitcoin, but it has also stood out in the world of crypto assets. It has created a specific commission, the National Commission of Digital Assets (CNAD), and therefore has an experience that is very valuable for the CNV at this time," said Roberto E. Silva, president of the CNV.

Under President Nayib Bukele, El Salvador made history by becoming the first country to adopt bitcoin as legal tender in September 2021, using it alongside the U.S. dollar. At the same time, the country launched Chivo Wallet, a government-backed digital wallet, and gave $30 worth of bitcoin to citizens who signed up for it.

Since then, El Salvador has embarked on several ambitious projects to promote bitcoin use, including creating a bitcoin city powered by geothermal energy, issuing bitcoin bonds, and offering expedited citizenship to bitcoin investors.

To date, the country has mined 474 bitcoin and holds 5,756 bitcoin, valued at just under $400 million, according to a website that tracks El Salvador's bitcoin portfolio. Bukele has said he plans to keep growing El Salvador's holdings by buying one bitcoin every day.

In recent years, Argentina has also seen a surge in cryptocurrency adoption as its citizens seek refuge from the peso's depreciation and soaring inflation. And since Javier Milei became president of Argentina last year, the crypto sector has seen positive developments. Just a month after Milei took office, Minister of Foreign Affairs Diana Mondino legalized the use of bitcoin for settling contracts.

"We want to strengthen ties with the Republic of El Salvador, and therefore, we are going to explore the possibility of signing collaboration agreements with them," Silva said about the recent meeting. The meeting follows a visit in March by CNV Vice President Patricia Boedo to El Salvador to discuss regulatory issues, indicating the interest of both countries in reaching some kind of agreement on crypto assets.

News of this collaboration between the two countries sent ripples through the crypto market, pushing bitcoin's value past the $70,000 mark. A formal partnership between Argentina and El Salvador could signal a major shift in Latin America's approach to digital assets, paving the way for broader crypto adoption.

The answers, delivered in a variety of languages, come from AI algorithms that draw from previous research and an extensive bank of questions and answers provided by Warf.

In the synchronous mode, Warf operates his avatar from a distance in real time, Coelho says. “He could walk around the room, he could talk to me, he could orient me. It’s amazing.”

Coelho, Warf, Reks, and other team members demonstrated a combination of the modes in a second session in late December. This demo consisted of volumetric live video capture between the Immersion Lab and Brazil, spatialized and visible in real-time through AR headsets. It significantly expanded upon the previous demo, which had only streamed volumetric data in one direction through a two-dimensional display.

Powerful impacts

Warf has a long history of training desperately needed pediatric neurosurgeons around the world, most recently through his nonprofit Neurokids. Remote and simulated training has been an increasingly large part of training since the pandemic, he says, although he doesn’t feel it will ever completely replace personal hands-on instruction and collaboration.

“But if in fact one day we could have avatars, like this one from Giselle, in remote places showing people how to do things and answering questions for them, without the cost of travel, without the time cost and so forth, I think it could be really powerful,” Warf says.

The avatar project is especially important for surgeons serving remote and underserved areas like the Amazon region of Brazil, Coelho says. “This is a way to give them the same level of education that they would get in other places, and the same opportunity to be in touch with Dr. Warf.”

One baby treated for hydrocephalus at a recent Amazon clinic had traveled by boat 30 hours for the surgery, according to Coelho.

Training surgeons with the avatar, she says, “can change reality for this baby and can change the future.”

Benjamin Warf, a renowned neurosurgeon at Boston Children’s Hospital, stands in the MIT.nano Immersion Lab. More than 3,000 miles away, his virtual avatar stands next to Matheus Vasconcelos in Brazil as the resident practices delicate surgery on a doll-like model of a baby’s brain.

With a pair of virtual-reality goggles, Vasconcelos is able to watch Warf’s avatar demonstrate a brain surgery procedure before replicating the technique himself and while asking questions of Warf’s digital twin.

“It’s an almost out-of-body experience,” Warf says of watching his avatar interact with the residents. “Maybe it’s how it feels to have an identical twin?”

And that’s the goal: Warf’s digital twin bridged the distance, allowing him to be functionally in two places at once. “It was my first training using this model, and it had excellent performance,” says Vasconcelos, a neurosurgery resident at Santa Casa de São Paulo School of Medical Sciences in São Paulo, Brazil. “As a resident, I now feel more confident and comfortable applying the technique in a real patient under the guidance of a professor.”

Warf’s avatar arrived via a new project launched by medical simulator and augmented reality (AR) company EDUCSIM. The company is part of the 2023 cohort of START.nano, MIT.nano’s deep-tech accelerator that offers early-stage startups discounted access to MIT.nano’s laboratories.

In March 2023, Giselle Coelho, EDUCSIM’s scientific director and a pediatric neurosurgeon at Santa Casa de São Paulo and Sabará Children’s Hospital, began working with technical staff in the MIT.nano Immersion Lab to create Warf’s avatar. By November, the avatar was training future surgeons like Vasconcelos.

“I had this idea to create the avatar of Dr. Warf as a proof of concept, and asked, ‘What would be the place in the world where they are working on technologies like that?’” Coelho says. “Then I found MIT.nano.”

Capturing a Surgeon

As a neurosurgery resident, Coelho was so frustrated by the lack of practical training options for complex surgeries that she built her own model of a baby brain. The physical model contains all the structures of the brain and can even bleed, “simulating all the steps of a surgery, from incision to skin closure,” she says.

She soon found that simulators and virtual reality (VR) demonstrations reduced the learning curve for her own residents. Coelho launched EDUCSIM in 2017 to expand the variety and reach of the training for residents and experts looking to learn new techniques.

Those techniques include a procedure to treat infant hydrocephalus that was pioneered by Warf, the director of neonatal and congenital neurosurgery at Boston Children’s Hospital. Coelho had learned the technique directly from Warf and thought his avatar might be the way for surgeons who couldn’t travel to Boston to benefit from his expertise.

To create the avatar, Coelho worked with Talis Reks, the AR/VR/gaming/big data IT technologist in the Immersion Lab.

“A lot of technology and hardware can be very expensive for startups to access as they start their company journey,” Reks explains. “START.nano is one way of enabling them to utilize and afford the tools and technologies we have at MIT.nano’s Immersion Lab.”

Coelho and her colleagues needed high-fidelity and high-resolution motion-capture technology, volumetric video capture, and a range of other VR/AR technologies to capture Warf’s dexterous finger motions and facial expressions. Warf visited MIT.nano on several occasions to be digitally “captured,” including performing an operation on the physical baby model while wearing special gloves and clothing embedded with sensors.

“These technologies have mostly been used for entertainment or VFX [visual effects] or CGI [computer-generated imagery],” says Reks, “But this is a unique project, because we’re applying it now for real medical practice and real learning.”

One of the biggest challenges, Reks says, was helping to develop what Coelho calls “holoportation”— transmitting the 3D, volumetric video capture of Warf in real-time over the internet so that his avatar can appear in transcontinental medical training.
