Computer scientists at Princeton are working to bring virtual reality into the physical world, with the potential to enhance a variety of experiences, including remote collaboration, education, entertainment and gaming.

Someday virtual and augmented reality technology will likely be commonplace, said Parastoo Abtahi, assistant professor of computer science. It will be important that users of this technology are able to seamlessly interact with the physical world.

Abtahi and postdoctoral research associate Mohamed Kari are working to make this possible by pairing technology with a physical robot that the user can control. Their research will be presented next month at the ACM Symposium on User Interface Software and Technology in Busan, Korea.

Someone using this system can, while wearing a mixed reality headset, select a drink from a list of options and then place it, virtually, on the desk in front of them. Or, more fantastically, they can ask an animated bee to deliver a bag of chips to them on the sofa.

At first, the drink and the chips might be only pixels. But after a minute or so, they will physically materialize, as if by magic. But it’s not magic—it’s a robot, rendered invisible to the user, that has delivered the snack. “Visually, it feels instantaneous,” said Abtahi.

By removing “all unnecessary technical details, even the robot itself,” said Kari, the experience appears seamless. The goal is to make the technology disappear and have the interaction between human and computer feel intuitive.

A key technical challenge in this system is communication. The user must be able to communicate their desires simply—selecting a pen across the room, for example, and moving it to the table in front of them. Kari and Abtahi created an interaction technique where a simple hand gesture allows the user to select an object, even from far away.

These gestures are then translated into commands for the robot to execute. The robot is outfitted with its own mixed reality headset, so it knows where to place objects within the .

Another is adding and erasing from the user’s field of view. Using a technology called 3D Gaussian splatting, Abtahi and Kari create a realistic digital copy of the physical space. Once everything in the room has been scanned, it allows the system to erase something from view, like a moving robot, or add something, like an animated bee.

To achieve this, every inch of the room and every object within it must be scanned and rendered digitally. Right now, the process is somewhat tedious, said Abtahi. Streamlining it, perhaps by assigning the task to a , is a subject for future in her lab.

Meta’s Layoffs Leave Supernatural Fitness Users in Mourning

Meta’s Layoffs Leave Supernatural Fitness Users in Mourning


Tencia Benavidez, a Supernatural user who lives in New Mexico, started her VR workouts during the Covid pandemic. She has been a regular user in the five years since, calling the ability to workout in VR ideal, given that she lives in a rural area where it’s hard to get to a gym or workout outside during a brutal winter. She stuck with Supernatural because of the community and the eagerness of Supernatural’s coaches.

“They seem like really authentic individuals that were not talking down to you,” Benavidez says. “There’s just something really special about those coaches.”

Meta bought Supernatural in 2022, folding it into its then-heavily invested in metaverse efforts. The purchase was not a smooth process, as it triggered a lengthy legal battle in which the US Federal Trade Commission tried to block Meta from purchasing the service due to antitrust concerns about Meta “trying to buy its way to the top” of the VR market. Meta ultimately prevailed. At the time, some Supernatural users were cautiously optimistic, hoping that big bag of Zuckerbucks could keep its workout juggernaut afloat.

“Meta fought the government to buy this thing,” Benavidez says. “All that just for them to shut it down? What was the point?”

I reached out to Meta and Supernatural, and neither responded to my requests for comment.

Waking Up to Ash and Dust

On Tuesday, Bloomberg reported that Meta has laid off more than 1,000 people across its VR and metaverse efforts. The move comes after years of the company hemorrhaging billions of dollars on its metaverse products. In addition to laying off most of the staff at Supernatural, Meta has shut down three internal VR studios that made games like Resident Evil 4 and Deadpool VR.

“If it was a bottom line thing, I think they could have charged more money,” Goff Johnson says about Supernatural. “I think people would have paid for it. This just seems unnecessarily heartless.”

There is a split in the community about who will stay and continue to pay the subscription fee, and who will leave. Supernatural still has more than 3,000 lessons available in the service, so while new content won’t be added, some feel there is plenty of content left in the library. Other users worry about how Supernatural will continue to license music from big-name bands.

“Supernatural is amazing, but I am canceling it because of this,” Chip told me. “The library is large, so there’s enough to keep you busy, but not for the same price.”

There are other VR workout experiences like FitXR or even the VR staple Beat Saber, which Supernatural cribs a lot of design concepts from. Still, they don’t hit the same bar for many of the Supernatural faithful.

“I’m going to stick it out until they turn the lights out on us,” says Stefanie Wong, a Bay Area accountant who has used Supernatural since shortly after the pandemic and has organized and attended meetup events. “It’s not the app. It’s the community and it’s the coaches that we really, really care about.”

Welcome to the New Age

I tried out Supernatural’s Together feature on Wednesday, the day after the layoffs. It’s where I met Chip and Alisa. When we could stop to catch our breath, we talked about the changes coming to the service. They had played through previous sessions hosted by Jane Fonda or playlists with a mix of music that would change regularly. It seems the final collaboration in Supernatural’s multiplayer mode will be what we played now, an artist series featuring entirely Imagine Dragons songs.

In the session, as we punched blocks while being serenaded by this shirtless dude crooning, recorded narrations from Supernatural coach Dwana Olsen chimed in to hype us up.

“Take advantage of these moments,” Olsen said as we punched away. “Use these movements to remind you of how much awesome life you have yet to live.”

Frankly, it was downright invigorating. And bittersweet. We ended another round, sweaty, huffing and puffing. Chip, Alisa, and I high-fived like crazy and readied for another round.

“Beautiful,” Alisa said. “It’s just beautiful, isn’t it?”

PSNI resorted to pen and paper after issues with ControlWorks command and control software | Computer Weekly

PSNI resorted to pen and paper after issues with ControlWorks command and control software | Computer Weekly


Unexpected problems in the Police Service of Northern Ireland’s (PSNI’s) ControlWorks software led to police having to resort to manual forms to record calls from the public soon after the software’s introduction in 2019, Computer Weekly has learned.

The force has not reported the incidents to the Northern Ireland Policing Board, which oversees the PSNI, and has not mentioned any incidents with ControlWorks in its annual reports.

While there is no legal duty to report failures with ControlWorks to the Northern Ireland Policing Board, the Policing Board has told Computer Weekly it would expect any serious incidents with ControlWorks to be reported to it.

The PSNI uses ControlWorks as part of its command and control system, for managing, logging and categorising calls received by the emergency services from the public and for dispatching police officers to incidents.

Computer Weekly has learned that the PNSI’s ControlWorks system had technical issues after it first went live in May 2019.

These included slow-downs of the system that required computer systems to be restarted or software to be patched.

On some occasions, police were forced to return to using paper forms to record incidents reported by the public after ControlWorks became unavailable. Information on the forms had to be typed back into the system when the service resumed.

ControlWorks aimed to improve response times

The PSNI announced it was using Capita Communications and Control Solutions’ ControlWorks software in 2018, replacing its 20-year-old Capita Atlas Command and Control System, which had reached the end of its life.

From February 2018, ControlWorks was installed across the PSNI’s three regional contact management centres, before going live in May 2019, but is understood to have had a series of issues during its first few months of operation.

Critical incidents, which affect force-wide availability of ControlWorks, are categorised as P1 or P2. Less serious incidents that do not require urgent remediation are categorised as P3 and P4, Computer Weekly has previously reported.

Computer Weekly understands that the PSNI runs a 24-hour help desk to deal with IT issues, and that it has the ability to escalate incidents with ControlWorks to its IT supplier.

Missing persons search

Computer Weekly understands that a “major issue” with ControlWorks may have delayed information being passed to police officers searching for missing teenager Noah Donohoe, who disappeared from his home in Belfast on 21 June 2020.

Donohoe’s disappearance sparked a massive search operation, as police reviewed hours of CCTV, and hundreds of volunteers joined the search for the vulnerable 14-year-old.

Computer Weekly has learned that on the evening of 23 June 2020, police recorded a “major issue” with ControlWorks that could have led to delays in information being passed to investigators.

Computer Weekly further understands that on the evening of 24 June, a member of the public called police to say they had seen an individual attempting to sell Donohoe’s missing laptop.

This potentially critical information was delayed in being brought to the attention of police officers investigating Donohoe’s disappearance  because of a problem with ControlWorks, Computer Weekly has been told.

It is unclear exactly how long the information was delayed by and what its impact on the search for the missing teenager was. But it is understood that detectives on the case reported and noted the delay during the investigation.

The issue with ControlWorks was understood to have been reported during the live investigation at a critical time when Donohoe was missing – two days after he had gone missing, and four days before he was found dead in a Belfast storm drain.

Manchester had serious IT issues

Greater Manchester Police experienced problems when it went live with its Integrated Operational Policing System (iOPS), which included ControlWorks, in July 2019. iOps attempted to integrate Capita’s ControlWorks software with Capita’s PoliceWorks record management software used by police officers for managing day-to-day investigations and intelligence records.

An independent review found serious issues with the project. At one point, police were forced to revert to pen and paper for 72 hours while records were migrated to the new system.

“This consumed considerable time and capacity, causing a duplication of work,” the report found. “In addition, some legacy demand, which included ongoing investigations, did not successfully transfer from the old systems, so could no longer be worked on.”

Greater Manchester Police subsequently announced plans to replace PoliceWorks after concluding it could not be adapted or fixed, but it has continued to use ControlWorks.

The PSNI uses a different record management system to Manchester’s troubled PoliceWorks system. The PSNI signed a £9m contract with the Canadian company NicheRMS to deploy its Records Management System, which records information about people, locations, vehicles, incidents and evidence, in 2006.

NicheRMS keeps duplicate records of reports from the public that are recorded on ControlWorks when they are escalated as an “incident”. This means that should data be lost because of problems with ControlWorks, the PSNI would still have access to duplicate records reported by the public on NicheRMS if they have been escalated as an “incident”.

Policing Board seeks clarification from PSNI

The Northern Ireland Policing Board has confirmed that if a major system disruption or significant information or data loss occurred, the board would expect to be informed.

A spokesperson told Computer Weekly that the board’s Resources Committee, which has oversight responsibility for matters including the PSNI’s technology systems, has asked the PSNI for clarification about the issues raised by Computer Weekly.

A coroner’s inquest into the circumstances of Noah Donohoe’s death is due to begin on 19 January.

The PSNI said it would “not comment on investigative matters while legal proceedings are ongoing”.

“With regards to questions relating to ControlWorks, police can confirm that, to date, there has been no instance of major disruption which has led to data loss,” a spokesperson said.

Capita declined to comment.

Cyber body ISC2 signs on as UK software security ambassador | Computer Weekly


ISC2, the non-profit cyber professional membership association, has joined the UK government’s recently launched Software Security Ambassador Scheme as an expert adviser.

Set up at the beginning of the year by the National Cyber Security Centre (NCSC) and the Department for Science, Innovation and Technology (DSIT), the scheme forms part of a wider £210m commitment by Westminster to remodel approaches to public sector cyber resilience from the ground up, acknowledging that previous approaches to the issue have basically gone nowhere and that previously set targets for resilience are unachievable.

It is designed to incentivise organisations to pay more attention to the security of software products, and supports the wider adoption of the Software Security Code of Practice, a set of voluntary principles defining what secure software looks like.

ISC2 joins a number of tech suppliers, including Cisco, Palo Alto Networks and Sage; consultancies and service providers including Accenture and NCC Group; and financial services firms including Lloyds Banking Group and Santander. Fellow cyber association ISACA is also involved.

“Promoting secure software practices that strengthen the resilience of systems underpinning the economy, public services and national infrastructure is central to ISC2’s mission,” said ISC2’s executive vice-president for advocacy and strategic engagement, Tara Wisniewski.

“The code moves software security beyond narrow compliance and elevates it to a board-level resilience priority. As supply chain attacks continue to grow in scale and impact, a shared baseline is essential and through our global community and expertise, ISC2 is committed to helping professionals build the skills needed to put secure-by-design principles into practice,” she said.

Software vulns a huge barrier to resilience

A study of wider supply chain risks conducted last year by ISC2 found that a little over half of organisations worldwide reported that vulnerabilities in their software suppliers’ products represented the most disruptive cyber security threat to their overall supply chain.

And the World Economic Forum’s (WEF’s) Global Cybersecurity Outlook report, published on 12 January, revealed that third-party and supply chain vulnerabilities were seen as a huge barrier to building cyber resilience by C-suite executives.

A total of 65% of respondents to the WEF’s annual poll flagged such flaws as the greatest challenge their organisation faced on its pathway to resilience, compared to 54% at the beginning of 2025. This outpaced factors such as the evolving threat landscape and emerging AI technology, use of legacy IT systems, regulatory compliance and governance, and cyber skills shortages.

Pressed on the top supply chain cyber risks, respondents were most concerned about their ability to assure the integrity of software and other IT services, ahead of a lack of visibility into their supplier’s supply chains and overdependence on critical third-party suppliers.

The UK’s Code of Practice seeks to answer this challenge by establishing expectations and best practices for tech providers and any other organisations that either develop, sell or buy software products. It covers aspects such as secure design and development, the security of build environments, deployment and ongoing upkeep, and transparent communication with customers and users.

As part of its role as an ambassador, ISC2 will assist in developing and improving the Code of Practice, while championing it by embedding its guiding principles into its own cyber education and professional development services – the organisation boasts 10,000 UK members and associates. 

It will also help to drive adoption of the Code of Practice through various awareness campaigns, incorporating it into its certifications, training and guidance, engaging with industry stakeholders and members to encourage implementation, and incorporating its provisions into its work with its own commercial suppliers.
