These Robotic Cats Feature Glowing Eyes and Heartbeat Technology, Offering Stress Relief for Children

At the Springwood Library in the Blue Mountains, librarians arrive holding cat carriers in each hand.

Around 30 children form semicircles. From each carrier, a pair of bright, sci-fi-like eyes peer into the eager crowd.

“That’s the most fascinating thing ever,” exclaims one child.

Preschoolers have just finished enjoying Deborah Frenkel and Danny Snell’s *Track Cat* for the annual national simultaneous storytime.

Metacut, the two friendly robot pets, are special guests on their inaugural library tour throughout Blue Mountain, New South Wales.


The Blue Mountains City Council states that lifelike cat replicas can offer comfort and alleviate stress, particularly for children and individuals dealing with anxiety and dementia.

Metacuts are capable of meowing and purring. They boast animated LED eyes, soft, hypoallergenic fur, and silicone legs. Yes, the artificial heartbeat resonates within.

With integrated sensors in their head, chin, and back, the cats respond to human interaction, exhibiting realistic movements upon specific voice commands.

When someone says, “I love you, Metacut,” their eyes light up with a glowing heart symbol.

Ewan, captivated by the black cat, bursts into laughter every time it turns its head towards him.

“He’s hooked,” chuckles Ewan’s mother, Amy Cameron, suggesting it’s because it resembles their family cat, Diego.

Meanwhile, 10-year-old Stella becomes enamored with the white cat’s fur, asserting that it evokes “real feelings.” Her six-year-old brother, Charlie, reminisces about Snuffle Pass, their late orange cat.

Dr. Rosemary Dillon, CEO of Blue Mountains City Council, mentions that the council decided to acquire Metacut for the community after discovering them at the 2024 NSW Public Library Association Conference.

Dillon noted that library visitors started interacting with the Metacut, often seeking it out over the human staff.

Metacut has become unexpectedly popular amongst older patrons, Dillon adds. “A significant number of seniors frequent the library for companionship,” she states. “This offers an additional layer of engagement for them.”

Loneliness is a pressing national public health issue, with recent surveys indicating that one in four Australians feels isolated.

Associate Professor Alyssa Milton, a children’s mental health specialist at the University of Sydney, asserts that Metacuts may offer a comforting and reliable connection.

“Robotic pets, or real ones, can help children feel secure and acknowledged,” she explains. “Research indicates that robotic animals show promise in assisting children with various neurological developmental challenges.”

Milton emphasizes that libraries and community spaces play a crucial role in diminishing feelings of social isolation, and Metacut provides an alternative for families who face limitations in owning real pets due to housing circumstances or allergies.


Feedback from Springwood indicates that Metacut has become a favorite.

The children eagerly line up to interact with the animatronic pets.

Stephanie Lambilis, the mother of Stella and Charlie, mentions that the family made a special trip to Springwood just to see the cat. “It’s gentle and sweet,” she comments.

Suggestions for cat names are welcome through the “CAT-FLAP” nomination box at the library until June 7th. Naturally, Stella has submitted her choice, Snuffle Pass.

Professor Adam Guastella, a child neurodevelopment expert at the University of Sydney, mentions that robotic animals can enhance learning and social interaction.

“Early findings indicate that…robotic dogs can foster improved social communication in children with autism,” notes Guastella.

Dr. Nathan Caruana, a cognitive psychology lecturer at Flinders University, concurs that the concept holds promise.

His cutting-edge research on social robots aims to assist children grappling with reading challenges and emotional struggles.

“Children crave attention, and it seems they find motivation with something that doesn’t pass judgment,” he explains.

However, Caruana emphasizes that his research is ongoing, and conclusive evidence supporting the use of robots as mental health tools is still developing.

After completing this tour, the robotic duo will return to what the council describes as their “previous” residences: Springwood and Katoumba Library, while also visiting other libraries for special events.

Deepfakes Are Harder to Spot: Now They Even Have a Heartbeat

Deepfake technology—a method for digitally altering a person’s face or body to impersonate someone else—is advancing at an alarming rate.

This development is discussed in a recent study published in the journal Frontiers of Imaging, which facilitates the creation of some of the most cutting-edge deepfake detectors. These detectors analyze a consistent pattern of blood flow across the face, which has proven to be an unreliable method, complicating the search for harmful content.

Deepfakes are typically generated from “driving videos,” which utilize real footage that artificial intelligence modifies to completely alter a person’s representation in the video.

Not all applications of this technology are harmful; for instance, smartphone apps can age your face or transform you into a cartoon character, showcasing the same underlying techniques for innocent fun.

However, at their most malicious, deepfakes can be used to create non-consensual explicit content, disseminate false information, and unjustly implicate innocent individuals.

In this study, researchers utilized cutting-edge deepfake detectors based on medical imaging methods.

Remote Photoplethysmography (RPPP) measures heartbeats by detecting minute variations in the blood flow beneath the skin, similar to pulse oximeters used in healthcare settings.

The accuracy of the detector is remarkable, with only a 2-3 beats per minute variance when compared to electrocardiogram (ECG) records.

It was previously believed that deepfakes couldn’t accurately replicate these subtle indicators enough to fool RPPP-based detectors, but that assumption has proven incorrect.

“If the driving video features a real person, this information can now be transferred to deepfake videos,” stated Professor Peter Eisert, a co-author of the research, in an interview with BBC Science Focus. “I think that’s the trajectory of all deepfake detectors. As deepfakes evolve, detectors that were once effective may soon become ineffective.”

During testing, the team found that the latest deepfake videos often displayed a remarkably realistic heartbeat, even when deliberately included.

Does this mean we are doomed to never trust online videos again? Not necessarily.

The Eisert team is optimistic that their new detection approach will prove effective. Rather than simply measuring overall pulse rates, future detectors may track detailed blood flow dynamics across the face.

“As the heart beats, blood circulates through the vessels and into the face,” Eisert explained. “This flow is then distributed throughout the facial region, and the movement has a slight time delay that can be detected in genuine footage.”

Ultimately, however, Eisert is skeptical about winning the battle solely with deepfake detection. Instead, he advocates for the use of “digital fingerprints” (encrypted evidence that video content remains untampered) as a more sustainable solution.

“I fear there will come a time when deepfakes are incredibly difficult to detect,” Eisert remarked. “I personally believe that focusing on technologies that verify the authenticity of footage is more vital than just distinguishing between genuine and fake content.”
