Think about a single know-how that might assist a robotic carry out security checks at a nuclear plant, treatment an individual’s arachnophobia and simulate the sensation of a hug from a distant relative.
Welcome to the world of “prolonged actuality”. Researchers funded by the EU have sought to exhibit its huge potential.

Their objective was to make augmented actuality, wherein the true world is digitally enhanced, and digital actuality – a totally computer-generated setting – extra immersive for customers.
One of many researchers, Erik Hernandez Jimenez, by no means imagined the instant relevance of a undertaking that he led when it began in mid-2019. Inside a 12 months, the Covid-19 pandemic had triggered numerous lockdowns that left folks working and socialising by way of video connections from dwelling.
‘We thought of the best way to apply this know-how, the best way to really feel human contact even at a distance, after we had been all locked at dwelling and phone with others was by way of a pc,’ mentioned Hernandez Jimenez.
He coordinated the EU analysis initiative, which was named TACTILITY and ran from July 2019 till the top of September 2022.
The TACTILITY crew developed a glove that simulates the sense of contact. Customers have the feeling of touching digital objects by way of electrical pulses delivered by electrodes embedded within the glove.
The sensations vary from pushing a button and feeling strain on the finger to dealing with a stable object and feeling its form, dimensions and texture.
Glove and swimsuit
‘TACTILITY is about together with tactile suggestions in a virtual-reality situation,’ mentioned Hernandez Jimenez, who’s a undertaking supervisor at Spanish analysis institute TECNALIA.
He mentioned the precept might be prolonged from the glove to an entire physique swimsuit.
In contrast with previous makes an attempt to simulate contact sensations with motors, the electro-tactile suggestions approach produces a extra lifelike consequence at a decrease price, in line with Hernandez Jimenez.
This opens up the opportunity of making the know-how extra extensively accessible.
The analysis bolsters European Fee efforts to develop the virtual-worlds area, which might present 860 000 new jobs in Europe this decade because the worldwide sector grows from €27 billion in 2022.
The EU has round 3 700 corporations, analysis organisations and governmental our bodies that function on this sphere, in line with the Fee.
Phobias to factories
The TACTILITY researchers checked out potential healthcare functions.

That’s the place spiders come into the image. They had been among the many objects within the undertaking’s experiments to imitate contact.
‘One which was fairly spectacular – though I didn’t prefer it in any respect – was feeling a spider or a cockroach crawling over your hand,’ Hernandez Jimenez mentioned.
A possible use for the know-how is treating phobias by way of publicity remedy wherein sufferers are steadily desensitised to the supply of their concern. That would begin by nearly “touching” cartoon-like creepy crawlies earlier than progressing to extra lifelike variations.
The tactile glove will also be used within the manufacturing business, serving to the likes of automobile producers prepare their staff to carry out tough manoeuvres on the manufacturing facility flooring.
Moreover, it may possibly assist folks collaborate extra successfully with remotely managed robots in hazardous environments. An instance is a nuclear energy plant, the place an individual in a management room can nearly “really feel” what a robotic is touching.
‘They get one other sense and one other type of suggestions, with extra info to carry out higher checks,’ Hernandez Jimenez mentioned.
Joyful and playful

Wearable applied sciences for virtual-reality environments are additionally being impressed by the gaming business.
Researchers in a second EU-funded undertaking sought to increase the prospects for applied sciences already extensively used for skilled functions. The initiative, known as WEARTUAL, ran from Might 2019 till late 2021.
“Wearables are trend gadgets – they’re a part of the best way we assemble our id.”

‘Our undertaking targeted on the extra experiential aspect – joyful and playful actions,’ mentioned Oğuz ‘Oz’ Buruk, who coordinated WEARTUAL and is assistant professor of gameful expertise at Tampere College in Finland.
Till lately, experiencing a virtual-reality setting concerned a hand-held controller or head-mounted show.
The WEARTUAL researchers checked out methods of incorporating wearables worn, for instance, on the wrist or ankle into digital actuality to offer folks a way of larger immersion.
That would imply having their avatar – a consultant icon or determine within the digital world – blush when nervous or excited to reinforce their skill to specific themselves.
On the cusp
The crew developed a prototype that might combine various bodily sensations into the digital world by transferring to it real-life information resembling coronary heart fee.
Buruk is inquisitive about how video games will look within the “posthuman” period, when folks and machines more and more converge by way of bodily implants, robotics and direct communication between the human mind and computer systems.
He alerts that it’s onerous to overestimate the eventual affect of advances on this space on on a regular basis life, albeit over various timescales: wearables are more likely to be rather more extensively utilized in digital actuality within the subsequent decade, whereas widespread use of bodily implants is extra more likely to take 50 to 100 years.
As know-how and human our bodies grow to be ever extra intently linked, the expertise of transferring them to a digital world will probably be enhanced, encouraging folks to spend growing quantities of time there, in line with Buruk.
Digital-reality applied sciences are already getting used for sensible functions resembling gamifying very important info together with fire-safety procedures, making it extra interactive and simpler to be taught. This kind of use might increase to many areas.
On a really totally different entrance, a number of trend homes already promote garments that may be worn in digital environments, permitting folks to specific their id and creativity.
‘Wearables are trend gadgets – they’re a part of the best way we assemble our id,’ Buruk mentioned. ‘Investments in digital actuality, prolonged actuality and augmented actuality are growing day by day.’
