Think about a single know-how that would 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 display its huge potential.

Their objective was to make augmented actuality, during which the actual world is digitally enhanced, and digital actuality – a totally computer-generated atmosphere – extra immersive for customers.
One of many researchers, Erik Hernandez Jimenez, by no means imagined the fast relevance of a venture that he led when it began in mid-2019. Inside a yr, the Covid-19 pandemic had triggered numerous lockdowns that left folks working and socialising by means of video connections from house.
‘We thought of methods to apply this know-how, methods to really feel human contact even at a distance, after we had been all locked at house and call with others was by means of a pc,’ mentioned Hernandez Jimenez.
He coordinated the EU analysis initiative, which was named TACTILITY and ran from July 2019 till the tip of September 2022.
The TACTILITY group developed a glove that simulates the sense of contact. Customers have the feeling of touching digital objects by means 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 venture supervisor at Spanish analysis institute TECNALIA.
He mentioned the precept may very well 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 real looking end result at a decrease value, in keeping 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 keeping 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 venture’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 means of publicity remedy during which sufferers are step by step desensitised to the supply of their concern. That might begin by just about “touching” cartoon-like creepy crawlies earlier than progressing to extra lifelike variations.
The tactile glove can be used within the manufacturing trade, serving to the likes of automotive producers practice their employees to carry out tough manoeuvres on the manufacturing facility ground.
Moreover, it may well 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 just about “really feel” what a robotic is touching.
‘They get one other sense and one other sort 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 trade.
Researchers in a second EU-funded venture sought to develop 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 vogue gadgets – they’re a part of the way in which we assemble our identification.”
– Oğuz ‘Oz’ Buruk, WEARTUAL
‘Our venture centered on the extra experiential facet – 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 atmosphere 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 provide folks a way of better immersion.
That might imply having their avatar – a consultant icon or determine within the digital world – blush when nervous or excited to reinforce their capacity to specific themselves.
On the cusp
The group developed a prototype that would combine various bodily sensations into the digital world by transferring to it real-life information akin to coronary heart price.
Buruk is taken with how video games will look within the “posthuman” period, when folks and machines more and more converge by means of bodily implants, robotics and direct communication between the human mind and computer systems.
He indicators that it’s laborious to overestimate the eventual influence of advances on this space on on a regular basis life, albeit over various timescales: wearables are prone to be far more extensively utilized in digital actuality within the subsequent decade, whereas widespread use of bodily implants is extra prone to take 50 to 100 years.
As know-how and human our bodies develop into ever extra carefully linked, the expertise of transferring them to a digital world will probably be enhanced, encouraging folks to spend rising quantities of time there, in keeping with Buruk.
Digital-reality applied sciences are already getting used for sensible functions akin to gamifying important info together with fire-safety procedures, making it extra interactive and simpler to be taught. The sort of use might develop to many areas.
On a really completely different entrance, a number of vogue homes already promote garments that may be worn in digital environments, permitting folks to specific their identification and creativity.
‘Wearables are vogue gadgets – they’re a part of the way in which we assemble our identification,’ Buruk mentioned. ‘Investments in digital actuality, prolonged actuality and augmented actuality are rising day-after-day.’
