Sitting in a gathering room in a startup workplace in Lisbon, I silently typed a query solely the particular person reverse would know the reply to. What sort of espresso had I requested for once I’d arrived on the workplace? A brief second later, with out even shifting or opening his mouth, the reply got here again by way of a textual content message: “You had an Americano.”
This wasn’t how I’d anticipated to spend a Friday afternoon within the metropolis, however right here I used to be, sitting within the workplaces of enterprise language translation companies startup Unbabel, reverse founder and CEO Vasco Pedro, testing what gave the impression to be a brain-to-computer interface. And it was fairly astounding.
The story begins 4 years in the past.
Unbabel’s core mission — permitting enterprises to grasp and be understood by their clients in dozens of languages — way back led the corporate to assume outdoors the proverbial “field,” to develop a number of tasks in-house. It needed to discover different methods to speak. Now, as a startup with $90 million in VC funding, annual revenues of round $50 million and having survived the pandemic, Unbabel is doing nicely sufficient to discover these tasks.
“We had the thought of taking a look at brain-to-communication interfaces,” Pedro tells me. “We began doing a bunch of experiments, like a 20% venture.”
Unbabel’s innovation workforce, led by Paulo Dimas, VP of Product Innovation, regarded into the best way our brains advanced.
“You could have your limbic system, you’ve your neocortex. However they’ve truly advanced over thousands and thousands of years. They’re truly separate methods. And I feel what we’re beginning to see is sort of the creation of the ‘uber cortex,’ which we predict goes to be AI-powered, and it’s going to be present outdoors of your organic mind,” stated Pedro.
Dimas and his workforce began to look into electroencephalogram (EEG) methods, a few of which might be invasive to the physique. Elon Musk’s Neuralink firm is famously exploring invasive brain-computer interface units for people.

EMG was the gateway
However then Unbabel’s workforce hit on the thought of utilizing an EMG system. EMG (electromyography) measures muscle response or electrical exercise in response to a nerve’s stimulation of the muscle. EMG units are commonplace and trivial. You possibly can even purchase them on Amazon for a few bucks.
“What we realized was that EEG was nonetheless too noisy. We needed to be non-invasive. However EMG, which measures muscle response, was so much less noisy. You possibly can extra reliably seize a number of the alerts,” stated Pedro.
The workforce put sensors in an armband and began to work out what they may measure. “We started to think about EMG as a gateway to mind interplay instantly,” Pedro informed me.
Then, final 12 months, they determined to hook up an EMG system with generative AI. Particularly, an LLM, which was personalised to the consumer. However how?
Put merely, the system measured how the wearer of an EMG system would react when pondering of a phrase. This might assist to construct up a set of alerts that correlated to actual phrases. Feeding these alerts into an LLM would imply the creation of a “personalised LLM.”
So once I requested Vasco what sort of espresso I’d requested for by way of an unseen textual content message, he was despatched these phrases by way of an AI voice to his earbuds. He then considered phrases like “Black espresso.” The LLM then matched his bodily response to the phrase, checked if he meant “Americano,” once more by way of the audio in an earbud, after which despatched the reply to me by way of a textual content message — on this use case, the Telegram texting app.
“The LLM expands what you’re saying. After which I affirm earlier than sending it again. So there’s an interplay with the LLM the place I construct what I need it to say, after which I get to approve the ultimate message,” defined Pedro.
The demonstration occurred in entrance of my eyes. There was no shifting or typing. Simply Vasco Pedro silently replying on textual content.
“The LLM that takes a primary immediate and expands it into a completely fledged reply, nearly instantly. I wouldn’t have time to sort all of that within the pure manner. So I’m utilizing the LLM to do the heavy lifting on the response,” he added.
He additionally identified that the wearer has absolute management of what they’re outputting: “It’s not recording what I’m pondering. It’s recording what I need to say. So it’s like having a dialog. Different approaches, like Neuralink, are literally attempting to measure unconscious interactions. We’re making a channel that you should utilize to speak, however the particular person has to need to use it.”
Pedro describes it as like having a voice inside your head you possibly can talk with: “The potential for augmentation is large, however there’s quite a lot of hurdles nonetheless to beat.”
How does it work? The straightforward reply is an “E-Pores and skin” EMG interface embedded in a sort of versatile sleeve, developed with the Printed Microelectronics Laboratory on the University of Coimbra lead by Professor Tavakoli.
Proper now the model is pretty hacked collectively, however ultimately, the system could possibly be miniaturized.
The beginning of Halo
Unbabel dubbed its invention “Halo” (after “halogram”). An app runs on the wearer’s cellphone that allows entry to a central hub for receiving the communication and allows communication with the LLM and responses. The platform is pulling the OpenAI ChatGPT 3.5 proper now.

Pedro likens Unbabel’s venture to driverless automotive firms hacking collectively information from regular cameras reasonably than difficult methods, like lidar: “We’re gonna get a shit-tonne of information, and we are able to begin utilizing it now. We began working 4 years in the past and the tipping level is now when it comes to generative AI. That is the second when that is going to speed up.”
Admittedly, this isn’t the primary time EMG has been used to manage a pc and generate responses.
As an example, a tool made by Fb-owned CTRL-labs had an EMG wristband in 2019 that picked up on electrical impulses that come from muscle fibers as they transfer.
Nevertheless, Unbabel’s method seems as if it might be the primary time an LLM has been hooked as much as EMG on this manner. The functions could possibly be far-reaching.
Unlocking the locked-in
Unbabel is now working with the Champalimaud Foundation in Lisbon, which works on superior biomedical analysis and interdisciplinary medical care within the subject of ALS, amongst many different issues. Clearly, although, the system might find yourself being utilized in different eventualities, resembling Cerebral Palsy.
The necessity for higher interfaces for sufferers who can’t converse is ongoing. Proper now, so-called “Various and Augmentative Communication” (AAC) merchandise for ALS victims, resembling Grid or Tobii, depend on eye-tracking. These methods usually require a irritating calibration course of for the consumer, are actually solely workable indoors and might be fatiguing to the consumer. Additionally they depend upon laboriously gradual keyboards.
As Pedro provides: “Our prototype is already being endorsed by the main ALS affiliation in Portugal. We plan to begin deploying this to our first ALS customers by Xmas this 12 months. Past ALS sufferers, our present product can be related for different sufferers that battle to sort.”
Dimas can be now Unbabel’s appointee to Portugal’s newly shaped Center for Responsible AI, the place he’s CEO. This can be a partnership with a number of Portuguese startups and analysis facilities to speculate €78 million in AI analysis, creating 210 jobs below the Portuguese Recovery and Resilience Plan. Companions embrace Feedzai, Sword Well being, Champalimaud Basis and others.
Generative AI is coming to wearable units
In the meantime, the model of Halo demonstrated to me confirmed the potential energy for generative AI utilized to wearable units. Different groups are exploring this courageous new world. Simply this week neuroscientists have been in a position to recreate Pink Floyd’s “One other Brick within the Wall, Half 1” utilizing AI to decipher the mind’s electrical exercise.
The idea has been round for a very long time. Within the Eighties, the Firefox movie, directed by and starring Clint Eastwood, posited a world the place pilots would management weapons methods by way of thought-controlled platforms:
However that is solely the primary model of Unbabel’s Halo: “It’s nonetheless pretty restricted to what we are able to do, however we’re already at round 20 phrases per minute of equal communication,” stated Pedro.
“To offer you a way of this, Stephen Hawking was speaking at round two phrases per minute. Halo is now at round 20 phrases per minute. Client-use degree is 60, and 80 is the goal. Individuals discuss at a most of 120 to 130 phrases per minute. So in case you get to 150, you’re beginning to get to superhuman capabilities.”
