In this altered excerpt from " The time to come of Language : How Technology , Politics and Utopianism are Transforming the Way We Communicate " ( Bloomsbury , 2023 ) , author Philip Seargeant examines brain computer interfaces design to serve locked - in patients communicate , and why applied science companies like Facebook are using them as the basis for wearable machine that could transform , for good or ill , how everyday user communicate .
When my grandmother suffer a solidus some years ago , for several days she completely lost the ability to communicate . The whole left side of her organic structure , from her scalp to the sole of her groundwork , was paralysed , and for those first few days she could barely move . She could n’t mouth at all ; the best she could manage , if she need to draw our attention to something , was to gesture vaguely with her one adept hand . Once the aesculapian team had settled her in the ward , she keep purloin her finger’s breadth to her lips with an more and more exasperated look in her eyes . It aim me an years to realize that she was indicating she wanted something to drink . She ’d been lie helpless on the trading floor of her theatre for almost twenty - four hours before she was discovered , and by now she was urgently thirsty .

When the hospital ’s speech therapist came around to visit a day or two afterwards she pass on us a ‘ communicating circuit board ’ . This was fundamentally just a piece of composition board , more or less tattered at the edges , with the letters of the alphabet printed on one side . On the other side there were a few simple pictures – epitome of a bottle of pills , a cluster of kin members , a vicar , that sort of thing . If my grandmother wanted to enjoin us something , now she pointed easy from letter to letter , spell out central words . It was a tortuously boring outgrowth , specially with her coordination science still so rickety . It also required a lot of guess on the part of the person she was lecture to , as they had to attempt to set up together , from isolated words , the full meaning of what she was taste to transmit .
Finding ways to make the brainiac speak is at the spirit of inquiry into what is known as brain - information processing system interface ( or BCI ) technology , an area of neuroscience that ’s investigating how we can control machine with our minds . BCI technology works by the use of sensors , target either in or around the brain , which pick up neural action that can then be read by a computer and used to lock outside devices . It ’s a mean of establishing a communication path between reckoner and brain which does n’t rely on the muscular movement that has hitherto allowed for the port between the two . It ’s a form of existent - lifespan nous controller , allowing people to execute round-eyed tasks using nothing more than the power of thought . And one of the tasks that ’s presently being work on by researchers is the idea of ‘ type ’ with the brain .
field of study show that this variety of BCI applied science can provide a way for patients with locked - in syndrome to communicate via a BCI good speller , or for paraplegic to control prosthetic branch or computerized equipment . It ’s other days for this variety of research , but already there are encouraging signs of what might be possible . In 2017 , a small radical of participant on a task in the United States , all of whom were paralysed ( one had suffered a spinal injury ; the others had Lou Gehrig ’s disease ) , were able to ‘ type ’ with their brains at somewhere between three and eight words per bit . Okay , so this is n’t peculiarly fast . A professional typist average up to eighty words per minute , and smartphone users can make do about thirty - eight words per minute . But it already equal a patient struggling to get by with a ‘ communicating board ’ . And it ’s boundlessly better than having no access code to communication at all .

The participant in this special discipline had bantam electrode implant on the aerofoil of their brains , penetrating about a mm into the motor cortex . These were get in touch to a serial of wires protruding from their head which were then attached to a web of cable . For casual , everyday utilize this is clearly a bit unwieldy . But , as I say , it ’s early days for the research and the intent is to achieve interchangeable result through the use of wireless implants or ‘ non - invasive ’ devices such as headsets place over the scalp ( although the closer one can get to the sign that needs to be read , the decipherable that sign is ) .

The potential , and the market , is n’t limited merely to helping those with speech impairments . Unsurprisingly , both the entertainment industry and the military see great possibilities in the technology . Then there are the expectant tech companies who are currently plow huge amount of money into this research . They see it as a universal technology which will revolutionize the way we relate both with each other and , maybe more significantly ( at least from their spot of scene ) , with our digital devices . In 2019 Facebook Labs introduced their vision for a future enhanced by BCI technologies by ask in us to ‘ imagine a human race where all the knowledge , fun , and public-service corporation of today ’s smartphones were instantly accessible and completely hands - free ’ . This notional world is one in which the multiple capabilities of the smartphone are n’t limited to a small black box you manipulate with your hand . Instead , the architectural plan is for a non - trespassing system that you’re able to wear on your head . For Mark Zuckerberg , chief operating officer of Facebook , non - invasive solutions are preferred not only because they sidestep the difficulty that are induce by the body rejecting physical implant ( which is proving to be a real trouble for many projects ) but also because , as he somewhat sardonically noted to his colleague , he ’d wish to avoid having to give testimony at a congressional hearing on allegations that Facebook now require to do brainiac operating room on its user .
The Facebook architectural plan is for a wearable BCI equipment which , they say , will be ‘ realized in the ultimate form factor of a pair of stylish , augment reality chalk ’ . Among the many things this will allow you to do is to ‘ type ’ at 100 words per minute . Should this be achievable , not only would it surpass current judgement - typecast top speed of eight lyric per second but it would also better what all smartphone users and most professional typists can manage .
It ’s an challenging vision for wearable technical school . Facebook ’s current chic glass – their collaboration with Ray Ban for the ‘ Ray Ban Stories ’ – are a rather more earthbound appendage to the smartphone . They can take photos and video , play music and run as a telephone set receiver . Other company develop smart glass have more augmented reality feature film embedded in their products . But at the here and now , probably the most striking impact of what ’s available now is n’t break to be what you may do so much as how and where you may do it , and what this means for our ideas of privateness . Facebook provides a checklist of honorable pointer that customers might want to take into consideration – turn the glass off in the locker way or public lavatory ; ‘ be mindful of taking photos around minors ’ – but this seems just to highlight potential problems rather than work out them .
There are similar concerns about the direction in which BCI ontogenesis might take . Concerns about what a Earth in which everyone ’s brain activity is cop up to the internet would look like , and the import it would have not only for privacy but also for security and mental wellbeing . Facebook may be trying to sound a relentlessly positive short letter in its press going , but for lots of people today the smartphone is no longer simply a symbol of ‘ noesis , fun and utility ’ . It ’s also a source of dependence , distraction and overworking . So the idea of having its equivalent plugged straight into your brainiac ( or even just resting on the bridgework of your olfactory organ as a twain of stylish , augment world glasses ) is n’t without its worries . The dystopian possibilities seem dateless . To give just a single model , one of the many affair that BCI technology is able to do is monitor your levels of engrossment . As one technical school writer has suggested , it ’s not hard to suppose a creation where companionship resolve to exploit this by creating systems which track their employees ’ brain data as part of their performance rating . In a macrocosm in which companies are already monitoring everything from their employees ’ computer utilisation to their bathroom breaks , it would only be a small step to include neural read - outs of their attention levels as well . You ’d never again be able to casually rest your head on your hands as if in deep thought while surreptitiously take a short snooze , as the BCI data would be there to betray you .
But there are also doubtfulness of what this sort of engineering science will think for how we actually commune , and for what the time to come of nomenclature will look like . As we ’ve control , Modern communication technology never just replace old ones without also bringing about various changes – changes in the way we relate to one another , in the feeling of the nomenclature we use and in the shape of the society in which we live .
