Jeremy is a 31-year-old autistic man who loves music and biking. He’s extremely delicate to lights, sounds, and textures, has issue initiating motion, and may say only some phrases. All through his education, it was assumed he was incapable of studying to learn and write. However for the previous half-hour, he’s been sporting an augmented-reality (AR) headset and spelling single phrases on the HoloBoard, a digital keyboard that hovers within the air in entrance of him. And now, on the finish of a examine session, a researcher asks Jeremy (not his actual title) what he considered the expertise.
Intentionally, poking one digital letter at a time, he varieties, “That was good.”
It was not apparent that Jeremy would have the ability to put on an AR headset, not to mention use it to speak. The headset we use,
Microsoft’s HoloLens 2, weighs 566 grams (greater than a pound), and the straps that encircle the pinnacle may be uncomfortable. Interacting with digital objects requires exact hand and finger actions. What’s extra, some individuals doubt that individuals like Jeremy may even perceive a query or produce a response. And but, in examine after examine, we have now discovered that the majority nonspeaking autistic teenage and grownup contributors can put on the HoloLens 2, and most can sort quick phrases on the HoloBoard.
Nonspeaking autistic individuals can use the HoloBoard to sort independently.
The HoloBoard prototype that Jeremy first utilized in 2023 was three years within the making. It had its origins in an interdisciplinary
feasibility study that thought-about whether or not people like Jeremy might tolerate a business AR headset. That examine was led by the three of us: a developmental psychologist (Vikram Jaswal on the College of Virginia), {an electrical} and software program engineer (Diwakar Krishnamurthy on the College of Calgary), and a pc scientist (Mea Wang, additionally on the College of Calgary).
Our journey so far was not easy. Some autism researchers advised us that nonspeaking autistic individuals “would not have language” and so couldn’t presumably talk by typing. In addition they stated that nonspeaking autistic individuals are so delicate to sensory experiences that they’d be overwhelmed by augmented reality. However our information, from greater than a half-dozen peer-reviewed research, have proven each assumptions to be fallacious. And people outcomes have knowledgeable the instruments we’re creating, just like the HoloBoard, to allow nonspeaking autistic individuals to speak extra successfully.
What Is Nonspeaking Autism?
Autism is a lifelong neurological situation that impacts individuals in very other ways. It’s mostly related to social variations, however many autistic individuals even have issue with communication. The truth is, about
one-third of autistic youngsters and adults are nonspeaking: Even after years or many years of speech remedy, they can’t talk successfully utilizing speech. We don’t but know why, however it could be associated to the significant motor challenges related to producing speech. As with autism basically, nonspeaking autistic individuals have a variety of skills and language abilities: Some are snug typing, whereas others battle to speak in any respect.
Nonspeaking autistic individuals may additionally seem inattentive, interact in impulsive habits, and rating poorly on normal intelligence checks (lots of which require spoken responses inside a set period of time). Traditionally, these challenges have led to unfounded assumptions about these people’ potential to grasp language and their capability for symbolic thought. To place it bluntly, it has typically been assumed that somebody who can’t discuss
is also incapable of thinking.
Most makes an attempt to offer nonspeaking autistic individuals with an alternative choice to speech have been rudimentary.
Picture-based communication systems, typically carried out on an iPad or pill, are steadily utilized in faculties and remedy clinics. If a person desires a cookie, they will faucet an image of a cookie. However the vocabulary of those programs is proscribed to the ideas that may be represented by a easy image.

There are different choices. Some nonspeaking autistic individuals have realized, over the course of a few years and guided by dad and mom and professionals, to speak by spelling phrases and sentences on a letterboard that’s held by a educated human assistant—a communication and regulation companion, or CRP. A part of the CRP’s function is to offer attentional and emotional assist, which might help with situations that generally accompany extreme autism and that intervene with communication, together with anxiousness, attention-deficit hyperactivity dysfunction, and obsessive-compulsive dysfunction. Accessing such assisted strategies of communication has allowed nonspeaking autistic individuals to
graduate from college, write poetry, and publish a best-selling memoir.
However the function of the CRP has generated appreciable controversy.
Critics contend that the assistants can subtly information customers to level to explicit letters, which might make the CRP, moderately than the person, the writer of any phrases produced. If nonspeaking autistic individuals who use a letterboard actually know tips on how to spell, critics ask, why is the CRP vital? Some skilled organizations, together with the American Speech-Language-Hearing Association, have even cautioned in opposition to educating nonspeaking autistic individuals communication strategies that contain help from one other individual.
And but, analysis means that CRP-aided strategies can educate customers the abilities to speak
with out help; certainly, some people who beforehand required assist now sort independently. And a current examine by coauthor Jaswal confirmed that, opposite to critics’ assumptions, a lot of the nonspeaking autistic people in his examine (which didn’t contain a CRP) knew how to spell. For instance, in a string of textual content with none areas, they knew the place one phrase ended and the following phrase started. Utilizing eye tracking, Jaswal’s workforce additionally confirmed that nonspeaking autistic individuals who use a letterboard have a look at and level to letters too quickly and accurately to be responding to refined cues from a human assistant.
Our AR Method to Autism
So how can know-how assist nonspeaking autistic individuals talk? It’s common for researchers to take a look at a platform know-how like AR and picture the way it could possibly be used to assist a bunch of individuals. Nonetheless, the final word success of any such challenge isn’t judged by technical innovation or class. Fairly, the principle criterion for achievement is whether or not or not the tip result’s used and helpful. A tremendous know-how that’s, say, too delicate or costly to flee the laboratory is of restricted worth. And a raft of improvements that miss the mark in assembly the wants of the individuals it’s supposed to assist is equally restricted.
Our focus then was not on bettering underlying AR {hardware} and system software program, however discovering the best methods to adapt it for our customers.
We knew we needed to design a typing system that may permit customers to convey something they needed. And given the continued controversy about assisted communication, we needed a system that might construct the abilities wanted to sort independently. We envisioned a system that may give customers extra company and probably extra privateness if the software is used outdoors a analysis setting.

Augmented actuality has varied options that,
we reasoned, make it enticing for these functions. AR’s eye- and hand-tracking capabilities could possibly be leveraged in actions that prepare customers within the motor abilities wanted to sort, reminiscent of isolating and tapping targets. A few of the CRP’s duties, like providing encouragement to a person, could possibly be automated and rolled into an AR system. Additionally, AR permits customers to maneuver round freely as they interact with digital objects, which can be extra appropriate for autistic individuals who have bother staying nonetheless: A HoloBoard can “observe” the person round a room utilizing head monitoring. What’s extra, digital objects in AR are overlaid on a person’s precise setting, making it safer and fewer immersive than virtual reality (VR)—and probably much less overwhelming for our goal inhabitants.
We rigorously thought-about our selection of {hardware}. Whereas light-weight AR glasses just like the Ray-Ban Meta AI glasses and
Snap’s AI Spectacles would have been much less cumbersome for customers, they don’t have the high-fidelity hand-tracking and gaze-tracking we wanted. Headsets just like the HoloLens 2 and Meta’s Quest 3 present higher computing energy and assist a broader vary of interplay modalities.
We aren’t the primary researchers to think about how AR might help autistic individuals. Different teams have used AR to supply autistic youngsters real-time details about the
emotions individuals present on their faces, for instance, and to gamify social- and motor-skill training. We drew inspiration from these efforts as we took on the brand new thought of utilizing AR to assist nonspeaking autistic individuals talk.
A Collaborative Design Venture
Our efforts have been powered by our shut collaboration with nonspeaking autistic individuals. They’re, in any case, the specialists about their situation, and so they’re the individuals greatest suited to information the design of any instruments supposed for them. Every little thing we do is knowledgeable by their enter, together with the design of prototypes and the research to check these prototypes.
When neurotypical individuals see somebody who can’t discuss, whose physique strikes in uncommon methods, and who acts in socially unconventional methods, they could assume that the individual wouldn’t be all for collaborating or wouldn’t give you the chance to take action. However, as famous by
Anne M. Donnellan and others who conduct analysis with disabled individuals, behavioral variations don’t essentially mirror underlying capacities or a lack of interest in social engagement. These researchers have emphasised the significance of presuming competence—in our case, meaning anticipating nonspeaking autistic individuals to have the ability to study, suppose, and take part.
Thus, all through our challenge, we have now invited nonspeaking autistic individuals to supply options and suggestions in no matter method they like, together with by pointing to letters on a bodily letterboard whereas supported by a CRP. Though critics of assisted types of communication might object to this inclusive strategy, we have now discovered the contributions of nonspeakers invaluable. By way of Zoom conferences, e mail correspondence, feedback after analysis classes, and shared Google docs, these contributors have supplied important enter about whether or not and the way the AR know-how we’re growing could possibly be a helpful communication software. Consistent with the group’s curiosity in additional impartial communication, our checks of the know-how have centered on nonspeakers’ efficiency
with out the help of a CRP.

In early conversations, our collaborators raised a number of issues about utilizing AR. For instance, they anxious that sporting a head-mounted system wouldn’t be snug. Our
first study investigated this matter and located that, with applicable assist and enough time, 15 of 17 nonspeakers wore the system with out issue. We now have 3D-printed fashions that replicate the form and weight of the HoloLens 2, to permit contributors to construct up tolerance earlier than they take part in precise experiments.
Some customers additionally expressed concern concerning the potential for sensory overload, and their issues made us notice that we hadn’t adequately defined the distinction between AR and VR. We now present a
video earlier than every examine that explains precisely what contributors will do and see and exhibits how AR is much less immersive than VR.
Some contributors advised us that they just like the tactile enter from interacting with bodily objects, together with bodily letterboards, and have been involved that digital objects wouldn’t replicate that have. We at the moment tackle this concern utilizing
sensory substitution: Letters on the HoloBoard hover barely in entrance of a semitransparent digital backplate. Activating a letter requires the person to “push” it roughly 3 centimeters towards the backplate, and profitable activation is accompanied by an audible click on and a recorded voice saying the letter aloud.
Nonspeakers’ Preferences and Targets
Our customers’ wants and preferences have helped us set priorities for our analysis program. One individual famous that an AR communication system appeared “cool,” however anxious that the motor abilities required to work together in AR may not be attainable with out follow. So from the
very first app we developed, we inbuilt actions to let customers follow the motor abilities they wanted to succeed.
Individuals additionally advised us they needed to have the ability to customise the holograms—not simply to go well with their aesthetic preferences but additionally to higher match their distinctive sensory, motor, and attentional profiles. In consequence, customers of the HoloBoard can select its colour scheme and the scale of the digital letterboard, and whether or not the letters are stated aloud as they’re pressed. We’ve additionally supplied a number of methods to
activate letters: by urgent them, them, or them whereas utilizing a bodily clicker.
We had initially assumed that customers could be all for predictive textual content capabilities for the HoloBoard—having it autofill probably phrases based mostly on the primary letters typed. Nonetheless, a number of individuals defined that though such a system might theoretically velocity up communication, they’d discover it distracting. We’ve put this concept on the again burner for now; it could ultimately change into an choice that customers can toggle on if they want.
To make issues simpler for customers, we’ve investigated whether or not the HoloBoard could possibly be positioned robotically in house, dynamically adjusting to the person’s motor abilities and motion patterns all through a session. To this finish, we used a
behavioral cloning strategy: Throughout real-world interactions between nonspeakers and their CRPs, we noticed the place of the person’s fingers, palms, head, and bodily letterboard. We then used that information to coach a machine learning mannequin to robotically adapt the position of a digital letterboard for a selected person.
So many assumptions are made about individuals who can’t communicate, together with that they don’t have something to say.
Many nonspeaking contributors who at the moment talk with human help see the HoloBoard as offering a solution to talk with extra autonomy. Certainly, we’ve discovered that after a 10-minute coaching process, most customers of the HoloBoard can, like Jeremy,
use it to type short words independently. We lately started a six-month examine with 5 contributors who’ve common classes in constructing their typing abilities on the HoloBoard.
Some of the widespread questions from our nonspeaking contributors, in addition to from dad and mom and professionals, is whether or not AR might educate the abilities wanted to sort on a typical keyboard. It appears attainable, in principle. As a primary step, we’re creating different varieties of AR educating instruments, together with an
educational AR app that teaches typing within the context of participating and age-appropriate classes.
We’ve additionally begun growing a
virtual CRP that may supply assist and suggestions as a person interacts with the digital letterboard. This digital assistant, named ViC, can show motor actions as a person is studying to spell with the HoloBoard, and likewise presents verbal prompts and encouragement throughout a coaching session. There aren’t many professionals who know tips on how to educate nonspeakers typing abilities, so a digital CRP could possibly be a recreation changer for this inhabitants.
Sensible and Technical Challenges of AR
Though nonspeakers have responded enthusiastically to our AR communication instruments, our conversations and research have revealed plenty of sensible challenges with the present know-how.
For starters, most individuals can’t afford Microsoft’s HoloLens 2, which
costs US $3,500. (It’s additionally lately been discontinued!) So we’ve begun testing our software program on cheaper mixed-reality merchandise reminiscent of Meta’s $500 Quest 3, and preliminary outcomes have been promising. However no matter which system is used, most headsets are cumbersome and heavy. It’s unlikely that somebody would put on one all through a college day, for instance. One thought we’re pursuing is to design a pair of AR glasses that’s only for digital typing; a tool personalized for a single operate would weigh a lot lower than a general-purpose headset.

We’ve additionally encountered technical challenges. For instance, the HoloLens 2’s discipline of view is just 52 levels. This restricts the scale and placement of holograms, as bigger holograms or these positioned incorrectly could also be partially or solely invisible to the person. So when contributors use their fingers to level at digital letters on the HoloBoard, some letters close to the perimeters of the board might fall outdoors the seen space, which is irritating to customers. To handle these points, we used a vertical format in our
educational app in order that the multiple-choice buttons all the time stay inside a person’s discipline of view. Our programs additionally permit a researcher or caregiver to watch an AR session and, if vital, alter the scale of digital objects in order that they’re all the time in view.
We’ve a number of different concepts for coping with the field-of-view challenge, together with deploying gadgets which have a bigger discipline of view. One other technique is to make use of eye monitoring to pick letters, which might eradicate the reliance available actions and the issue of the person’s pointing fingers obscuring the letters. And a few customers would possibly favor utilizing a joystick or different handheld controller to navigate and choose letters. Collectively, these methods ought to make the system extra accessible whereas working inside {hardware} constraints.
We’ve additionally been growing
cross-reality apps, which permit two or extra individuals sporting AR headsets to work together inside the similar digital house. That’s the setup we use to allow researchers to watch examine classes in actual time. Based mostly on our improvement expertise, we created an open-source software referred to as SimpleShare for the event of multiuser extended-reality apps in a device-agnostic means. A associated challenge is that lots of our customers make sudden actions; a sudden shake of a head can intervene with the sensors on the AR headset and upset the spatial alignment between a number of headsets. So our apps and SimpleShare instruct the headset to routinely scan the setting and use that information to robotically realign a number of gadgets, if vital.
We’ve needed to discover options to deal with the restricted computing energy accessible on AR headsets. Operating the AI mannequin that automates the
custom placement of the HoloBoard for every person could cause a lag in letterboard interactions and may trigger the headset to warmth up. We solved this downside by simplifying the AI mannequin and reducing the frequency of the mannequin’s interventions. Rendering a sensible digital CRP through a headset can be computationally intensive. In our virtual CRP work, we’re now rendering the avatar on an edge system, reminiscent of a laptop computer with a state-of-the-art GPU, and streaming it to the show.
As we proceed to sort out these know-how challenges, we’re nicely conscious that we don’t have all of the solutions. That’s why we focus on the issues that we’re engaged on with the nonspeaking autistic individuals who will use the know-how. Their views are serving to us make progress towards a very usable and helpful system.
Everybody Deserves to Be Heard
So many assumptions are made about individuals who can’t communicate, together with that they don’t have something to say. We went into this challenge presuming competence in nonspeaking individuals, and but we nonetheless weren’t positive if our contributors would have the ability to adapt to our know-how. In our
initial work, we have been not sure whether or not nonspeakers might put on the AR system or work together with digital buttons. They simply did each. In our evaluation of the HoloBoard prototype, we didn’t know if customers might sort on a digital letterboard hovering in entrance of them. They did so whereas we watched. In a current study investigating whether or not nonspeakers might choose letters utilizing eye-gaze monitoring, we questioned if they may full the built-in gaze-calibration process. They did.
The power to speak—to share info, recollections, opinions—is crucial to well-being. Sadly, most autistic individuals who can’t talk utilizing speech are
never provided an effective alternative. And not using a solution to convey their ideas, they’re disadvantaged of academic, social, group, and employment alternatives.
We aren’t so naïve as to suppose that AR is a silver bullet. However we’re hopeful that there shall be extra group collaborations like ours, which take severely the lived experiences of nonspeaking autistic individuals and result in new applied sciences to assist them. Their voices could also be caught inside, however they need to be heard.
