Low-Tech AAC: PECS, Core Boards, and Pointing

Last April, a mom named Dana in Tucson laminated a core word board at a FedEx for $3.80. Her four-year-old son Marcus, minimally verbal and on a nine-month waitlist for a speech-generating device through insurance, started pointing to "want" and "more" within a week. Dana told his SLP: "I spent months thinking he couldn't communicate until we had a device. Then a sheet of paper proved me wrong."

That story is not unusual. Low-tech AAC (paper picture systems, core boards, communication books, eye gaze with a partner, pointing) is sometimes treated as the consolation prize, the thing you use while waiting for the real system. That framing is wrong. Low-tech AAC is real AAC. It is often the entry point, frequently the backup, and for some communicators, the preferred long-term system.

The strength is reliability. It never crashes. The limit is vocabulary scope.

This article covers the main low-tech options, what each one actually does well, and where each one falls short. AAC decisions are best made with an SLP trained in AAC, not from a blog post. But understanding the landscape helps you ask better questions in that meeting.

LittleWords is a speech-practice companion, not an AAC system. This article is about real AAC options for non-speaking or minimally verbal communicators.

The Low-Tech Category, Quickly

Low-tech AAC means non-electronic communication supports. The lineup:

High-tech AAC means electronic devices and apps with speech output. Both belong in the toolkit. They are not competing philosophies.

Where Low-Tech Fits Best (and Where It Doesn't)

Here's the thing about low-tech: its best use cases are specific and practical, not theoretical.

It goes where electronics can't. The pool. The bath. A muddy soccer sideline. Sand. Rain. A laminated board survives all of it.

It works when the device is dead. Every AAC user with a device should have a low-tech backup. Batteries die at the worst possible moment. Communication access shouldn't depend on a charging cable.

It serves narrow, high-frequency routines beautifully. A choice board on the fridge for snack time is faster than opening an app and navigating folders. Three pictures. Goldfish, crackers, apple. Done.

It bridges the funding gap. Insurance authorization and school district funding for speech-generating devices can take months. Low-tech gives communication access at near-zero cost right now, while the paperwork grinds forward.

Some communicators prefer it. Full stop. Preference is a valid reason.

Where low-tech runs out of room: a child who needs to say complex things, build full sentences, and communicate with people who aren't trained partners. A binder holds only so many pages. A picture card requires someone present to receive it. For daily, independent, rich communication, most AAC specialists now recommend high-tech as the primary system, with low-tech as the backbone backup.

PECS: The Most Famous, Most Misunderstood

PECS (Picture Exchange Communication System), developed by Andy Bondy and Lori Frost in 1985, is the low-tech system people have heard of. It has six phases, moving from basic picture exchange (child hands a card to a partner) to more complex sentence strips. Decades of research back its effectiveness, especially for autistic children.

What PECS does well: it teaches the function of communication. The physical exchange (I give you this card, you give me the thing) is concrete. A child learns that communication is a transaction, that expressing something produces a result.

Where PECS falls apart for some families: you need the protocol training to implement it correctly. The vocabulary is limited by how many cards you can carry. And the exchange model requires a partner to be physically present and paying attention. That's a real constraint.

My honest take: PECS is a strong introduction tool and a good fit for some stages, but treating it as a destination rather than a launchpad does many communicators a disservice. Modern AAC research generally points toward more solid systems (often high-tech) as the long-term primary tool. PECS is one instrument, not the whole orchestra.

Core Boards and Why They Punch Above Their Weight

A core board is a single laminated page (or card) with the thirty to fifty most frequently used words in any language: I, you, want, more, go, stop, help, like, look, get, all done.

The math behind core boards is compelling. A relatively small set of high-frequency words accounts for a huge percentage of everyday communication. A child with reliable access to "more," "want," "stop," "help," "go," and "all done" can express a surprising range of meaning.

Free printable core boards are available from Saltillo, AssistiveWare, and other AAC manufacturers. Your SLP can recommend or print one matched to your child's level.

How to actually use one:

Here's the practical bonus: most high-tech AAC systems organize their home screens around core words too. So a child who learns core vocabulary on a paper board carries that skill directly into a device. The transition is not starting over. It's graduating to a bigger stage.

Communication Books and PODD

A communication book is a binder with multiple pages of vocabulary organized by topic or category. The user (or partner) flips to the right page, then points to the word.

The most well-known system in this category is PODD (Pragmatic Organization Dynamic Display), designed by Gayle Porter. PODD organizes vocabulary in a way that supports natural conversational flow, not just labeling or requesting. It has strong evidence for complex communicators and is sometimes used as a primary system, sometimes as a bridge to high-tech AAC running a PODD-style layout digitally.

Communication books are more comprehensive than single boards but still limited by physical pages. They're bulky to carry. Flipping takes time. For some users, that's fine. For others, the lag between wanting to say something and finding the right page is a real barrier.

Object Communication, Eye Gaze, and the Concrete End of the Spectrum

For users (especially those with significant cognitive or visual impairments) for whom pictures are still too abstract, object-based communication is the starting point. A real spoon means "snack." A real cup means "drink." It is the most concrete form of symbolic communication and often serves as a transitional system as the user develops the ability to interpret pictures.

Eye gaze works at both ends of the tech spectrum. On the low-tech side, a communication partner holds a printed board and reads where the user is looking. For users with motor impairments who cannot point or hand over a card, this is a real, immediate communication mode. (High-tech eye gaze devices from companies like Tobii Dynavox exist too, but they require funding and setup time. A paper board and a willing partner can start today.)

Combining Systems Is the Norm, Not the Exception

Most AAC users who are well-supported end up with a combination:

The combination provides redundancy. It matches the tool to the context. And it means communication access is never fully dependent on one system working perfectly in one moment.

Modeling Makes or Breaks It

Whether high-tech or low-tech, the single factor that most determines success is whether adults model. On a paper board, that means you point to the words as you talk:

"Time for snack. (point to 'want') Do you want goldfish or crackers? (point to each picture)"

Without consistent modeling, a core board is wallpaper. With it, the board becomes a shared language. This applies equally to AAC for autism across the tech spectrum.

Cost, Plainly

For families without immediate access to high-tech funding, this is communication access at the cost of a trip to an office supply store. Use it.

When to Bring In a Professional

For any AAC decision, work with an SLP trained in AAC. They can determine whether low-tech, high-tech, or both fits your child right now; recommend specific systems; train your family on aided language modeling; and help navigate the funding process for high-tech when appropriate. If you don't have access to an AAC-trained SLP locally, many do telehealth evaluations.

What LittleWords Is in This Conversation

LittleWords is not AAC. It is a speech-practice companion. A child using low-tech AAC for daily communication can also use LittleWords for ten minutes a day of verbal speech practice. The two serve different functions and are not in competition. For context on how speech therapy fits alongside AAC, see our speech therapy at home for autistic kids pillar guide.

FAQs

Can my child use only low-tech AAC long-term? Some users do, particularly those who prefer it. For most users with growing communication needs, high-tech AAC eventually becomes the primary system because of vocabulary scope and independence. Low-tech typically stays in the mix as a backup.

Is PECS a substitute for high-tech AAC? PECS works well at certain stages and for certain communicators. Modern AAC research generally recommends moving toward a more comprehensive system (often high-tech) over time. PECS is one tool, not the whole system.

How do I get free low-tech AAC materials? Many SLPs and AAC manufacturers publish free printable core boards. Saltillo, AssistiveWare, and Lessonpix have good resources. Search "free core board" plus a description of your child's communication level.

Will my child understand pictures as a form of communication? Often yes, with consistent modeling. Some users need a more concrete approach (objects) first. An SLP can assess where to start. The key is not waiting for "readiness" but starting with whatever level of representation makes sense now.

Can my child use eye gaze with a paper board? Yes. Low-tech eye gaze is a real, established communication mode. A communication partner holds the board and reads the user's gaze direction. It works for users with motor impairments who cannot point or exchange cards.
