Choosing the Number of
Locations
Oddly enough, when we start to think about organizing words,
we’ll begin by thinking about how many locations the child
can see or access at one time. Does your child have a visual impairment,
and need very large symbols in order to see them? Is the child
using eye gaze to tell you her words, and you need to limit the
choices so that you can understand which one she’s gazing
at? Does your child access the AAC device using a finger? a fist?
a head pointer? All of these questions will affect how many locations
the child can have access to at one time. In general, using the
most possible locations at a time will give the child the most
words with the least amount of navigating. This makes common sense.
If a child has 32 locations on an overlay, he will have access
to more words without navigating than if he only has 8 locations
per page.
Why is having to navigate a concern? When a child has to navigate
through the device to find the word he wants, at each navigation
point he can lose track of what he is saying or forget where the
words he wants is located. So he must remember longer what he
was trying to say and must remember more steps to get there. In
addition to this cognitive load, the physical act of navigating
through the device slows down an already slow way of communicating.
This can build frustration in a child who desperately wants to
be understood right NOW!
Once you have chosen the number of locations, planning how to
organize the words can begin. In addition to knowing that words
you want on the device right now, planning for growth is critical
to setting up a system that doesn’t need a major overhaul
down the road, in order to still be useful to the child as he
becomes a better communicator and has more things to say. What
words do you want right now?
Choosing the Words
A high frequency list like the Dolch list can
be helpful in choosing those common sentence building words that
we all use every day. (see the references section for a URL for
the Dolch list). Although the Dolch list was assembles to help
with reading instruction, it can be a good resource for AAC, too.
Words like, “on”, “off”, with, under,
good, “bad”, “go”, “do” make
up some the most commonly used words in the English language.
Your child will see these words in print, hear you say them and
can use them to express his thoughts. As an example, Josh went
to the local home improvement store and saw a really cool ceiling
fan with cartoon characters on it. Caleb didn’t go to the
store. When Josh got home, he told us all that he wanted a fan
for his birthday. Caleb was not impressed! He couldn’t understand
why a fan would be a cool gift. So Josh tried to explain “cartoon
fan” then “cartoon tv show fan”. Still Caleb
couldn’t picture it. Finally Josh said “cartoon on
fan”. NOW it made sense to Caleb! The little word “on”
was critical to getting the message across to his brother.
In addition to high frequency words, your child
will need a selection of other words. Most of these will be names
of things. Some of these will be words that everyone uses, and
some will be special for your child. Names of family members,
favorite foods, pets, tv shows and things in your house will be
part of this list.
Another very important word to consider for the
AAC system is the word “not”. By using “not”,
you can really increase the number of things you can say. Not
eat peas. Not play game. Not cold. Not go bed now. Not only does
this little word increase the things you can say, it also increases
your power to interact. Suddenly, “not” allows you
to begin negotiating with your parents. “Not go bed now”
is a great way to begin a conversation that is so typical of young
children who speak. Lots of good interaction skills are learned
when a child negotiates and finds out what can be changed using
words and what is never going to change. For example, Mom may
let me stay up to finish reading a story, but she is NOT going
to let me ride in the car without my car seat. “Not”
can be a scary thing to add to a device, if the people supporting
the device do not respect the value of allowing the child to communicate
his own thoughts. It can also be a wonderfully freeing word to
add to the device, because it forever ends any perception of AAC
as a compliance based skill and firmly cements your child’s
AAC system in the world of “real kid stuff”. Real
kids say not!
Grouping the Words
Now that you are armed with a list of words for
the AAC system, how should they be grouped? I think best when
I am making a mess. One good (messy) way to visualize this is
to write each word on a card and spread them all out on the floor.
Slide the word cards into groups. Pull out a few really important
words or sentence building phrases that should be by themselves
on the main page of the AAC system. Put the others together into
categories. Words that talk about “doing stuff” can
be together. Words that tell where something is can go in the
same group. Toys can go together. Whoops, the toys pile is getting
too big. I’ll break it into piles: books, stuffed animals
and comfort items, general toys, and games.
As you move the cards around, re-group until
you are pretty happy with the grouping. You will most likely end
up with a few stray words. Think about these stray words. Are
they something that is part of a category that you’ll need
later on? For example, very early, we needed to add “telescope”
to the boys’ devices. Where to put it was a puzzle. My husband’s
telescope sits right in our house, so we could call it piece of
furniture. Or, it could have to do with night time. As we thought
about what else might belong with a telescope, we discovered that
there were lots of other things you used with your eyes: cameras,
magnifying glasses, binoculars, microscopes. We decided that “telescope”
was just the first word of a new grouping of words we would call
“things you use with your eyes”, and stored it accordingly,
leaving us a place to put the other words as they became important.
While you may not have a house full of science
geeks and may not own and use this kind of equipment at your house,
chances are you’ll have words that may be the beginning
of a category that will be more important as time goes on. The
boys also have a “web sites” category, to allow them
to communicate about and access their favorite web sites. The
category started with 2 web sites, but now needs to grow to include
youtube and other pre-teen favorites.
Now that you have categories piled on the floor,
it’s time to see if the number of categories you made is
anything near the number of locations you decided on. Hopefully,
it’s close. If you have extra locations on your AAC system,
that’s wonderful! You can think about some sentence starting
phrases to add. “I like”, “do you like”,
“I can”, “I want”, “what’s
that?” or leave blank spots open for new words later on.
If you have more categories than the number of location you chose,
you will need to combine some of the categories. For example,
some of those toys that we broke into separate groups may need
to go back into one group, but we may keep the books separated.
Putting the Word Groups
on the AAC System
Once you have tweaked your piles so you have the
same number of categories as the number of locations you want,
it’s time to think about where to put these on the AAC systems’
main page. Generally, English speakers may want to emphasize starting
a sentence at the left and moving to the right, because this is
an eye pattern that we use when reading. However, it’s also
important to consider what parts of the overlay are easiest to
get to for your child. Kids who use their hands to access the
AAC system may have trouble reaching up and to the corners. kids
who use scanning will want their most used words towards the beginning
of their scanning pattern, so they don’t have to wait long
to get to frequently used words or sentence starters. If you have
a few blank spots, that’s OK. Put them in the places that
are hardest to reach. You can fill them later as the child’s
skills grow.
If you are using a touch screen device, you will
program the main page of the AAC system with sentence starters
and the names of the categories. When a child selects the name
of the category, the page that lists the more specific items in
that category will open up.
If you are using a mid tech and low tech AAC system
with paper pages or overlays, the first page will contain sentence
starters and maybe the names of the categories. Once a category
is selected, the page that lists the more specific items in that
category can be opened. Putting tabs on the side of a communication
book is helpful, as is listing the page number or overlay to turn
to on that category on the main page.

A sample of the main page of a 15
location of a communication book is included here. You’ll
notice that with only 15 locations, there wasn’t room to
include any of the categories on the main page, at all.

In this 16 location example, you can see a page
number on the “friend’s house” location. This
directs you to a page to get more specific details. There is also
a “go to categories” selection, to direct you to the
categories page. These tools are designed to help a partner support
the process of navigating a low tech communication book with many
pages.

In this example of a 64 location board for an
adult who had a stroke, basic sentence building words and many
specific words that were important to her and her caregivers were
included on one page. Notice how much more can be communicated
when there are more locations to choose from.
I hope that this overview has helped to provide
a framework for organizing words on an AAC system for those parents
who need to do so. There are a lot of resources available online:
a few of these are listed in the references section of this article.
I am sure that this topic will continue to generate discussion
on the AAC Parents Google group. Please check out this group to
join in the discussion!
