Beyond the Checklist: Rethinking Visual Access for Children with CVI
When we first begin learning about Cortical/Cerebral Visual Impairment (CVI), it can be tempting to look for a checklist.
- Reduce clutter
- Simplify the background
- Make things bigger
- Use familiar objects
- Use high contrast
These strategies can be helpful. But they can also become problematic when we begin treating them as universal rules.
Visual access for a child with CVI is much more individualized than that.
A visual presentation that works beautifully for one child may be inaccessible to another. Even for the same child, what works can change depending on the visual task, the environment, familiarity, complexity, fatigue, sensory demands, and what we are asking the child to do with their vision.
Instead of asking, "Is this CVI-friendly?" we may need to ask a different question:
"Is this visually accessible for this child, for this task, right now?"
That shift changes a lot.
More Contrast Isn't Always More Accessible
High contrast is often one of the first recommendations families hear when discussing visual accessibility.
But contrast and visual accessibility are not the same thing.
Adding a bold outline, brightly colored border, patterned background, or additional high-contrast elements may make something stand out. It may also introduce more visual information for the child to process.
For some children, that additional information can become competition.
This is why we have to look beyond whether something technically has "good contrast" and consider the entire visual scene.
What is the child's attention being drawn toward?
How many visual elements are competing with the target?
Is the added contrast helping define the object, or is it creating another thing the child has to process?
Strong contrast can be extremely helpful for many children with low vision and for some children with CVI. But contrast is only one part of the visual task. If increasing contrast also increases visual complexity or introduces competing information, more contrast may not necessarily create more access.
More contrast does not automatically equal more access.
Sometimes Removing the Background Is Exactly What a Child Needs
There is an important flip side to this conversation.
In our effort to provide meaningful context, we don't want to overlook children who need significant reduction in visual complexity.
For some children with CVI, an object presented against a completely plain background may be far more visually accessible than that same object presented in a more complex or contextual environment.
Imagine a red cup.
We could photograph the cup sitting on a kitchen table next to a plate and napkin. That environment provides meaningful context. It tells us something about what the cup is and how it is used.
But the child may not yet be able to visually process all of that information together.
Place the same red cup alone against a simple background, and suddenly the visual task is very different.
There may be less context, but there is also less competition.
For some children, reducing the background isn't an aesthetic decision. It is an access strategy.
The goal isn't to avoid isolated objects. The goal is to understand when isolation helps the child visually locate, recognize, and process the target.
But Simplifying Can Become Too Simple
As a child's visual processing changes, another question becomes important:
When does context begin to help?
Imagine showing a child a toy car.
One option is to present the car completely isolated against a plain background. That may be the most accessible presentation for some children.
Another option is to place the same car on a simple toy road.
There is now more visual information in the scene, but that additional information has a purpose. The road provides meaningful context for the car.
Now imagine placing that car in a crowded toy bin surrounded by blocks, stuffed animals, balls, puzzle pieces, and other toys.
All three images contain the same car.
But they represent three very different visual tasks.
The target hasn't changed. The visual demand has.
The goal isn't to determine which image is universally "best."
The goal is to determine which level of visual complexity allows the individual child to access the target while providing as much meaningful information as they can successfully process.
Sometimes the answer is complete isolation.
Sometimes it is simple, meaningful context.
Sometimes the child is ready to locate the object within a more complex visual scene.
Accessibility isn't necessarily about making everything as simple as possible. It is about finding the right amount and type of visual information for the learner.
Same Child. Different Visual Task.
Visual access isn't static. Even when we understand how a child typically uses their vision, the demands of the task can change dramatically.
A child may visually attend well in a quiet therapy room but struggle with the same material in a busy classroom. Something accessible in the morning may become much harder when the child is tired. A familiar photograph may be easier to interpret than an unfamiliar representation.
The child's vision hasn't necessarily changed. The visual demand has.
This is why it is so important to consider not only what a child is looking at, but also what we are asking them to do with that visual information.
Are they simply noticing something?
Recognizing it?
Finding it among other objects?
Matching it?
Interpreting what is happening in a scene?
Using vision while simultaneously listening to instructions or completing a motor task?
Those are very different demands.
Sometimes the Problem Isn't the Material
We can spend enormous amounts of time creating an accessible book, worksheet, communication system, or learning material and then place it in an environment that makes accessing it significantly harder.
Imagine a child sitting at a classroom table.
The learning material in front of them may be beautifully simplified. But surrounding it are name cards, pencils, bins, artwork, papers, toys, and other classroom materials.
Children are moving nearby.
An adult is giving verbal directions.
Several objects are being presented at once.
The material itself may not be the problem.
The visual environment may be competing with it.
Sometimes relatively small changes can alter the visual task considerably.
Clear unnecessary materials from the immediate workspace.
Increase spacing between choices.
Reduce competing visual information around the target.
Consider what is happening behind and beside the material.
Give the child adequate processing time.
Be thoughtful about how much verbal information is being provided while the child is also being asked to look.
Instead of asking only, "How can I modify this material?" ask:
"What else is competing for this child's attention right now?"
That question can reveal things we might otherwise miss.
Meaningful and Recognizable Matter, Too
Visual simplicity isn't the only consideration.
We also need to think about whether an image actually communicates useful information to the child.
A beautifully simplified illustration may still be difficult to interpret if the child doesn't recognize what it represents.
A realistic photograph may provide characteristics that help a child connect an image to something they already know.
Meaningful context can sometimes provide additional clues.
Salient features can help distinguish one object from another.
Familiarity can change the difficulty of the visual task.
This is why visual access can't be reduced to background color, image size, or the number of objects on a page.
We have to consider what visual information is actually helping the child understand what they are seeing.
Ask Better Questions
Rather than relying on a universal CVI design checklist, we can begin with questions.
What is the visual target?
Can the child easily determine what they are supposed to look at?
What visual information is necessary?
Which elements help communicate meaning, and which are simply adding complexity?
Is the image meaningful and recognizable to this child?
Does the representation connect to something the child already knows?
What is competing with the target?
Consider objects, patterns, colors, movement, environmental clutter, and other visual information.
Would meaningful context help, or is greater isolation needed?
Consider whether context supports recognition and understanding, or whether it adds more visual information than the child can comfortably process.
What else are we asking the child to do at the same time?
Listening, reaching, communicating, moving, remembering instructions, and visually processing all place demands on the child.
What happens when we change the presentation?
This may be one of the most useful questions of all.
Move the objects farther apart.
Remove something.
Change the background.
Reduce the number of choices.
Use a real photograph.
Add simple, meaningful context.
Give more processing time.
Then watch what happens.
The child's response gives us information.
Put It Into Practice
One of the best ways to understand how changes in visual complexity affect an individual child is simply to experiment, observe, and compare. Try the same familiar object in three different presentations and notice what changes.
Beyond the Checklist
There is no single design that is accessible to every child with CVI.
And that can feel frustrating when what we really want is a clear set of rules.
But it also gives us something much more useful than a checklist.
It gives us permission to observe, adjust, and individualize.
Sometimes access means removing nearly everything from the visual scene.
Sometimes it means carefully adding meaningful context.
Sometimes it means changing the environment rather than the material.
And sometimes the exact same child may need different approaches for different visual tasks.
At Little Dandelion Press, this is something we think about constantly as we create books and learning materials for children with CVI and other visual and developmental differences.
We don't believe accessibility is achieved by checking enough boxes.
We believe it begins by asking better questions:
What does this child need to see?
What might be making that harder?
And what can we change to give them better access?
Because the goal isn't to create something that looks accessible.
The goal is to help the child access it.
