Empowering Access: Tactile AAC Keyguards and High Contrast Symbols for Vision-Impaired Users (LAMP Words for Life iPad Guide)

AAC for Vision-Impaired Clients: Why Standard Setups Fall Short

Supporting AAC users with vision impairment presents unique challenges that standard AAC setups don’t always address:

• Low contrast symbols that are difficult to see
• Flat touchscreens with no tactile guidance
• Difficulty maintaining consistent motor planning
• Limited access to vision-optimised AAC apps on iPad
• Reduced accuracy and increased frustration during communication

For these clients, custom AAC solutions—including tactile keyguards and high contrast symbols—can make a significant difference.

Real Case Study: A Custom AAC Solution in Practice

This solution began with a speech pathologist enquiry about trialling LAMP Words for Life on iPad for a client with vision impairment.

The client required:

• Improved visual accessibility using high contrast AAC symbols
• A way to physically navigate the screen using tactile AAC keyguards

This wasn’t a standard setup—but it’s exactly the type of custom AAC trial solution we specialise in at KimTech.

Designing a Tactile AAC Keyguard for iPad

To support physical access, we designed a custom 3D printed AAC keyguard for iPad with tactile ridges.

Using Volksswitch Keyguard Designer, we were able to:

• Match the keyguard to the LAMP Words for Life layout
• Add raised tactile ridges for navigation and accuracy
• Create a solution tailored to the client’s vision and motor needs

• Provide physical boundaries for screen navigation
• Support users with low vision or motor challenges

Using High Contrast Symbols in LAMP Words for Life (iPad)

The official LAMP Words for Life Vision Impaired (VI) version is only available on Accent devices—not iPads.

However, high contrast AAC symbol modifications for iPad provide an effective alternative.

Customising AAC apps with high contrast symbols

Speech pathologist Angela Moorad (OMazing Kids AAC Consulting) has developed:

• High contrast symbol sets for LAMP Words for Life
• Modifications for apps like GoTalk Now
• Strategies for improving accessibility in AAC apps

These modifications allow clinicians to:

• Improve symbol visibility
• Reduce visual fatigue
• Maintain consistent motor planning
• Adapt AAC systems to individual needs

Common Challenges with AAC for Vision-Impaired Users

When supporting clients with low vision, speech pathologists often encounter:

• AAC apps not designed for visual impairment
• Difficulty maintaining consistent layouts across devices
• Limited awareness of customisation options
• Time constraints in modifying vocabulary systems
• Lack of trial equipment for testing solutions

This is where trial services and custom solutions become essential.

The Importance of AAC Trials and Custom Solutions

AAC trials are essential when working with complex needs, particularly for vision-impaired clients using AAC devices.

They allow you to:

• Test different access methods (visual vs tactile)
• Trial custom keyguards and AAC setups
• Collect functional data for NDIS reports
• Identify the most effective communication system

At KimTech, we support AAC trials across Australia, helping therapists gather the evidence needed for successful outcomes.
