Test what the user receives
Do not stop at whether captions, alerts, or accessibility controls exist. Test the information and task outcome.
About Lantern Arc
Accessibility engineering that starts with what people actually receive.
Lantern Arc develops software and research tools for testing whether digital and AI systems remain accessible in real use.
Our focus
Find the failure between “feature exists” and “user can actually use it.”
Lantern Arc focuses on whether critical information and communication remain usable for Deaf and Hard-of-Hearing people across AI, software, communication systems, devices, and real-world scenarios.
Measure what gets lost
Look for changed, missing, delayed, or unusable information across audio, text, visual, and haptic experiences.
Connect evidence to fixes
Accessibility engineering should fit into release, regression, remediation, and verification workflows.
Brand architecture
Company → product → capability → workflow.
We keep the structure intentionally simple so customers and contributors know what they are looking at.
Lantern Arc
The parent company and product builder behind the accessibility engineering tools.
DeafAccess
The enterprise accessibility engineering platform and home of the specialized Labs.
DeafBench
The benchmarking and evaluation product, available publicly for open-source and research use.
SignalDesk
The DeafAccess workflow from finding and evidence through assignment, fix, retest, and verification.
Build in public where it helps
Technical criticism makes the work stronger.
DeafBench is open source, and Lantern Arc uses public GitHub repositories when code or documentation is ready to be useful. We would rather improve weak methodology than defend an unsupported claim.
