The picture at Norwich
The operating setting
Information that works for a hearing passenger may fail for someone who communicates in sign language. Wayfinding at a small airport still involves security, gates and changes to local procedures. An inaccessible fallback would defeat the purpose.
The airport announcement supports the service's existence; it does not demonstrate comprehension or accessibility across every passenger task. For sign-language information to be dependable during disruption, a traveller needs to know whether a display reflects the latest gate instruction and where to seek human help when it does not.

The application and the limits of the evidence
01 / Deployed
Norwich puts an AI sign-language guide in the passenger's path
The operational problem
Deaf travellers need understandable airport instructions and reliable alternatives when an automated message is incomplete.
What the sources report
Norwich Airport's newsroom describes Cassie as an AI sign-language wayfinding service.
Why it matters
The valuable result is whether a traveller understands where to go and what to do at a particular moment.
What remains unprovenIndependent user testing, real-time coverage, language variation and escalation effectiveness are not documented in the current record.
