Legal Interpretations can be the Bane of Good Human Factors

Verizon wireless interpreted an accessibility requirement to require they trigger a notification when the user dials 911. Verizon chose to do this audibly… exactly what you DON’T want when you’re calling the police during an emergency!

“The tone our customer experienced is our interpretation of Section 255 of the Telecommunications Act calling for a provider of telecommunications service to offer service that is accessible and usable by individuals with disabilities. The tone, indicating that 911 has been dialed, is one of several features designed to make wireless service is accessible and easy to use, especially for those with disabilities. Other features include a voice command key where customers can use their voice to dial by name or number; a voice echo feature so that a person who can’t see can hear the number or letter if sending a text; read back text messages and speech output of signal strength, battery strength, missed calls, voicemail, roaming, time and date.”

Perhaps there was no time for use cases or personas. “Debbie sees 4 masked men breaking into her home. Trapped, she hides in the closet and dials…. oh. Wait, guys. I think we have a problem.”
