2-year-old Eve from Montrose, Minnesota was aided by Apple's voice assistant Siri to dial for help when her mother had a medical emergency. Mother Liz Neaton has a nervous disorder that causes her to have fainting spells sometimes when she stands up. In her most recent fainting spell, her daughter took her iPhone, pushed and held the home button to call up Siri, who then assisted with the emergency call.
Liz had instructed Eve to use Siri if she has a fainting spell and Eve did just that with a simple action on the iPhone.
Just shows how important a simple and intuitive UI can be in emergency or tight situations.
