System: Apple Watch Fall Detection
Model: Not assessed
Release: Not assessed
Application developer: Apple
Role: Not assessed
Configuration: Not assessed
Inputs and outputs: Not assessed
Autonomy: Not assessed
Workflow: An Apple Watch Series 4 or later with Fall Detection switched on (off by default for wearers under 55). A hard fall followed by immobility, or a wearer who confirms the call. Cellular or Wi-Fi connectivity from the watch or a nearby iPhone.
Human oversight: Not assessed
Relation to AI: The watch's fall classifier triggered the 911 call and the location message to his family. Apple's support page says the watch calls automatically only if it detects a hard fall and then immobility for about a minute. The hiker was conscious and spoke to the dispatcher once connected. All sources are news reports from October 2019. The response-count claim is attributed to Middletown police by NBC News.
