人们检测的目的是帮助盲人和低视力用户在导航;这种类型的应用是特别适合于在iPhone 12 Pro中的激光雷达传感器。The goal is to help the visually impaired understand their surroundings — examples include knowing how many people there are in the checkout line at the grocery store, how close one is standing to the end of the platform at the subway station, and finding an empty seat at a table. Another use case is in this era of social distancing; the software can tell you if you’re within six feet of another person in order to maintain courtesy and safety.
Users can set a minimum distance for alerts — say, six feet for the aforementioned social distancing — as well as having an option to use haptic feedback to deliver those notifications. There also is audible feedback; if a person is wearing one AirPod, they will be notified when they’re in close proximity of a person or whatnot. People Detection is fully compatible with VoiceOver, Apple’s screen-reader technology.
