Topic: Why do we need the mysterious U1 chip in the iPhone 11
In the coming months, everything should change, so how the company announced that it was opening a chip for developers with the new Nearby Interaction framework for iOS 14. It can transmit distance and relative direction between devices equipped with U1.
Apple gave several examples of application:
▪️ Virtual water balls can be placed in the hands of other users in AR
▪️ Taxi applications can more accurately determine the exact location of a user or driver in real time
▪️ In the game, the user can control the fan blade using his device and direct air to another gamer’s moving ball
Owners of iPhones will have to grant permission to detect their devices by neighboring devices every time they open an application with a framework . Random identifiers are generated for each session.
Apple also noted that for maximum recognition accuracy the iPhone should be in portrait orientation. [iMore]
