But the U1 could, in theory, help
with more mundane issues too,
such as providing more context for
which device to issue notifications to
depending on how close you are to
it. Or deciding which device should
handle a Siri request. It could be used
to help lead you around an indoor
space, or enhance Apple’s ambitions
in augmented reality by helping it
more precisely locate items in space- perhaps if the company decided, for
 example, that it wants to build wireless
 controllers to work with its AR headset.
 In short, there’s a lot of possibility
 that the U1 chip can unlock. Apple
 clearly believes in that potential,
 given that it sunk the resources
 into designinga chip just for
 ultra-wideband and then built that
 chip into many of its most popular
 devices. Now all it has to do is
 convince the masses.
