iPhone's Future Could Depend on These Breakthrough Technologies

Lucy Edwards, a blind UK-based journalist and broadcaster, found it

difficult to maintain a social distance in public during the height of

the pandemic. That's why she tried the iPhone's People Detection

feature, which uses the iPhone 12 Pro and 13 Pro's lidar sensor to detect when others are nearby.

Lidar, or light detection and ranging, is just one example of how the

technology inside the iPhone has evolved in the last 15 years.

When the first iPhone launched, on June 29, 2007, it had a 3.5-inch screen

that would be considered minuscule by today's standards and a

single 2-megapixel camera. Now Apple's most sophisticated phones come equipped with triple-rear cameras that are advanced enough to shoot films.
