Imran Chaudri—an original iPhone designer—worked on the first iPhone’s user interface, and was once director of Apple’s human interfaces group. He talked to Fast Company about his time at Apple and some of Apple’s flaws.
There are issues any time you do something unnatural, when you ask humanity to interact with machines. It’s that simple. The side effects of interfacing with machines, whether it’s knobs and dials, or clicks and taps, or swipes and gestures, are always going to be there. You have to be smart enough to be ahead of them and anticipate what they are.
Even when using the first iPhone, Mr. Chaudri knew that a feature like Do No Disturb would be important.
