How the iPhone was designed for ‘normal people’ explanation by Greg Christie

You might remember Christie the senior software engineer of Apple.Today on second patent trial against Samsung, he explains some part on the development of the "Slide to Unlock" function Samsung is trying to copying and gave additional details on the development of the original iPhone.  

Recode and CNET have more from Christie’s testimony:

We couldn’t meet our power requirements if we had that active a state,” Apple human-interface head Greg Christie said on Friday, testifying at the Apple-Samsung patent trial. “We had to resort to a power button.” The company was also worried about the phone sending inadvertent emails or “pocket dialing.”

“We knew we had to have a locked mode, or a locked state, where it wouldn’t let you do most things, except you could unlock it.” Christie and his team then worked on a solution, eventually settling on the slide-to-unlock mechanism that shipped on the iPhone and is among the patented features at issue in the case.

Christie said creating the phone took three years. And he also reiterated that developing the iPhone was a serious risk for the company, as it was new territory—something Apple has brought up many times.
