Yes, and a tap is, technically, a zero length swipe. But there is nevertheless a distinction between taps and swipes just as there is between points and lines.

Yes, and a tap is, technically, a zero length swipe. But there is nevertheless a distinction between taps and swipes just as there is between points and lines. Apple's API distinguishes between the two gestures, even if Apple's lawyers don't. Claiming that tap-to-unlock violates a swipe-to-unlock patent is silly. The whole point of swipe-to-unlock is that a tap doesn't unlock the phone.
- vacri 14y agoThis is what I thought the judge was getting at - yes, you can define a point as a zero-length line in theoretical space, but when you apply it to something like finger movements in the case in front of him, it's a big pile of horseshit. Describing a point as a zero-length line is a mathematical trick used to help understand a concept; it's not a real-world application of mathematics.
