This has irked me because those who don't know anything about touch screen technology don't seem to understand that 'taps' are actually small swipes. The sensors have a far higher resolution than your fingers ability to stay still, so the system rounds down small 'swipes' based on x time over y legnth into what the user meant as taps. It senses the touch down (start point) and the touch up (end point) which may or may not be a zero length swipe or even a small distance swipe.
At a a hardware level and strictly speaking, taps are swipes, Apple just abstracted tiny swipes away into a tap function.
- steve19 14y agoIt irks me that some people who don't know anything about the physics of touch screen technology and don't seem to understand that 'taps' are actually small changes of capacitance of an array of capacitors. [0] At a a physics level, and strictly speaking, taps and swipes don't exist. Patents are pragmatic and full of abstractions. You are not required to specify a patent at every level of abstraction all the way down to its mathematical or quantum properties. (I have to read a number of mechanical patents each week as part of my job). [0] http://en.wikipedia.org/wiki/Capacitive_sensing http://en.wikipedia.org/wiki/Capacitive_sensing
- tsunamifury 14y agoThis is very interesting, thanks for the perspective.
- PGenes 14y agoTaps are not swipes. This has nothing to do with touch screen technology, but about the ordinary, common meaning of "tap" and "swipe". Apple don't get to reassign meanings to common words.
