Search the LC Lessons. I found a swipe example here:


but I remember some other lessons that also worked with both swipe and 
taps. Basically, if it isn't a swipe, you implement the tap behavior. 
There are also some lessons on 2-finger swipes in there somewhere. A 
couple that showed up in a search for "2 finger":

Touch interpretation?

[Ben Rubinstein via use-livecode]

Being a lazy sort, until now on mobile apps (which are all for internal use, 
not publication) I've just used the standard controls, and at most tracked 
mousedown/mouseup (for convenience of desktop development) to drag something.


However now I'm trying to make a rather more native-like app, and respond to 
swiping in various directions, and two-finger pinches.


So I've started coding simple heuristics for when a touch sequence is a tap, a 
swipe, or a drag; and the next step is to consider when it is actually a 
two-finger gesture.

libraries developed to implement this? Or at least commonly agreed good 
heuristics?


TIA,

Ben
