I worked the equivalent gesture for Firefox Metro. For that, I followed microsoft's spec: https://msdn.microsoft.com/en-us/library/windows/apps/hh465299.aspx which might be useful to review if only for comparison and another perspective. They amount to a threshold for intentionality, a threshold to trigger the cross-slide gesture, and a angle/cone which the gesture should fall within to complete - basically, more deltaY than deltaX.
I find the fxos/task-manager recent improvements work really well. But I'm also probably very conditioned by now and not an objective judge. /sam On Thu, Oct 15, 2015 at 5:44 PM, Naoki Hirata <[email protected]> wrote: > Maybe Chris might be able to comment? > > I think he had done work for Firefox for android working with the swiping > motion there and helping to limit the sideways motion when swiping up and > down for scrolling... or maybe that was kats...? > > On Thu, Oct 15, 2015 at 5:26 PM, Sandip Kamat <[email protected]> wrote: > >> I always assumed it was either a device touch-smudge issue (which is >> common for touch devices), or an "angle of swipe" issue.
