Comment 21 for bug 923749

The idea is that you are sustaining a push over a period of time. The important factor is the time. If you open CCSM and adjust the responsiveness slider you will have a shorter required sustained push. We dont have to expose this slider if we can decide on a value for it. Currently it defaults to 1.0f.

The reason your quick swipes dont work is that they dont sustain the pressure for very long. You are applying very high pressure for a very short period of time. So the system sees this as very similar to accidentally cruising into the side when quickly going for the back button. The idea is to show intention. Maybe we currently require too much intention.

The problem is people are trying to push faster, when the correct motion is a slow sustained push. The slider (even if we dont expose it) basically allows you to tweak for sustained push vs higher allowed pressures. The more "responsive" the launcher is, the more prone to false positives it becomes. I have chosen a very conservative value for now, perhaps we should increase the value to 2.0f.
