Maybe we can use the same strategy as 2fg pinch. Just detect swipe by checking the moving directions of all fingers. Non-swipe gestures are always considered as pinch. There's a big problem with 3-finger pinch gestures that we'll face on many touchpads, particularly the current synaptics generation: we sometimes can't tell the difference between a swipe and a pinch gesture. Unless the thumb is placed down as first or second finger, we won't get positional information and the data stream from a three-finger swipe and three-finger pinch is identical. Until we get RMI4 over SMBus in the kernel, this will be a problem. commit a4adea1646606cd386015ecf13391af3a2a0ccd5 Merge: 82335b0 cab2c16 Author: Peter Hutterer <peter.hutterer@who-t.net> Date: Wed Jan 20 15:38:17 2016 +1000 Merge branch 'wip/3-finger-pinch-gesture' |
