The appletouch driver is prone to reporting multiple fingers when only one is pressing. The appletouch driver queries an array of pressure sensors and counts local maxima in pressure to determine the number of fingers. It just does this on the raw values, so a data stream like: 0 100 250 300 299 300 250 100 0 actually registers as 2 fingers. This patch updates the logic to ignore small dips in pressure that are less than the threshold.Does it still detect 2 fingers as 2 fingers when they are held together?
I just wanted to follow up on this patch[1], since I haven't seen any movement. It's fairly trivial and I've been using it for the past month with great success (yes, it still detects 2 fingers properly). Is there hope that this change can get merged soon?
