4 Subject: [PATCH 8/8] Send pen-up events faster (side effect: improve illume keyboard responsiveness)
6 Content-Type: text/plain; charset=utf-8
7 Content-Transfer-Encoding: 8bit
9 We were waiting 60ms before reporting a pen-up event to avoid
10 jitter. Now we wait 8ms (actually 5 with HZ == 200).
12 Thanks to Marco Trevisan for testing and pointing out that there was a
13 problem that could be spotted with the illume keyboard.
14 Note that I used the Terminal mode of the keyboard (no dictionary)
17 I also used touch_test.py and the jitter doesn't seem to be an
18 issue when drawing lines with the finger.
