By holding off on deactivation for a few 20 frames false erroneous disconnects can be tolerated, where the 21 sensor may mistakenly not detect a finger that is still present. 22 23 24What: /sys/bus/hid/drivers/ntrig/<dev>/activation_width 25What: /sys/bus/hid/drivers/ntrig/<dev>/activation_height 26Date: May, 2010 27KernelVersion: 2.6.35 28Contact: linux-input@vger.kernel.org 29Description: 30 Threholds to override activation slack. 31 32 activation_width: (RW) Width threshold to immediately 33 start processing touch events. 34 35 activation_height: (RW) Height threshold to immediately 36 start processing touch events. 37 38 39What: /sys/bus/hid/drivers/ntrig/<dev>/min_width 40What: /sys/bus/hid/drivers/ntrig/<dev>/min_height 41Date: May, 2010 42KernelVersion: 2.6.35 43Contact: linux-input@vger.kernel.org 44Description: 45 Minimum size contact accepted. 46 47 min_width: (RW) Minimum touch contact width to decide 48 activation and activity. 49 50 min_height: (RW) Minimum touch contact height to decide 51 activation and activity. 52 53 54What: /sys/bus/hid/drivers/ntrig/<dev>/sensor_physical_width 55What: /sys/bus/hid/drivers/ntrig/<dev>/sensor_physical_height 56Date: May, 2010 57KernelVersion: 2.6.35 58Contact: linux-input@vger.kernel.org 59Description: 60 (RO) These are internal ranges not used for normal events but 61 useful for tuning. 62 63 64What: /sys/bus/hid/drivers/ntrig/<dev>/sensor_logical_width 65What: /sys/bus/hid/drivers/ntrig/<dev>/sensor_logical_height 66Date: May, 2010 67KernelVersion: 2.6.35 68Contact: linux-input@vger.kernel.org 69Description: 70 (RO) The range for positions reported during activity. 71
