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 24 What: /sys/bus/hid/drivers/ntrig/<dev>/activation_width 25 What: /sys/bus/hid/drivers/ntrig/<dev>/activation_height 26 Date: May, 2010 27 KernelVersion: 2.6.35 28 Contact: linux-input@vger.kernel.org 29 Description: 30 Threholds to override activation slack. 31 32 ================= ===================================== 33 activation_width (RW) Width threshold to immediately 34 start processing touch events. 35 36 activation_height (RW) Height threshold to immediately 37 start processing touch events. 38 ================= ===================================== 39 40 What: /sys/bus/hid/drivers/ntrig/<dev>/min_width 41 What: /sys/bus/hid/drivers/ntrig/<dev>/min_height 42 Date: May, 2010 43 KernelVersion: 2.6.35 44 Contact: linux-input@vger.kernel.org 45 Description: 46 Minimum size contact accepted. 47 48 ========== =========================================== 49 min_width (RW) Minimum touch contact width to decide 50 activation and activity. 51 52 min_height (RW) Minimum touch contact height to decide 53 activation and activity. 54 ========== =========================================== 55 56 57 What: /sys/bus/hid/drivers/ntrig/<dev>/sensor_physical_width 58 What: /sys/bus/hid/drivers/ntrig/<dev>/sensor_physical_height 59 Date: May, 2010 60 KernelVersion: 2.6.35 61 Contact: linux-input@vger.kernel.org 62 Description: 63 (RO) These are internal ranges not used for normal events but 64 useful for tuning. 65 66 67 What: /sys/bus/hid/drivers/ntrig/<dev>/sensor_logical_width 68 What: /sys/bus/hid/drivers/ntrig/<dev>/sensor_logical_height 69 Date: May, 2010 70 KernelVersion: 2.6.35 71 Contact: linux-input@vger.kernel.org 72 Description: 73 (RO) The range for positions reported during activity.
