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 ================= ===================================== 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 40What: /sys/bus/hid/drivers/ntrig/<dev>/min_width 41What: /sys/bus/hid/drivers/ntrig/<dev>/min_height 42Date: May, 2010 43KernelVersion: 2.6.35 44Contact: linux-input@vger.kernel.org 45Description: 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 57What: /sys/bus/hid/drivers/ntrig/<dev>/sensor_physical_width 58What: /sys/bus/hid/drivers/ntrig/<dev>/sensor_physical_height 59Date: May, 2010 60KernelVersion: 2.6.35 61Contact: linux-input@vger.kernel.org 62Description: 63 (RO) These are internal ranges not used for normal events but 64 useful for tuning. 65 66 67What: /sys/bus/hid/drivers/ntrig/<dev>/sensor_logical_width 68What: /sys/bus/hid/drivers/ntrig/<dev>/sensor_logical_height 69Date: May, 2010 70KernelVersion: 2.6.35 71Contact: linux-input@vger.kernel.org 72Description: 73 (RO) The range for positions reported during activity. 74
