libinput-a...-slot-delta(1) General Commands Manuallibinput-a...-slot-delta(1)

NAME
       libinput-analyze-per-slot-delta	- analyze the per-event	delta movement
       for touch slots

SYNOPSIS
       libinput	analyze	per-slot-delta [--help]	[options] recording.yml

DESCRIPTION
       The libinput analyze per-slot-delta tool	analyzes a recording made with
       libinput	record and prints the delta movement per touch slot.

       This is a debugging tool	only, its output may change at	any  time.  Do
       not rely	on the output.

OPTIONS
       --help  Print help

       --ignore-below=<units or	mm>
	       Ignore any movement below the given threshold. The threshold is
	       in mm if	--use-mm is selected or	in device units	otherwise.

       --threshold=<units or mm>
	       Color  any  movement above this threshold in red. The threshold
	       is in mm	if --use-mm is selected	or in device units otherwise.

       --use-mm
	       Print data in mm	instead	of device units

       --use-st
	       Use the single-touch ABS_X/ABS_Y	instead	of the multitouch axes

       --use-absolute
	       Print absolute coordinates, not deltas

OUTPUT
       An example output for a single finger touch on  a  touchpad  supporting
       two slots is below. This	output is with the use of the --use-mm flag.

	0.000000   +0ms	TOU:	 ++++++	    |  ************* |
	0.021900  +21ms	TOU:  +1.10/+0.14 |  ************* |
	0.033468  +11ms	TOU:  +1.15/+0.19 |  ************* |
	0.043856  +10ms	TOU:  +1.76/+0.22 |  ************* |
	0.053237   +9ms	TOU:  +2.20/+0.19 |  ************* |

       The entry ++++++	indicates a finger has been put	down, ------ indicates
       the  finger has lifted.	The left-most column is	the absolute timestamp
       in seconds.microseconds followed	by the relative	time of	the  event  to
       the previous event.

       The  word  TOU  in this example represents BTN_TOUCH, similar abbrevia-
       tions exist for BTN_TOOL_DOUBLETAP, BTN_TOOL_TRIPLETAP,	BTN_TOOL_QUAD-
       TAP, and	BTN_TOOL_QUINTTAP.

       The arrows indicate the approximate direction on	a 16-point compass, in
       this example EastSouthEast.

       Each  multitouch	 slot  supported by the	hardware has one column, where
       the column shows	asterisk ******** no finger is	down  for  that	 slot.
       Where  the  column  shows  spaces only, a finger	is down	but no data is
       currently available.

       In the above example, the third events occurs ~33ms into	the recording,
       is 11ms after the previous event	and has	an east	south-east  direction.
       The movement for	this event was x: 1.15 and y: 0.19 mm. A second	finger
       is not currently	down.
