As you see, event5 is responsible for Touchpad

2) Record events

2.1 run :

adb shell
$ su
$ cd /mnt/sdcard
$ cat /dev/input/event5 > events

2.2 Make your move! swipe or touch ... it's your game

you can stop recording by pressing Ctrl+C

2.3. Play your recording

to play your events, run

$ cat events > /dev/input/event5 

Tada.. That's it! this method is zeroing the timeval ! No delay

The other method is to use x and y coordinates

adb shell input swipe [X1] [Y1] [X2] [Y2] [duration(ms)]

Example :

adb shell input swipe 500 630 714 722 100

The Problem is adb shell input swipe is so slow
