The touch device supports gestures. We can use it also to launch applications.

Define your applications in case section.

# gesture file

#!/bin/sh

# we have 9 gestures
#
# first four
# pinch + up
# pinch + down
# pinch + left
# pinch + right
#
# second four
# stretch + up
# stretch + down
# stretch + left
# stretch + right
#
# pinch + down + up    - emergency assistance :)

usleep 1500000	# -  how long wait for end of gesture

run=`/usr/bin/awk '
BEGIN {a=0; b=0; c=0} {
if ($1==7) a=1 					# -  7 can occur many times
if ($1==3 && c==1) print "9" 
if ($1==4 && a==1) c=1
if ($1==8) b=1 					# -  8 can occur many times
}
END{

It works with Launcher http://yifan.lu/p/kindlelauncher/
I don't know why it isn't working with KUAL. Some hints?

In this way we can open another application without closing app which we currently use. Or launch any script when the lack of access to menu. Many possibilities.

But it's far from perfect. One issue, framework hangs up when book and kterm are opened simultanously. Free to develop.

It starts automaticly after reboot when is on. Off state disable it.

Tested at K5 touch only. Autostart could bring some issue. So, if you have doubts, wait for feedback from other users.
