Fusuma is multitouch gesture recognizer. This gem makes your linux PC able to recognize swipes or pinchs and assign commands to them.
襖(Fusuma) means sliding door used to partition off rooms in a Japanese house.
1. Grant permission to read the touchpad device
IMPORTANT: You MUST be a member of the INPUT group to read touchpad by Fusuma.
$ sudo gpasswd -a $USER input
Then, You MUST LOGOUT/LOGIN or REBOOT to assign this group.
2. Install libinput-tools
libinput release 1.0 or later.
$ sudo apt-get install libinput-tools
3. Install Fusuma
$ sudo gem install fusuma
4. Install xdotool(optional)
For sending shortcuts:
$ sudo apt-get install xdotool
Touchpad not working in GNOME
Ensure the touchpad events are being sent to the GNOME desktop by running the following command:
$ gsettings set org.gnome.desktop.peripherals.touchpad send-events enabled
$ sudo gem update fusuma
Customize Gesture Mapping
You can customize the settings for gestures to put and edit
NOTE: You will need to create the
~/.config/fusuma directory if it doesn't exist yet.
$ mkdir -p ~/.config/fusuma # create config directory $ nano ~/.config/fusuma/config.yml # edit config file.
Example (Gesture Mapping for elementary OS)
swipe: 3: left: command: 'xdotool key alt+Left' right: command: 'xdotool key alt+Right' up: command: 'xdotool key ctrl+t' threshold: 1.5 down: command: 'xdotool key ctrl+w' threshold: 1.5 4: left: command: 'xdotool key super+Left' right: command: 'xdotool key super+Right' up: command: 'xdotool key super+a' down: command: 'xdotool key super+s' pinch: in: command: 'xdotool key ctrl+plus' threshold: 0.1 out: command: 'xdotool key ctrl+minus' threshold: 0.1 threshold: swipe: 1 pinch: 1 interval: swipe: 1 pinch: 1
command: properties are blank, the swipe/pinch doesn't execute command.
threshold: is sensitivity to swipe/pinch. Default value is 1.
If the swipe's threshold is
0.5, shorten swipe-length by half.
interval: is delay between swipes/pinches. Default value is 1.
If the swipe's interval is
0.5, shorten swipe-interval by half to recognize a next swipe.
command: property for assigning commands
On fusuma version 0.4
command: property is available!
You can assign any command each gestures.
shortcut: property is deprecated, it will be removed on fusuma version 1.0.
You need to replace to
swipe: 3: left: - shortcut: 'alt+Left' + command: 'xdotool key alt+Left' right: - shortcut: 'alt+Right' + command: 'xdotool key alt+Right'
--config=path/to/file: Use an alternative config file
--daemon: Daemonize process
--list-devices: List available devices
--verbose: Show details about the results of running fusuma
--device="Device name": Open the given device only
--version: Show fusuma version
- Check the path where you installed fusuma with
$ which fusuma
- Add Fusuma and enter the location where the above path was checked in the command input field
- Add the
-doption at the end of the command input field
