Fusuma

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.

Installation

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

You need 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

Usage

$ fusuma

Update

$ sudo gem update fusuma

Customize Gesture Mapping

You can customize the settings for gestures to put and edit ~/.config/fusuma/config.yml.
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'
    down: 
      command: 'xdotool key ctrl+w'
  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'
  out:
    command: 'xdotool key ctrl+minus'

threshold:
  swipe: 1
  pinch: 1

interval:
  swipe: 1
  pinch: 1

if command: properties are blank, the swipe/pinch doesn't trigger 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 command: property.

swipe:
  3: 
    left: 
-      shortcut: 'alt+Left'
+      command: 'xdotool key alt+Left'
    right: 
-      shortcut: 'alt+Right'
+      command: 'xdotool key alt+Right'
