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

IMPORTANT: You must be a member of the input group to have permission to read the touchpad device:

$ sudo gpasswd -a $USER input

You must log out and back in or restart to assign this group.

You need libinput release 1.0 or later. Install libinput-tools:

$ sudo apt-get install libinput-tools

For sending shortcuts(optional):

$ sudo apt-get install xdotool

Install Fusuma:

$ gem install fusuma

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

$ gem update fusuma

Customize

You can customize the settings for gestures to put and edit ~/.config/fusuma/config.yml.

Sample (default keymap 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.

Options

• -c, --config=path/to/file : Use an alternative config file
• -d, --daemon : Daemonize process
• -v, --verbose : Show details about the results of running fusuma
• --version : Show fusuma version
