Onscreen HID

Fully customizable onscreen keyboard and touchpad app written in python and HTML.

Features

• customizable UI written in HTML
• full hardware-like keyboard
• touchpad with basic gestures (tap, double tap, scolling, right click)
• option to override system keyboard layout

Installation

• install pywebview from my fork pip install https://github.com/mi4code/pywebview/archive/window-take_focus.zip
• install pynput or keyboard and mouse modules
• then clone this repo and run the oshid.py file

Configuration

there are 3 places where you can edit something

• oshid.py - variables on the begining
• ui.html = UI file There are some CSS variables to make basic customization easier. If you want custom UI you can build your own (just use same ids and callbacks - window.pywebview.api.key_down(<id>); window.pywebview.api.key_up(<id>);).
• keys.csv = layout/key mapping file

Known bugs and limitations

• touchpad doesnt work on all systems (some treat touch as mouse so the mouse pointer gets placed to the touch location)
• dead keys arent currently supported in custom layout mode (as workaround use Unicode combining diacritical marks (U+0301 - U+036F))
• touchpad doesnt support zooming since its not mouse feature

TODOs

• settings GUI
• monitoring caps/num/scroll lock
• dead keys
• handwriting/speech to text
• act as bluetooth/USB HID device (Linux)
• apply layout to hardware keyboard (Windows -> export to *.klc; Linux -> export to ???)
