Parce qu'on a quelques tablettes (de dessin) et des PC hybrides (clavier se détachant de l'écran) ou des PC avec écran tactile, autant essayer de les utiliser au mieux.


=== Écran tactile sous Linux ===
L'objectif est d'utiliser au mieux la tablette ou l'écran tactile :
~- idéalement reconnaissance de caractères pour prise de notes
~- dessiner à la va vite des schémas avec une qualité correcte
~- trouver les éléments techniques caractérisant la résolution, la taille de l'équipement, en profiter pour recenser ce qui est possible pour touchpad (certains ont une bonne résolution voire un écran)
~- certaines sont livrées avec un crayon



=== Quelques logiciels spécifiques (ou pas) aux écrans tactiles ===
Il y a bien sûr :
~- xournal https://xournal.sourceforge.net/ Xournal is an application for note taking, sketching, keeping a journal using a stylus. It is similar to Journal or to other alternatives
such as Jarnal, Gournal, and NoteLab.
~- ""xournal++"" https://github.com/xournalpp/xournalpp ""Xournal++"" is a hand note taking software. It supports pen input, e.g. Wacom tablets.

pour du dessin à main levée ou des schémas :
~- essayer drawio
~- drawpile
~- gimp
~-
~-
~- onboard : clavier pour écran tactile
~- openboard : tableau blanc interactif (dérivé de open-sankore)
~-

=== Matériels avec écran tactile ===
netbook Fujitsu Lifebook T series T580 : écran pivotant pour se poser sur le clavier, résolution pas ouf (ça fait des escaliers...), fonctionne mieux avec crayon (perdu)
