Installing Cloud4all/GPII

Cloud4all is developing the technical core of GPII. The efforts are focused on the automatic configuration of devices from user preferences. So it is very common to use Cloud4all and GPII as synonyms, especially when talking about developments.

The instructions in this page mirror the GPII wiki page and they will help you to set up the Cloud4all/GPII in order to use it. If you are a developer or Linux user, and you prefer a detailed setup instructions you are welcome to our blog for developers or the GPII wiki page.

Personas to test with on PCs

These are a couple of tokens to test GPII:

  • Sammy: a user with low vision that needs high contrast and x2 magnification
  • Nisha: a headmouse user that usually combines with an on-screen keyboard

Copy each file to a separate USB and rename them as .gpii-user-token.txt

Then run GPII, run the USB listener and plug the USB in your PC. You will see the two different adaptations launched and configured.
